text: Metabotropic γ-aminobutyric acid (GABAB) receptors contribute to the control
of network activity and information processing in hippocampal circuits by regulating
neuronal excitability and synaptic transmission. The dysfunction in the dentate
gyrus (DG) has been implicated in Alzheimer´s disease (AD). Given the involvement
of GABAB receptors in AD, to determine their subcellular localisation and possible
alteration in granule cells of the DG in a mouse model of AD at 12 months of age,
we used high-resolution immunoelectron microscopic analysis. Immunohistochemistry
at the light microscopic level showed that the regional and cellular expression
pattern of GABAB1 was similar in an AD model mouse expressing mutated human amyloid
precursor protein and presenilin1 (APP/PS1) and in age-matched wild type mice.
High-resolution immunoelectron microscopy revealed a distance-dependent gradient
of immunolabelling for GABAB receptors, increasing from proximal to distal dendrites
in both wild type and APP/PS1 mice. However, the overall density of GABAB receptors
at the neuronal surface of these postsynaptic compartments of granule cells was
significantly reduced in APP/PS1 mice. Parallel to this reduction in surface receptors,
we found a significant increase in GABAB1 at cytoplasmic sites. GABAB receptors
were also detected at presynaptic sites in the molecular layer of the DG. We also
found a decrease in plasma membrane GABAB receptors in axon terminals contacting
dendritic spines of granule cells, which was more pronounced in the outer than
in the inner molecular layer. Altogether, our data showing post- and presynaptic
reduction in surface GABAB receptors in the DG suggest the alteration of the GABAB-mediated
modulation of excitability and synaptic transmission in granule cells, which may
contribute to the cognitive dysfunctions in the APP/PS1 model of AD

text: Acute brain slice preparation is a powerful experimental model for investigating
the characteristics of synaptic function in the brain. Although brain tissue is
usually cut at ice-cold temperature (CT) to facilitate slicing and avoid neuronal
damage, exposure to CT causes molecular and architectural changes of synapses.
To address these issues, we investigated ultrastructural and electrophysiological
features of synapses in mouse acute cerebellar slices prepared at ice-cold and
physiological temperature (PT). In the slices prepared at CT, we found significant
spine loss and reconstruction, synaptic vesicle rearrangement and decrease in
synaptic proteins, all of which were not detected in slices prepared at PT. Consistent
with these structural findings, slices prepared at PT showed higher release probability.
Furthermore, preparation at PT allows electrophysiological recording immediately
after slicing resulting in higher detectability of long-term depression (LTD)
after motor learning compared with that at CT. These results indicate substantial
advantages of the slice preparation at PT for investigating synaptic functions
in different physiological conditions.

text: Type 1 metabotropic glutamate receptors (mGluR1s) are key elements in neuronal
signaling. While their function is well documented in slices, requirements for
their activation in vivo are poorly understood. We examine this question in adult
mice in vivo using 2-photon imaging of cerebellar molecular layer interneurons
(MLIs) expressing GCaMP. In anesthetized mice, parallel fiber activation evokes
beam-like Cai rises in postsynaptic MLIs which depend on co-activation of mGluR1s
and ionotropic glutamate receptors (iGluRs). In awake mice, blocking mGluR1 decreases
Cai rises associated with locomotion. In vitro studies and freeze-fracture electron
microscopy show that the iGluR-mGluR1 interaction is synergistic and favored by
close association of the two classes of receptors. Altogether our results suggest
that mGluR1s, acting in synergy with iGluRs, potently contribute to processing
cerebellar neuronal signaling under physiological conditions.

text: Volatile anesthetics are widely used for surgery, but neuronal mechanisms
of anesthesia remain unidentified. At the calyx of Held in brainstem slices from
rats of either sex, isoflurane at clinical doses attenuated EPSCs by decreasing
the release probability and the number of readily releasable vesicles. In presynaptic
recordings of Ca2+ currents and exocytic capacitance changes, isoflurane attenuated
exocytosis by inhibiting Ca2+ currents evoked by a short presynaptic depolarization,
whereas it inhibited exocytosis evoked by a prolonged depolarization via directly
blocking exocytic machinery downstream of Ca2+ influx. Since the length of presynaptic
depolarization can simulate the frequency of synaptic inputs, isoflurane anesthesia
is likely mediated by distinct dual mechanisms, depending on input frequencies.
In simultaneous presynaptic and postsynaptic action potential recordings, isoflurane
impaired the fidelity of repetitive spike transmission, more strongly at higher
frequencies. Furthermore, in the cerebrum of adult mice, isoflurane inhibited
monosynaptic corticocortical spike transmission, preferentially at a higher frequency.
We conclude that dual presynaptic mechanisms operate for the anesthetic action
of isoflurane, of which direct inhibition of exocytic machinery plays a low-pass
filtering role in spike transmission at central excitatory synapses.

text: The hippocampus plays key roles in learning and memory and is a main target
of Alzheimer's disease (AD), which causes progressive memory impairments. Despite
numerous investigations about the processes required for the normal hippocampal
functions, the neurotransmitter receptors involved in the synaptic deficits by
which AD disables the hippocampus are not yet characterized. By combining histoblots,
western blots, immunohistochemistry and high‐resolution immunoelectron microscopic
methods for GABAB receptors, this study provides a quantitative description of
the expression and the subcellular localization of GABAB1 in the hippocampus in
a mouse model of AD at 1, 6 and 12 months of age. Western blots and histoblots
showed that the total amount of protein and the laminar expression pattern of
GABAB1 were similar in APP/PS1 mice and in age‐matched wild‐type mice. In contrast,
immunoelectron microscopic techniques showed that the subcellular localization
of GABAB1 subunit did not change significantly in APP/PS1 mice at 1 month of age,
was significantly reduced in the stratum lacunosum‐moleculare of CA1 pyramidal
cells at 6 months of age and significantly reduced at the membrane surface of
CA1 pyramidal cells at 12 months of age. This reduction of plasma membrane GABAB1
was paralleled by a significant increase of the subunit at the intracellular sites.
We further observed a decrease of membrane‐targeted GABAB receptors in axon terminals
contacting CA1 pyramidal cells. Our data demonstrate compartment‐ and age‐dependent
reduction of plasma membrane‐targeted GABAB receptors in the CA1 region of the
hippocampus, suggesting that this decrease might be enough to alter the GABAB‐mediated
synaptic transmission taking place in AD.

text: "The medial habenula (MHb) is an evolutionary conserved epithalamic structure
important for the modulation of emotional memory. It is involved in regulation
of anxiety, compulsive behavior, addiction (nicotinic and opioid), sexual and
feeding behavior. MHb receives inputs from septal regions and projects exclusively
to the interpeduncular nucleus (IPN). Distinct sub-regions of the septum project
to different subnuclei of MHb: the bed nucleus of anterior commissure projects
to dorsal MHb and the triangular septum projects to ventral MHb. Furthermore,
the dorsal and ventral MHb project to the lateral and rostral/central IPN, respectively.
Importantly, these projections have unique features of prominent co-release of
different neurotransmitters and requirement of a peculiar type of calcium channel
for release. In general, synaptic neurotransmission requires an activity-dependent
influx of Ca2+ into the presynaptic terminal through voltage-gated calcium channels.
The calcium channel family most commonly involved in neurotransmitter release
comprises three members, P/Q-, N- and R-type with Cav2.1, Cav2.2 and Cav2.3 subunits,
respectively. In contrast to most CNS synapses that mainly express Cav2.1 and/or
Cav2.2, MHb terminals in the IPN exclusively express Cav2.3. In other parts of
the brain, such as the hippocampus, Cav2.3 is mostly located to postsynaptic elements.
This unusual presynaptic location of Cav2.3 in the MHb-IPN pathway implies unique
mechanisms of glutamate release in this pathway. One potential example of such
uniqueness is the facilitation of release by GABAB receptor (GBR) activation.
Presynaptic GBRs usually inhibit the release of neurotransmitters by inhibiting
presynaptic calcium channels. MHb shows the highest expression levels of GBR in
the brain. GBRs comprise two subunits, GABAB1 (GB1) and GABAB2 (GB2), and are
associated with auxiliary subunits, called potassium channel tetramerization domain
containing proteins (KCTD) 8, 12, 12b and 16. Among these four subunits, KCTD12b
is exclusively expressed in ventral MHb, and KCTD8 shows the strongest expression
in the whole MHb among other brain regions, indicating that KCTD8 and KCTD12b
may be involved in the unique mechanisms of neurotransmitter release mediated
by Cav2.3 and regulated by GBRs in this pathway. \r\nIn the present study, we
first verified that neurotransmission in both dorsal and ventral MHb-IPN pathways
is mainly mediated by Cav2.3 using a selective blocker of R-type channels, SNX-482.
We next found that baclofen, a GBR agonist, has facilitatory effects on release
from ventral MHb terminal in rostral IPN, whereas it has inhibitory effects on
release from dorsal MHb terminals in lateral IPN, indicating that KCTD12b expressed
exclusively in ventral MHb may have a role in the facilitatory effects of GBR
activation. In a heterologous expression system using HEK cells, we found that
KCTD8 and KCTD12b but not KCTD12 directly bind with Cav2.3. Pre-embedding immunogold
electron microscopy data show that Cav2.3 and KCTD12b are distributed most densely
in presynaptic active zone in IPN with KCTD12b being present only in rostral/central
but not lateral IPN, whereas GABAB, KCTD8 and KCTD12 are distributed most densely
in perisynaptic sites with KCTD12 present more frequently in postsynaptic elements
and only in rostral/central IPN. In freeze-fracture replica labelling, Cav2.3,
KCTD8 and KCTD12b are co-localized with each other in the same active zone indicating
that they may form complexes regulating vesicle release in rostral IPN. \r\nOn
electrophysiological studies of wild type (WT) mice, we found that paired-pulse
ratio in rostral IPN of KCTD12b knock-out (KO) mice is lower than those of WT
and KCTD8 KO mice. Consistent with this finding, in mean variance analysis, release
probability in rostral IPN of KCTD12b KO mice is higher than that of WT and KCTD8
KO mice. Although paired-pulse ratios are not different between WT and KCTD8 KO
mice, the mean variance analysis revealed significantly lower release probability
in rostral IPN of KCTD8 KO than WT mice. These results demonstrate bidirectional
regulation of Cav2.3-mediated release by KCTD8 and KCTD12b without GBR activation
in rostral IPN. Finally, we examined the baclofen effects in rostral IPN of KCTD8
and KCTD12b KO mice, and found the facilitation of release remained in both KO
mice, indicating that the peculiar effects of the GBR activation in this pathway
do not depend on the selective expression of these KCTD subunits in ventral MHb.
However, we found that presynaptic potentiation of evoked EPSC amplitude by baclofen
falls to baseline after washout faster in KCTD12b KO mice than WT, KCTD8 KO and
KCTD8/12b double KO mice. This result indicates that KCTD12b is involved in sustained
potentiation of vesicle release by GBR activation, whereas KCTD8 is involved in
its termination in the absence of KCTD12b. Consistent with these functional findings,
replica labelling revealed an increase in density of KCTD8, but not Cav2.3 or
GBR at active zone in rostral IPN of KCTD12b KO mice compared with that of WT
mice, suggesting that increased association of KCTD8 with Cav2.3 facilitates the
release probability and termination of the GBR effect in the absence of KCTD12b.\r\nIn
summary, our study provided new insights into the physiological roles of presynaptic
Cav2.3, GBRs and their auxiliary subunits KCTDs at an evolutionary conserved neuronal
circuit. Future studies will be required to identify the exact molecular mechanism
underlying the GBR-mediated presynaptic potentiation on ventral MHb terminals.
It remains to be determined whether the prominent presence of presynaptic KCTDs
at active zone could exert similar neuromodulatory functions in different pathways
of the brain.\r\n"

text: The molecular anatomy of synapses defines their characteristics in transmission
and plasticity. Precise measurements of the number and distribution of synaptic
proteins are important for our understanding of synapse heterogeneity within and
between brain regions. Freeze–fracture replica immunogold electron microscopy
enables us to analyze them quantitatively on a two-dimensional membrane surface.
Here, we introduce Darea software, which utilizes deep learning for analysis of
replica images and demonstrate its usefulness for quick measurements of the pre-
and postsynaptic areas, density and distribution of gold particles at synapses
in a reproducible manner. We used Darea for comparing glutamate receptor and calcium
channel distributions between hippocampal CA3-CA1 spine synapses on apical and
basal dendrites, which differ in signaling pathways involved in synaptic plasticity.
We found that apical synapses express a higher density of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic
acid (AMPA) receptors and a stronger increase of AMPA receptors with synaptic
size, while basal synapses show a larger increase in N-methyl-D-aspartate (NMDA)
receptors with size. Interestingly, AMPA and NMDA receptors are segregated within
postsynaptic sites and negatively correlated in density among both apical and
basal synapses. In the presynaptic sites, Cav2.1 voltage-gated calcium channels
show similar densities in apical and basal synapses with distributions consistent
with an exclusion zone model of calcium channel-release site topography.

text: Chemical labeling of proteins with synthetic molecular probes offers the possibility
to probe the functions of proteins of interest in living cells. However, the methods
for covalently labeling targeted proteins using complementary peptide tag-probe
pairs are still limited, irrespective of the versatility of such pairs in biological
research. Herein, we report the new CysHis tag-Ni(II) probe pair for the specific
covalent labeling of proteins. A broad-range evaluation of the reactivity profiles
of the probe and the CysHis peptide tag afforded a tag-probe pair with an optimized
and high labeling selectivity and reactivity. In particular, the labeling specificity
of this pair was notably improved compared to the previously reported one. This
pair was successfully utilized for the fluorescence imaging of membrane proteins
on the surfaces of living cells, demonstrating its potential utility in biological
research.

text: "Hyperpolarization-activated cyclic-nucleotide-gated (HCN) channels control
electrical rhythmicity and excitability in the heart and brain, but the function
of HCN channels at the subcellular level in axons remains poorly understood. Here,
we show that the action potential conduction velocity in both myelinated and unmyelinated
central axons can be bidirectionally modulated by a HCN channel blocker, cyclic
adenosine monophosphate (cAMP), and neuromodulators. Recordings from mouse cerebellar
mossy fiber boutons show that HCN channels ensure reliable high-frequency firing
and are strongly modulated by cAMP (EC50 40 mM; estimated endogenous cAMP concentration
13 mM). In addition, immunogold-electron microscopy revealed HCN2 as the dominating
subunit in cerebellar mossy fibers. Computational modeling indicated that HCN2
channels control conduction velocity primarily by altering the resting membrane
potential\r\nand are associated with significant metabolic costs. These results
suggest that the cAMP-HCN pathway provides neuromodulators with an opportunity
to finely tune energy consumption and temporal delays across axons in the brain."

text: Glutamate is the major excitatory neurotransmitter in the CNS binding to a
variety of glutamate receptors. Metabotropic glutamate receptors (mGluR1 to mGluR8)
can act excitatory or inhibitory, depending on associated signal cascades. Expression
and localization of inhibitory acting mGluRs at inner hair cells (IHCs) in the
cochlea are largely unknown. Here, we analyzed expression of mGluR2, mGluR3, mGluR4,
mGluR6, mGluR7, and mGluR8 and investigated their localization with respect to
the presynaptic ribbon of IHC synapses. We detected transcripts for mGluR2, mGluR3,
and mGluR4 as well as for mGluR7a, mGluR7b, mGluR8a, and mGluR8b splice variants.
Using receptor-specific antibodies in cochlear wholemounts, we found expression
of mGluR2, mGluR4, and mGluR8b close to presynaptic ribbons. Super resolution
and confocal microscopy in combination with 3-dimensional reconstructions indicated
a postsynaptic localization of mGluR2 that overlaps with postsynaptic density
protein 95 on dendrites of afferent type I spiral ganglion neurons. In contrast,
mGluR4 and mGluR8b were expressed at the presynapse close to IHC ribbons. In summary,
we localized in detail 3 mGluR types at IHC ribbon synapses, providing a fundament
for new therapeutical strategies that could protect the cochlea against noxious
stimuli and excitotoxicity.

text: 'Transporters of the solute carrier 6 (SLC6) family translocate their cognate
substrate together with Na+ and Cl−. Detailed kinetic models exist for the transporters
of GABA (GAT1/SLC6A1) and the monoamines dopamine (DAT/SLC6A3) and serotonin (SERT/SLC6A4).
Here, we posited that the transport cycle of individual SLC6 transporters reflects
the physiological requirements they operate under. We tested this hypothesis by
analyzing the transport cycle of glycine transporter 1 (GlyT1/SLC6A9) and glycine
transporter 2 (GlyT2/SLC6A5). GlyT2 is the only SLC6 family member known to translocate
glycine, Na+, and Cl− in a 1:3:1 stoichiometry. We analyzed partial reactions
in real time by electrophysiological recordings. Contrary to monoamine transporters,
both GlyTs were found to have a high transport capacity driven by rapid return
of the empty transporter after release of Cl− on the intracellular side. Rapid
cycling of both GlyTs was further supported by highly cooperative binding of cosubstrate
ions and substrate such that their forward transport mode was maintained even
under conditions of elevated intracellular Na+ or Cl−. The most important differences
in the transport cycle of GlyT1 and GlyT2 arose from the kinetics of charge movement
and the resulting voltage-dependent rate-limiting reactions: the kinetics of GlyT1
were governed by transition of the substrate-bound transporter from outward- to
inward-facing conformations, whereas the kinetics of GlyT2 were governed by Na+
binding (or a related conformational change). Kinetic modeling showed that the
kinetics of GlyT1 are ideally suited for supplying the extracellular glycine levels
required for NMDA receptor activation.'

text: Electron microscopy (EM) is a technology that enables visualization of single
proteins at a nanometer resolution. However, current protein analysis by EM mainly
relies on immunolabeling with gold-particle-conjugated antibodies, which is compromised
by large size of antibody, precluding precise detection of protein location in
biological samples. Here, we develop a specific chemical labeling method for EM
detection of proteins at single-molecular level. Rational design of α-helical
peptide tag and probe structure provided a complementary reaction pair that enabled
specific cysteine conjugation of the tag. The developed chemical labeling with
gold-nanoparticle-conjugated probe showed significantly higher labeling efficiency
and detectability of high-density clusters of tag-fused G protein-coupled receptors
in freeze-fracture replicas compared with immunogold labeling. Furthermore, in
ultrathin sections, the spatial resolution of the chemical labeling was significantly
higher than that of antibody-mediated labeling. These results demonstrate substantial
advantages of the chemical labeling approach for single protein visualization
by EM.

text: 'The small-conductance, Ca2+-activated K+ (SK) channel subtype SK2 regulates
the spike rate and firing frequency, as well as Ca2+ transients in Purkinje cells
(PCs). To understand the molecular basis by which SK2 channels mediate these functions,
we analyzed the exact location and densities of SK2 channels along the neuronal
surface of the mouse cerebellar PCs using SDS-digested freeze-fracture replica
labeling (SDS-FRL) of high sensitivity combined with quantitative analyses. Immunogold
particles for SK2 were observed on post- and pre-synaptic compartments showing
both scattered and clustered distribution patterns. We found an axo-somato-dendritic
gradient of the SK2 particle density increasing 12-fold from soma to dendritic
spines. Using two different immunogold approaches, we also found that SK2 immunoparticles
were frequently adjacent to, but never overlap with, the postsynaptic density
of excitatory synapses in PC spines. Co-immunoprecipitation analysis demonstrated
that SK2 channels form macromolecular complexes with two types of proteins that
mobilize Ca2+: CaV2.1 channels and mGlu1α receptors in the cerebellum. Freeze-fracture
replica double-labeling showed significant co-clustering of particles for SK2
with those for CaV2.1 channels and mGlu1α receptors. SK2 channels were also detected
at presynaptic sites, mostly at the presynaptic active zone (AZ), where they are
close to CaV2.1 channels, though they are not significantly co-clustered. These
data demonstrate that SK2 channels located in different neuronal compartments
can associate with distinct proteins mobilizing Ca2+, and suggest that the ultrastructural
association of SK2 with CaV2.1 and mGlu1α provides the mechanism that ensures
voltage (excitability) regulation by distinct intracellular Ca2+ transients in
PCs.'

text: Three-dimensional (3D) super-resolution microscopy technique structured illumination
microscopy (SIM) imaging of dendritic spines along the dendrite has not been previously
performed in fixed tissues, mainly due to deterioration of the stripe pattern
of the excitation laser induced by light scattering and optical aberrations. To
address this issue and solve these optical problems, we applied a novel clearing
reagent, LUCID, to fixed brains. In SIM imaging, the penetration depth and the
spatial resolution were improved in LUCID-treated slices, and 160-nm spatial resolution
was obtained in a large portion of the imaging volume on a single apical dendrite.
Furthermore, in a morphological analysis of spine heads of layer V pyramidal neurons
(L5PNs) in the medial prefrontal cortex (mPFC) of chronic dexamethasone (Dex)-treated
mice, SIM imaging revealed an altered distribution of spine forms that could not
be detected by high-NA confocal imaging. Thus, super-resolution SIM imaging represents
a promising high-throughput method for revealing spine morphologies in single
dendrites.

text: Although dopamine receptors D1 and D2 play key roles in hippocampal function,
their synaptic localization within the hippocampus has not been fully elucidated.
In order to understand precise functions of pre- or postsynaptic dopamine receptors
(DRs), the development of protocols to differentiate pre- and postsynaptic DRs
is essential. So far, most studies on determination and quantification of DRs
did not discriminate between subsynaptic localization. Therefore, the aim of the
study was to generate a robust workflow for the localization of DRs. This work
provides the basis for future work on hippocampal DRs, in light that DRs may have
different functions at pre- or postsynaptic sites. Synaptosomes from rat hippocampi
isolated by a sucrose gradient protocol were prepared for super-resolution direct
stochastic optical reconstruction microscopy (dSTORM) using Bassoon as a presynaptic
zone and Homer1 as postsynaptic density marker. Direct labeling of primary validated
antibodies against dopamine receptors D1 (D1R) and D2 (D2R) with Alexa Fluor 594
enabled unequivocal assignment of D1R and D2R to both, pre- and postsynaptic sites.
D1R immunoreactivity clusters were observed within the presynaptic active zone
as well as at perisynaptic sites at the edge of the presynaptic active zone. The
results may be useful for the interpretation of previous studies and the design
of future work on DRs in the hippocampus. Moreover, the reduction of the complexity
of brain tissue by the use of synaptosomal preparations and dSTORM technology
may represent a useful tool for synaptic localization of brain proteins.

text: For ultrafast fixation of biological samples to avoid artifacts, high-pressure
freezing (HPF) followed by freeze substitution (FS) is preferred over chemical
fixation at room temperature. After HPF, samples are maintained at low temperature
during dehydration and fixation, while avoiding damaging recrystallization. This
is a notoriously slow process. McDonald and Webb demonstrated, in 2011, that sample
agitation during FS dramatically reduces the necessary time. Then, in 2015, we
(H.G. and S.R.) introduced an agitation module into the cryochamber of an automated
FS unit and demonstrated that the preparation of algae could be shortened from
days to a couple of hours. We argued that variability in the processing, reproducibility,
and safety issues are better addressed using automated FS units. For dissemination,
we started low-cost manufacturing of agitation modules for two of the most widely
used FS units, the Automatic Freeze Substitution Systems, AFS(1) and AFS2, from
Leica Microsystems, using three dimensional (3D)-printing of the major components.
To test them, several labs independently used the modules on a wide variety of
specimens that had previously been processed by manual agitation, or without agitation.
We demonstrate that automated processing with sample agitation saves time, increases
flexibility with respect to sample requirements and protocols, and produces data
of at least as good quality as other approaches.

text: Asymmetries have long been known about in the central nervous system. From
gross anatomical differences, such as the presence of the parapineal organ in
only one hemisphere of the developing zebrafish, to more subtle differences in
activity between both hemispheres, as seen in freely roaming animals or human
participants under PET and fMRI imaging analysis. The presence of asymmetries
has been demonstrated to have huge behavioural implications, with their disruption
often leading to the generation of neurological disorders, memory problems, changes
in personality, and in an organism's health and well-being. For my Ph.D. work
I aimed to tackle two important avenues of research. The first being the process
of input-side dependency in the hippocampus, with the goal of finding a key gene
responsible for its development (Gene X). The second project was to do with experience-induced
laterality formation in the hippocampus. Specifically, how laterality in the synapse
density of the CA1 stratum radiatum (s.r.) could be induced purely through environmental
enrichment. Through unilateral tracer injections into the CA3, I was able to selectively
measure the properties of synapses within the CA1 and investigate how they differed
based upon which hemisphere the presynaptic neurone originated. Having found the
existence of a previously unreported reversed (left-isomerism) i.v. mutant, through
morpholocal examination of labelled terminals in the CA1 s.r., I aimed to elucidate
a key gene responsible for the process of left or right determination of inputs
to the CA1 s.r.. This work relates to the previous finding of input-side dependent
asymmetry in the wild-type rodent, where the origin of the projecting neurone
to the CA1 will determine the morphology of a synapse, to a greater degree than
the hemisphere in which the projection terminates. Using left- and right-isomerism
i.v. mice, in combination with whole genome sequence analysis, I highlight Ena/VASP-like
(Evl) as a potential target for Gene X. In relation to this topic, I also highlight
my work in the recently published paper of how knockout of PirB can lead to a
lack of input-side dependency in the murine hippocampus. For the second question,
I show that the environmental enrichment paradigm will lead to an asymmetry in
the synapse densities in the hippocampus of mice. I also highlight that the nature
of the enrichment is of less consequence than the process of enrichment itself.
I demonstrate that the CA3 region will dramatically alter its projection targets,
in relation to environmental stimulation, with the asymmetry in synaptic density,
caused by enrichment, relying heavily on commissural fibres. I also highlight
the vital importance of input-side dependent asymmetry, as a necessary component
of experience-dependent laterality formation in the CA1 s.r.. However, my results
suggest that it isn't the only cause, as there appears to be a CA1 dependent mechanism
also at play. Upon further investigation, I highlight the significant, and highly
important, finding that the changes seen in the CA1 s.r. were predominantly caused
through projections from the left-CA3, with the right-CA3 having less involvement
in this mechanism.

text: Metabotropic GABAB receptors mediate slow inhibitory effects presynaptically
and postsynaptically through the modulation of different effector signalling pathways.
Here, we analysed the distribution of GABAB receptors using highly sensitive SDS-digested
freeze-fracture replica labelling in mouse cerebellar Purkinje cells. Immunoreactivity
for GABAB1 was observed on presynaptic and, more abundantly, on postsynaptic compartments,
showing both scattered and clustered distribution patterns. Quantitative analysis
of immunoparticles revealed a somato-dendritic gradient, with the density of immunoparticles
increasing 26-fold from somata to dendritic spines. To understand the spatial
relationship of GABAB receptors with two key effector ion channels, the G protein-gated
inwardly rectifying K+ (GIRK/Kir3) channel and the voltage-dependent Ca2+ channel,
biochemical and immunohistochemical approaches were performed. Co-immunoprecipitation
analysis demonstrated that GABAB receptors co-assembled with GIRK and CaV2.1 channels
in the cerebellum. Using double-labelling immunoelectron microscopic techniques,
co-clustering between GABAB1 and GIRK2 was detected in dendritic spines, whereas
they were mainly segregated in the dendritic shafts. In contrast, co-clustering
of GABAB1 and CaV2.1 was detected in dendritic shafts but not spines. Presynaptically,
although no significant co-clustering of GABAB1 and GIRK2 or CaV2.1 channels was
detected, inter-cluster distance for GABAB1 and GIRK2 was significantly smaller
in the active zone than in the dendritic shafts, and that for GABAB1 and CaV2.1
was significantly smaller in the active zone than in the dendritic shafts and
spines. Thus, GABAB receptors are associated with GIRK and CaV2.1 channels in
different subcellular compartments. These data provide a better framework for
understanding the different roles played by GABAB receptors and their effector
ion channels in the cerebellar network.

text: It has been reported that nicotinamide-overload induces oxidative stress associated
with insulin resistance, the key feature of type 2 diabetes mellitus (T2DM). This
study aimed to investigate the effects of B vitamins in T2DM. Glucose tolerance
tests (GTT) were carried out in adult Sprague-Dawley rats treated with or without
cumulative doses of B vitamins. More specifically, insulin tolerance tests (ITT)
were also carried out in adult Sprague-Dawley rats treated with or without cumulative
doses of Vitamin B3. We found that cumulative Vitamin B1 and Vitamin B3 administration
significantly increased the plasma H2O2 levels associated with high insulin levels.
Only Vitamin B3 reduced muscular and hepatic glycogen contents. Cumulative administration
of nicotinic acid, another form of Vitamin B3, also significantly increased plasma
insulin level and H2O2 generation. Moreover, cumulative administration of nicotinic
acid or nicotinamide impaired glucose metabolism. This study suggested that excess
Vitamin B1 and Vitamin B3 caused oxidative stress and insulin resistance.

text: 'Many central synapses contain a single presynaptic active zone and a single
postsynaptic density. Vesicular release statistics at such “simple synapses” indicate
that they contain a small complement of docking sites where vesicles repetitively
dock and fuse. In this work, we investigate functional and morphological aspects
of docking sites at simple synapses made between cerebellar parallel fibers and
molecular layer interneurons. Using immunogold labeling of SDS-treated freeze-fracture
replicas, we find that Cav2.1 channels form several clusters per active zone with
about nine channels per cluster. The mean value and range of intersynaptic variation
are similar for Cav2.1 cluster numbers and for functional estimates of docking-site
numbers obtained from the maximum numbers of released vesicles per action potential.
Both numbers grow in relation with synaptic size and decrease by a similar extent
with age between 2 wk and 4 wk postnatal. Thus, the mean docking-site numbers
were 3.15 at 2 wk (range: 1–10) and 2.03 at 4 wk (range: 1–4), whereas the mean
numbers of Cav2.1 clusters were 2.84 at 2 wk (range: 1–8) and 2.37 at 4 wk (range:
1–5). These changes were accompanied by decreases of miniature current amplitude
(from 93 pA to 56 pA), active-zone surface area (from 0.0427 μm2 to 0.0234 μm2),
and initial success rate (from 0.609 to 0.353), indicating a tightening of synaptic
transmission with development. Altogether, these results suggest a close correspondence
between the number of functionally defined vesicular docking sites and that of
clusters of voltage-gated calcium channels. '

text: Adipose tissues play key roles in energy homeostasis. Brown adipocytes and
beige adipocytes in white adipose tissue (WAT) share the similar characters of
thermogenesis, both of them could be potential targets for obesity management.
Several thermo-sensitive transient receptor potential channels (thermoTRPs) are
shown to be involved in adipocyte biology. However, the expression pattern of
thermoTRPs in adipose tissues from obese mice is still unknown. The mRNA expression
of thermoTRPs in subcutaneous WAT (sWAT) and interscapular brown adipose tissue
(iBAT) from lean and obese mice were measured using reverse transcriptase-quantitative
PCRs (RT-qPCR). The results demonstrated that all 10 thermoTRPs are expressed
in both iBAT and sWAT, and without significant difference in the mRNA expression
level of thermoTRPs between these two tissues. Moreover, Trpv1 and Trpv3 mRNA
expression levels in both iBAT and sWAT were significantly decreased in high fat
diet (HFD)-induced obese mice and db/db (leptin receptor deficient) mice. Trpm2
mRNA expression level was significantly decreased only in sWAT from HFD-induced
obese mice and db/db mice. On the other hand, Trpv2 and Trpv4 mRNA expression
levels in iBAT and sWAT were significantly increased in HFD-induced obese mice
and db/db mice. Taken together, we conclude that all 10 thermoTRPs are expressed
in iBAT and sWAT. And several thermoTRPs differentially expressed in adipose tissues
from HFD-induced obese mice and db/db mice, suggesting a potential involvement
in anti-obesity regulations.

text: The neurotransmitter receptor subtype, number, density, and distribution relative
to the location of transmitter release sites are key determinants of signal transmission.
AMPA-type ionotropic glutamate receptors (AMPARs) containing GluA3 and GluA4 subunits
are prominently expressed in subsets of neurons capable of firing action potentials
at high frequencies, such as auditory relay neurons. The auditory nerve (AN) forms
glutamatergic synapses on two types of relay neurons, bushy cells (BCs) and fusiform
cells (FCs) of the cochlear nucleus. AN-BC and AN-FC synapses have distinct kinetics;
thus, we investigated whether the number, density, and localization of GluA3 and
GluA4 subunits in these synapses are differentially organized using quantitative
freeze-fracture replica immunogold labeling. We identify a positive correlation
between the number of AMPARs and the size of AN-BC and AN-FC synapses. Both types
of AN synapses have similar numbers of AMPARs; however, the AN-BC have a higher
density of AMPARs than AN-FC synapses, because the AN-BC synapses are smaller.
A higher number and density of GluA3 subunits are observed at AN-BC synapses,
whereas a higher number and density of GluA4 subunits are observed at AN-FC synapses.
The intrasynaptic distribution of immunogold labeling revealed that AMPAR subunits,
particularly GluA3, are concentrated at the center of the AN-BC synapses. The
central distribution of AMPARs is absent in GluA3-knockout mice, and gold particles
are evenly distributed along the postsynaptic density. GluA4 gold labeling was
homogenously distributed along both synapse types. Thus, GluA3 and GluA4 subunits
are distributed at AN synapses in a target-cell-dependent manner.

text: 'Developments in bioengineering and molecular biology have introduced a palette
of genetically encoded probes for identification of specific cell populations
in electron microscopy. These probes can be targeted to distinct cellular compartments,
rendering them electron dense through a subsequent chemical reaction. These electron
densities strongly increase the local contrast in samples prepared for electron
microscopy, allowing three major advances in ultrastructural mapping of circuits:
genetic identification of circuit components, targeted imaging of regions of interest
and automated analysis of the tagged circuits. Together, the gains from these
advances can decrease the time required for the analysis of targeted circuit motifs
by over two orders of magnitude. These genetic encoded tags for electron microscopy
promise to simplify the analysis of circuit motifs and become a central tool for
structure‐function studies of synaptic connections in the brain. We review the
current state‐of‐the‐art with an emphasis on connectomics, the quantitative analysis
of neuronal structures and motifs.'

text: Metabotropic glutamate receptor subtype 5 (mGluR5) is crucially implicated
in the pathophysiology of Fragile X Syndrome (FXS); however, its dysfunction at
the sub-cellular level, and related synaptic and cognitive phenotypes are unexplored.
Here, we probed the consequences of mGluR5/Homer scaffold disruption for mGluR5
cell-surface mobility, synaptic N-methyl-D-Aspartate receptor (NMDAR) function,
and behavioral phenotypes in the second-generation Fmr1 knockout (KO) mouse. Using
single-molecule tracking, we found that mGluR5 was significantly more mobile at
synapses in hippocampal Fmr1 KO neurons, causing an increased synaptic surface
co-clustering of mGluR5 and NMDAR. This correlated with a reduced amplitude of
synaptic NMDAR currents, a lack of their mGluR5-Activated long-Term depression,
and NMDAR/hippocampus dependent cognitive deficits. These synaptic and behavioral
phenomena were reversed by knocking down Homer1a in Fmr1 KO mice. Our study provides
a mechanistic link between changes of mGluR5 dynamics and pathological phenotypes
of FXS, unveiling novel targets for mGluR5-based therapeutics.

text: 'Aim: The present study was to compare the effects of nicotinic acid and nicotinamide
on the plasma methyl donors, choline and betaine. Methods: Thirty adult subjects
were randomly divided into three groups of equal size, and orally received purified
water (C group), nicotinic acid (300 mg, NA group) or nicotinamide (300 mg, NM
group). Plasma nicotinamide, N 1-methylnicotinamide, homocysteine, betaine and
choline levels before and 1.5-h and 3-h post-dosing, plasma normetanephrine and
metanephrine concentrations at 3-h post-dosing, and the urinary excretion of N
1-methyl-2-pyridone-5-carboxamide during the test period were examined. Results:
The level of 3-h plasma nicotinamide, N 1-methylnicotinamide, homocysteine, the
urinary excretion of N 1-methyl-2-pyridone-5-carboxamide and pulse pressure (PP)
in the NM group was 221%, 3972%, 61%, 1728% and 21.2% higher than that of the
control group (P < 0.01, except homocysteine and PP P < 0.05), while the
3-h plasma betaine, normetanephrine and metanephrine level in the NM group was
24.4%, 9.4% and 11.7% lower (P < 0.05, except betaine P < 0.01), without
significant difference in choline levels. Similar but less pronounced changes
were observed in the NA group, with a lower level of 3-h plasma N 1-methylnicotinamide
(1.90 ± 0.20 μmol/l vs. 3.62 ± 0.27 μmol/l, P < 0.01) and homocysteine (12.85
± 1.39 μmol/l vs. 18.08 ± 1.02 μmol/l, P < 0.05) but a higher level of betaine
(27.44 ± 0.71 μmol/l vs. 23.52 ± 0.61 μmol/l, P < 0.05) than that of the NM
group. Conclusion: The degradation of nicotinamide consumes more betaine than
that of nicotinic acid at identical doses. This difference should be taken into
consideration in niacin fortification. © 2016 Elsevier Ltd and European Society

text: Beige adipocytes are a new type of recruitable brownish adipocytes, with highly
mitochondrial membrane uncoupling protein 1 expression and thermogenesis. Beige
adipocytes were found among white adipocytes, especially in subcutaneous white
adipose tissue (sWAT). Therefore, beige adipocytes may be involved in the regulation
of energy metabolism and fat deposition. Transient receptor potential melastatin
8 (TRPM8), a Ca2+-permeable non-selective cation channel, plays vital roles in
the regulation of various cellular functions. It has been reported that TRPM8
activation enhanced the thermogenic function of brown adiposytes. However, the
involvement of TRPM8 in the thermogenic function of WAT remains unexplored. Our
data revealed that TRPM8 was expressed in mouse white adipocytes at mRNA, protein
and functional levels. The mRNA expression of Trpm8 was significantly increased
in the differentiated white adipocytes than pre-adipocytes. Moreover, activation
of TRPM8 by menthol enhanced the expression of thermogenic genes in cultured white
aidpocytes. And menthol-induced increases of the thermogenic genes in white adipocytes
was inhibited by either KT5720 (a protein kinase A inhibitor) or BAPTA-AM. In
addition, high fat diet (HFD)-induced obesity in mice was significantly recovered
by co-treatment with menthol. Dietary menthol enhanced WAT "browning"
and improved glucose metabolism in HFD-induced obesity mice as well. Therefore,
we concluded that TRPM8 might be involved in WAT "browning" by increasing
the expression levels of genes related to thermogenesis and energy metabolism.
And dietary menthol could be a novel approach for combating human obesity and
related metabolic diseases.

text: Left-right asymmetry is a fundamental feature of higher-order brain structure;
however, the molecular basis of brain asymmetry remains unclear. We recently identified
structural and functional asymmetries in mouse hippocampal circuitry that result
from the asymmetrical distribution of two distinct populations of pyramidal cell
synapses that differ in the density of the NMDA receptor subunit GluRε2 (also
known as NR2B, GRIN2B or GluN2B). By examining the synaptic distribution of ε2
subunits, we previously found that β2-microglobulin-deficient mice, which lack
cell surface expression of the vast majority of major histocompatibility complex
class I (MHCI) proteins, do not exhibit circuit asymmetry. In the present study,
we conducted electrophysiological and anatomical analyses on the hippocampal circuitry
of mice with a knockout of the paired immunoglobulin-like receptor B (PirB), an
MHCI receptor. As in β2-microglobulin-deficient mice, the PirB-deficient hippocampus
lacked circuit asymmetries. This finding that MHCI loss-of-function mice and PirB
knockout mice have identical phenotypes suggests that MHCI signals that produce
hippocampal asymmetries are transduced through PirB. Our results provide evidence
for a critical role of the MHCI/PirB signaling system in the generation of asymmetries
in hippocampal circuitry.

text: ' Cholecystokinin-expressing interneurons (CCK-INs) mediate behavior state-dependent
inhibition in cortical circuits and themselves receive strong GABAergic input.
However, it remains unclear to what extent GABABreceptors (GABABRs) contribute
to their inhibitory control. Using immunoelectron microscopy, we found that CCK-INs
in the rat hippocampus possessed high levels of dendritic GABABRs and KCTD12 auxiliary
proteins, whereas postsynaptic effector Kir3 channels were present at lower levels.
Consistently, whole-cell recordings revealed slow GABABR-mediated inhibitory postsynaptic
currents (IPSCs) in most CCK-INs. In spite of the higher surface density of GABABRs
in CCK-INs than in CA1 principal cells, the amplitudes of IPSCs were comparable,
suggesting that the expression of Kir3 channels is the limiting factor for the
GABABR currents in these INs. Morphological analysis showed that CCK-INs were
diverse, comprising perisomatic-targeting basket cells (BCs), as well as dendrite-targeting
(DT) interneurons, including a previously undescribed DT type. GABABR-mediated
IPSCs in CCK-INs were large in BCs, but small in DT subtypes. In response to prolonged
activation, GABABR-mediated currents displayed strong desensitization, which was
absent in KCTD12-deficient mice. This study highlights that GABABRs differentially
control CCK-IN subtypes, and the kinetics and desensitization of GABABR-mediated
currents are modulated by KCTD12 proteins. '

text: Adaptations of vestibulo-ocular and optokinetic response eye movements have
been studied as an experimental model of cerebellum-dependent motor learning.
Several previous physiological and pharmacological studies have consistently suggested
that the cerebellar flocculus (FL) Purkinje cells (P-cells) and the medial vestibular
nucleus (MVN) neurons targeted by FL (FL-targeted MVN neurons) may respectively
maintain the memory traces of short- and long-term adaptation. To study the basic
structures of the FL-MVN synapses by light microscopy (LM) and electron microscopy
(EM), we injected green florescence protein (GFP)-expressing lentivirus into FL
to anterogradely label the FL P-cell axons in C57BL/6J mice. The FL P-cell axonal
boutons were distributed in the magnocellular MVN and in the border region of
parvocellular MVN and prepositus hypoglossi (PrH). In the magnocellular MVN, the
FL-P cell axons mainly terminated on somata and proximal dendrites. On the other
hand, in the parvocellular MVN/PrH, the FL P-cell axonal synaptic boutons mainly
terminated on the relatively small-diameter (< 1 μm) distal dendrites of MVN
neurons, forming symmetrical synapses. The majority of such parvocellular MVN/PrH
neurons were determined to be glutamatergic by immunocytochemistry and in-situ
hybridization of GFP expressing transgenic mice. To further examine the spatial
relationship between the synapses of FL P-cells and those of vestibular nerve
on the neurons of the parvocellular MVN/ PrH, we added injections of biotinylated
dextran amine into the semicircular canal and anterogradely labeled vestibular
nerve axons in some mice. The MVN dendrites receiving the FL P-cell axonal synaptic
boutons often closely apposed vestibular nerve synaptic boutons in both LM and
EM studies. Such a partial overlap of synaptic boutons of FL P-cell axons with
those of vestibular nerve axons in the distal dendrites of MVN neurons suggests
that inhibitory synapses of FL P-cells may influence the function of neighboring
excitatory synapses of vestibular nerve in the parvocellular MVN/PrH neurons.

text: Immunogold labeling of freeze-fracture replicas has recently been used for
high-resolution visualization of protein localization in electron microscopy.
This method has higher labeling efficiency than conventional immunogold methods
for membrane molecules allowing precise quantitative measurements. However, one
of the limitations of freeze-fracture replica immunolabeling is difficulty in
keeping structural orientation and identifying labeled profiles in complex tissues
like brain. The difficulty is partly due to fragmentation of freeze-fracture replica
preparations during labeling procedures and limited morphological clues on the
replica surface. To overcome these issues, we introduce here a grid-glued replica
method combined with SEM observation. This method allows histological staining
before dissolving the tissue and easy handling of replicas during immunogold labeling,
and keeps the whole replica surface intact without fragmentation. The procedure

text: Synaptic efficacy and precision are influenced by the coupling of voltage-gated
Ca2+ channels (VGCCs) to vesicles. But because the topography of VGCCs and their
proximity to vesicles is unknown, a quantitative understanding of the determinants
of vesicular release at nanometer scale is lacking. To investigate this, we combined
freeze-fracture replica immunogold labeling of Cav2.1 channels, local [Ca2+] imaging,
and patch pipette perfusion of EGTA at the calyx of Held. Between postnatal day
7 and 21, VGCCs formed variable sized clusters and vesicular release became less
sensitive to EGTA, whereas fixed Ca2+ buffer properties remained constant. Experimentally
constrained reaction-diffusion simulations suggest that Ca2+ sensors for vesicular
release are located at the perimeter of VGCC clusters (<30nm) and predict that
VGCC number per cluster determines vesicular release probability without altering
release time course. This "perimeter release model" provides a unifying
framework accounting for developmental changes in both synaptic efficacy and time
course.

text: γ-Aminobutyric acid (GABA)- and glycine-mediated hyperpolarizing inhibition
is associated with a chloride influx that depends on the inwardly directed chloride
electrochemical gradient. In neurons, the extrusion of chloride from the cytosol
primarily depends on the expression of an isoform of potassium-chloride cotransporters
(KCC2s). KCC2 is crucial in the regulation of the inhibitory tone of neural circuits,
including pain processing neural assemblies. Thus we investigated the cellular
distribution of KCC2 in neurons underlying pain processing in the superficial
spinal dorsal horn of rats by using high-resolution immunocytochemical methods.
We demonstrated that perikarya and dendrites widely expressed KCC2, but axon terminals
proved to be negative for KCC2. In single ultrathin sections, silver deposits
labeling KCC2 molecules showed different densities on the surface of dendritic
profiles, some of which were negative for KCC2. In freeze fracture replicas and
tissue sections double stained for the β3-subunit of GABAA receptors and KCC2,
GABAA receptors were revealed on dendritic segments with high and also with low
KCC2 densities. By measuring the distances between spots immunoreactive for gephyrin
(a scaffolding protein of GABAA and glycine receptors) and KCC2 on the surface
of neurokinin 1 (NK1) receptor-immunoreactive dendrites, we found that gephyrin-immunoreactive
spots were located at various distances from KCC2 cotransporters; 5.7 % of them
were recovered in the middle of 4-10-μm-long dendritic segments that were free
of KCC2 immunostaining. The variable local densities of KCC2 may result in variable
postsynaptic potentials evoked by the activation of GABAA and glycine receptors
along the dendrites of spinal neurons.

text: Major histocompatibility complex class I (MHCI) molecules were recently identified
as novel regulators of synaptic plasticity. These molecules are expressed in various
brain areas, especially in regions undergoing activity-dependent synaptic plasticity,
but their role in the nucleus accumbens (NAc) is unknown. In this study, we investigated
the effects of genetic disruption of MHCI function, through deletion of β2-microblobulin,
which causes lack of cell surface expression of MHCI. First, we confirmed that
MHCI molecules are expressed in the NAc core in wild-type mice. Second, we performed
electrophysiological recordings with NAc core slices from wild-type and β2-microglobulin
knock-out mice lacking cell surface expression of MHCI. We found that low frequency
stimulation induced long-term depression in wild-type but not knock-out mice,
whereas high frequency stimulation induced long-term potentiation in both genotypes,
with a larger magnitude in knock-out mice. Furthermore, we demonstrated that knock-out
mice showed more persistent behavioral sensitization to cocaine, which is a NAc-related
behavior. Using this model, we analyzed the density of total AMPA receptors and
their subunits GluR1 and GluR2 in the NAc core, by SDS-digested freeze-fracture
replica labeling. After repeated cocaine exposure, the density of GluR1 was increased,
but there was no change in total AMPA receptors and GluR2 levels in wildtype mice.
In contrast, following repeated cocaine exposure, increased densities of total
AMPA receptors, GluR1 and GluR2 were observed in knock-out mice. These results
indicate that functional deficiency of MHCI enhances synaptic potentiation, induced
by electrical and pharmacological stimulation.

text: Fast synaptic transmission is important for rapid information processing.
To explore the maximal rate of neuronal signaling and to analyze the presynaptic
mechanisms, we focused on the input layer of the cerebellar cortex, where exceptionally
high action potential (AP) frequencies have been reported invivo. With paired
recordings between presynaptic cerebellar mossy fiber boutons and postsynaptic
granule cells, we demonstrate reliable neurotransmission upto ~1 kHz. Presynaptic
APs are ultrafast, with ~100μs half-duration. Both Kv1 and Kv3 potassium channels
mediate the fast repolarization, rapidly inactivating sodium channels ensure metabolic
efficiency, and little AP broadening occurs during bursts of up to 1.5 kHz. Presynaptic
Cav2.1 (P/Q-type) calcium channels open efficiently during ultrafast APs. Furthermore,
a subset of synaptic vesicles is tightly coupled to Ca2+ channels, and vesicles
are rapidly recruited to the release site. These data reveal mechanisms of presynaptic
AP generation and transmitter release underlying neuronal kHz signaling.

text: Cerebellar motor learning is suggested to be caused by long-term plasticity
of excitatory parallel fiber-Purkinje cell (PF-PC) synapses associated with changes
in the number of synaptic AMPA-type glutamate receptors (AMPARs). However, whether
the AMPARs decrease or increase in individual PF-PC synapses occurs in physiological
motor learning and accounts for memory that lasts over days remains elusive. We
combined quantitative SDS-digested freeze-fracture replica labeling for AMPAR
and physical dissector electron microscopy with a simple model of cerebellar motor
learning, adaptation of horizontal optokinetic response (HOKR) in mouse. After
1-h training of HOKR, short-term adaptation (STA) was accompanied with transient
decrease in AMPARs by 28% in target PF-PC synapses. STA was well correlated with
AMPAR decrease in individual animals and both STA and AMPAR decrease recovered
to basal levels within 24 h. Surprisingly, long-termadaptation (LTA) after five
consecutive daily trainings of 1-h HOKR did not alter the number of AMPARs in
PF-PC synapses but caused gradual and persistent synapse elimination by 45%, with
corresponding PC spine loss by the fifth training day. Furthermore, recovery of
LTA after 2 wk was well correlated with increase of PF-PC synapses to the control
level. Our findings indicate that the AMPARs decrease in PF-PC synapses and the
elimination of these synapses are in vivo engrams in short- and long-term motor
learning, respectively, showing a unique type of synaptic plasticity that may
contribute to memory consolidation.

text: Long-lasting memories are formed when the stimulus is temporally distributed
(spacing effect). However, the synaptic mechanisms underlying this robust phenomenon
and the precise time course of the synaptic modifications that occur during learning
remain unclear. Here we examined the adaptation of horizontal optokinetic response
in mice that underwent 1 h of massed and spaced training at varying intervals.
Despite similar acquisition by all training protocols, 1 h of spacing produced
the highest memory retention at 24 h, which lasted for 1 mo. The distinct kinetics
of memory are strongly correlated with the reduction of floccular parallel fiber-Purkinje
cell synapses but not with AMPA receptor (AMPAR) number and synapse size. After
the spaced training, we observed 25%, 23%, and 12% reduction in AMPAR density,
synapse size, and synapse number, respectively. Four hours after the spaced training,
half of the synapses and Purkinje cell spines had been eliminated, whereas AMPAR
density and synapse size were recovered in remaining synapses. Surprisingly, massed
training also produced long-term memory and halving of synapses; however, this
occurred slowly over days, and the memory lasted for only 1 wk. This distinct
kinetics of structural plasticity may serve as a basis for unique temporal profiles
in the formation and decay of memory with or without intervals.

text: The development of the vertebrate brain requires an exquisite balance between
proliferation and differentiation of neural progenitors. Notch signaling plays
a pivotal role in regulating this balance, yet the interaction between signaling
and receiving cells remains poorly understood. We have found that numerous nascent
neurons and/or intermediate neurogenic progenitors expressing the ligand of Notch
retain apical endfeet transiently at the ventricular lumen that form adherens
junctions (AJs) with the endfeet of progenitors. Forced detachment of the apical
endfeet of those differentiating cells by disrupting AJs resulted in precocious
neurogenesis that was preceded by the downregulation of Notch signaling. Both
Notch1 and its ligand Dll1 are distributed around AJs in the apical endfeet, and
these proteins physically interact with ZO-1, a constituent of the AJ. Furthermore,
live imaging of a fluorescently tagged Notch1 demonstrated its trafficking from
the apical endfoot to the nucleus upon cleavage. Our results identified the apical
endfoot as the central site of active Notch signaling to securely prohibit inappropriate
differentiation of neural progenitors.

text: Synaptic cell adhesion molecules are increasingly gaining attention for conferring
specific properties to individual synapses. Netrin-G1 and netrin-G2 are trans-synaptic
adhesion molecules that distribute on distinct axons, and their presence restricts
the expression of their cognate receptors, NGL1 and NGL2, respectively, to specific
subdendritic segments of target neurons. However, the neural circuits and functional
roles of netrin-G isoform complexes remain unclear. Here, we use netrin-G-KO and
NGL-KO mice to reveal that netrin-G1/NGL1 and netrin-G2/NGL2 interactions specify
excitatory synapses in independent hippocampal pathways. In the hippocampal CA1
area, netrin-G1/NGL1 and netrin-G2/NGL2 were expressed in the temporoammonic and
Schaffer collateral pathways, respectively. The lack of presynaptic netrin-Gs
led to the dispersion of NGLs from postsynaptic membranes. In accord, netrin-G
mutant synapses displayed opposing phenotypes in long-term and short-term plasticity
through discrete biochemical pathways. The plasticity phenotypes in netrin-G-KOs
were phenocopied in NGL-KOs, with a corresponding loss of netrin-Gs from presynaptic
membranes. Our findings show that netrin-G/NGL interactions differentially control
synaptic plasticity in distinct circuits via retrograde signaling mechanisms and
explain how synaptic inputs are diversified to control neuronal activity.

text: We examined the synaptic structure, quantity, and distribution of α-amino-3-hydroxy-5-methylisoxazole-4-propionic
acid (AMPA)- and N-methyl-D-aspartate (NMDA)-type glutamate receptors (AMPARs
and NMDARs, respectively) in rat cochlear nuclei by a highly sensitive freeze-fracture
replica labeling technique. Four excitatory synapses formed by two distinct inputs,
auditory nerve (AN) and parallel fibers (PF), on different cell types were analyzed.
These excitatory synapse types included AN synapses on bushy cells (AN-BC synapses)
and fusiform cells (AN-FC synapses) and PF synapses on FC (PF-FC synapses) and
cartwheel cell spines (PF-CwC synapses). Immunogold labeling revealed differences
in synaptic structure as well as AMPAR and NMDAR number and/or density in both
AN and PF synapses, indicating a target-dependent organization. The immunogold
receptor labeling also identified differences in the synaptic organization of
FCs based on AN or PF connections, indicating an input-dependent organization
in FCs. Among the four excitatory synapse types, the AN-BC synapses were the smallest
and had the most densely packed intramembrane particles (IMPs), whereas the PF-CwC
synapses were the largest and had sparsely packed IMPs. All four synapse types
showed positive correlations between the IMP-cluster area and the AMPAR number,
indicating a common intrasynapse-type relationship for glutamatergic synapses.
Immunogold particles for AMPARs were distributed over the entire area of individual
AN synapses; PF synapses often showed synaptic areas devoid of labeling. The gold-labeling
for NMDARs occurred in a mosaic fashion, with less positive correlations between
the IMP-cluster area and the NMDAR number. Our observations reveal target- and
input-dependent features in the structure, number, and organization of AMPARs
and NMDARs in AN and PF synapses.

text: 'The brain demands high-energy supply and obstruction of blood flow causes
rapid deterioration of the healthiness of brain cells. Two major events occur
upon ischemia: acidosis and liberation of excess glutamate, which leads to excitotoxicity.
However, cellular source of glutamate and its release mechanism upon ischemia
remained unknown. Here we show a causal relationship between glial acidosis and
neuronal excitotoxicity. As the major cation that flows through channelrhodopsin-2
(ChR2) is proton, this could be regarded as an optogenetic tool for instant intracellular
acidification. Optical activation of ChR2 expressed in glial cells led to glial
acidification and to release of glutamate. On the other hand, glial alkalization
via optogenetic activation of a proton pump, archaerhodopsin (ArchT), led to cessation
of glutamate release and to the relief of ischemic brain damage in vivo. Our results
suggest that controlling glial pH may be an effective therapeutic strategy for
intervention of ischemic brain damage.'
