PVR
脊髓灰质炎病毒受体(poliovirus receptor,PVR)也称CD155或Necl-5,是一种细胞黏附分子,属于连接蛋白样分子家族。CD155可在活化的NK细胞、CD4+和CD8+T细胞以及T-reg细胞上表达。在功能上,CD155与Nectin-3共同位于细胞连接处,两者相互作用,共同调控细胞粘附和迁移。此外,CD155与T细胞或NK细胞表面共刺激分子CD226结合后,激活这些免疫细胞,可提高细胞因子分泌及对肿瘤细胞的杀伤能力。然而,当肿瘤表面高表达的CD155一旦与NK和T细胞表面的TIGIT结合,它们对肿瘤细胞的杀伤作用就会被抑制。CD155在正常组织表达较少,但在多种恶性肿瘤组织中高表达,包括结肠癌、肺癌、黑色素瘤、胰腺癌及胶质母细胞瘤等等。大量研究表明,CD155可作为反映肿瘤进展及预后的生物标记分子。
