DOI: 10.1016/j.bbrc.2019.05.043
Abstract: The release of neurotransmitters via the fusion between synaptic vesicles and the presynaptic membrane is an essential step in synaptic transmission. Synaptic vesicles generally undergo two distinct modes of exocytosis called full-collapse fusion and kiss-and-run… read more here.

DOI: 10.1016/j.bpj.2016.11.2138
Abstract: Single vesicle-vesicle fusion assays based on FRET of lipid or content mixing [1-3] are widely used to investigate complexin on vesicle docking [4] and fast fusion process [5]. Most recently, we discovered the important role… read more here.

DOI: 10.1016/j.ceca.2018.06.004
Abstract: Continuous neurotransmitter release is subjected to synaptic vesicle availability, which in turn depends on vesicle recycling and the traffic of vesicles between pools. We studied the role of Synaptotagmin-7 (Syt-7) in synaptic vesicle accessibility for… read more here.

Transient docking of synaptic vesicles: Implications and mechanisms

DOI: 10.1016/j.conb.2022.102535
Abstract: As synaptic vesicles fuse, they must continually be replaced with new docked, fusion-competent vesicles to sustain neurotransmission. It has long been appreciated that vesicles are recruited to docking sites in an activity-dependent manner. However, once… read more here.

DOI: 10.1016/j.neuron.2022.01.007
Abstract: Many mammalian neurons release multiple neurotransmitters to activate diverse classes of postsynaptic ionotropic receptors. Entopeduncular nucleus somatostatin (EP Sst+) projection neurons to the lateral habenula (LHb) release both glutamate and GABA, but it is unclear… read more here.

DOI: 10.1021/acsomega.1c07206
Abstract: The transmission of neuronal information is propagated through synapses by neurotransmitters released from presynapses to postsynapses. Neurotransmitters released from the presynaptic vesicles activate receptors on the postsynaptic membrane. Glutamate acts as a major excitatory neurotransmitter… read more here.

DOI: 10.1073/pnas.2011870117
Abstract: Significance Mammalian central synapses of diverse functions contribute to highly complex brain organization, but the molecular basis of synaptic diversity remains open. This is because current synapse proteomics are restricted to the “average” composition of… read more here.
