Pecam1
血小板内皮细胞黏附分子(PECAM1)又称为CD31,是相对分子质量为130kDa 的I 型跨膜糖蛋白,属于免疫球蛋白超家族成员。CD31 通常位于血管内皮细胞、血小板、巨噬细胞和kuffer细胞、粒细胞、T/NK细胞、淋巴细胞、巨核细胞、破骨细胞、嗜中性粒细胞。在某些肿瘤也发现CD31的表达,如上皮样血管内皮瘤、上皮样肉瘤样血管内皮瘤、其他血管肿瘤、组织细胞性恶性肿瘤和浆细胞。在循环血小板和白细胞中,CD31主要是通过调节其胞内结构域磷酸化顺序而限制细胞活化反应,通常是作为抑制性受体起作用。另外,D31也在内皮细胞细胞间连接处高度表达,作为机械传感器,白细胞运输的调节剂和维持内皮细胞连接完整性起作用。与CD31相关的大多数活性可归因于嗜同性CD31-CD31相互作用。其中包括白细胞外渗、骨髓造血和血管发育。CD31可以促进各种白细胞相关整联蛋白与ICAM/VCAM IgSF成员的结合,并帮助外周血白细胞穿过内皮屏障。促进CAM-IgSF结合是由于白细胞CD31-内皮细胞CD31参与后,β1和β2整联蛋白活性的普遍上调引起的。
在2015年ASCO会议上,Michael J. Birrer, MD团队结合他们的研究提出CD31是卵巢癌中贝伐单抗疗效的潜在标志物。因为贝伐单抗对无进展生存期和总生存期的影响在高CD31的患者中最为明显。这一发现再次引起了国内外学者对CD31的关注。
