A diverse array of AMPAR signalling complexes are established by receptor auxiliary subunits, which associate with the AMPAR in various combinations to modulate trafficking, gating and synaptic strength2. However, their mechanisms of action are poorly understood. Here we determine cryo-electron microscopy structures of the heteromeric GluA1–GluA2 receptor assembled with both TARP-γ8 and CNIH2, the predominant AMPAR complex in the forebrain, in both resting and active states. Two TARP-γ8 and two CNIH2 subunits insert at distinct sites beneath the ligand-binding domains of the receptor, with site-specific lipids shaping each interaction and affecting the gating regulation of the AMPARs. Activation of the receptor leads to asymmetry between GluA1 and GluA2 along the ion conduction path and an outward expansion of the channel triggers counter-rotations of both auxiliary subunit pairs, promoting the active-state conformation. In addition, both TARP-γ8 and CNIH2 pivot towards the pore exit upon activation, extending their reach for cytoplasmic receptor elements. CNIH2 achieves this through its uniquely extended M2 helix, which has transformed this endoplasmic reticulum-export factor into a powerful AMPAR modulator that is capable of providing hippocampal pyramidal neurons with their integrative synaptic properties.

Post-tetanic potentiation (PTP) is the most powerful form of plasticity at this synaptic connection. It is widely believed that mossy fiber PTP is an entirely presynaptic phenomenon, implying that PTP induction is input-specific, and requires neither activity of multiple inputs nor stimulation of postsynaptic neurons. To directly test cooperativity and associativity, we made paired recordings between single mossy fiber terminals and postsynaptic CA3 pyramidal neurons in rat brain slices. By stimulating non-overlapping mossy fiber inputs converging onto single CA3 neurons, we confirm that PTP is input-specific and non-cooperative. Unexpectedly, mossy fiber PTP exhibits anti-associative induction properties. EPSCs show only minimal PTP after combined pre- and postsynaptic high-frequency stimulation with intact postsynaptic Ca2+ signaling, but marked PTP in the absence of postsynaptic spiking and after suppression of postsynaptic Ca2+ signaling (10 mM EGTA). PTP is largely recovered by inhibitors of voltage-gated R- and L-type Ca2+ channels, group II mGluRs, and vacuolar-type H+-ATPase, suggesting the involvement of retrograde vesicular glutamate signaling. Transsynaptic regulation of PTP extends the repertoire of synaptic computations, implementing a brake on mossy fiber detonation and a “smart teacher” function of hippocampal mossy fiber synapses."}],"issue":"1","type":"journal_article","acknowledged_ssus":[{"_id":"SSU"}],"language":[{"iso":"eng"}],"doi":"10.1038/s41467-021-23153-5","isi":1,"quality_controlled":"1","project":[{"_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","grant_number":"692692","name":"Biophysics and circuit function of a giant cortical glumatergic synapse","call_identifier":"H2020"},{"_id":"25C5A090-B435-11E9-9278-68D0E5697425","grant_number":"Z00312","call_identifier":"FWF","name":"The Wittgenstein Prize"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000655481800014"]},"oa":1,"month":"05","publication_identifier":{"issn":["2041-1723"]},"date_updated":"2023-08-10T14:16:16Z","date_created":"2021-08-06T07:22:55Z","volume":12,"author":[{"first_name":"David H","last_name":"Vandael","id":"3AE48E0A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7577-1676","full_name":"Vandael, David H"},{"first_name":"Yuji","last_name":"Okamoto","id":"3337E116-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0408-6094","full_name":"Okamoto, Yuji"},{"full_name":"Jonas, Peter M","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5001-4804","first_name":"Peter M","last_name":"Jonas"}],"related_material":{"link":[{"url":"https://ist.ac.at/en/news/synaptic-transmission-not-a-one-way-street/","description":"News on IST Homepage","relation":"press_release"}]},"publication_status":"published","publisher":"Springer","department":[{"_id":"PeJo"}],"acknowledgement":"We thank Drs.

Changes in AMPAR localisation can enact synaptic plasticity, allowing long-term information storage, and is therefore tightly controlled. Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but with limited coherence or comparison between reports, our understanding of this process is unclear. Here, combining synaptic recordings from mouse hippocampal slices and super-resolution imaging in dissociated cultures, we compare the contributions of three AMPAR interaction domains controlling transmission at hippocampal CA1 synapses. We show that the AMPAR C-termini play only a modulatory role, whereas the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission. Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density, where the NTD further tunes their positioning. This interplay between cytosolic (TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate synaptic transmission and plasticity.","lang":"eng"}],"type":"journal_article","file":[{"access_level":"open_access","file_name":"2021_NatureCommunications_Watson.pdf","creator":"cchlebak","content_type":"application/pdf","file_size":18310502,"file_id":"9991","relation":"main_file","success":1,"checksum":"1bf4f6a561f96bc426d754de9cb57710","date_updated":"2021-09-08T12:57:06Z","date_created":"2021-09-08T12:57:06Z"}],"oa_version":"Published Version","_id":"9985","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","intvolume":" 12","title":"AMPA receptor anchoring at CA1 synapses is determined by N-terminal domain and TARP γ8 interactions","status":"public","ddc":["612"]},{"scopus_import":"1","has_accepted_license":"1","article_processing_charge":"No","day":"01","page":"2947–2967","article_type":"original","citation":{"chicago":"Vandael, David H, Yuji Okamoto, Carolina Borges Merjane, Victor M Vargas Barroso, Benjamin Suter, and Peter M Jonas. “Subcellular Patch-Clamp Techniques for Single-Bouton Stimulation and Simultaneous Pre- and Postsynaptic Recording at Cortical Synapses.” Nature Protocols.

However, this has been achieved at only a limited number of model synapses, including the squid giant synapse and the mammalian calyx of Held. Cortical presynaptic terminals have been largely inaccessible to direct presynaptic recording, due to their small size. Here, we describe a protocol for improved subcellular patch-clamp recording in rat and mouse brain slices, with the synapse in a largely intact environment. Slice preparation takes ~2 h, recording ~3 h and post hoc morphological analysis 2 d. Single presynaptic hippocampal mossy fiber terminals are stimulated minimally invasively in the bouton-attached configuration, in which the cytoplasmic content remains unperturbed, or in the whole-bouton configuration, in which the cytoplasmic composition can be precisely controlled. Paired pre–postsynaptic recordings can be integrated with biocytin labeling and morphological analysis, allowing correlative investigation of synapse structure and function. Paired recordings can be obtained from mossy fiber terminals in slices from both rats and mice, implying applicability to genetically modified synapses. Paired recordings can also be performed together with axon tract stimulation or optogenetic activation, allowing comparison of unitary and compound synaptic events in the same target cell. Finally, paired recordings can be combined with spontaneous event analysis, permitting collection of miniature events generated at a single identified synapse. In conclusion, the subcellular patch-clamp techniques detailed here should facilitate analysis of biophysics, plasticity and circuit function of cortical synapses in the mammalian central nervous system.","lang":"eng"}],"intvolume":" 16","ddc":["570"],"status":"public","title":"Subcellular patch-clamp techniques for single-bouton stimulation and simultaneous pre- and postsynaptic recording at cortical synapses","_id":"9438","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file":[{"checksum":"7eb580abd8893cdb0b410cf41bc8c263","date_updated":"2021-12-02T23:30:05Z","date_created":"2021-07-08T12:27:55Z","relation":"main_file","embargo":"2021-12-01","file_id":"9639","content_type":"application/pdf","file_size":38574802,"creator":"cziletti","access_level":"open_access","file_name":"VandaeletalAuthorVersion2021.pdf"}],"oa_version":"Submitted Version","publication_identifier":{"eissn":["17502799"],"issn":["17542189"]},"month":"06","project":[{"grant_number":"692692","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Biophysics and circuit function of a giant cortical glumatergic synapse"},{"_id":"25C5A090-B435-11E9-9278-68D0E5697425","grant_number":"Z00312","call_identifier":"FWF","name":"The Wittgenstein Prize"},{"call_identifier":"FWF","name":"Structural plasticity at mossy fiber-CA3 synapses","grant_number":"V00739","_id":"2696E7FE-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","isi":1,"external_id":{"isi":["000650528700003"],"pmid":["33990799"]},"oa":1,"language":[{"iso":"eng"}],"acknowledged_ssus":[{"_id":"M-Shop"}],"doi":"10.1038/s41596-021-00526-0","ec_funded":1,"file_date_updated":"2021-12-02T23:30:05Z","publisher":"Springer Nature","department":[{"_id":"PeJo"}],"publication_status":"published","pmid":1,"acknowledgement":"This project received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement no. 692692 to P.J.) and the Fond zur Förderung der Wissenschaftlichen Forschung (Z 312-B27, Wittgenstein award to P.J., V 739-B27 to C.B.M.).

Activation of GBRs facilitates or inhibits transmitter release from MHb terminals depending on the IPN subnucleus, but the role of KCTDs is unknown. We therefore examined the localization and function of Cav2.3, GBRs, and KCTDs in this pathway in mice. We show in heterologous cells that KCTD8 and KCTD12b directly bind to Cav2.3 and that KCTD8 potentiates Cav2.3 currents in the absence of GBRs. In the rostral IPN, KCTD8, KCTD12b, and Cav2.3 co-localize at the presynaptic active zone. Genetic deletion indicated a bidirectional modulation of Cav2.3-mediated release by these KCTDs with a compensatory increase of KCTD8 in the active zone in KCTD12b-deficient mice.

Although PTP has a uniquely large magnitude at hippocampal mossy fiber-CA3 pyramidal neuron synapses, it is unclear whether it can be induced by natural activity and whether its lifetime is sufficient to support short-term memory. We combined in vivo recordings from granule cells (GCs), in vitro paired recordings from mossy fiber terminals and postsynaptic CA3 neurons, and “flash and freeze” electron microscopy. PTP was induced at single synapses and showed a low induction threshold adapted to sparse GC activity in vivo. PTP was mainly generated by enlargement of the readily releasable pool of synaptic vesicles, allowing multiplicative interaction with other plasticity forms. PTP was associated with an increase in the docked vesicle pool, suggesting formation of structural “pool engrams.” Absence of presynaptic activity extended the lifetime of the potentiation, enabling prolonged information storage in the hippocampal network."}],"type":"journal_article","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"8811","checksum":"4030b2be0c9625d54694a1e9fb00305e","success":1,"date_updated":"2020-11-25T11:23:02Z","date_created":"2020-11-25T11:23:02Z","access_level":"open_access","file_name":"2020_Neuron_Vandael.pdf","content_type":"application/pdf","file_size":4390833,"creator":"dernst"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"8001","intvolume":" 107","ddc":["570"],"status":"public","title":"Short-term plasticity at hippocampal mossy fiber synapses is induced by natural activity patterns and associated with vesicle pool engram formation"},{"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"ScienComp"},{"_id":"PreCl"}],"language":[{"iso":"eng"}],"doi":"10.1016/j.neuron.2020.07.006","isi":1,"quality_controlled":"1","project":[{"name":"Biophysics and circuit function of a giant cortical glumatergic synapse","call_identifier":"H2020","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","grant_number":"692692"},{"_id":"25C5A090-B435-11E9-9278-68D0E5697425","grant_number":"Z00312","call_identifier":"FWF","name":"The Wittgenstein Prize"}],"oa":1,"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png"},"external_id":{"isi":["000579698700009"],"pmid":["32763145"]},"month":"09","publication_identifier":{"issn":["0896-6273"]},"date_created":"2020-08-14T09:36:05Z","date_updated":"2023-08-22T08:30:55Z","volume":107,"author":[{"full_name":"Zhang, Xiaomin","id":"423EC9C2-F248-11E8-B48F-1D18A9856A87","first_name":"Xiaomin","last_name":"Zhang"},{"full_name":"Schlögl, Alois","orcid":"0000-0002-5621-8100","id":"45BF87EE-F248-11E8-B48F-1D18A9856A87","last_name":"Schlögl","first_name":"Alois"},{"full_name":"Jonas, Peter M","last_name":"Jonas","first_name":"Peter M","orcid":"0000-0001-5001-4804","id":"353C1B58-F248-11E8-B48F-1D18A9856A87"}],"related_material":{"link":[{"relation":"press_release","description":"News on IST Website","url":"https://ist.ac.at/en/news/the-bouncer-in-the-brain/"}]},"publication_status":"published","publisher":"Elsevier","department":[{"_id":"PeJo"},{"_id":"ScienComp"}],"acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation program (grant agreement 692692, P.J.) and the Fond zur Förderung der Wissenschaftlichen Forschung (Z 312-B27, Wittgenstein award, P.J.).

To examine the role of GCs in spatial coding, we measured excitatory postsynaptic potentials (EPSPs) and action potentials (APs) in head-fixed mice running on a linear belt. Intracellular recording from morphologically identified GCs revealed that most cells were active, but activity level varied over a wide range. Whereas only ∼5% of GCs showed spatially tuned spiking, ∼50% received spatially tuned input. Thus, the GC population broadly encodes spatial information, but only a subset relays this information to the CA3 network. Fourier analysis indicated that GCs received conjunctive place-grid-like synaptic input, suggesting code conversion in single neurons. GC firing was correlated with dendritic complexity and intrinsic excitability, but not extrinsic excitatory input or dendritic cable properties. Thus, functional maturation may control input-output transformation and spatial code conversion."}],"issue":"6","type":"journal_article"},{"citation":{"chicago":"Borges Merjane, Carolina, Olena Kim, and Peter M Jonas. “Functional Electron Microscopy (‘Flash and Freeze’) of Identified Cortical Synapses in Acute Brain Slices.” Neuron.

Electrophysiology has elucidated mechanisms of synaptic transmission, and electron microscopy (EM) has provided insight into morphological properties of synapses. Here we describe an enhanced method for functional EM (“flash and freeze”), combining optogenetic stimulation with high-pressure freezing. We demonstrate that the improved method can be applied to intact networks in acute brain slices and organotypic slice cultures from mice. As a proof of concept, we probed vesicle pool changes during synaptic transmission at the hippocampal mossy fiber-CA3 pyramidal neuron synapse. Our findings show overlap of the docked vesicle pool and the functionally defined readily releasable pool and provide evidence of fast endocytosis at this synapse. Functional EM with acute slices and slice cultures has the potential to reveal the structural and functional mechanisms of transmission in intact, genetically perturbed, and disease-affected synapses."}],"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png"},"external_id":{"isi":["000520854700008"],"pmid":["31928842"]},"oa":1,"project":[{"grant_number":"692692","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Biophysics and circuit function of a giant cortical glumatergic synapse"},{"name":"Presynaptic calcium channels distribution and impact on coupling at the hippocampal mossy fiber synapse","call_identifier":"H2020","_id":"25BAF7B2-B435-11E9-9278-68D0E5697425","grant_number":"708497"},{"_id":"25C5A090-B435-11E9-9278-68D0E5697425","grant_number":"Z00312","call_identifier":"FWF","name":"The Wittgenstein Prize"},{"name":"Zellkommunikation in Gesundheit und Krankheit","call_identifier":"FWF","grant_number":"W01205","_id":"25C3DBB6-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","isi":1,"doi":"10.1016/j.neuron.2019.12.022","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0896-6273"]},"month":"03","pmid":1,"year":"2020","acknowledgement":"This project has received funding from the European Research Council (ERC) and European Commission (EC), under the European Union’s Horizon 2020 research and innovation programme (ERC grant agreement No. 692692 and Marie Sklodowska-Curie 708497) and from Fonds zur Förderung der Wissenschaftlichen Forschung (Z 312-B27 Wittgenstein award and DK W1205-B09).
