Although the process of platelet formation by fragmenting megakaryocytes (MKs; thrombopoiesis) has been extensively studied, the cellular and molecular mechanisms required to constantly replenish the pool of MKs by their progenitor cells (megakaryopoiesis) remains unclear3,4. Here we use intravital imaging to track the cellular dynamics of megakaryopoiesis over days. We identify plasmacytoid dendritic cells (pDCs) as homeostatic sensors that monitor the bone marrow for apoptotic MKs and deliver IFNα to the MK niche triggering local on-demand proliferation and maturation of MK progenitors. This pDC-dependent feedback loop is crucial for MK and platelet homeostasis at steady state and under stress. pDCs are best known for their ability to function as vigilant detectors of viral infection5. We show that virus-induced activation of pDCs interferes with their function as homeostatic sensors of megakaryopoiesis. Consequently, activation of pDCs by SARS-CoV-2 leads to excessive megakaryopoiesis. Together, we identify a pDC-dependent homeostatic circuit that involves innate immune sensing and demand-adapted release of inflammatory mediators to maintain homeostasis of the megakaryocytic lineage.","lang":"eng"}],"scopus_import":"1","ec_funded":1,"status":"public","page":"645-653","isi":1,"date_updated":"2025-09-08T08:14:25Z","publication":"Nature","file_date_updated":"2024-07-22T06:16:11Z"},{"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"PreCl"}],"isi":1,"date_updated":"2026-04-16T12:20:34Z","publication":"PLoS Biology","file_date_updated":"2024-12-03T08:56:53Z","scopus_import":"1","DOAJ_listed":"1","ec_funded":1,"issue":"11","status":"public","has_accepted_license":"1","citation":{"chicago":"Kim, Olena, Yuji Okamoto, Walter Kaufmann, Nils Brose, Ryuichi Shigemoto, and Peter M Jonas. “Presynaptic CAMP-PKA-Mediated Potentiation Induces Reconfiguration of Synaptic Vesicle Pools and Channel-Vesicle Coupling at Hippocampal Mossy Fiber Boutons.” <i>PLoS Biology</i>.

However, direct evidence for this hypothesis is lacking. To test this conjecture, we combined chemical potentiation, functional analysis by paired pre-postsynaptic recordings, and structural analysis by electron microscopy (EM) and freeze-fracture replica labeling (FRL) at the rodent hippocampal mossy fiber synapse, a key synapse in the trisynaptic circuit of the hippocampus. Biophysical analysis of synaptic transmission revealed that forskolin-induced chemical potentiation increased the readily releasable vesicle pool size and vesicular release probability by 146% and 49%, respectively. Structural analysis of mossy fiber synapses by EM and FRL demonstrated an increase in the number of vesicles close to the plasma membrane and the number of clusters of the priming protein Munc13-1, indicating an increase in the number of both docked and primed vesicles. Furthermore, FRL analysis revealed a significant reduction of the distance between Munc13-1 and CaV2.1 Ca2+ channels, suggesting reconfiguration of the channel-vesicle coupling nanotopography. Our results indicate that presynaptic plasticity is associated with structural reorganization of active zones. We propose that changes in potential nanoscopic organization at synaptic vesicle release sites may be correlates of learning and memory at a plastic central synapse.","lang":"eng"}],"language":[{"iso":"eng"}],"external_id":{"isi":["001358568700003"],"pmid":["39556620"]},"date_published":"2024-11-18T00:00:00Z","APC_amount":"6248,82 EUR","OA_place":"publisher","year":"2024","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","ddc":["570"],"article_number":"e3002879","intvolume":"        22","project":[{"grant_number":"692692","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Biophysics and circuit function of a giant cortical glutamatergic synapse"},{"name":"Synaptic communication in neuronal microcircuits","grant_number":"Z00312","_id":"25C5A090-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"name":"Mechanisms of GABA release in hippocampal circuits","_id":"bd88be38-d553-11ed-ba76-81d5a70a6ef5","grant_number":"P36232"},{"grant_number":"I06166","_id":"b1b85715-d554-11ed-a5ad-84a07fc9f18e","name":"Structural & functional basis of presynaptic plasticity"},{"grant_number":"W01205","_id":"25C3DBB6-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Zellkommunikation in Gesundheit und Krankheit"},{"call_identifier":"FWF","_id":"3AC91DDA-15DF-11EA-824D-93A3E7B544D1","name":"FWF Open Access Fund"}],"article_type":"original","department":[{"_id":"PeJo"},{"_id":"EM-Fac"},{"_id":"RySh"}],"month":"11","author":[{"full_name":"Kim, Olena","last_name":"Kim","orcid":"0000-0003-2344-1039","id":"3F8ABDDA-F248-11E8-B48F-1D18A9856A87","first_name":"Olena"},{"full_name":"Okamoto, Yuji","last_name":"Okamoto","orcid":"0000-0003-0408-6094","first_name":"Yuji","id":"3337E116-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Kaufmann, Walter","last_name":"Kaufmann","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","first_name":"Walter"},{"first_name":"Nils","full_name":"Brose, Nils","last_name":"Brose"},{"last_name":"Shigemoto","full_name":"Shigemoto, Ryuichi","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","first_name":"Ryuichi"},{"last_name":"Jonas","full_name":"Jonas, Peter M","first_name":"Peter M","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5001-4804"}],"volume":22,"acknowledgement":"We thank Carolina Borges-Merjane, Jing-Jing Chen, Katharina Lichter, and Samuel Young for critically reading the manuscript; the Electron Microscopy Facility of ISTA, in particular Vanessa Zheden, for extensive support, advice, and experimental assistance; the Preclinical Facility of ISTA, in particular Victoria Wimmer and Michael Schunn, for experimental assistance; Florian Marr and Christina Altmutter for technical support; Alois Schlögl for help with analysis; and Eleftheria Kralli-Beller for manuscript editing.

However, the coupling nanotopography at many synapses remains unknown, and it is unclear how it changes during development. To address these questions, we examined coupling at the cerebellar inhibitory basket cell (BC)-Purkinje cell (PC) synapse. Biophysical analysis of transmission by paired recording and intracellular pipette perfusion revealed that the effects of exogenous Ca2+ chelators decreased during development, despite constant reliance of release on P/Q-type Ca2+ channels. Structural analysis by freeze-fracture replica labeling (FRL) and transmission electron microscopy (EM) indicated that presynaptic P/Q-type Ca2+ channels formed nanoclusters throughout development, whereas docked vesicles were only clustered at later developmental stages. Modeling suggested a developmental transformation from a more random to a more clustered coupling nanotopography. Thus, presynaptic signaling developmentally approaches a point-to-point configuration, optimizing speed, reliability, and energy efficiency of synaptic transmission.","lang":"eng"}],"quality_controlled":"1","type":"journal_article","ec_funded":1,"issue":"5","scopus_import":"1","PlanS_conform":"1","page":"755-771.e9","status":"public","date_updated":"2026-04-27T22:30:23Z","publication":"Neuron","isi":1,"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"PreCl"},{"_id":"M-Shop"}],"file_date_updated":"2025-04-23T14:02:08Z","title":"Developmental transformation of Ca2+ channel-vesicle nanotopography at a central GABAergic synapse","date_created":"2024-01-21T23:00:56Z","OA_type":"hybrid","oa_version":"Published Version","publication_identifier":{"eissn":["1097-4199"],"issn":["0896-6273"]},"file":[{"checksum":"30098b4f0209556ddfb3540a23d07ca5","file_name":"2024_Neuron_Chen.pdf","file_id":"19614","creator":"dernst","date_updated":"2025-04-23T14:02:08Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"date_created":"2025-04-23T14:02:08Z","file_size":8192355}],"publication_status":"published","related_material":{"link":[{"relation":"press_release","description":"News on ISTA Website","url":"https://ista.ac.at/en/news/synapses-brought-to-the-point/"}],"record":[{"relation":"dissertation_contains","status":"public","id":"15101"}]},"pmid":1,"article_processing_charge":"Yes (via OA deal)","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"corr_author":"1","publisher":"Elsevier","author":[{"full_name":"Chen, JingJing","last_name":"Chen","first_name":"JingJing","id":"2C4E65C8-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0001-9735-5315","first_name":"Walter","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","full_name":"Kaufmann, Walter","last_name":"Kaufmann"},{"first_name":"Chong","id":"3DFD581A-F248-11E8-B48F-1D18A9856A87","full_name":"Chen, Chong","last_name":"Chen"},{"last_name":"Arai","full_name":"Arai, Itaru","first_name":"Itaru","id":"32A73F6C-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Kim, Olena","last_name":"Kim","first_name":"Olena","id":"3F8ABDDA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2344-1039"},{"full_name":"Shigemoto, Ryuichi","last_name":"Shigemoto","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","first_name":"Ryuichi","orcid":"0000-0001-8761-9444"},{"first_name":"Peter M","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5001-4804","last_name":"Jonas","full_name":"Jonas, Peter M"}],"volume":112,"month":"03","department":[{"_id":"PeJo"},{"_id":"EM-Fac"},{"_id":"RySh"}],"project":[{"grant_number":"692692","call_identifier":"H2020","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","name":"Biophysics and circuit function of a giant cortical glutamatergic synapse"},{"grant_number":"Z00312","call_identifier":"FWF","_id":"25C5A090-B435-11E9-9278-68D0E5697425","name":"Synaptic communication in neuronal microcircuits"},{"name":"Mechanisms of GABA release in hippocampal circuits","_id":"bd88be38-d553-11ed-ba76-81d5a70a6ef5","grant_number":"P36232"},{"_id":"26B66A3E-B435-11E9-9278-68D0E5697425","grant_number":"25383","name":"Development of nanodomain coupling between Ca2+ channels and release sensors at a central inhibitory synapse"}],"article_type":"original","oa":1,"doi":"10.1016/j.neuron.2023.12.002","acknowledgement":"We thank Drs.

Therefore, it is critical to study biological structures in 3D and at high resolution to gain insights into their physiological functions. Electron microscopy of metal replicas of unroofed cells and isolated organelles has been a key technique to visualize intracellular structures at nanometer resolution. However, many of these methods require specialized equipment and personnel to complete them. Here, we present novel accessible methods to analyze biological structures in unroofed cells and biochemically isolated organelles in 3D and at nanometer resolution, focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential trafficking organelles, their detailed structural information is lacking due to their poor preservation when observed via classical electron microscopy protocols experiments. First, we establish a method to visualize CCVs in unroofed cells using scanning transmission electron microscopy tomography, providing sufficient resolution to define the clathrin coat arrangements. Critically, the samples are prepared directly on electron microscopy grids, removing the requirement to use extremely corrosive acids, thereby enabling the use of this method in any electron microscopy lab. Secondly, we demonstrate that this standardized sample preparation allows the direct comparison of isolated CCV samples with those visualized in cells. Finally, to facilitate the high-throughput and robust screening of metal replicated samples, we provide a deep learning analysis method to screen the “pseudo 3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes accessible ways to examine the 3D structure of biological samples and provide novel insights into the structure of plant CCVs.","lang":"eng"}],"_id":"12239","language":[{"iso":"eng"}],"citation":{"ama":"Johnson AJ, Kaufmann W, Sommer CM, et al.

This diversity of functions is partially provided by multiple monomeric and multimeric clathrin adaptor complexes that provide compartment and cargo selectivity. The adaptor-protein assembly polypeptide-1 (AP-1) complex operates as part of the secretory pathway at the trans-Golgi network (TGN), while the AP-2 complex and the TPLATE complex jointly operate at the plasma membrane to execute clathrin-mediated endocytosis. Key to our further understanding of clathrin-mediated trafficking in plants will be the comprehensive identification and characterization of the network of evolutionarily conserved and plant-specific core and accessory machinery involved in the formation and targeting of CCVs. To facilitate these studies, we have analyzed the proteome of enriched TGN/early endosome-derived and endocytic CCVs isolated from dividing and expanding suspension-cultured Arabidopsis (Arabidopsis thaliana) cells. Tandem mass spectrometry analysis results were validated by differential chemical labeling experiments to identify proteins co-enriching with CCVs. Proteins enriched in CCVs included previously characterized CCV components and cargos such as the vacuolar sorting receptors in addition to conserved and plant-specific components whose function in clathrin-mediated trafficking has not been previously defined. Notably, in addition to AP-1 and AP-2, all subunits of the AP-4 complex, but not AP-3 or AP-5, were found to be in high abundance in the CCV proteome. The association of AP-4 with suspension-cultured Arabidopsis CCVs is further supported via additional biochemical data.","lang":"eng"}],"external_id":{"isi":["000767438800001"],"pmid":["35218346"]},"day":"01","citation":{"apa":"Dahhan, D., Reynolds, G., Cárdenas, J., Eeckhout, D., Johnson, A.

Immunological challenge causes LNs to increase more than tenfold in size within a few days. Here, we characterized the biomechanics of LN swelling on the cellular and organ scale. We identified lymphocyte trapping by influx and proliferation as drivers of an outward pressure force, causing fibroblastic reticular cells of the T-zone (TRCs) and their associated conduits to stretch. After an initial phase of relaxation, TRCs sensed the resulting strain through cell matrix adhesions, which coordinated local growth and remodeling of the stromal network. While the expanded TRC network readopted its typical configuration, a massive fibrotic reaction of the organ capsule set in and countered further organ expansion. Thus, different fibroblast populations mechanically control LN swelling in a multitier fashion.","lang":"eng"}],"external_id":{"pmid":["35817845"],"isi":["000822975900002"]},"has_accepted_license":"1","day":"11","citation":{"ieee":"F.

The level of cortical tension outside of the cell–cell contact, when pulling at the contact edge, scales with the total size to which a cell–cell contact can grow [J.-L. Maître et al., Science 338, 253–256 (2012)]. Here, we show in zebrafish primary germ-layer progenitor cells that this monotonic relationship only applies to a narrow range of cortical tension increase and that above a critical threshold, contact size inversely scales with cortical tension. This switch from cortical tension increasing to decreasing progenitor cell–cell contact size is caused by cortical tension promoting E-cadherin anchoring to the actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin at the contact. After tension-mediated E-cadherin stabilization at the contact exceeds a critical threshold level, the rate by which the contact expands in response to pulling forces from the cortex sharply drops, leading to smaller contacts at physiologically relevant timescales of contact formation. Thus, the activity of cortical tension in expanding cell–cell contact size is limited by tension-stabilizing E-cadherin–actin complexes at the contact."}],"language":[{"iso":"eng"}],"scopus_import":"1","issue":"8","ec_funded":1,"status":"public","isi":1,"acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"PreCl"}],"publication":"Proceedings of the National Academy of Sciences of the United States of America","date_updated":"2026-04-02T12:54:56Z","file_date_updated":"2022-02-21T08:45:11Z"},{"year":"2022","ddc":["580"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":"       609","date_published":"2022-09-15T00:00:00Z","type":"journal_article","quality_controlled":"1","abstract":[{"lang":"eng","text":"The phytohormone auxin triggers transcriptional reprogramming through a well-characterized perception machinery in the nucleus. By contrast, mechanisms that underlie fast effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required for the auxin-induced ultrafast global phospho-response and for downstream processes that include the activation of H+-ATPase and accelerated cytoplasmic streaming. abp1 and tmk mutants cannot establish auxin-transporting channels and show defective auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that lacks the capacity to bind auxin is unable to complement these defects in abp1 mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface signalling, which mediates the global phospho-response and auxin canalization."}],"_id":"12291","language":[{"iso":"eng"}],"external_id":{"pmid":["36071161"],"isi":["000851357500002"]},"has_accepted_license":"1","citation":{"apa":"Friml, J., Gallei, M.

Here, we show that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness requires neither force sensing via the nucleus nor adhesive interactions with a substrate. Upon global compression of the cell body as well as local indentation of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into dot-like structures, providing activation platforms for Arp2/3 nucleated actin patches. These patches locally push against the external load, which can be obstructing collagen fibers or other cells, and thereby create space to facilitate forward locomotion. We show in vitro and in vivo that this WASp function is rate limiting for ameboid leukocyte migration in dense but not in loose environments and is required for trafficking through diverse tissues such as skin and lymph nodes.","lang":"eng"}],"_id":"10703","language":[{"iso":"eng"}],"external_id":{"pmid":["34919802"],"isi":["000768933800005"]},"pmid":1,"related_material":{"record":[{"status":"public","id":"20149","relation":"dissertation_contains"},{"status":"public","id":"12726","relation":"dissertation_contains"},{"status":"public","id":"14530","relation":"dissertation_contains"},{"relation":"dissertation_contains","status":"public","id":"12401"}]},"publisher":"Cell Press","corr_author":"1","tmp":{"image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","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"},"article_processing_charge":"No","project":[{"_id":"260AA4E2-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"747687","name":"Mechanical Adaptation of Lamellipodial Actin Networks in Migrating Cells"},{"name":"Cellular Navigation Along Spatial Gradients","grant_number":"724373","_id":"25FE9508-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"article_type":"original","department":[{"_id":"MiSi"},{"_id":"EM-Fac"},{"_id":"NanoFab"},{"_id":"BjHo"}],"month":"01","volume":57,"author":[{"full_name":"Gaertner, Florian","last_name":"Gaertner","first_name":"Florian"},{"full_name":"Dos Reis Rodrigues, Patricia","last_name":"Dos Reis Rodrigues","orcid":"0000-0003-1681-508X","first_name":"Patricia","id":"26E95904-5160-11E9-9C0B-C5B0DC97E90F"},{"first_name":"Ingrid","id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","full_name":"De Vries, Ingrid","last_name":"De Vries"},{"id":"4167FE56-F248-11E8-B48F-1D18A9856A87","first_name":"Miroslav","orcid":"0000-0002-6625-3348","last_name":"Hons","full_name":"Hons, Miroslav"},{"first_name":"Juan","last_name":"Aguilera","full_name":"Aguilera, Juan"},{"full_name":"Riedl, Michael","last_name":"Riedl","orcid":"0000-0003-4844-6311","id":"3BE60946-F248-11E8-B48F-1D18A9856A87","first_name":"Michael"},{"last_name":"Leithner","full_name":"Leithner, Alexander F","first_name":"Alexander F","id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1073-744X"},{"orcid":"0000-0003-1671-393X","first_name":"Saren","id":"4323B49C-F248-11E8-B48F-1D18A9856A87","last_name":"Tasciyan","full_name":"Tasciyan, Saren"},{"orcid":"0000-0002-2187-6656","first_name":"Aglaja","id":"31DAC7B6-F248-11E8-B48F-1D18A9856A87","last_name":"Kopf","full_name":"Kopf, Aglaja"},{"orcid":"0000-0001-5145-4609","first_name":"Jack","id":"4515C308-F248-11E8-B48F-1D18A9856A87","full_name":"Merrin, Jack","last_name":"Merrin"},{"full_name":"Zheden, Vanessa","last_name":"Zheden","id":"39C5A68A-F248-11E8-B48F-1D18A9856A87","first_name":"Vanessa","orcid":"0000-0002-9438-4783"},{"full_name":"Kaufmann, Walter","last_name":"Kaufmann","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","first_name":"Walter"},{"orcid":"0000-0001-9843-3522","first_name":"Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","full_name":"Hauschild, Robert","last_name":"Hauschild"},{"orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","first_name":"Michael K","full_name":"Sixt, Michael K","last_name":"Sixt"}],"acknowledgement":"We thank N.

Experimental data suggest that microglial TLR4 mediates the uptake and clearance of α-synuclein also termed synucleinophagy. The accumulation of misfolded α-synuclein throughout the brain is central to Parkinson's disease (PD). The distribution and progression of the pathology is often attributed to the propagation of α-synuclein. Here, we apply a classical α-synuclein propagation model of prodromal PD in wild type and TLR4 deficient mice to study the role of TLR4 in the progression of the disease. Our data suggest that TLR4 deficiency facilitates the α-synuclein seed spreading associated with reduced lysosomal activity of microglia. Three months after seed inoculation, more pronounced proteinase K-resistant α-synuclein inclusion pathology is observed in mice with TLR4 deficiency. The facilitated propagation of α-synuclein is associated with early loss of dopamine transporter (DAT) signal in the striatum and loss of dopaminergic neurons in substantia nigra pars compacta of TLR4 deficient mice. These new results support TLR4 signaling as a putative target for disease modification to slow the progression of PD and related disorders.","lang":"eng"}],"language":[{"iso":"eng"}],"external_id":{"isi":["000701142900012"],"pmid":["34530328"]},"type":"journal_article","quality_controlled":"1","scopus_import":"1","page":"59-65","status":"public","date_updated":"2023-08-17T06:36:01Z","publication":"Parkinsonism & Related Disorders","isi":1,"file_date_updated":"2022-01-10T13:41:40Z"},{"status":"public","page":"351-369","issue":"1","ec_funded":1,"scopus_import":"1","file_date_updated":"2021-02-04T09:44:17Z","publication":"New Phytologist","date_updated":"2025-06-12T06:32:24Z","acknowledged_ssus":[{"_id":"Bio"}],"isi":1,"intvolume":"       229","year":"2021","ddc":["580"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2021-01-01T00:00:00Z","_id":"8582","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Cell and tissue polarization is fundamental for plant growth and morphogenesis.

Here we show that α2δ subunits are essential for the formation and organization of glutamatergic synapses. Using a cellular α2δ subunit triple-knockout/knockdown model, we demonstrate a failure in presynaptic differentiation evidenced by defective presynaptic calcium channel clustering and calcium influx, smaller presynaptic active zones, and a strongly reduced accumulation of presynaptic vesicle-associated proteins (synapsin and vGLUT). The presynaptic defect is associated with the downscaling of postsynaptic AMPA receptors and the postsynaptic density. The role of α2δ isoforms as synaptic organizers is highly redundant, as each individual α2δ isoform can rescue presynaptic calcium channel trafficking and expression of synaptic proteins. Moreover, α2δ-2 and α2δ-3 with mutated metal ion-dependent adhesion sites can fully rescue presynaptic synapsin expression but only partially calcium channel trafficking, suggesting that the regulatory role of α2δ subunits is independent from its role as a calcium channel subunit. Our findings influence the current view on excitatory synapse formation. First, our study suggests that postsynaptic differentiation is secondary to presynaptic differentiation. Second, the dependence of presynaptic differentiation on α2δ implicates α2δ subunits as potential nucleation points for the organization of synapses. Finally, our results suggest that α2δ subunits act as transsynaptic organizers of glutamatergic synapses, thereby aligning the synaptic active zone with the postsynaptic density."}],"language":[{"iso":"eng"}],"citation":{"ista":"Schöpf CL, Ablinger C, Geisler SM, Stanika RI, Campiglio M, Kaufmann W, Nimmervoll B, Schlick B, Brockhaus J, Missler M, Shigemoto R, Obermair GJ. 2021.

During endocytosis, an area of flat membrane is remodeled by proteins to create a spherical vesicle against intracellular forces. The protein machinery which mediates this membrane bending in plants is unknown. However, it is known that plant endocytosis is actin independent, thus indicating that plants utilize a unique mechanism to mediate membrane bending against high-turgor pressure compared to other model systems. Here, we investigate the TPLATE complex, a plant-specific endocytosis protein complex. It has been thought to function as a classical adaptor functioning underneath the clathrin coat. However, by using biochemical and advanced live microscopy approaches, we found that TPLATE is peripherally associated with clathrin-coated vesicles and localizes at the rim of endocytosis events. As this localization is more fitting to the protein machinery involved in membrane bending during endocytosis, we examined cells in which the TPLATE complex was disrupted and found that the clathrin structures present as flat patches. This suggests a requirement of the TPLATE complex for membrane bending during plant clathrin–mediated endocytosis. Next, we used in vitro biophysical assays to confirm that the TPLATE complex possesses protein domains with intrinsic membrane remodeling activity. These results redefine the role of the TPLATE complex and implicate it as a key component of the evolutionarily distinct plant endocytosis mechanism, which mediates endocytic membrane bending against the high-turgor pressure in plant cells."}],"_id":"9887","language":[{"iso":"eng"}],"external_id":{"pmid":["34907016"],"isi":["000736417600043"]},"has_accepted_license":"1","citation":{"apa":"Johnson, A.

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"}],"language":[{"iso":"eng"}],"date_published":"2021-07-27T00:00:00Z","ddc":["573"],"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","year":"2021","intvolume":"       169","date_updated":"2026-04-27T22:30:38Z","publication":" Receptor and Ion Channel Detection in the Brain","scopus_import":"1","ec_funded":1,"status":"public","page":"267-283"},{"file":[{"checksum":"2052daa4be5019534f3a42f200a09f32","file_name":"2020_eLife_Narasimhan.pdf","file_id":"7494","relation":"main_file","date_updated":"2020-07-14T12:47:59Z","creator":"dernst","access_level":"open_access","content_type":"application/pdf","file_size":7247468,"date_created":"2020-02-18T07:21:16Z"}],"publication_status":"published","title":"Evolutionarily unique mechanistic framework of clathrin-mediated endocytosis in plants","date_created":"2020-02-16T23:00:50Z","oa_version":"Published Version","publication_identifier":{"eissn":["2050-084X"]},"author":[{"orcid":"0000-0002-8600-0671","first_name":"Madhumitha","id":"44BF24D0-F248-11E8-B48F-1D18A9856A87","last_name":"Narasimhan","full_name":"Narasimhan, Madhumitha"},{"orcid":"0000-0002-2739-8843","first_name":"Alexander J","id":"46A62C3A-F248-11E8-B48F-1D18A9856A87","full_name":"Johnson, Alexander J","last_name":"Johnson"},{"last_name":"Prizak","full_name":"Prizak, Roshan","id":"4456104E-F248-11E8-B48F-1D18A9856A87","first_name":"Roshan"},{"id":"3F99E422-F248-11E8-B48F-1D18A9856A87","first_name":"Walter","orcid":"0000-0001-9735-5315","last_name":"Kaufmann","full_name":"Kaufmann, Walter"},{"full_name":"Tan, Shutang","last_name":"Tan","id":"2DE75584-F248-11E8-B48F-1D18A9856A87","first_name":"Shutang","orcid":"0000-0002-0471-8285"},{"last_name":"Casillas Perez","full_name":"Casillas Perez, Barbara E","id":"351ED2AA-F248-11E8-B48F-1D18A9856A87","first_name":"Barbara E"},{"orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jiří","last_name":"Friml","full_name":"Friml, Jiří"}],"volume":9,"department":[{"_id":"JiFr"},{"_id":"GaTk"},{"_id":"EM-Fac"},{"_id":"SyCr"}],"month":"01","project":[{"grant_number":"742985","_id":"261099A6-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Tracing Evolution of Auxin Transport and Polarity in Plants"},{"name":"Molecular mechanisms of endocytic cargo recognition in plants","grant_number":"I03630","call_identifier":"FWF","_id":"26538374-B435-11E9-9278-68D0E5697425"}],"article_type":"original","oa":1,"doi":"10.7554/eLife.52067","pmid":1,"article_processing_charge":"No","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"publisher":"eLife Sciences Publications","day":"23","citation":{"mla":"Narasimhan, Madhumitha, et al. “Evolutionarily Unique Mechanistic Framework of Clathrin-Mediated Endocytosis in Plants.” <i>ELife</i>, vol. 9, e52067, eLife Sciences Publications, 2020, doi:<a href=\"https://doi.org/10.7554/eLife.52067\">10.7554/eLife.52067</a>.","short":"M.

It has been assumed to operate in an evolutionary conserved manner as in yeast and animals. Here we report characterisation of ultrastructure, dynamics and mechanisms of plant CME as allowed by our advancement in electron microscopy and quantitative live imaging techniques. Arabidopsis CME appears to follow the constant curvature model and the bona fide CME population generates vesicles of a predominantly hexagonal-basket type; larger and with faster kinetics than in other models. Contrary to the existing paradigm, actin is dispensable for CME events at the plasma membrane but plays a unique role in collecting endocytic vesicles, sorting of internalised cargos and directional endosome movement that itself actively promote CME events. Internalized vesicles display a strongly delayed and sequential uncoating. These unique features highlight the independent evolution of the plant CME mechanism during the autonomous rise of multicellularity in eukaryotes.","lang":"eng"}],"quality_controlled":"1","type":"journal_article","date_published":"2020-01-23T00:00:00Z","intvolume":"         9","article_number":"e52067","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","ddc":["570","580"],"year":"2020","publication":"eLife","date_updated":"2025-04-14T07:45:03Z","isi":1,"acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"},{"_id":"EM-Fac"}],"file_date_updated":"2020-07-14T12:47:59Z","ec_funded":1,"scopus_import":"1","status":"public"},{"date_updated":"2026-04-27T22:30:29Z","publication":"Journal of Cell Science","isi":1,"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"Bio"}],"file_date_updated":"2021-08-08T22:30:03Z","issue":"15","ec_funded":1,"scopus_import":"1","status":"public","citation":{"chicago":"Johnson, Alexander J, Nataliia Gnyliukh, Walter Kaufmann, Madhumitha Narasimhan, G Vert, SY Bednarek, and Jiří Friml. “Experimental Toolbox for Quantitative Evaluation of Clathrin-Mediated Endocytosis in the Plant Model Arabidopsis.” <i>Journal of Cell Science</i>.

The level of cortical tension outside of the cell-cell contact, when pulling at the contact edge, scales with the total size to which a cell-cell contact can grow1,2. Here we show in zebrafish primary germ layer progenitor cells that this monotonic relationship only applies to a narrow range of cortical tension increase, and that above a critical threshold, contact size inversely scales with cortical tension. This switch from cortical tension increasing to decreasing progenitor cell-cell contact size is caused by cortical tension promoting E-cadherin anchoring to the actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin at the contact. Once tension-mediated E-cadherin stabilization at the contact exceeds a critical threshold level, the rate by which the contact expands in response to pulling forces from the cortex sharply drops, leading to smaller contacts at physiologically relevant timescales of contact formation. Thus, the activity of cortical tension in expanding cell-cell contact size is limited by tension stabilizing E-cadherin-actin complexes at the contact."}]},{"year":"2018","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","intvolume":"        45","main_file_link":[{"url":"https://doi.org/10.1016/j.devcel.2018.04.002","open_access":"1"}],"date_published":"2018-05-07T00:00:00Z","type":"journal_article","quality_controlled":"1","abstract":[{"text":"Migrating cells penetrate tissue barriers during development, inflammatory responses, and tumor metastasis. We study if migration in vivo in such three-dimensionally confined environments requires changes in the mechanical properties of the surrounding cells using embryonic Drosophila melanogaster hemocytes, also called macrophages, as a model. We find that macrophage invasion into the germband through transient separation of the apposing ectoderm and mesoderm requires cell deformations and reductions in apical tension in the ectoderm. Interestingly, the genetic pathway governing these mechanical shifts acts downstream of the only known tumor necrosis factor superfamily member in Drosophila, Eiger, and its receptor, Grindelwald. Eiger-Grindelwald signaling reduces levels of active Myosin in the germband ectodermal cortex through the localization of a Crumbs complex component, Patj (Pals-1-associated tight junction protein). We therefore elucidate a distinct molecular pathway that controls tissue tension and demonstrate the importance of such regulation for invasive migration in vivo.","lang":"eng"}],"_id":"308","language":[{"iso":"eng"}],"external_id":{"pmid":["29738712"],"isi":["000432461400009"]},"day":"07","citation":{"ama":"Ratheesh A, Bicher J, Smutny M, et al.

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."}],"scopus_import":"1","issue":"12","page":"903-921","status":"public","isi":1,"date_updated":"2023-10-17T08:42:24Z","publication":"Journal of Histochemistry and Cytochemistry"},{"month":"05","department":[{"_id":"MiSi"},{"_id":"Bio"},{"_id":"EM-Fac"}],"project":[{"name":"Cytoskeletal force generation and force transduction of migrating leukocytes","grant_number":"281556","call_identifier":"FP7","_id":"25A603A2-B435-11E9-9278-68D0E5697425"},{"grant_number":"Y 564-B12","call_identifier":"FWF","_id":"25A8E5EA-B435-11E9-9278-68D0E5697425","name":"Cytoskeletal force generation and force transduction of migrating leukocytes"}],"author":[{"full_name":"Vaahtomeri, Kari","last_name":"Vaahtomeri","orcid":"0000-0001-7829-3518","id":"368EE576-F248-11E8-B48F-1D18A9856A87","first_name":"Kari"},{"first_name":"Markus","id":"3DAB9AFC-F248-11E8-B48F-1D18A9856A87","last_name":"Brown","full_name":"Brown, Markus"},{"first_name":"Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9843-3522","full_name":"Hauschild, Robert","last_name":"Hauschild"},{"last_name":"De Vries","full_name":"De Vries, Ingrid","first_name":"Ingrid","id":"4C7D837E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Leithner","full_name":"Leithner, Alexander F","orcid":"0000-0002-1073-744X","id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","first_name":"Alexander F"},{"first_name":"Matthias","id":"3C23B994-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8599-1226","full_name":"Mehling, Matthias","last_name":"Mehling"},{"full_name":"Kaufmann, Walter","last_name":"Kaufmann","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","first_name":"Walter","orcid":"0000-0001-9735-5315"},{"full_name":"Sixt, Michael K","last_name":"Sixt","first_name":"Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179"}],"volume":19,"pubrep_id":"900","oa":1,"doi":"10.1016/j.celrep.2017.04.027","publisher":"Cell Press","article_processing_charge":"Yes","tmp":{"image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","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"},"corr_author":"1","file":[{"access_level":"open_access","content_type":"application/pdf","date_created":"2018-12-12T10:14:54Z","file_size":2248814,"checksum":"8fdddaab1f1d76a6ec9ca94dcb6b07a2","file_name":"IST-2017-900-v1+1_1-s2.0-S2211124717305211-main.pdf","date_updated":"2020-07-14T12:47:38Z","file_id":"5109","relation":"main_file","creator":"system"}],"publication_status":"published","publist_id":"7052","oa_version":"Published Version","date_created":"2018-12-11T11:47:50Z","title":"Locally triggered release of the chemokine CCL21 promotes dendritic cell transmigration across lymphatic endothelia","publication_identifier":{"issn":["2211-1247"]},"isi":1,"publication":"Cell Reports","date_updated":"2025-09-10T14:27:34Z","file_date_updated":"2020-07-14T12:47:38Z","scopus_import":"1","issue":"5","ec_funded":1,"status":"public","page":"902 - 909","citation":{"ista":"Vaahtomeri K, Brown M, Hauschild R, de Vries I, Leithner AF, Mehling M, Kaufmann W, Sixt MK. 2017.

How monolayers cooperate with the penetrating cells to support their transit is poorly understood. We studied dendritic cell (DC) entry into lymphatic capillaries as a model system for transendothelial migration. We find that the chemokine CCL21, which is the decisive guidance cue for intravasation, mainly localizes in the trans-Golgi network and intracellular vesicles of lymphatic endothelial cells. Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes extracellularly enriched at the sites of endothelial cell-cell junctions. When we reconstitute the transmigration process in vitro, we find that secretion of CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and selective calcium chelation in lymphatic endothelium attenuates transmigration. Altogether, our data demonstrate a chemokine-mediated feedback between DCs and lymphatic endothelium, which facilitates transendothelial migration.","lang":"eng"}],"_id":"672","language":[{"iso":"eng"}],"date_published":"2017-05-02T00:00:00Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","ddc":["570"],"year":"2017","intvolume":"        19"}]
