应用同型特异性多克隆抗体对PC12神经内分泌细胞系VAMP-1和VAMP-2的表达和细胞内分布进行了研究。膜组分中检测到VAMP-2,而未检测到VAMP-1。亚细胞分离表明,相当数量的VAMP-2(24-36%)与致密的核心含儿茶酚胺颗粒(DCGS)有关。免疫荧光显微镜证实了这一点。破伤风神经毒素L链可抑制通透性PC12细胞颗粒介导的分泌,以及肉毒神经毒素F和G,可有效切割DCG相关的VAMP-2。这些数据表明VAMP-2存在于PC12细胞的分泌颗粒上。
The presence and intracellular distribution of vesicle-associated membrane protein-1 (VAMP-1) and VAMP-2 were investigated in the PC12 neuroendocrine cell line using isotype-specific polyclonal antibodies. VAMP-2 was detected in the total membrane fraction, while VAMP-1 was undetectable. Subcellular fractionation demonstrates that a substantial amount of the VAMP-2 (24-36%) is associated with dense core, catecholamine-containing granules (DCGs). This was confirmed by immunofluorescence microscopy. The L chain of tetanus neurotoxin, known to inhibit granule mediated secretion in permeabilized PC12 cells, as well as botulinum neurotoxins F and G, effectively cleaved DCG-associated VAMP-2. These data demonstrate that VAMP-2 is present on the secretory granules of PC12 cells.
