Yet, it is unclear how to reconcile this remarkable self-organization capacity with classical experiments demonstrating key roles for extrinsic biases by maternal factors and/or extraembryonic tissues in embryogenesis. Here, we show that zebrafish embryonic tissue explants, prepared prior to germ layer induction and lacking extraembryonic tissues, can specify all germ layers and form a seemingly complete mesendoderm anlage. Importantly, explant organization requires polarized inheritance of maternal factors from dorsal-marginal regions of the blastoderm. Moreover, induction of endoderm and head-mesoderm, which require peak Nodal-signaling levels, is highly variable in explants, reminiscent of embryos with reduced Nodal signals from the extraembryonic tissues. Together, these data suggest that zebrafish explants do not undergo bona fide self-organization, but rather display features of genetically encoded self-assembly, where intrinsic genetic programs control the emergence of order.","lang":"eng"}],"intvolume":"         9","quality_controlled":"1","date_published":"2020-04-06T00:00:00Z","year":"2020","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)"},"oa":1,"scopus_import":"1","project":[{"_id":"260F1432-B435-11E9-9278-68D0E5697425","name":"Interaction and feedback between cell mechanics and fate specification in vertebrate gastrulation","call_identifier":"H2020","grant_number":"742573"},{"name":"Mesendoderm specification in zebrafish: The role of extraembryonic tissues","_id":"26B1E39C-B435-11E9-9278-68D0E5697425","grant_number":"25239"},{"grant_number":"ALTF 850-2017","name":"Coordination of mesendoderm cell fate specification and internalization during zebrafish gastrulation","_id":"26520D1E-B435-11E9-9278-68D0E5697425"},{"name":"Coordination of mesendoderm fate specification and internalization during zebrafish gastrulation","_id":"266BC5CE-B435-11E9-9278-68D0E5697425","grant_number":"LT000429"}],"file_date_updated":"2020-07-14T12:48:04Z","corr_author":"1","article_number":"e55190","has_accepted_license":"1","citation":{"ama":"Schauer A, Nunes Pinheiro DC, Hauschild R, Heisenberg C-PJ.

They are usually inspired by – and fitted to – experimental data, but they rarely produce neural dynamics that serve complex functions. These failures suggest that current plasticity models are still under-constrained by existing data. Here, we present an alternative approach that uses meta-learning to discover plausible synaptic plasticity rules. Instead of experimental data, the rules are constrained by the functions they implement and the structure they are meant to produce. Briefly, we parameterize synaptic plasticity rules by a Volterra expansion and then use supervised learning methods (gradient descent or evolutionary strategies) to minimize a problem-dependent loss function that quantifies how effectively a candidate plasticity rule transforms an initially random network into one with the desired function. We first validate our approach by re-discovering previously described plasticity rules, starting at the single-neuron level and “Oja’s rule”, a simple Hebbian plasticity rule that captures the direction of most variability of inputs to a neuron (i.e., the first principal component). We expand the problem to the network level and ask the framework to find Oja’s rule together with an anti-Hebbian rule such that an initially random two-layer firing-rate network will recover several principal components of the input space after learning. Next, we move to networks of integrate-and-fire neurons with plastic inhibitory afferents. We train for rules that achieve a target firing rate by countering tuned excitation. Our algorithm discovers a specific subset of the manifold of rules that can solve this task. Our work is a proof of principle of an automated and unbiased approach to unveil synaptic plasticity rules that obey biological constraints and can solve complex functions.","lang":"eng"}],"year":"2020","date_published":"2020-12-06T00:00:00Z","oa":1,"day":"06","_id":"9633","publication":"Advances in Neural Information Processing Systems","title":"A meta-learning approach to (re)discover plasticity rules that carve a desired function into a neural network","ec_funded":1,"volume":33},{"publication":"Nonlinear Analysis: Hybrid Systems","volume":36,"title":"Abstraction based verification of stability of polyhedral switched systems","article_type":"original","_id":"7426","day":"01","publisher":"Elsevier","ddc":["000"],"date_published":"2020-05-01T00:00:00Z","issue":"5","year":"2020","tmp":{"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","image":"/images/cc_by_nc_nd.png"},"oa":1,"intvolume":"        36","date_created":"2020-02-02T23:00:59Z","abstract":[{"text":"This paper presents a novel abstraction technique for analyzing Lyapunov and asymptotic stability of polyhedral switched systems. A polyhedral switched system is a hybrid system in which the continuous dynamics is specified by polyhedral differential inclusions, the invariants and guards are specified by polyhedral sets and the switching between the modes do not involve reset of variables. A finite state weighted graph abstracting the polyhedral switched system is constructed from a finite partition of the state–space, such that the satisfaction of certain graph conditions, such as the absence of cycles with product of weights on the edges greater than (or equal) to 1, implies the stability of the system. However, the graph is in general conservative and hence, the violation of the graph conditions does not imply instability. If the analysis fails to establish stability due to the conservativeness in the approximation, a counterexample (cycle with product of edge weights greater than or equal to 1) indicating a potential reason for the failure is returned. Further, a more precise approximation of the switched system can be constructed by considering a finer partition of the state–space in the construction of the finite weighted graph. We present experimental results on analyzing stability of switched systems using the above method.","lang":"eng"}],"quality_controlled":"1","external_id":{"isi":["000528828600003"]},"file":[{"checksum":"560abfddb53f9fe921b6744f59f2cfaa","embargo":"2022-05-15","relation":"main_file","file_size":818774,"file_name":"2020_NAHS_GarciaSoto.pdf","date_updated":"2022-05-16T22:30:04Z","creator":"dernst","content_type":"application/pdf","file_id":"8688","date_created":"2020-10-21T13:16:45Z","access_level":"open_access"}],"publication_identifier":{"issn":["1751-570X"]},"month":"05","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","scopus_import":"1","project":[{"_id":"25863FF4-B435-11E9-9278-68D0E5697425","name":"Game Theory","call_identifier":"FWF","grant_number":"S11407"},{"grant_number":"Z211","name":"Formal methods for the design and analysis of complex systems","_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"file_date_updated":"2022-05-16T22:30:04Z","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","corr_author":"1","has_accepted_license":"1","article_number":"100856","citation":{"mla":"Garcia Soto, Miriam, and Pavithra Prabhakar. “Abstraction Based Verification of Stability of Polyhedral Switched Systems.” <i>Nonlinear Analysis: Hybrid Systems</i>, vol. 36, no. 5, 100856, Elsevier, 2020, doi:<a href=\"https://doi.org/10.1016/j.nahs.2020.100856\">10.1016/j.nahs.2020.100856</a>.","ieee":"M.

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","lang":"eng"}],"date_created":"2020-02-26T10:56:37Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","month":"02","file":[{"file_name":"Pradeep Bhandari Thesis.pdf","date_updated":"2021-03-01T23:30:04Z","file_size":9646346,"checksum":"4589234fdb12b4ad72273b311723a7b4","title":"Localization and functional role of Cav2.3 in the medial habenula to interpeduncular nucleus pathway","relation":"main_file","embargo":"2021-02-28","date_created":"2020-02-28T08:37:53Z","access_level":"open_access","file_id":"7538","creator":"pbhandari","content_type":"application/pdf"},{"date_created":"2020-02-28T08:47:14Z","access_level":"closed","file_id":"7539","creator":"pbhandari","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","file_name":"Pradeep Bhandari Thesis.docx","date_updated":"2021-03-01T23:30:04Z","file_size":35252164,"embargo_to":"open_access","checksum":"aa79490553ca0a5c9b6fbcd152e93928","title":"Localization and functional role of Cav2.3 in the medial habenula to interpeduncular nucleus pathway","relation":"source_file"}],"page":"79","acknowledged_ssus":[{"_id":"EM-Fac"}],"publication_identifier":{"issn":["2663-337X"]},"citation":{"ama":"Bhandari P.

Assembly and activation of this machinery are coordinated by the tubulin-related GTPase FtsZ, which was found to form treadmilling filaments on supported bilayers in vitro1, as well as in live cells, in which filaments circle around the cell division site2,3. Treadmilling of FtsZ is thought to actively move proteins around the division septum, thereby distributing peptidoglycan synthesis and coordinating the inward growth of the septum to form the new poles of the daughter cells4. However, the molecular mechanisms underlying this function are largely unknown. Here, to study how FtsZ polymerization dynamics are coupled to downstream proteins, we reconstituted part of the bacterial cell division machinery using its purified components FtsZ, FtsA and truncated transmembrane proteins essential for cell division. We found that the membrane-bound cytosolic peptides of FtsN and FtsQ co-migrated with treadmilling FtsZ–FtsA filaments, but despite their directed collective behaviour, individual peptides showed random motion and transient confinement. Our work suggests that divisome proteins follow treadmilling FtsZ filaments by a diffusion-and-capture mechanism, which can give rise to a moving zone of signalling activity at the division site."}],"date_created":"2020-01-28T16:14:41Z","intvolume":"         5","main_file_link":[{"url":"http://europepmc.org/article/PMC/7048620","open_access":"1"}],"quality_controlled":"1","related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"14280"}],"link":[{"relation":"press_release","description":"News on IST Homepage","url":"https://ist.ac.at/en/news/little-cell-big-cover-story/"}]},"acknowledgement":"We acknowledge members of the Loose laboratory at IST Austria for helpful discussions—in particular, P.

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."}],"intvolume":"       105","date_created":"2020-02-10T15:59:45Z","quality_controlled":"1","volume":105,"title":"Functional electron microscopy (“Flash and Freeze”) of identified cortical synapses in acute brain slices","article_type":"original","ec_funded":1,"publication":"Neuron","ddc":["570"],"pmid":1,"_id":"7473","day":"18","publisher":"Elsevier","author":[{"last_name":"Borges Merjane","full_name":"Borges Merjane, Carolina","first_name":"Carolina","orcid":"0000-0003-0005-401X","id":"4305C450-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Kim, Olena","last_name":"Kim","orcid":"0000-0003-2344-1039","id":"3F8ABDDA-F248-11E8-B48F-1D18A9856A87","first_name":"Olena"},{"id":"353C1B58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5001-4804","first_name":"Peter M","last_name":"Jonas","full_name":"Jonas, Peter M"}],"article_processing_charge":"No","date_updated":"2026-05-13T22:30:33Z","department":[{"_id":"PeJo"}],"isi":1,"status":"public","doi":"10.1016/j.neuron.2019.12.022","publication_status":"published","oa_version":"Published Version","type":"journal_article","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","month":"03","external_id":{"isi":["000520854700008"],"pmid":["31928842"]},"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).

Owing to their inability to migrate, plant cells rely on targeted cell division and expansion to regenerate wounds. Strict coordination of these wound-induced responses is essential to ensure efficient, spatially restricted wound healing. Single-cell tracking by live imaging allowed us to gain mechanistic insight into the wound perception and coordination of wound responses after laser-based wounding in Arabidopsis root. We revealed a crucial contribution of the collapse of damaged cells in wound perception and detected an auxin increase specific to cells immediately adjacent to the wound. This localized auxin increase balances wound-induced cell expansion and restorative division rates in a dose-dependent manner, leading to tumorous overproliferation when the canonical TIR1 auxin signaling is disrupted. Auxin and wound-induced turgor pressure changes together also spatially define the activation of key components of regeneration, such as the transcription regulator ERF115. Our observations suggest that the wound signaling involves the sensing of collapse of damaged cells and a local auxin signaling activation to coordinate the downstream transcriptional responses in the immediate wound vicinity."}],"intvolume":"       117","date_created":"2020-06-22T13:33:52Z","year":"2020","issue":"26","date_published":"2020-06-30T00:00:00Z","oa":1,"tmp":{"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","image":"/images/cc_by_nc_nd.png"},"publisher":"National Academy of Sciences","day":"30","_id":"8002","pmid":1,"ddc":["580"],"publication":"Proceedings of the National Academy of Sciences of the United States of America","ec_funded":1,"article_type":"original","title":"Wounding-induced changes in cellular pressure and localized auxin signalling spatially coordinate restorative divisions in roots","volume":117,"OA_place":"publisher"},{"doi":"10.1016/j.xplc.2020.100048","publication_status":"published","oa_version":"Published Version","type":"journal_article","isi":1,"status":"public","date_updated":"2026-05-13T22:30:46Z","department":[{"_id":"EvBe"}],"article_processing_charge":"No","author":[{"id":"42FE702E-F248-11E8-B48F-1D18A9856A87","first_name":"Hana","full_name":"Semeradova, Hana","last_name":"Semeradova"},{"id":"310A8E3E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9179-6099","first_name":"Juan C","last_name":"Montesinos López","full_name":"Montesinos López, Juan C"},{"first_name":"Eva","orcid":"0000-0002-8510-9739","id":"38F4F166-F248-11E8-B48F-1D18A9856A87","last_name":"Benková","full_name":"Benková, Eva"}],"scopus_import":"1","project":[{"grant_number":"24746","name":"Molecular mechanisms of the cytokinin regulated endomembrane trafficking to coordinate plant organogenesis","_id":"261821BC-B435-11E9-9278-68D0E5697425"},{"_id":"253E54C8-B435-11E9-9278-68D0E5697425","name":"Molecular mechanism of auxindriven formative divisions delineating lateral root organogenesis in plants","grant_number":"ALTF710-2016"}],"file_date_updated":"2021-02-18T10:23:59Z","corr_author":"1","article_number":"100048","has_accepted_license":"1","citation":{"chicago":"Semerádová, Hana, Juan C Montesinos López, and Eva Benková. “All Roads Lead to Auxin: Post-Translational Regulation of Auxin Transport by Multiple Hormonal Pathways.” <i>Plant Communications</i>.

The unique feature of auxin is its polar, cell-to-cell transport that leads to the formation of local auxin maxima and gradients, which coordinate initiation and patterning of plant organs. The molecular machinery mediating polar auxin transport is one of the important points of interaction with other hormones. Multiple hormonal pathways converge at the regulation of auxin transport and form a regulatory network that integrates various developmental and environmental inputs to steer plant development. In this review, we discuss recent advances in understanding the mechanisms that underlie regulation of polar auxin transport by multiple hormonal pathways. Specifically, we focus on the post-translational mechanisms that contribute to fine-tuning of the abundance and polarity of auxin transporters at the plasma membrane and thereby enable rapid modification of the auxin flow to coordinate plant growth and development.","lang":"eng"}],"intvolume":"         1","date_created":"2021-02-18T10:18:43Z","quality_controlled":"1","date_published":"2020-05-11T00:00:00Z","issue":"3","year":"2020","tmp":{"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","image":"/images/cc_by_nc_nd.png"},"oa":1,"_id":"9160","day":"11","publisher":"Elsevier","ddc":["580"],"pmid":1,"publication":"Plant Communications","volume":1,"OA_place":"publisher","article_type":"original","title":"All roads lead to auxin: Post-translational regulation of auxin transport by multiple hormonal pathways"},{"date_updated":"2026-05-13T22:30:47Z","department":[{"_id":"GeKa"}],"article_processing_charge":"No","author":[{"first_name":"Kushagra","orcid":"0000-0001-9985-9293","id":"b22ab905-3539-11eb-84c3-fc159dcd79cb","full_name":"Aggarwal, Kushagra","last_name":"Aggarwal"},{"full_name":"Hofmann, Andrea C","last_name":"Hofmann","id":"340F461A-F248-11E8-B48F-1D18A9856A87","first_name":"Andrea C"},{"last_name":"Jirovec","full_name":"Jirovec, Daniel","first_name":"Daniel","id":"4C473F58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7197-4801"},{"last_name":"Prieto Gonzalez","full_name":"Prieto Gonzalez, Ivan","first_name":"Ivan","id":"2A307FE2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7370-5357"},{"first_name":"Amir","last_name":"Sammak","full_name":"Sammak, Amir"},{"first_name":"Marc","last_name":"Botifoll","full_name":"Botifoll, Marc"},{"first_name":"Sara","full_name":"Marti-Sanchez, Sara","last_name":"Marti-Sanchez"},{"last_name":"Veldhorst","full_name":"Veldhorst, Menno","first_name":"Menno"},{"last_name":"Arbiol","full_name":"Arbiol, Jordi","first_name":"Jordi"},{"first_name":"Giordano","full_name":"Scappucci, Giordano","last_name":"Scappucci"},{"full_name":"Katsaros, Georgios","last_name":"Katsaros","first_name":"Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8342-202X"}],"publication_status":"draft","doi":"10.48550/arXiv.2012.00322","type":"preprint","oa_version":"Submitted Version","status":"public","related_material":{"record":[{"id":"10559","relation":"later_version","status":"public"},{"relation":"research_data","status":"public","id":"8834"},{"id":"10058","relation":"dissertation_contains","status":"public"}]},"acknowledgement":"This research and related results were made possible with the support of the NOMIS Foundation.

A key challenge towards hybrid germanium quantum technology is the design of high quality interfaces and superconducting contacts that are robust against magnetic fields. By combining the assets of Al, which has a long superconducting coherence, and Nb, which has a significant superconducting gap, we form low-disordered JoFETs with large ICRN products that are capable of withstanding high magnetic fields. We furthermore demonstrate the ability of phase-biasing individual JoFETs opening up an avenue to explore topological superconductivity in planar Ge.

Here, we introduce Darea software, which utilizes deep learning for analysis of replica images and demonstrate its usefulness for quick measurements of the pre- and postsynaptic areas, density and distribution of gold particles at synapses in a reproducible manner. We used Darea for comparing glutamate receptor and calcium channel distributions between hippocampal CA3-CA1 spine synapses on apical and basal dendrites, which differ in signaling pathways involved in synaptic plasticity. We found that apical synapses express a higher density of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and a stronger increase of AMPA receptors with synaptic size, while basal synapses show a larger increase in N-methyl-D-aspartate (NMDA) receptors with size. Interestingly, AMPA and NMDA receptors are segregated within postsynaptic sites and negatively correlated in density among both apical and basal synapses. In the presynaptic sites, Cav2.1 voltage-gated calcium channels show similar densities in apical and basal synapses with distributions consistent with an exclusion zone model of calcium channel-release site topography.","lang":"eng"}],"intvolume":"        21","date_created":"2020-09-20T22:01:35Z","quality_controlled":"1","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)"},"oa":1,"date_published":"2020-09-14T00:00:00Z","year":"2020","issue":"18","citation":{"ama":"Kleindienst D, Montanaro-Punzengruber J-C, Bhandari P, Case MJ, Fukazawa Y, Shigemoto R.

Quantitative studies anchor translation into the context of bacterial physiology and reveal several mathematical relationships, called “growth laws,” which capture physiological feedbacks between protein synthesis and cell growth. Growth laws describe the dependency of the ribosome abundance as a function of growth rate, which can change depending on the growth conditions. Perturbations of translation reveal that bacteria employ a compensatory strategy in which the reduced translation capability results in increased expression of the translation machinery.\r\nPerturbations of translation are achieved in various ways; clinically interesting is the application of translation-targeting antibiotics – translation inhibitors. The antibiotic effects on bacterial physiology are often poorly understood. Bacterial responses to two or more simultaneously applied antibiotics are even more puzzling. The combined antibiotic effect determines the type of drug interaction, which ranges from synergy (the effect is stronger than expected) to antagonism (the effect is weaker) and suppression (one of the drugs loses its potency).\r\nIn the first part of this work, we systematically measure the pairwise interaction network for translation inhibitors that interfere with different steps in translation. We find that the interactions are surprisingly diverse and tend to be more antagonistic. To explore the underlying mechanisms, we begin with a minimal biophysical model of combined antibiotic action. We base this model on the kinetics of antibiotic uptake and binding together with the physiological response described by the growth laws. The biophysical model explains some drug interactions, but not all; it specifically fails to predict suppression.\r\nIn the second part of this work, we hypothesize that elusive suppressive drug interactions result from the interplay between ribosomes halted in different stages of translation. To elucidate this putative mechanism of drug interactions between translation inhibitors, we generate translation bottlenecks genetically using in- ducible control of translation factors that regulate well-defined translation cycle steps. These perturbations accurately mimic antibiotic action and drug interactions, supporting that the interplay of different translation bottlenecks partially causes these interactions.\r\nWe extend this approach by varying two translation bottlenecks simultaneously. This approach reveals the suppression of translocation inhibition by inhibited translation. We rationalize this effect by modeling dense traffic of ribosomes that move on transcripts in a translation factor-mediated manner. This model predicts a dissolution of traffic jams caused by inhibited translocation when the density of ribosome traffic is reduced by lowered initiation. We base this model on the growth laws and quantitative relationships between different translation and growth parameters.\r\nIn the final part of this work, we describe a set of tools aimed at quantification of physiological and translation parameters. We further develop a simple model that directly connects the abundance of a translation factor with the growth rate, which allows us to extract physiological parameters describing initiation. We demonstrate the development of tools for measuring translation rate.\r\nThis thesis showcases how a combination of high-throughput growth rate mea- surements, genetics, and modeling can reveal mechanisms of drug interactions. Furthermore, by a gradual transition from combinations of antibiotics to precise genetic interventions, we demonstrated the equivalency between genetic and chemi- cal perturbations of translation. These findings tile the path for quantitative studies of antibiotic combinations and illustrate future approaches towards the quantitative description of translation.","lang":"eng"}],"month":"10","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-011-4"]},"related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"7673"},{"id":"8250","status":"public","relation":"part_of_dissertation"}]},"page":"271","file":[{"date_updated":"2021-10-07T22:30:03Z","file_name":"kavcicB_thesis202009.pdf","file_size":52636162,"checksum":"d708ecd62b6fcc3bc1feb483b8dbe9eb","embargo":"2021-10-06","relation":"main_file","date_created":"2020-10-15T06:41:20Z","access_level":"open_access","file_id":"8663","creator":"bkavcic","content_type":"application/pdf"},{"file_size":321681247,"relation":"source_file","embargo_to":"open_access","checksum":"bb35f2352a04db19164da609f00501f3","date_updated":"2021-10-07T22:30:03Z","file_name":"2020b.zip","creator":"bkavcic","content_type":"application/zip","access_level":"closed","date_created":"2020-10-15T06:41:53Z","file_id":"8664"}],"acknowledgement":"I thank Life Science Facilities for their continuous support with providing top-notch laboratory materials, keeping the devices humming, and coordinating the repairs and building of custom-designed laboratory equipment with the MIBA Machine shop.","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"M-Shop"}],"language":[{"iso":"eng"}],"citation":{"chicago":"Kavcic, Bor. “Perturbations of Protein Synthesis: From Antibiotics to Genetics and Physiology.” Institute of Science and Technology Austria, 2020. <a href=\"https://doi.org/10.15479/AT:ISTA:8657\">https://doi.org/10.15479/AT:ISTA:8657</a>.","apa":"Kavcic, B.

The cellular and molecular mechanisms regulating the specific sequential steps of radial neuronal migration in vivo are however still unclear, let alone the effects and interactions with the extracellular environment. In any in vivo context, cells will always be exposed to a complex extracellular environment consisting of (1) secreted factors acting as potential signaling cues, (2) the extracellular matrix, and (3) other cells providing cell–cell interaction through receptors and/or direct physical stimuli. Most studies so far have described and focused mainly on intrinsic cell-autonomous gene functions in neuronal migration but there is accumulating evidence that non-cell-autonomous-, local-, systemic-, and/or whole tissue-wide effects substantially contribute to the regulation of radial neuronal migration. These non-cell-autonomous effects may differentially affect cortical neuron migration in distinct cellular environments. However, the cellular and molecular natures of such non-cell-autonomous mechanisms are mostly unknown. Furthermore, physical forces due to collective migration and/or community effects (i.e., interactions with surrounding cells) may play important roles in neocortical projection neuron migration. In this concise review, we first outline distinct models of non-cell-autonomous interactions of cortical projection neurons along their radial migration trajectory during development. We then summarize experimental assays and platforms that can be utilized to visualize and potentially probe non-cell-autonomous mechanisms. Lastly, we define key questions to address in the future.","lang":"eng"}],"date_created":"2020-09-26T06:11:07Z","intvolume":"         8","title":"Non-cell-autonomous mechanisms in radial projection neuron migration in the developing cerebral cortex","article_type":"original","ec_funded":1,"volume":8,"publication":"Frontiers in Cell and Developmental Biology","pmid":1,"ddc":["570"],"day":"25","publisher":"Frontiers","_id":"8569","author":[{"full_name":"Hansen, Andi H","last_name":"Hansen","id":"38853E16-F248-11E8-B48F-1D18A9856A87","first_name":"Andi H"},{"last_name":"Hippenmeyer","full_name":"Hippenmeyer, Simon","id":"37B36620-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2279-1061","first_name":"Simon"}],"article_processing_charge":"Yes (via OA deal)","department":[{"_id":"SiHi"}],"date_updated":"2026-05-13T22:30:51Z","status":"public","isi":1,"oa_version":"Published Version","type":"journal_article","doi":"10.3389/fcell.2020.574382","publication_status":"published","month":"09","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_identifier":{"issn":["2296-634X"]},"external_id":{"pmid":["33102480"],"isi":["000577915900001"]},"acknowledgement":"AH was a recipient of a DOC Fellowship (24812) of the Austrian Academy of Sciences.

Here, we explain these interactions by “translation bottlenecks”: points in the translation cycle where antibiotics block ribosomal progression. To elucidate the underlying mechanisms of drug interactions between translation inhibitors, we generate translation bottlenecks genetically using inducible control of translation factors that regulate well-defined translation cycle steps. These perturbations accurately mimic antibiotic action and drug interactions, supporting that the interplay of different translation bottlenecks causes these interactions. We further show that growth laws, combined with drug uptake and binding kinetics, enable the direct prediction of a large fraction of observed interactions, yet fail to predict suppression. However, varying two translation bottlenecks simultaneously supports that dense traffic of ribosomes and competition for translation factors account for the previously unexplained suppression. These results highlight the importance of “continuous epistasis” in bacterial physiology.","lang":"eng"}],"year":"2020","date_published":"2020-08-11T00:00:00Z","oa":1,"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)"}},{"acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"SSU"}],"related_material":{"record":[{"status":"public","relation":"later_version","id":"10766"},{"id":"9623","status":"public","relation":"dissertation_contains"}]},"page":"41","acknowledgement":"We would like to thank Edouard Hannezo for discussions, Shayan Shami Pour and Daniel Capek for help with data analysis, Vanessa Barone and other members of the Heisenberg laboratory for thoughtful discussions and comments on the manuscript.

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."}],"date_created":"2021-07-29T11:29:50Z","status":"public"},{"oa_version":"Preprint","type":"preprint","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1101/2020.04.18.047886 "}],"doi":"10.1101/2020.04.18.047886","publication_status":"published","date_created":"2020-04-22T08:27:56Z","abstract":[{"lang":"eng","text":"Combining drugs can improve the efficacy of treatments. However, predicting the effect of drug combinations is still challenging. The combined potency of drugs determines the drug interaction, which is classified as synergistic, additive, antagonistic, or suppressive. While probabilistic, non-mechanistic models exist, there is currently no biophysical model that can predict antibiotic interactions. Here, we present a physiologically relevant model of the combined action of antibiotics that inhibit protein synthesis by targeting the ribosome. This model captures the kinetics of antibiotic binding and transport, and uses bacterial growth laws to predict growth in the presence of antibiotic combinations. We find that this biophysical model can produce all drug interaction types except suppression. We show analytically that antibiotics which cannot bind to the ribosome simultaneously generally act as substitutes for one another, leading to additive drug interactions. Previously proposed null expectations for higher-order drug interactions follow as a limiting case of our model. We further extend the model to include the effects of direct physical or allosteric interactions between individual drugs on the ribosome. Notably, such direct interactions profoundly change the combined drug effect, depending on the kinetic parameters of the drugs used. The model makes additional predictions for the effects of resistance genes on drug interactions and for interactions between ribosome-targeting antibiotics and antibiotics with other targets. These findings enhance our understanding of the interplay between drug action and cell physiology and are a key step toward a general framework for predicting drug interactions."}],"status":"public","department":[{"_id":"GaTk"}],"year":"2020","date_updated":"2026-05-13T22:30:50Z","date_published":"2020-04-18T00:00:00Z","oa":1,"author":[{"last_name":"Kavcic","full_name":"Kavcic, Bor","orcid":"0000-0001-6041-254X","id":"350F91D2-F248-11E8-B48F-1D18A9856A87","first_name":"Bor"},{"last_name":"Tkačik","full_name":"Tkačik, Gašper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6699-1455","first_name":"Gašper"},{"orcid":"0000-0003-4398-476X","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87","first_name":"Tobias","last_name":"Bollenbach","full_name":"Bollenbach, Tobias"}],"article_processing_charge":"No","day":"18","project":[{"call_identifier":"FWF","_id":"25E9AF9E-B435-11E9-9278-68D0E5697425","name":"Revealing the mechanisms underlying drug interactions","grant_number":"P27201-B22"},{"grant_number":"P28844-B27","call_identifier":"FWF","_id":"254E9036-B435-11E9-9278-68D0E5697425","name":"Biophysics of information processing in gene regulation"}],"publisher":"Cold Spring Harbor Laboratory","_id":"7673","language":[{"iso":"eng"}],"citation":{"mla":"Kavcic, Bor, et al. “A Minimal Biophysical Model of Combined Antibiotic Action.” <i>BioRxiv</i>, Cold Spring Harbor Laboratory, 2020, doi:<a href=\"https://doi.org/10.1101/2020.04.18.047886\">10.1101/2020.04.18.047886</a>.","ista":"Kavcic B, Tkačik G, Bollenbach MT. 2020.
