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: Primary neuronal cell culture preparations are widely used to investigate
synaptic functions. This chapter describes a detailed protocol for the preparation
of a neuronal cell culture in which giant calyx-type synaptic terminals are formed.
This chapter also presents detailed protocols for utilizing the main technical
advantages provided by such a preparation, namely, labeling and imaging of synaptic
organelles and electrophysiological recordings directly from presynaptic terminals.

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. '
