Courses Taught : PSL450H1
Keywords: Exocytosis, SNARE, Munc18, syntaxin, CAPS1, V-ATPase.
Detailed Description: Dr. Sugita primary interest is to understand the molecular mechanisms of exocytosis from neuronal and immune cells with particular emphasis on the roles of Munc18, Munc13, CAPS1 and V-ATPase. Dr. Sugita uses PC12 cells and RBL-2H3 cells as cellular models for neuroendocrine cells and mast cells, respectively. Dr. Sugita also uses C. elegans as an in vivo model. Dr. Sugita is also generating conditional knockout mice for these proteins to analyze their functions in vitro and in vivo. Dr. Sugita also aims to elucidate the role of Munc18-1 in neuroprotection by revealing why Munc18-1 knockout in neurons causes severe neurodegeneration.
