The regulated secretion of chemical signals in the brain occurs principally from two organelles, synaptic vesicles and dense core vesicles (DCVs). Synaptic vesicle secretion accounts for the well characterized local, fast signalling in synapses. DCVs contain a diverse collection of cargo, including many neuropeptides that trigger a multitude of modulatory effects with quite robust impact, for inst ...

...end with new human genetic data and complement with large-scale screens of mutant mice in order to identify and characterize disease-relevant mutations in synaptic proteins and corresponding mouse models. Proteomic tools will be used to analyse the protein components of synapses, and protein interaction networks of synaptic disease gene products will be mapped systematically. In parallel, smart li ...
