Yet how these changes influence the neuronal computations necessary for normal brain function are not well understood. To identify cellular mechanisms underlying the maturation of synaptic integration in interneurons, we combined patch-clamp recordings of excitatory inputs in mouse cerebellar stellate cells (SCs), three-dimensional reconstruction of SC morphology with excitatory synapse location, and biophysical modeling. We found that postnatal maturation of postsynaptic strength was homogeneously reduced along the somatodendritic axis, but dendritic integration was always sublinear. However, dendritic branching increased without changes in synapse density, leading to a substantial gain in distal inputs. Thus, changes in synapse distribution, rather than dendrite cable properties, are the dominant mechanism underlying the maturation of neuronal computation. These mechanisms favor the emergence of a spatially compartmentalized two-stage integration model promoting location-dependent integration within dendritic subunits."}],"file":[{"creator":"cchlebak","file_size":13131322,"file_name":"2021_eLife_Biane.pdf","access_level":"open_access","date_updated":"2021-12-10T08:31:41Z","checksum":"c7c33c3319428d56e332e22349c50ed3","relation":"main_file","file_id":"10528","content_type":"application/pdf","success":1,"date_created":"2021-12-10T08:31:41Z"}],"article_number":"e65954","oa":1,"publication_status":"published","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":10,"file_date_updated":"2021-12-10T08:31:41Z","has_accepted_license":"1","oa_version":"Published Version","year":"2021","article_type":"original","publication_identifier":{"eissn":["2050-084X"]},"external_id":{"isi":["000715789500001"]},"scopus_import":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-14T13:12:07Z"},{"year":"2021","oa_version":"None","has_accepted_license":"1","publication_identifier":{"isbn":["9781071615218"],"eisbn":["9781071615225"]},"date_updated":"2024-03-25T23:30:16Z","user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","article_processing_charge":"No","_id":"9756","date_published":"2021-07-27T00:00:00Z","abstract":[{"text":"High-resolution visualization and quantification of membrane proteins contribute to the understanding of their functions and the roles they play in physiological and pathological conditions. Sodium dodecyl sulfate-digested freeze-fracture replica labeling (SDS-FRL) is a powerful electron microscopy method to study quantitatively the two-dimensional distribution of transmembrane proteins and their tightly associated proteins. During treatment with SDS, intracellular organelles and proteins not anchored to the replica are dissolved, whereas integral membrane proteins captured and stabilized by carbon/platinum deposition remain on the replica. Their intra- and extracellular domains become exposed on the surface of the replica, facilitating the accessibility of antibodies and, therefore, providing higher labeling efficiency than those obtained with other immunoelectron microscopy techniques. In this chapter, we describe the protocols of SDS-FRL adapted for mammalian brain samples, and optimization of the SDS treatment to increase the labeling efficiency for quantification of Cav2.1, the alpha subunit of P/Q-type voltage-dependent calcium channels utilizing deep learning algorithms.","lang":"eng"}],"publication_status":"published","volume":169,"title":"High-Resolution localization and quantitation of membrane proteins by SDS-digested freeze-fracture replica labeling (SDS-FRL)","ec_funded":1,"citation":{"ama":"Kaufmann W, Kleindienst D, Harada H, Shigemoto R.

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."}],"_id":"7878","date_published":"2020-05-13T00:00:00Z","scopus_import":"1","external_id":{"isi":["000535191600001"],"pmid":["32401196"]},"date_updated":"2023-08-21T06:26:50Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_identifier":{"eissn":["2050084X"]},"article_type":"original","has_accepted_license":"1","oa_version":"Published Version","year":"2020"},{"ddc":["570"],"doi":"10.1523/JNEUROSCI.2946-19.2020","language":[{"iso":"eng"}],"type":"journal_article","author":[{"last_name":"Wang","full_name":"Wang, Han Ying","first_name":"Han Ying"},{"last_name":"Eguchi","full_name":"Eguchi, Kohgaku","first_name":"Kohgaku","orcid":"0000-0002-6170-2546","id":"2B7846DC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Yamashita, Takayuki","first_name":"Takayuki","last_name":"Yamashita"},{"full_name":"Takahashi, Tomoyuki","first_name":"Tomoyuki","last_name":"Takahashi"}],"day":"20","title":"Frequency-dependent block of excitatory neurotransmission by isoflurane via dual presynaptic mechanisms","citation":{"mla":"Wang, Han Ying, et al. “Frequency-Dependent Block of Excitatory Neurotransmission by Isoflurane via Dual Presynaptic Mechanisms.” <i>Journal of Neuroscience</i>, vol. 40, no. 21, Society for Neuroscience, 2020, pp. 4103–15, doi:<a href=\"https://doi.org/10.1523/JNEUROSCI.2946-19.2020\">10.1523/JNEUROSCI.2946-19.2020</a>.","ieee":"H.

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."}],"file":[{"file_name":"2020_JourNeuroscience_Wang.pdf","creator":"dernst","file_size":3817360,"date_updated":"2020-07-14T12:48:05Z","access_level":"open_access","checksum":"6571607ea9036154b67cc78e848a7f7d","content_type":"application/pdf","file_id":"7912","relation":"main_file","date_created":"2020-06-02T09:12:16Z"}],"article_processing_charge":"No","issue":"21"},{"publication_identifier":{"eissn":["14220067"],"issn":["16616596"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2024-03-25T23:30:16Z","external_id":{"isi":["000579945300001"]},"scopus_import":"1","oa_version":"Published Version","year":"2020","has_accepted_license":"1","article_type":"original","oa":1,"publication_status":"published","volume":21,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2020-09-21T14:08:58Z","issue":"18","article_processing_charge":"No","_id":"8532","date_published":"2020-09-14T00:00:00Z","abstract":[{"lang":"eng","text":"The molecular anatomy of synapses defines their characteristics in transmission and plasticity.

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."}],"article_number":"6737","file":[{"file_name":"2020_JournMolecSciences_Kleindienst.pdf","creator":"dernst","file_size":5748456,"checksum":"2e4f62f3cfe945b7391fc3070e5a289f","date_updated":"2020-09-21T14:08:58Z","access_level":"open_access","content_type":"application/pdf","file_id":"8551","relation":"main_file","date_created":"2020-09-21T14:08:58Z","success":1}],"acknowledgement":"This research was funded by Austrian Academy of Sciences, DOC fellowship to D.K., European Research\r\nCouncil Advanced Grant 694539 and European Union Human Brain Project (HBP) SGA2 785907 to R.S.\r\nWe acknowledge Elena Hollergschwandtner for technical support.","related_material":{"record":[{"relation":"dissertation_contains","id":"9562","status":"public"}]},"project":[{"call_identifier":"H2020","_id":"25CA28EA-B435-11E9-9278-68D0E5697425","name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour","grant_number":"694539"},{"name":"Mechanism of formation and maintenance of input side-dependent asymmetry in the hippocampus","_id":"25D32BC0-B435-11E9-9278-68D0E5697425"},{"name":"Human Brain Project Specific Grant Agreement 2 (HBP SGA 2)","grant_number":"785907","call_identifier":"H2020","_id":"26436750-B435-11E9-9278-68D0E5697425"}],"ddc":["570"],"doi":"10.3390/ijms21186737","language":[{"iso":"eng"}],"title":"Deep learning-assisted high-throughput analysis of freeze-fracture replica images applied to glutamate receptors and calcium channels at hippocampal synapses","ec_funded":1,"citation":{"chicago":"Kleindienst, David, Jacqueline-Claire Montanaro-Punzengruber, Pradeep Bhandari, Matthew J Case, Yugo Fukazawa, and Ryuichi Shigemoto. “Deep Learning-Assisted High-Throughput Analysis of Freeze-Fracture Replica Images Applied to Glutamate Receptors and Calcium Channels at Hippocampal Synapses.” <i>International Journal of Molecular Sciences</i>.

Delayed cognitive development in humans with GluD2 gene mutations suggests extracerebellar functions of GluD2. However, extracerebellar expression of GluD2 and its relationship with that of GluD1 are poorly understood. GluD2 mRNA and protein were widely detected, with relatively high levels observed in the olfactory glomerular layer, medial prefrontal cortex, cingulate cortex, retrosplenial granular cortex, olfactory tubercle, subiculum, striatum, lateral septum, anterodorsal thalamic nucleus, and arcuate hypothalamic nucleus. These regions were also enriched for GluD1, and many individual neurons coexpressed the two GluDs. In the retrosplenial granular cortex, GluD1 and GluD2 were selectively expressed at PSD‐95‐expressing glutamatergic synapses, and their coexpression on the same synapses was shown by SDS‐digested freeze‐fracture replica labeling. Biochemically, GluD1 and GluD2 formed coimmunoprecipitable complex formation in HEK293T cells and in the cerebral cortex and hippocampus. We further estimated the relative protein amount by quantitative immunoblotting using GluA2/GluD2 and GluA2/GluD1 chimeric proteins as standards for titration of GluD1 and GluD2 antibodies. Intriguingly, the relative amount of GluD2 was almost comparable to that of GluD1 in the postsynaptic density fraction prepared from the cerebral cortex and hippocampus. In contrast, GluD2 was overwhelmingly predominant in the cerebellum. Thus, we have determined the relative extracerebellar expression of GluD1 and GluD2 at regional, neuronal, and synaptic levels. These data provide a molecular–anatomical basis for possible competitive and cooperative interactions of GluD family members at synapses in various brain regions.","lang":"eng"}],"issue":"6","article_processing_charge":"No","volume":528,"publication_status":"published"},{"publication_identifier":{"issn":["10156305"],"eissn":["17503639"]},"scopus_import":"1","external_id":{"pmid":["31729777"],"isi":["000502270900001"]},"date_updated":"2023-09-06T14:48:01Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","year":"2020","oa_version":"Published Version","has_accepted_license":"1","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":30,"file_date_updated":"2020-09-22T09:47:19Z","oa":1,"publication_status":"published","date_published":"2020-05-01T00:00:00Z","_id":"7207","abstract":[{"lang":"eng","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."}],"file":[{"file_id":"8554","relation":"main_file","content_type":"application/pdf","success":1,"date_created":"2020-09-22T09:47:19Z","creator":"dernst","file_size":4220935,"file_name":"2020_BrainPathology_MartinBelmonte.pdf","access_level":"open_access","date_updated":"2020-09-22T09:47:19Z","checksum":"549cc1b18f638a21d17a939ba5563fa9"}],"article_processing_charge":"No","issue":"3","ddc":["570"],"doi":"10.1111/bpa.12802","language":[{"iso":"eng"}],"project":[{"grant_number":"720270","name":"Human Brain Project Specific Grant Agreement 1 (HBP SGA 1)","_id":"25CBA828-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"call_identifier":"H2020","_id":"26436750-B435-11E9-9278-68D0E5697425","name":"Human Brain Project Specific Grant Agreement 2 (HBP SGA 2)","grant_number":"785907"}],"pmid":1,"type":"journal_article","author":[{"last_name":"Martín-Belmonte","first_name":"Alejandro","full_name":"Martín-Belmonte, Alejandro"},{"first_name":"Carolina","full_name":"Aguado, Carolina","last_name":"Aguado"},{"last_name":"Alfaro-Ruíz","full_name":"Alfaro-Ruíz, Rocío","first_name":"Rocío"},{"last_name":"Moreno-Martínez","first_name":"Ana Esther","full_name":"Moreno-Martínez, Ana Esther"},{"first_name":"Luis","full_name":"De La Ossa, Luis","last_name":"De La Ossa"},{"last_name":"Martínez-Hernández","full_name":"Martínez-Hernández, José","first_name":"José"},{"last_name":"Buisson","full_name":"Buisson, Alain","first_name":"Alain"},{"full_name":"Früh, Simon","first_name":"Simon","last_name":"Früh"},{"last_name":"Bettler","first_name":"Bernhard","full_name":"Bettler, Bernhard"},{"orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","full_name":"Shigemoto, Ryuichi","first_name":"Ryuichi","last_name":"Shigemoto"},{"full_name":"Fukazawa, Yugo","first_name":"Yugo","last_name":"Fukazawa"},{"first_name":"Rafael","full_name":"Luján, Rafael","last_name":"Luján"}],"day":"01","title":"Reduction in the neuronal surface of post and presynaptic GABA>B< receptors in the hippocampus in a mouse model of Alzheimer's disease","citation":{"short":"A.

In central presynaptic terminals, F-actin is expressed along the release edge and reportedly plays diverse functional roles, but whether axonal MTs extend deep into terminals and play any physiological role remains controversial. At the calyx of Held in rats of either sex, confocal and high-resolution microscopy revealed that MTs enter deep into presynaptic terminal swellings and partially colocalize with a subset of synaptic vesicles (SVs). Electrophysiological analysis demonstrated that depolymerization of MTs specifically prolonged the slow-recovery time component of EPSCs from short-term depression induced by a train of high-frequency stimulation, whereas depolymerization of F-actin specifically prolonged the fast-recovery component. In simultaneous presynaptic and postsynaptic action potential recordings, depolymerization of MTs or F-actin significantly impaired the fidelity of high-frequency neurotransmission. We conclude that MTs and F-actin differentially contribute to slow and fast SV replenishment, thereby maintaining high-frequency neurotransmission.","lang":"eng"}],"_id":"7339","date_published":"2020-01-02T00:00:00Z","external_id":{"isi":["000505167600013"],"pmid":["31767677"]},"scopus_import":"1","date_updated":"2023-08-17T14:25:23Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_identifier":{"eissn":["15292401"]},"article_type":"original","has_accepted_license":"1","year":"2020","oa_version":"Published Version","publisher":"Society for Neuroscience","isi":1,"publication":"Journal of neuroscience","quality_controlled":"1","department":[{"_id":"RySh"}],"intvolume":"        40","status":"public","page":"131-142","month":"01","date_created":"2020-01-19T23:00:38Z","pmid":1,"language":[{"iso":"eng"}],"doi":"10.1523/JNEUROSCI.1571-19.2019","ddc":["570"],"citation":{"apa":"Piriya Ananda Babu, L., Wang, H.

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"}],"file":[{"checksum":"4589234fdb12b4ad72273b311723a7b4","access_level":"open_access","date_updated":"2021-03-01T23:30:04Z","creator":"pbhandari","file_size":9646346,"file_name":"Pradeep Bhandari Thesis.pdf","embargo":"2021-02-28","date_created":"2020-02-28T08:37:53Z","title":"Localization and functional role of Cav2.3 in the medial habenula to interpeduncular nucleus pathway","file_id":"7538","relation":"main_file","content_type":"application/pdf"},{"checksum":"aa79490553ca0a5c9b6fbcd152e93928","access_level":"closed","date_updated":"2021-03-01T23:30:04Z","file_size":35252164,"creator":"pbhandari","file_name":"Pradeep Bhandari Thesis.docx","embargo_to":"open_access","date_created":"2020-02-28T08:47:14Z","title":"Localization and functional role of Cav2.3 in the medial habenula to interpeduncular nucleus pathway","file_id":"7539","relation":"source_file","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document"}],"oa":1,"publication_status":"published","file_date_updated":"2021-03-01T23:30:04Z"},{"article_type":"original","oa_version":"Published Version","has_accepted_license":"1","year":"2020","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-21T06:13:19Z","scopus_import":"1","external_id":{"pmid":["32252271"],"isi":["000535574200201"]},"publication_identifier":{"eissn":["14220067"]},"file":[{"creator":"dernst","file_size":2941197,"file_name":"2020_JournMolecSciences_Martin_Belmonte.pdf","access_level":"open_access","date_updated":"2020-07-14T12:48:01Z","checksum":"b9d2f1657d8c4a74b01a62b474d009b0","file_id":"7669","relation":"main_file","content_type":"application/pdf","date_created":"2020-04-20T11:43:18Z"}],"article_number":"2459","_id":"7664","abstract":[{"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","lang":"eng"}],"date_published":"2020-04-02T00:00:00Z","issue":"7","article_processing_charge":"No","file_date_updated":"2020-07-14T12:48:01Z","volume":21,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"publication_status":"published","oa":1,"day":"02","type":"journal_article","author":[{"first_name":"Alejandro","full_name":"Martín-Belmonte, Alejandro","last_name":"Martín-Belmonte"},{"first_name":"Carolina","full_name":"Aguado, Carolina","last_name":"Aguado"},{"last_name":"Alfaro-Ruíz","first_name":"Rocío","full_name":"Alfaro-Ruíz, Rocío"},{"last_name":"Moreno-Martínez","full_name":"Moreno-Martínez, Ana Esther","first_name":"Ana Esther"},{"last_name":"De La Ossa","first_name":"Luis","full_name":"De La Ossa, Luis"},{"full_name":"Martínez-Hernández, José","first_name":"José","last_name":"Martínez-Hernández"},{"full_name":"Buisson, Alain","first_name":"Alain","last_name":"Buisson"},{"last_name":"Shigemoto","first_name":"Ryuichi","full_name":"Shigemoto, Ryuichi","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Fukazawa, Yugo","first_name":"Yugo","last_name":"Fukazawa"},{"first_name":"Rafael","full_name":"Luján, Rafael","last_name":"Luján"}],"citation":{"ama":"Martín-Belmonte A, Aguado C, Alfaro-Ruíz R, et al.

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."}]},{"citation":{"mla":"Byczkowicz, Niklas, et al. “HCN Channel-Mediated Neuromodulation Can Control Action Potential Velocity and Fidelity in Central Axons.” <i>ELife</i>, vol. 8, e42766, eLife Sciences Publications, 2019, doi:<a href=\"https://doi.org/10.7554/eLife.42766\">10.7554/eLife.42766</a>.","chicago":"Byczkowicz, Niklas, Abdelmoneim Eshra, Jacqueline-Claire Montanaro-Punzengruber, Andrea Trevisiol, Johannes Hirrlinger, Maarten Hp Kole, Ryuichi Shigemoto, and Stefan Hallermann. “HCN Channel-Mediated Neuromodulation Can Control Action Potential Velocity and Fidelity in Central Axons.” <i>ELife</i>. eLife Sciences Publications, 2019. <a href=\"https://doi.org/10.7554/eLife.42766\">https://doi.org/10.7554/eLife.42766</a>.","ieee":"N.

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.","lang":"eng"}],"publication_status":"published","oa":1,"file_date_updated":"2020-07-14T12:47:42Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":8},{"external_id":{"pmid":["31543297"],"isi":["000497963500017"]},"scopus_import":"1","date_updated":"2023-08-30T07:28:22Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_identifier":{"issn":["0896-6273"]},"article_type":"original","year":"2019","oa_version":"Published Version","has_accepted_license":"1","publication_status":"published","oa":1,"main_file_link":[{"url":"https://doi.org/10.1016/j.neuron.2019.08.013","open_access":"1"}],"volume":104,"article_processing_charge":"No","issue":"4","_id":"7099","date_published":"2019-11-20T00:00:00Z","pmid":1,"acknowledgement":"The authors thank Gabi Schmid for excellent technical support.

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.","lang":"eng"}],"issue":"12","article_processing_charge":"No","date_updated":"2023-09-06T14:34:36Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","external_id":{"isi":["000507466100054"],"pmid":["31585509"]},"scopus_import":"1","publication_identifier":{"eissn":["15306860"]},"article_type":"original","oa_version":"Submitted Version","year":"2019","has_accepted_license":"1"},{"publication_status":"published","oa":1,"file_date_updated":"2020-07-14T12:47:57Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":22,"article_processing_charge":"No","issue":"12","file":[{"file_name":"2019_iScience_Tabata.pdf","file_size":7197776,"creator":"dernst","checksum":"f3e90056a49f09b205b1c4f8c739ffd1","date_updated":"2020-07-14T12:47:57Z","access_level":"open_access","content_type":"application/pdf","file_id":"7448","relation":"main_file","date_created":"2020-02-04T10:48:36Z"}],"_id":"7391","date_published":"2019-12-20T00:00:00Z","abstract":[{"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.","lang":"eng"}],"scopus_import":"1","external_id":{"pmid":["31786521"],"isi":[":000504652000020"]},"date_updated":"2024-03-25T23:30:07Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publication_identifier":{"issn":["2589-0042"]},"article_type":"original","oa_version":"Published Version","has_accepted_license":"1","year":"2019","publisher":"Elsevier","publication":"iScience","quality_controlled":"1","department":[{"_id":"RySh"}],"intvolume":"        22","status":"public","page":"256-268","month":"12","date_created":"2020-01-29T15:56:56Z","pmid":1,"project":[{"call_identifier":"H2020","_id":"25CA28EA-B435-11E9-9278-68D0E5697425","grant_number":"694539","name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour"},{"name":"Human Brain Project Specific Grant Agreement 1 (HBP SGA 1)","grant_number":"720270","_id":"25CBA828-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"related_material":{"record":[{"relation":"dissertation_contains","id":"11393","status":"public"}]},"language":[{"iso":"eng"}],"doi":"10.1016/j.isci.2019.11.025","ddc":["570"],"citation":{"chicago":"Tabata, Shigekazu, Marijo Jevtic, Nobutaka Kurashige, Hirokazu Fuchida, Munetsugu Kido, Kazushi Tani, Naoki Zenmyo, et al. “Electron Microscopic Detection of Single Membrane Proteins by a Specific Chemical Labeling.” <i>IScience</i>.

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.","lang":"eng"}],"article_processing_charge":"No","issue":"8","file_date_updated":"2020-07-14T12:47:57Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","image":"/images/cc_by_nc_sa.png","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","short":"CC BY-NC-SA (4.0)"},"volume":151,"publication_status":"published","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","oa":1,"article_type":"original","year":"2019","oa_version":"Published Version","has_accepted_license":"1","scopus_import":"1","external_id":{"pmid":["31270129"],"isi":["000478792500008"]},"date_updated":"2023-09-07T14:52:23Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publication_identifier":{"issn":["0022-1295"],"eissn":["1540-7748"]},"month":"07","date_created":"2020-01-29T16:06:29Z","page":"1035-1050","publication":"The Journal of General Physiology","department":[{"_id":"RySh"}],"quality_controlled":"1","intvolume":"       151","status":"public","publisher":"Rockefeller University Press","isi":1,"day":"03","author":[{"full_name":"Erdem, Fatma Asli","first_name":"Fatma Asli","last_name":"Erdem"},{"full_name":"Ilic, Marija","first_name":"Marija","last_name":"Ilic"},{"last_name":"Koppensteiner","full_name":"Koppensteiner, Peter","first_name":"Peter","id":"3B8B25A8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3509-1948"},{"last_name":"Gołacki","full_name":"Gołacki, Jakub","first_name":"Jakub"},{"first_name":"Gert","full_name":"Lubec, Gert","last_name":"Lubec"},{"full_name":"Freissmuth, Michael","first_name":"Michael","last_name":"Freissmuth"},{"last_name":"Sandtner","full_name":"Sandtner, Walter","first_name":"Walter"}],"type":"journal_article","citation":{"chicago":"Erdem, Fatma Asli, Marija Ilic, Peter Koppensteiner, Jakub Gołacki, Gert Lubec, Michael Freissmuth, and Walter Sandtner. “A Comparison of the Transport Kinetics of Glycine Transporter 1 and Glycine Transporter 2.” <i>The Journal of General Physiology</i>.

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."}],"date_published":"2018-12-01T00:00:00Z"},{"article_processing_charge":"No","issue":"6","_id":"705","date_published":"2018-06-01T00:00:00Z","abstract":[{"lang":"eng","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."}],"publication_status":"published","volume":55,"year":"2018","oa_version":"None","publist_id":"6991","external_id":{"isi":["000431991500025"]},"scopus_import":"1","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","date_updated":"2023-09-19T09:58:11Z","page":"4857 – 4869","date_created":"2018-12-11T11:48:02Z","month":"06","isi":1,"publisher":"Springer","status":"public","intvolume":"        55","publication":"Molecular Neurobiology","quality_controlled":"1","department":[{"_id":"RySh"}],"title":"Super resolution microscopical localization of dopamine receptors 1 and 2 in rat hippocampal synaptosomes","citation":{"ama":"Miklosi A, Del Favero G, Bulat T, et al.
