The driving functional is a modification of the classical relative entropy that also makes use of the information at the boundary. As an intermediate result, when $\\Omega$ is an interval in $\\mathbb{R}^1$, we find a formula for the descending slope of this geodesically nonconvex functional.

However, the predicted scaling from a microscopic behavior—dominated by quantum fluctuations—to a macroscopic one—characterized by stable phases—and the associated exponents and phase diagram have not been observed so far. In this work we couple a single transmon qubit with a fixed coupling strength 𝑔 to a superconducting cavity that is in situ bandwidth 𝜅 tunable to controllably approach this thermodynamic limit. Even though the system remains microscopic, we observe its behavior becoming increasingly macroscopic as a function of 𝑔/𝜅. For the highest realized 𝑔/𝜅 of approximately 287, the system switches with a characteristic timescale as long as 6 s between a bright coherent state with approximately 8×103 intracavity photons and the vacuum state. This exceeds the microscopic timescales by 6 orders of magnitude and approaches the perfect hysteresis expected between two macroscopic attractors in the thermodynamic limit. These findings and interpretation are qualitatively supported by neoclassical theory and large-scale quantum-jump Monte Carlo simulations. Besides shedding more light on driven-dissipative physics in the limit of strong light-matter coupling, this system might also find applications in quantum sensing and metrology.","lang":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","acknowledged_ssus":[{"_id":"M-Shop"}],"file":[{"relation":"main_file","access_level":"open_access","checksum":"0833880d47f74ad1deda93a1d8ffa5a7","date_updated":"2024-06-28T12:04:43Z","content_type":"application/pdf","creator":"cchlebak","file_id":"17185","success":1,"file_name":"2024_PRXQuantum_Sett.pdf","file_size":1443351,"date_created":"2024-06-28T12:04:43Z"}],"intvolume":"         5","external_id":{"isi":["001171652500001"],"arxiv":["2210.14182"]},"issue":"1","oa_version":"Published Version","researchdata_availability":"yes","_id":"17183","status":"public","acknowledgement":"This work has received funding from the Austrian Science Fund (FWF) through BeyondC (F7105) and the European Union’s Horizon 2020 research and innovation program under Grant Agreement No. 862644 (FETopen QUARTET).

As the field continues to advance, there are\r\ntechnical challenges that need to be addressed in order to take full advantage of the spatial\r\ncapabilities of these methods. In this work, I present two technical developments that I\r\nestablished for multiplexed error robust FISH (MERFISH) throughout my PhD: (1) pushing the\r\nspatial resolution limits to the nanoscale, and (2) adding rich tissue context to the mouse brain\r\ntranscriptome. To achieve nanoscale resolution with MERFISH in cultured cells, I combined it\r\nwith stimulated emission depletion (STED) and expansion microscopy (ExM) to achieve a\r\nspatial resolution as low as ~20 nm, and explored the compatibility of MERFISH with singlemolecule localization microscopy (SMLM) techniques. To visualize targeted mRNAs in mouse\r\nbrain tissue, I applied the comprehensive analysis of tissues across scales (CATS) toolbox, which\r\nprovides an unbiased morphological readout by labeling the extracellular domain. I\r\nsuccessfully established this method, which we call CATS-MERFISH-ExM, to work with thick\r\nmouse brain slices, being able to extract transcriptomics information with 3D tissue context.\r\nCATS-MERFISH-ExM enabled us to identify cell types and further visualize the subcellular\r\ndistribution of transcripts in mouse brain tissue, shedding light on the neuropil-specific\r\ntranscriptome. This method provides integrated information on cellular structure and\r\ntranscriptomes in situ, and could potentially be applied with other modalities, opening new\r\navenues for scientific discovery.

Consequentially, the nature of this visual processing then depends on what is the\r\nrelevant information in a scene and on the notion of efficiency. In this work, I study how visual\r\nprocessing is modulated by two different variations in the visual scene. First, I discovered that\r\nin the mouse (Mus musculus) retina, Retinal Ganglion Cells in the upper and lower visual\r\nfield have differences in the center surround structure of their receptive fields. Comparison\r\nwith models of efficient coding show that this adaptation likely evolved to cope with the\r\nbrightness gradient from the sky to the ground that is pervasive in natural scenes. In the\r\nsecond project, I study how the downstream neurons in the Superior Colliculus dynamically\r\nchange their temporal selectivity depending on the ambient luminance and behavioral state.\r\nAs the scene gets darker or when the animal is is less aroused, the neuronal responses get\r\nlaggier, while still maintaining their relative timing with respect to the population. Overall, this\r\nwork emphasises the need to understand visual processing in the context of specific demands\r\nof the animal in its the environment. The adaptive changes in the visual system, from the\r\nretinal ganglion cells to the superior colliculus, highlight the intricate ways in which biological\r\nvision optimizes the processing of visual information.\r\n"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","OA_embargo":"12","date_updated":"2026-10-02T11:33:52Z","alternative_title":["ISTA Thesis"],"related_material":{"record":[{"relation":"part_of_dissertation","id":"12349","status":"public"},{"relation":"research_data","id":"12370","status":"public"}]},"project":[{"grant_number":"101086580","name":"Action Selection in the Midbrain: Neuromodulation of Visuomotor Senses","_id":"bdaf81a8-d553-11ed-ba76-c95961984540"},{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","call_identifier":"H2020","grant_number":"665385"},{"grant_number":"756502","call_identifier":"H2020","_id":"2634E9D2-B435-11E9-9278-68D0E5697425","name":"Circuits of Visual Attention"}],"degree_awarded":"PhD","supplementarymaterial":"unclear","date_created":"2024-11-20T21:30:44Z","article_processing_charge":"No","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","month":"11","language":[{"iso":"eng"}],"department":[{"_id":"GradSch"},{"_id":"MaJö"}],"publication_status":"published","page":"86","doi_confirm":"1","doi":"10.15479/at:ista:18574","type":"dissertation","publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-050-3"]},"title":"Visual adaptations to natural statistics","oa":1,"author":[{"id":"2A485EBE-F248-11E8-B48F-1D18A9856A87","last_name":"Gupta","full_name":"Gupta, Divyansh","orcid":"0000-0001-7400-6665","first_name":"Divyansh"}],"corr_author":"1"},{"abstract":[{"text":"Data analysis files for the manuscript \"Emergent Macroscopic Bistability Induced by a Single Superconducting Qubit\".\r\n\r\nThis contains the raw data and the data analysis files for generating the figures in the manuscript.\r\n\r\n Figure1 file - The raw data of cavity transmission spectra for 6 different kappas are there.

While distinct in their focus, these different perspectives have a common\r\ntheme: chemiosmotic theory and utilisation of the proton gradient for driving the essential\r\nprocesses like auxin efflux and ATP synthesis, effectively bridging the membrane protein\r\nstructure and function from the realms of plant biology and cellular bioenergetics.\r\nThe first project of this thesis centres on the characterisation of PIN proteins, a class of\r\ntransmembrane transporters pivotal in the regulation of auxin transport and distribution in\r\nplants. PINs form a conserved and phylogenetically abundant group of transporters present in\r\nland plants and certain algae. Despite their great importance, they were one of the few elusive\r\nproteins essential for plant development not to be structurally and mechanistically\r\ncharacterised since their discovery almost 30 years ago. This work aimed to uncover the\r\nstructural and functional dynamics of the PIN protein-mediated auxin transport using an array\r\nof experimental techniques, including protein purification, biochemical assays and structural\r\nanalysis. Through an exhaustive screening process that took several years and included testing\r\ndifferent PIN homologues, expression systems, constructs, and purification conditions, we\r\ndeveloped a robust protocol for isolating the pure, stable, and monodisperse PIN8 protein.\r\nMoreover, utilising biophysical methods and buffer screening, we demonstrated that PIN8\r\nexhibits detergent and pH-dependent stability, with mild detergents and lower pH (5.0 and 6.0)\r\nbeing optimal for the stability of the protein. Using SEC-MALS and crosslinking, we\r\ndetermined that PIN8 forms dimers, which was confirmed by our structural studies. We\r\nobtained a cryo-EM map of PIN8 at pH 6.0, and, compared to recently published structures,\r\nour map implies major pH-dependent conformational changes and possibly utilisation of the\r\nproton gradient in the transport mechanism.\r\nThe subject of the second project was F1Fo-ATP synthase, an enzyme complex fundamental\r\nto cellular energy metabolism. Through an approach integrating biochemical assays and\r\nstructural analysis, this research aimed to unveil the molecular mechanism of inhibition of ATP\r\nsynthase by yaku´amide, a bioactive compound with potential therapeutic implications. Using\r\nsubmitochondrial particles and purified F1Fo-ATP synthase, we demonstrated that, contrary to\r\npublished data, yaku´amide inhibits both ATP hydrolysis and ATP synthesis reactions.\r\nMoreover, we found that yaku´amide inhibitory activity is proton motive force (pmf)\r\ndependent, with lower inhibition in a more coupled system. Utilising cryo-EM, we obtained\r\nmaps and models for the three main rotational states of murine ATP synthase (State 1 at 3.0 Å,\r\n8\r\nState 2 at 3.1 Å, and State 3 at 3.2 Å, overall). We observed several new features in our maps;\r\nhowever, we cannot definitively determine the exact mechanism of yaku amide’s inhibition on\r\nthe protein due to either resolution limits or suboptimal binding of the inhibitor."}],"alternative_title":["ISTA Thesis"],"date_updated":"2026-10-16T08:50:36Z","degree_awarded":"PhD","article_processing_charge":"No","supplementarymaterial":"no","date_created":"2024-07-26T09:05:55Z","month":"07","page":"224","publication_status":"published","department":[{"_id":"LeSa"},{"_id":"GradSch"}],"language":[{"iso":"eng"}],"doi_confirm":"1","oa":1,"title":"Membrane proteins in plant physiology and bioenergetics : Investigating auxin efflux transporter PIN8 and ATP synthase inhibition by the novel inhibitor Yaku'amide B","publication_identifier":{"issn":["2663-337X"]},"type":"dissertation","doi":"10.15479/at:ista:17319","author":[{"orcid":"0000-0003-1581-881X","first_name":"Kristina","full_name":"Lukic, Kristina","id":"2B04DB84-F248-11E8-B48F-1D18A9856A87","last_name":"Lukic"}],"corr_author":"1"},{"ddc":["570"],"date_published":"2024-09-04T00:00:00Z","has_accepted_license":"1","article_type":"original","fulldoi":"https://doi.org/10.1038/s42003-024-06747-9","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"date_updated":"2026-10-26T23:31:05Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","file_date_updated":"2024-09-17T09:44:29Z","abstract":[{"lang":"eng","text":"The developmental plasticity of the root system plays an essential role in the adaptation of plants to the environment. Among many other signals, auxin and its directional, intercellular transport are critical in regulating root growth and development. In particular, the PIN-FORMED2 (PIN2) auxin exporter acts as a key regulator of root gravitropic growth. Multiple regulators have been reported to be involved in PIN2-mediated root growth; however, our information remains incomplete. Here, we identified ROWY Bro1-domain proteins as important regulators of PIN2 sorting control. Genetic analysis revealed that Arabidopsis rowy1 single mutants and higher-order rowy1 rowy2 rowy3 triple mutants presented a wavy root growth phenotype. Cell biological experiments revealed that ROWY1 and PIN2 colocalized to the apical side of the plasma membrane in the root epidermis and that ROWYs are required for correct PM targeting of PIN2. In addition, ROWYs also affected PIN3 protein abundance in the stele, suggesting the potential involvement of additional PIN transporters as well as other proteins. A global transcriptome analysis revealed that ROWY genes are involved in the Fe2+ availability perception pathway. This work establishes ROWYs as important novel regulators of root gravitropic growth by connecting micronutrient availability to the proper subcellular targeting of PIN auxin transporters."}],"dataavailabilitystatement":"The RNA-seq data for this study are available online at the NCBI Sequence Read Archive (accession number: PRJNA1116831).

Given the relatively sparse labeling, depending on which of the 19 MADM chromosomes one chooses, the MADM approach represents the perfect opportunity for cell morphology analysis. Various MADM studies include reports of morphological anomalies and phenotypes in the central nervous system (CNS). MADM for any candidate gene can easily incorporate morphological analysis within the experimental workflow. Here, we describe the methods of morphological cell analysis which we developed in the course of diverse recent MADM studies. This chapter will specifically focus on methods to quantify aspects of the morphology of neurons and astrocytes within the CNS, but these methods can broadly be applied to any MADM-labeled cells throughout the entire organism. We will cover two analyses—soma volume and dendrite characterization—of physical characteristics of pyramidal neurons in the somatosensory cortex, and two analyses—volume and Sholl analysis—of astrocyte morphology."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","article_processing_charge":"No","date_created":"2024-08-13T12:16:41Z","supplementarymaterial":"yes","quality_controlled":"1","related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"20212"}]},"place":"New York, NY","project":[{"name":"Molecular Mechanisms Regulating Cortical Neural Stem Cell Lineage Progression and Astrocyte Development","_id":"34c9fbcb-11ca-11ed-8bc3-98fa5658610d","grant_number":"26253"},{"_id":"059F6AB4-7A3F-11EA-A408-12923DDC885E","name":"Stem Cell Modulation in Neural Development and Regeneration/ P05-Molecular Mechanisms of Neural Stem Cell Lineage Progression","grant_number":"F7805"}],"publication_status":"published","department":[{"_id":"GradSch"},{"_id":"SiHi"}],"volume":2831,"language":[{"iso":"eng"}],"series_title":"MIMB","page":"283-299","month":"08","type":"book_chapter","doi":"10.1007/978-1-0716-3969-6_19","title":"Morphological Analysis of Neurons and Glia Using Mosaic Analysis with Double Markers","publication_identifier":{"issn":["1064-3745"],"eissn":["1940-6029"],"eisbn":["9781071639696"],"isbn":["9781071639689"]},"pmid":1,"scopus_import":"1","edition":"1","corr_author":"1","author":[{"id":"862A3C56-A8BF-11E9-B4FA-D9E3E5697425","last_name":"Miranda","full_name":"Miranda, Osvaldo","first_name":"Osvaldo","orcid":"0000-0001-6618-6889"},{"full_name":"Cheung, Giselle T","id":"471195F6-F248-11E8-B48F-1D18A9856A87","last_name":"Cheung","orcid":"0000-0001-8457-2572","first_name":"Giselle T"},{"first_name":"Simon","orcid":"0000-0003-2279-1061","id":"37B36620-F248-11E8-B48F-1D18A9856A87","last_name":"Hippenmeyer","full_name":"Hippenmeyer, Simon"}],"publication":"Neuronal Morphogenesis"},{"related_material":{"link":[{"url":"https://doi.org/10.1038/s41594-025-01721-3","relation":"erratum"}]},"quality_controlled":"1","project":[{"_id":"627abdeb-2b32-11ec-9570-ec31a97243d3","name":"Structure and mechanism of respiratory chain molecular machines","call_identifier":"H2020","grant_number":"101020697"}],"article_processing_charge":"No","supplementarymaterial":"yes","date_created":"2024-04-14T22:01:03Z","month":"07","publication_status":"published","department":[{"_id":"LeSa"}],"volume":31,"language":[{"iso":"eng"}],"page":"1061-1071","type":"journal_article","doi":"10.1038/s41594-024-01255-0","oa":1,"title":"SCAF1 drives the compositional diversity of mammalian respirasomes","pmid":1,"publication_identifier":{"issn":["1545-9993"],"eissn":["1545-9985"]},"author":[{"first_name":"Irene","orcid":"0000-0001-5618-3449","last_name":"Vercellino","id":"3ED6AF16-F248-11E8-B48F-1D18A9856A87","full_name":"Vercellino, Irene"},{"last_name":"Sazanov","id":"338D39FE-F248-11E8-B48F-1D18A9856A87","full_name":"Sazanov, Leonid A","first_name":"Leonid A","orcid":"0000-0002-0977-7989"}],"publication":"Nature Structural and Molecular Biology","scopus_import":"1","corr_author":"1","intvolume":"        31","file":[{"file_name":"megacomplex_submit_NSMB_withFigures.pdf","date_created":"2024-05-14T11:57:56Z","file_size":24424729,"embargo":"2025-01-01","file_id":"15392","date_updated":"2025-01-01T23:30:03Z","content_type":"application/pdf","creator":"lsazanov","relation":"main_file","checksum":"21f05d188762acd7f49a97f3d09c8d9f","access_level":"open_access"}],"external_id":{"pmid":["38575788"],"isi":["001196897300001"]},"dataavailabilitystatement":"Structures of the three SCs were deposited in PDB (accessions 8PW5, 8PW6 and 8PW7) with corresponding cryo-EM density maps in EMDB (IDs 17989, 17990 and 17991).

Although many genetic interactions involved in the establishment of morphogen production domains are known, the biophysical mechanisms of morphogen source formation are poorly understood. Here we addressed this by focusing on the morphogen Sonic hedgehog (Shh) in the vertebrate neural tube. Shh is produced by the adjacently located notochord and by the floor plate of the neural tube. Using a data-constrained computational screen, we identified different possible mechanisms by which floor plate formation can occur, only one of which is consistent with experimental data. In this mechanism, the floor plate is established rapidly in response to Shh from the notochord and the dynamics of regulatory interactions within the neural tube. In this process, uniform activators and Shh-dependent repressors are key for establishing the floor plate size. Subsequently, the floor plate becomes insensitive to Shh and increases in size due to tissue growth, leading to scaling of the floor plate with neural tube size. In turn, this results in scaling of the Shh amplitude with tissue growth. Thus, this mechanism ensures a separation of time scales in floor plate formation, so that the floor plate domain becomes growth-dependent after an initial rapid establishment phase. Our study raises the possibility that the time scale separation between specification and growth might be a common strategy for scaling the morphogen gradient amplitude in growing organs. The model that we developed provides a new opportunity for quantitative studies of morphogen source formation in growing tissues.","lang":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_updated":"2026-10-26T23:31:07Z","DOAJ_listed":"1","OA_place":"publisher","tmp":{"image":"/images/cc_by.png","short":"CC

development, the notochord induces an organizer, the floorplate, which secretes Sonic Hedgehog (SHH) to pattern neural progenitors. Conversely, NT organoids (NTOs) from embryonic stem cells (ESCs) spontaneously form floorplates without the notochord, demonstrating that stem cells can self-organize without embryonic inducers. Here, we investigated floorplate self-organization in clonal mouse NTOs. Expression of the floorplate marker FOXA2 was initially spatially scattered before resolving into multiple clusters, which underwent competition and sorting, resulting in a stable “winning” floorplate. We identified that BMP signaling governed long-range cluster competition. FOXA2+ clusters expressed BMP4, suppressing FOXA2 in receiving cells while simultaneously expressing the BMP-inhibitor NOGGIN, promoting cluster persistence. Noggin mutation perturbed floorplate formation in NTOs and in the NT in vivo at mid/hindbrain regions, demonstrating how the floorplate can form autonomously without the notochord. Identifying the pathways governing organizer self-organization is critical for harnessing the developmental plasticity of stem cells in tissue engineering."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","fulldoi":"https://doi.org/10.1016/j.devcel.2024.04.021","article_type":"original","tmp":{"image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"ddc":["570"],"date_published":"2024-08-01T00:00:00Z","OA_type":"hybrid","has_accepted_license":"1","OA_place":"publisher","oa_version":"Published Version","researchdata_availability":"yes","_id":"17148","status":"public","year":"2024","acknowledgement":"We thank P.

We explore in simulation how well the method\r\ncan fine-map genetic effects, find the correct causal structure among tens of traits and\r\nmillions of genetic markers, and infer the causal effect size for the discovered causal\r\nrelations. We then apply the method to 8 million markers and 17 traits from the UK\r\nBiobank and show that many relationships found with other methods are likely due to\r\nthe effects of hidden confounders.\r\nChapter 3 describes how this method can be applied to longitudinal data. I show how one\r\ncan incorporate the background knowledge present in the known order of measurements to\r\nimprove the accuracy of the causal discovery process, and explore the method’s ability to\r\nidentify age specific genetic effects, and how the error rates of this recovery are influenced\r\nby missing data due to different censoring mechanisms.\r\nChapter 4 introduces a statistical software for the comparison of chromatin contact maps\r\nbased on the structural similarity index. We explore the robustness of the method to\r\nnoise and size differences of the compared maps, show how it can measure evolutionary\r\nconservation of topological features by providing a similarity ranking of syntenic regions,\r\nand finally how it can detect alterations in 3D genome structure due to genetic mutations\r\nin samples of medical relevance.\r\n"}],"file_date_updated":"2025-06-12T22:30:02Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","fulldoi":"https://doi.org/10.15479/at:ista:18642","has_accepted_license":"1","date_published":"2024-12-11T00:00:00Z","ddc":["576"],"OA_place":"publisher","publication_status":"published","language":[{"iso":"eng"}],"department":[{"_id":"GradSch"},{"_id":"MaRo"}],"page":"138","month":"12","article_processing_charge":"No","date_created":"2024-12-10T13:49:15Z","supplementarymaterial":"unclear","related_material":{"record":[{"status":"public","id":"8707","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","id":"18648","status":"public"}]},"project":[{"name":"Improving estimation and prediction of common complex disease risk","_id":"9B8D11D6-BA93-11EA-9121-9846C619BF3A","grant_number":"PCEGP3_181181"}],"degree_awarded":"PhD","corr_author":"1","author":[{"full_name":"Machnik, Nick N","id":"3591A0AA-F248-11E8-B48F-1D18A9856A87","last_name":"Machnik","first_name":"Nick N","orcid":"0000-0001-6617-9742"}],"type":"dissertation","doi":"10.15479/at:ista:18642","title":"Algorithms for causal learning and comparative analysis for genomic data","oa":1,"publication_identifier":{"issn":["2663-337X"]},"doi_confirm":"1"},{"month":"12","publication_status":"published","department":[{"_id":"AnKi"},{"_id":"NanoFab"}],"volume":5,"language":[{"iso":"eng"}],"project":[{"name":"Mechanisms of tissue size regulation in spinal cord development","_id":"bd7e737f-d553-11ed-ba76-d69ffb5ee3aa","grant_number":"101044579"},{"grant_number":"SC19-011","name":"The regulatory logic of pattern formation in the vertebrate dorsal neural tube","_id":"9B9B39FA-BA93-11EA-9121-9846C619BF3A"}],"quality_controlled":"1","related_material":{"record":[{"status":"public","id":"19763","relation":"dissertation_contains"}]},"APC_amount":"804 EUR","article_processing_charge":"Yes","date_created":"2024-12-01T23:01:53Z","supplementarymaterial":"no","publication":"STAR Protocols","author":[{"orcid":"0000-0001-8703-1093","first_name":"Stefanie","id":"4D9EC9B6-F248-11E8-B48F-1D18A9856A87","last_name":"Rus","full_name":"Rus, Stefanie"},{"first_name":"Jack","orcid":"0000-0001-5145-4609","id":"4515C308-F248-11E8-B48F-1D18A9856A87","last_name":"Merrin","full_name":"Merrin, Jack"},{"full_name":"Kulig, Monika Aleksandra","id":"3331f5ae-e896-11ec-af79-eeb79769bcb7","last_name":"Kulig","first_name":"Monika Aleksandra"},{"first_name":"Thomas","id":"7d1648cb-19e9-11eb-8e7a-f8c037fb3e3f","last_name":"Minchington","full_name":"Minchington, Thomas"},{"first_name":"Anna","orcid":"0000-0003-4509-4998","last_name":"Kicheva","id":"3959A2A0-F248-11E8-B48F-1D18A9856A87","full_name":"Kicheva, Anna"}],"corr_author":"1","scopus_import":"1","article_number":"103187","title":"Protocol for fabricating elastomeric stencils for patterned stem cell differentiation","oa":1,"publication_identifier":{"eissn":["2666-1667"]},"pmid":1,"type":"journal_article","doi":"10.1016/j.xpro.2024.103187","day":"20","das_tickbox":"1","publisher":"Elsevier","year":"2024","citation":{"mla":"Rus, Stefanie, et al. “Protocol for Fabricating Elastomeric Stencils for Patterned Stem Cell Differentiation.” <i>STAR Protocols</i>, vol. 5, no. 4, 103187, Elsevier, 2024, doi:<a href=\"https://doi.org/10.1016/j.xpro.2024.103187\">10.1016/j.xpro.2024.103187</a>.","short":"S.

receptor (GBR) activation inhibits neurotransmitter release in axon terminals in the brain, except in medial habenula (MHb) terminals, which show robust potentiation. However, mechanisms underlying this enigmatic potentiation remain elusive. Here, we report that GBR activation on MHb terminals induces an activity-dependent transition from a facilitating, tonic to a depressing, phasic neurotransmitter release mode. This transition is accompanied by a 4.1-fold increase in readily releasable vesicle pool (RRP) size and a 3.5-fold increase of docked synaptic vesicles (SVs) at the presynaptic active zone (AZ). Strikingly, the depressing phasic release exhibits looser coupling distance than the tonic release. Furthermore, the tonic and phasic release are selectively affected by deletion of synaptoporin (SPO) and Ca\r\n            <jats:sup>2+</jats:sup>\r\n            -dependent activator protein for secretion 2 (CAPS2), respectively. SPO modulates augmentation, the short-term plasticity associated with tonic release, and CAPS2 retains the increased RRP for initial responses in phasic response trains. The cytosolic protein CAPS2 showed a SV-associated distribution similar to the vesicular transmembrane protein SPO, and they were colocalized in the same terminals. We developed the “Flash and Freeze-fracture” method, and revealed the release of SPO-associated vesicles in both tonic and phasic modes and activity-dependent recruitment of CAPS2 to the AZ during phasic release, which lasted several minutes. Overall, these results indicate that GBR activation translocates CAPS2 to the AZ along with the fusion of CAPS2-associated SVs, contributing to persistency of the RRP increase. Thus, we identified structural and molecular mechanisms underlying tonic and phasic neurotransmitter release and their transition by GBR activation in MHb terminals."}],"ddc":["570"],"date_published":"2024-02-20T00:00:00Z","OA_type":"hybrid","has_accepted_license":"1","fulldoi":"https://doi.org/10.1073/pnas.2301449121","article_type":"original","tmp":{"image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"OA_place":"publisher","_id":"15084","researchdata_availability":"yes","status":"public","oa_version":"Published Version","das_tickbox":"1","day":"20","isi":1,"year":"2024","acknowledgement":"We thank Erwin Neher and Ipe Ninan for critical comments on the manuscript.

It summarizes a spectrum of neurological\r\ndisorders that have in common a hyperactivity of the neuronal network resulting in seizures. A common\r\nassumption is that an imbalance between neuronal excitation and inhibition is a key mechanism in\r\nseizure generation and epileptogeneisis. In at least one-third of the patients, current therapies have\r\nproven unsuccessful in treating seizure progression. One potential reason could be that the therapies\r\nonly focus on neurons. Recent studies suggest that neuronal hyperactivity causes a microglial\r\nresponse, which reinstates brain homeostasis. Additionally, interactions between microglia and neurons\r\nhave been shown to inhibit neuronal firing and dampen seizure activity. However, the exact relationship\r\nbetween microglia and seizure progression in epilepsy is yet to be elucidated. A main bottleneck is that\r\nseveral studies investigate microglia dynamics in ex vivo slice models, which can severely affect the\r\nmicroglia dynamics due to their rapid response to environmental changes. On the other hand, in vivo\r\nstudies focus mostly on behavior characterization of the epileptic seizure phenotype and their long-term\r\nconsequences on microglia activity leaving out the direct consequences of acute seizure activity on\r\nmicroglia dynamics.\r\nHere, we perform a pilot study to combine electroencephalography (EEG) and in vivo live imaging to\r\ndirectly monitor and correlate the onset of seizure activity with microglia response. To induce seizures,\r\nwe take advantage of the kainic acid (KA) model, which represents similar neuropathological and\r\nelectroencephalographic features seen in human patients with temporal lobe epilepsy (TLE). After\r\nconfirmation of induction of the seizure and microglia activity in the hippocampus as a focal point, we\r\ninvestigated whether these changes also reached the primary visual cortex (V1) as a secondary\r\ngeneralized seizure activity. Indeed, we found that microglia changed their morphology at high doses\r\nof KA in the V1. Next, we optimized each of the two methodological components: for the EEG recording,\r\nour initial attempts under the microscope suffered from extensive electrical noise, which overlaid the\r\nactual signal. Thus, we built a customized Faraday-cage and confirmed that the signal-to-noise ratio\r\nwas sufficiently reduced to be able to record brain oscillatory activity. For the in vivo live imaging of\r\nmicroglia, we had to optimize the imaging parameters, so that we would be able to detect microglial\r\nprocesses in a sufficient resolution to track their process changes. Finally, we combined both\r\nmethodologies with the KA model. We confirmed that KA induced seizure activity and found first\r\nindication that those correlate with microglia volume changes.\r\nOverall, we have developed a first methodological approach, which allows the analysis of the acute\r\neffects of seizure onset on microglia. Future studies will have to continue to optimize the drift during\r\nimaging recording and the post-image analysis.

A recent transition from egg-laying to live-bearing in marine snails (Littorina spp.) provides the opportunity to study the genetic architecture of an innovation that has evolved repeatedly across animals. Individuals do not cluster by reproductive mode in a genome-wide phylogeny, but local genealogical analysis revealed numerous small genomic regions where all live-bearers carry the same core haplotype. Candidate regions show evidence for live-bearer–specific positive selection and are enriched for genes that are differentially expressed between egg-laying and live-bearing reproductive systems. Ages of selective sweeps suggest that live-bearer–specific alleles accumulated over more than 200,000 generations.
