Isolated SVs from neurons that have been genetically engineered, e.g. to introduce genetically encoded indicators, are not readily available but would permit new insights into SV structure and function. Furthermore, it is unclear if cultured neurons can provide sufficient starting material for SV isolation procedures.\r\n\r\nNew method\r\nHere, we demonstrate an efficient ex vivo procedure to obtain functional SVs from cultured rat cortical neurons after genetic engineering with a lentivirus.\r\n\r\nResults\r\nWe show that ∼108 plated cortical neurons allow isolation of suitable SV amounts for functional analysis and imaging. We found that SVs isolated from cultured neurons have neurotransmitter uptake comparable to that of SVs isolated from intact cortex. Using total internal reflection fluorescence (TIRF) microscopy, we visualized an exogenous SV-targeted marker protein and demonstrated the high efficiency of SV modification.\r\n\r\nComparison with existing methods\r\nObtaining SVs from genetically engineered neurons currently generally requires the availability of transgenic animals, which is constrained by technical (e.g. cost and time) and biological (e.g. developmental defects and lethality) limitations.\r\n\r\nConclusions\r\nThese results demonstrate the modification and isolation of functional SVs using cultured neurons and viral transduction. The ability to readily obtain SVs from genetically engineered neurons will permit linking in situ studies to in vitro experiments in a variety of genetic contexts.","lang":"eng"}],"publication":"Journal of Neuroscience Methods","department":[{"_id":"HaJa"},{"_id":"Bio"}],"status":"public","project":[{"grant_number":"303564","_id":"25548C20-B435-11E9-9278-68D0E5697425","name":"Microbial Ion Channels for Synthetic Neurobiology","call_identifier":"FP7"},{"_id":"26538374-B435-11E9-9278-68D0E5697425","grant_number":"I03630","call_identifier":"FWF","name":"Molecular mechanisms of endocytic cargo recognition in plants"},{"_id":"2548AE96-B435-11E9-9278-68D0E5697425","grant_number":"W1232-B24","call_identifier":"FWF","name":"Molecular Drug Targets"}],"doi":"10.1016/j.jneumeth.2018.11.018","oa_version":"None"}
