Microglia rely on mitochondria to respond to these stressors, however our knowledge about mitochondrial networks and their adaptations in microglia in vivo is limited. Here, we generate a mouse model that selectively labels mitochondria in microglia. We identify that mitochondrial networks are more fragmented with increased content and perinuclear localization in vitro vs. in vivo. Mitochondrial networks adapt similarly in microglia closest to the injury site after optic nerve crush. Preventing microglial UCP2 increase after injury by selective knockout induces cellular stress. This results in mitochondrial hyperfusion in male microglia, a phenotype absent in females due to circulating estrogens. Our results establish the foundation for mitochondrial network analysis of microglia in vivo, emphasizing the importance of mitochondrial-based sex effects of microglia in other pathologies.","lang":"eng"}],"oa_version":"Published Version","pmid":1,"scopus_import":"1","month":"10","intvolume":" 26","publication_identifier":{"eissn":["2589-0042"]},"publication_status":"published","file":[{"file_size":8197935,"date_updated":"2023-11-07T08:53:21Z","creator":"dernst","file_name":"2023_iScience_Maes.pdf","date_created":"2023-11-07T08:53:21Z","content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"checksum":"be1a560efdd96d20712311f4fc54aac2","file_id":"14497"}],"language":[{"iso":"eng"}],"volume":26,"issue":"10","license":"https://creativecommons.org/licenses/by/4.0/"},{"project":[{"grant_number":"I03600","name":"Optical control of synaptic function via adhesion molecules","call_identifier":"FWF","_id":"265CB4D0-B435-11E9-9278-68D0E5697425"},{"grant_number":"W1232-B24","name":"Molecular Drug Targets","call_identifier":"FWF","_id":"2548AE96-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","_id":"25C5A090-B435-11E9-9278-68D0E5697425","grant_number":"Z00312","name":"The Wittgenstein Prize"},{"name":"High content imaging to decode human immune cell interactions in health and allergic disease","_id":"23889792-32DE-11EA-91FC-C7463DDC885E"},{"name":"Probing the Reversibility of Autism Spectrum Disorders by Employing in vivo and in vitro Models","grant_number":"715508","call_identifier":"H2020","_id":"25444568-B435-11E9-9278-68D0E5697425"},{"grant_number":"692692","name":"Biophysics and circuit function of a giant cortical glumatergic synapse","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","grant_number":"665385"},{"grant_number":"101026635","name":"Synaptic computations of the hippocampal CA3 circuitry","call_identifier":"H2020","_id":"fc2be41b-9c52-11eb-aca3-faa90aa144e9"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"J.M.

Super-resolution optical microscopy excels at visualizing specific molecules and individual cells but fails to provide tissue context. Here we developed Comprehensive Analysis of Tissues across Scales (CATS), a technology to densely map brain tissue architecture from millimeter regional to nanometer synaptic scales in diverse chemically fixed brain preparations, including rodent and human. CATS uses fixation-compatible extracellular labeling and optical imaging, including stimulated emission depletion or expansion microscopy, to comprehensively delineate cellular structures. It enables three-dimensional reconstruction of single synapses and mapping of synaptic connectivity by identification and analysis of putative synaptic cleft regions. Applying CATS to the mouse hippocampal mossy fiber circuitry, we reconstructed and quantified the synaptic input and output structure of identified neurons. We furthermore demonstrate applicability to clinically derived human tissue samples, including formalin-fixed paraffin-embedded routine diagnostic specimens, for visualizing the cellular architecture of brain tissue in health and disease."}],"month":"08","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41587-023-01911-8"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"epub_ahead","publication_identifier":{"eissn":["1546-1696"],"issn":["1087-0156"]},"ec_funded":1,"related_material":{"link":[{"url":"https://github.com/danzllab/CATS","relation":"software"}],"record":[{"relation":"research_data","id":"13126","status":"public"}]}},{"date_created":"2022-07-03T22:01:33Z","doi":"10.1016/j.isci.2022.104580","date_published":"2022-07-15T00:00:00Z","year":"2022","has_accepted_license":"1","isi":1,"publication":"iScience","day":"15","oa":1,"quality_controlled":"1","publisher":"Elsevier","acknowledgement":"We thank the scientific service units at ISTA, specifically the lab support facility and imaging & optics facility for their support; Nicolas Armel for performing the Mass Spectrometry.

However, organoids usually lack microglia, brain-resident immune cells, which are present in the early embryonic brain and participate in neuronal circuit development. Here, we find IBA1+ microglia-like cells alongside retinal cups between week 3 and 4 in 2.5D culture with an unguided retinal organoid differentiation protocol. Microglia do not infiltrate the neuroectoderm and instead enrich within non-pigmented, 3D-cystic compartments that develop in parallel to the 3D-retinal organoids. When we guide the retinal organoid differentiation with low-dosed BMP4, we prevent cup development and enhance microglia and 3D-cysts formation. Mass spectrometry identifies these 3D-cysts to express mesenchymal and epithelial markers. We confirmed this microglia-preferred environment also within the unguided protocol, providing insight into microglial behavior and migration and offer a model to study how they enter and distribute within the human brain.","lang":"eng"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"oa_version":"Published Version","department":[{"_id":"SaSi"}],"file_date_updated":"2022-07-04T08:19:25Z","date_updated":"2023-11-02T12:21:33Z","ddc":["610"],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"journal_article","article_type":"original","status":"public","_id":"11478"},{"date_updated":"2023-11-02T12:21:32Z","ddc":["570"],"file_date_updated":"2023-01-23T09:50:51Z","department":[{"_id":"SaSi"},{"_id":"GradSch"}],"_id":"12117","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"},"type":"journal_article","article_type":"letter_note","keyword":["General Immunology and Microbiology","General Biochemistry","Genetics and Molecular Biology","General Neuroscience"],"status":"public","publication_status":"published","publication_identifier":{"issn":["2666-1667"]},"language":[{"iso":"eng"}],"file":[{"date_created":"2023-01-23T09:50:51Z","file_name":"2022_STARProtocols_Huebschmann.pdf","date_updated":"2023-01-23T09:50:51Z","file_size":6251945,"creator":"dernst","file_id":"12340","checksum":"3c71b8a60633d42c2f77c49025d5559b","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"ec_funded":1,"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","volume":3,"issue":"4","related_material":{"record":[{"relation":"other","id":"11478","status":"public"}]},"abstract":[{"lang":"eng","text":"To understand how potential gene manipulations affect in vitro microglia, we provide a set of short protocols to evaluate microglia identity and function.

However, ligands for many GPCRs remain unknown, suffer from off-target effects or have poor bioavailability. Additionally, dissecting cell type-specific responses is challenging when the same GPCR is expressed on different cells within a tissue. Here, we overcome these limitations by engineering DREADD-based GPCR chimeras that bind clozapine-N-oxide and mimic a GPCR-of-interest. We show that chimeric DREADD-β2AR triggers responses comparable to β2AR on second messenger and kinase activity, post-translational modifications, and protein-protein interactions. Moreover, we successfully recapitulate β2AR-mediated filopodia formation in microglia, an immune cell capable of driving central nervous system inflammation. When dissecting microglial inflammation, we included two additional DREADD-based chimeras mimicking microglia-enriched GPR65 and GPR109A. DREADD-β2AR and DREADD-GPR65 modulate the inflammatory response with high similarity to endogenous β2AR, while DREADD-GPR109A shows no impact. Our DREADD-based approach allows investigation of cell type-dependent pathways without known endogenous ligands.","lang":"eng"}],"department":[{"_id":"SaSi"}],"file_date_updated":"2022-08-29T06:44:30Z","ddc":["570"],"date_updated":"2024-02-21T12:34:51Z","status":"public","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"11995","doi":"10.1038/s41467-022-32390-1","date_published":"2022-08-15T00:00:00Z","date_created":"2022-08-28T22:01:59Z","day":"15","publication":"Nature Communications","has_accepted_license":"1","isi":1,"year":"2022","publisher":"Springer Nature","quality_controlled":"1","oa":1,"acknowledgement":"The authors thank the Scientific Service Units at ISTA, in particular the Molecular Biology Service of the Lab Support Facility, Imaging & Optics Facility, and the Preclinical Facility, and the Novarino group, Harald Janoviak, and Marco Benevento for sharing reagents and expertise.

Strategies to characterize these changes usually involve user-selected morphometric features, which preclude the identification of a spectrum of context-dependent morphological phenotypes. Here we develop MorphOMICs, a topological data analysis approach, which enables semiautomatic mapping of microglial morphology into an atlas of cue-dependent phenotypes and overcomes feature-selection biases and biological variability. We extract spatially heterogeneous and sexually dimorphic morphological phenotypes for seven adult mouse brain regions. This sex-specific phenotype declines with maturation but increases over the disease trajectories in two neurodegeneration mouse models, with females showing a faster morphological shift in affected brain regions. Remarkably, microglia morphologies reflect an adaptation upon repeated exposure to ketamine anesthesia and do not recover to control morphologies. Finally, we demonstrate that both long primary processes and short terminal processes provide distinct insights to morphological phenotypes. MorphOMICs opens a new perspective to characterize microglial morphology."}],"acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"},{"_id":"ScienComp"}],"oa_version":"Published Version","pmid":1,"file_date_updated":"2023-01-30T08:06:56Z","department":[{"_id":"SaSi"}],"date_updated":"2024-03-27T23:30:17Z","ddc":["570"],"article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","keyword":["General Neuroscience"],"_id":"12244","page":"1379-1393","date_published":"2022-10-01T00:00:00Z","doi":"10.1038/s41593-022-01167-6","date_created":"2023-01-16T09:53:07Z","isi":1,"has_accepted_license":"1","year":"2022","day":"01","publication":"Nature Neuroscience","publisher":"Springer Nature","quality_controlled":"1","oa":1,"acknowledgement":"We thank the scientific service units at ISTA, in particular M.

Here we developed Comprehensive Analysis of Tissues across Scales (CATS), a technology to densely map brain tissue architecture from millimeter regional to nanoscopic synaptic scales in diverse chemically fixed brain preparations, including rodent and human. CATS leverages fixation-compatible extracellular labeling and advanced optical readout, in particular stimulated-emission depletion and expansion microscopy, to comprehensively delineate cellular structures. It enables 3D-reconstructing single synapses and mapping synaptic connectivity by identification and tailored analysis of putative synaptic cleft regions. Applying CATS to the hippocampal mossy fiber circuitry, we demonstrate its power to reveal the system’s molecularly informed ultrastructure across spatial scales and assess local connectivity by reconstructing and quantifying the synaptic input and output structure of identified neurons."}],"oa_version":"Preprint","date_created":"2022-08-24T08:24:52Z","doi":"10.1101/2022.08.17.504272","date_published":"2022-08-18T00:00:00Z","related_material":{"record":[{"status":"public","id":"12470","relation":"dissertation_contains"}]},"year":"2022","publication_status":"submitted","language":[{"iso":"eng"}],"publication":"bioRxiv","day":"18"},{"author":[{"last_name":"Venturino","full_name":"Venturino, Alessandro","orcid":"0000-0003-2356-9403","first_name":"Alessandro","id":"41CB84B2-F248-11E8-B48F-1D18A9856A87"},{"id":"4C5E7B96-F248-11E8-B48F-1D18A9856A87","first_name":"Rouven","last_name":"Schulz","orcid":"0000-0001-5297-733X","full_name":"Schulz, Rouven"},{"full_name":"De Jesús-Cortés, Héctor","last_name":"De Jesús-Cortés","first_name":"Héctor"},{"orcid":"0000-0001-9642-1085","full_name":"Maes, Margaret E","last_name":"Maes","first_name":"Margaret E","id":"3838F452-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Balint","id":"93C65ECC-A6F2-11E9-8DF9-9712E6697425","last_name":"Nagy","full_name":"Nagy, Balint"},{"full_name":"Reilly-Andújar, Francis","last_name":"Reilly-Andújar","first_name":"Francis"},{"first_name":"Gloria","id":"3483CF6C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9434-8902","full_name":"Colombo, Gloria","last_name":"Colombo"},{"orcid":"0000-0003-0002-1867","full_name":"Cubero, Ryan J","last_name":"Cubero","id":"850B2E12-9CD4-11E9-837F-E719E6697425","first_name":"Ryan J"},{"first_name":"Florianne E","id":"3526230C-F248-11E8-B48F-1D18A9856A87","last_name":"Schoot Uiterkamp","full_name":"Schoot Uiterkamp, Florianne E"},{"last_name":"Bear","full_name":"Bear, Mark F.","first_name":"Mark F."},{"id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","first_name":"Sandra","last_name":"Siegert","full_name":"Siegert, Sandra","orcid":"0000-0001-8635-0877"}],"article_processing_charge":"No","external_id":{"isi":["000670188500004"],"pmid":["34233180"]},"title":"Microglia enable mature perineuronal nets disassembly upon anesthetic ketamine exposure or 60-Hz light entrainment in the healthy brain","citation":{"ista":"Venturino A, Schulz R, De Jesús-Cortés H, Maes ME, Nagy B, Reilly-Andújar F, Colombo G, Cubero RJ, Schoot Uiterkamp FE, Bear MF, Siegert S. 2021.

Current strategies to remove PNN are long-lasting, invasive, and trigger neuropsychiatric symptoms. Here, we apply repeated anesthetic ketamine as a method with minimal behavioral effect. We find that this paradigm strongly reduces PNN coating in the healthy adult brain and promotes juvenile-like plasticity. Microglia are critically involved in PNN loss because they engage with parvalbumin-positive neurons in their defined cortical layer. We identify external 60-Hz light-flickering entrainment to recapitulate microglia-mediated PNN removal. Importantly, 40-Hz frequency, which is known to remove amyloid plaques, does not induce PNN loss, suggesting microglia might functionally tune to distinct brain frequencies. Thus, our 60-Hz light-entrainment strategy provides an alternative form of PNN intervention in the healthy adult brain."}],"pmid":1,"oa_version":"Published Version"},{"file":[{"success":1,"file_id":"10657","checksum":"77dc540e8011c5475031bdf6ccef20a6","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2021_MolTherMethodsClinDev_Maes.pdf","date_created":"2022-01-24T07:43:09Z","file_size":4794147,"date_updated":"2022-01-24T07:43:09Z","creator":"cchlebak"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2329-0501"]},"publication_status":"published","volume":23,"ec_funded":1,"oa_version":"Published Version","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"PreCl"}],"abstract":[{"text":"Adeno-associated viruses (AAVs) are widely used to deliver genetic material in vivo to distinct cell types such as neurons or glial cells, allowing for targeted manipulation. Transduction of microglia is mostly excluded from this strategy, likely due to the cells’ heterogeneous state upon environmental changes, which makes AAV design challenging. Here, we established the retina as a model system for microglial AAV validation and optimization. First, we show that AAV2/6 transduced microglia in both synaptic layers, where layer preference corresponds to the intravitreal or subretinal delivery method. Surprisingly, we observed significantly enhanced microglial transduction during photoreceptor degeneration. Thus, we modified the AAV6 capsid to reduce heparin binding by introducing four point mutations (K531E, R576Q, K493S, and K459S), resulting in increased microglial transduction in the outer plexiform layer. Finally, to improve microglial-specific transduction, we validated a Cre-dependent transgene delivery cassette for use in combination with the Cx3cr1CreERT2 mouse line. Together, our results provide a foundation for future studies optimizing AAV-mediated microglia transduction and highlight that environmental conditions influence microglial transduction efficiency.\r\n","lang":"eng"}],"month":"12","intvolume":" 23","scopus_import":"1","ddc":["570"],"date_updated":"2023-11-16T13:12:03Z","department":[{"_id":"SaSi"},{"_id":"SiHi"}],"file_date_updated":"2022-01-24T07:43:09Z","_id":"10655","status":"public","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"day":"10","publication":"Molecular Therapy - Methods and Clinical Development","isi":1,"has_accepted_license":"1","year":"2021","date_published":"2021-12-10T00:00:00Z","doi":"10.1016/j.omtm.2021.09.006","date_created":"2022-01-23T23:01:28Z","page":"210-224","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement no. 715571).

The iPS-derived and differentiated cells allow researchers to study the impact of a distinct cell type in health and disease as well as performing therapeutic drug screens on a human genetic background. In particular, clinical trials for Alzheimer's disease (AD) have been often failing. Two of the potential reasons are first, the species gap involved in proceeding from initial discoveries in rodent models to human studies, and second, an unsatisfying patient stratification, meaning subgrouping patients based on the disease severity due to the lack of phenotypic and genetic markers. iPS cells overcome this obstacles and will improve our understanding of disease subtypes in AD. They allow researchers conducting in depth characterization of neural cells from both familial and sporadic AD patients as well as preclinical screens on human cells.\r\n\r\nIn this review, we briefly outline the status quo of iPS cell research in neurological diseases along with the general advantages and pitfalls of these models. We summarize how genome-editing techniques such as CRISPR/Cas will allow researchers to reduce the problem of genomic variability inherent to human studies, followed by recent iPS cell studies relevant to AD. We then focus on current techniques for the differentiation of iPS cells into neural cell types that are relevant to AD research. Finally, we discuss how the generation of three-dimensional cell culture systems will be important for understanding AD phenotypes in a complex cellular milieu, and how both two- and three-dimensional iPS cell models can provide platforms for drug discovery and translational studies into the treatment of AD.","lang":"eng"}],"oa_version":"Submitted Version"},{"oa":1,"publisher":"American Medical Association","quality_controlled":"1","date_created":"2018-12-11T11:50:58Z","doi":"10.1001/jamapsychiatry.2015.3144","date_published":"2016-04-01T00:00:00Z","page":"409 - 410","publication":"JAMA Psychiatry","day":"01","year":"2016","has_accepted_license":"1","title":"How MicroRNAs Are involved in splitting the mind","article_processing_charge":"No","external_id":{"pmid":["26963490"]},"author":[{"full_name":"Tsai, Lihuei","last_name":"Tsai","first_name":"Lihuei"},{"orcid":"0000-0001-8635-0877","full_name":"Siegert, Sandra","last_name":"Siegert","id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","first_name":"Sandra"}],"publist_id":"6074","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Tsai L, Siegert S. 2016.

A combination of optogenetic and pharmacosynthetic approaches shows that BLA activation is both necessary and sufficient for stress-associated molecular changes and memory impairments. Furthermore, we show that this effect relies on direct glutamatergic projections from the BLA to the dorsal hippocampus. Finally, we show that p25 generation is necessary for the stress-induced memory dysfunction.

We observed increased MIR137 levels compared to those in major allele–carrying cells. microRNA-137 gain of function caused downregulation of the presynaptic target genes complexin-1 (Cplx1), Nsf and synaptotagmin-1 (Syt1), leading to impaired vesicle release. In vivo, miR-137 gain of function resulted in changes in synaptic vesicle pool distribution, impaired induction of mossy fiber long-term potentiation and deficits in hippocampus-dependent learning and memory. By sequestering endogenous miR-137, we were able to ameliorate the synaptic phenotypes. Moreover, reinstatement of Syt1 expression partially restored synaptic plasticity, demonstrating the importance of Syt1 as a miR-137 target.

We found that each adult cell type expressed a specific set of genes, including a unique set of transcription factors, forming a 'barcode' for cell identity. Cell type transcriptomes carried enough information to categorize cells into morphological classes and types. Several genes that were specifically expressed in particular retinal circuit elements, such as inhibitory neuron types, are associated with eye diseases. The resource described here allows gene expression to be compared across adult retinal cell types, experimenting with specific transcription factors to differentiate stem or somatic cells to retinal cell types, and predicting cellular targets of newly discovered disease-associated genes.","lang":"eng"}],"acknowledgement":"The study was supported by Friedrich Miescher Institute funds, Alcon award, a National Center of Competence in Research Genetics grant, a European Research Council grant, a Swiss-Hungarian grant, and RETICIRC, TREATRUSH, SEEBETTER and OPTONEURO grants from the European Union to B.R."},{"date_updated":"2021-01-12T06:53:17Z","citation":{"ama":"Busskamp V, Duebel J, Bálya D, et al.

As a common pathology, rod photoreceptors die early, whereas light-insensitive, morphologically altered cone photoreceptors persist longer. It is unknown if these cones are accessible for therapeutic intervention. Here, we show that expression of archaebacterial halorhodopsin in light-insensitive cones can substitute for the native phototransduction cascade and restore light sensitivity in mouse models of retinitis pigmentosa. Resensitized photoreceptors activate all retinal cone pathways, drive sophisticated retinal circuit functions (including directional selectivity), activate cortical circuits, and mediate visually guided behaviors. Using human ex vivo retinas, we show that halorhodopsin can reactivate light-insensitive human photoreceptors. Finally, we identified blind patients with persisting, light-insensitive cones for potential halorhodopsin-based therapy.","lang":"eng"}],"acknowledgement":"This study was supported by Friedrich Miescher Institute funds; a U.S. Office of Naval Research Naval International Cooperative Opportunities in Science and Technology Program grant; a Marie Curie Excellence grant and a European Union (EU) HEALTH-F2-223156 grant to B.R.; a grant from the EU (RETICIRC) to B.R. and S.P.; grants from the Agence nationale de la recherche (MEDINAS, RETINE) to S.P.; a Center Grant from Foundation Fighting Blindness (U.S.) to S.M.-S. and J.A.S.; grants from the Swiss National Science Foundation and the EU to D.T.; a grant from the EU (TREATRUSH) to J.A.S., S.P., and B.R.; a Marie Curie Postdoctoral Fellowship to D.B.; and a National Centers of Competence in Research Frontiers in Genetics fellowship to V.B. and A.C.G.

We identify an approach-sensitive ganglion cell type in the mouse retina, resolve elements of its afferent neural circuit, and describe how these confer approach sensitivity on the ganglion cell. The circuit's essential building block is a rapid inhibitory pathway: it selectively suppresses responses to non-approaching objects. This rapid inhibitory pathway, which includes AII amacrine cells connected to bipolar cells through electrical synapses, was previously described in the context of night-time vision. In the daytime conditions of our experiments, the same pathway conveys signals in the reverse direction.

Bartha-strain derivatives spread only in the retrograde direction [13]. There is evidence that infected cells function normally for a while during GFP expression [7]. Here we combine transsynaptic PRV labeling, two-photon laser microscopy, and electrophysiological techniques to trace the local circuit of different ipRGC subtypes in the mouse retina and record light-evoked activity from the transsynaptically labeled ganglion cells. First, we show that ipRGCs are connected by monostratified amacrine cells that provide strong inhibition from classical-photoreceptor-driven circuits.
