SNARE-dependent mast cell (MC) exocytosis causes the release of a wide variety of mediators with important physiological/pathological consequences. Unlike synaptic transmission in the brain, which relies primarily on one set of exocytic SNAREs (i.e., Syntaxin1, SNAP-25, and VAMP2), MCs produce a multitude of exocytic SNAREs that can form a minimum of 8 distinct sets of fusogenic trans-SNARE complexes. Here we describe the genetic approaches we have developed to dissect the specific roles of these SNAREs in RBL-2H3 cells, a widely utilized model for studying MC signaling and exocytosis.

摘要

SNARE-dependent mast cell (MC) exocytosis causes the release of a wide variety of mediators with important physiological/pathological consequences. Unlike synaptic transmission in the brain, which relies primarily on one set of exocytic SNAREs (i.e., Syntaxin1, SNAP-25, and VAMP2), MCs produce a multitude of exocytic SNAREs that can form a minimum of 8 distinct sets of fusogenic trans-SNARE complexes. Here we describe the genetic approaches we have developed to dissect the specific roles of these SNAREs in RBL-2H3 cells, a widely utilized model for studying MC signaling and exocytosis.
