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.
依赖SNARE的肥大细胞（MC）胞吐作用会导致多种介质的释放，产生重要的生理/病理后果。与主要依赖一组胞吐SNARE（即Syntaxin1、SNAP - 25和VAMP2）的大脑突触传递不同，肥大细胞产生多种胞吐SNARE，它们可以形成至少8种不同的融合性反式SNARE复合物。在这里，我们描述了我们开发的遗传方法，以剖析这些SNARE在RBL - 2H3细胞中的特定作用，RBL - 2H3细胞是研究肥大细胞信号传导和胞吐作用广泛使用的模型。
