PVR
脊髓灰質(zhì)炎病毒受體(poliovirus receptor,PVR)也稱CD155或Necl-5,是一種細(xì)胞黏附分子,屬于連接蛋白樣分子家族。CD155可在活化的NK細(xì)胞、CD4+和CD8+T細(xì)胞以及T-reg細(xì)胞上表達(dá)。在功能上,CD155與Nectin-3共同位于細(xì)胞連接處,兩者相互作用,共同調(diào)控細(xì)胞粘附和遷移。此外,CD155與T細(xì)胞或NK細(xì)胞表面共刺激分子CD226結(jié)合后,激活這些免疫細(xì)胞,可提高細(xì)胞因子分泌及對腫瘤細(xì)胞的殺傷能力。然而,當(dāng)腫瘤表面高表達(dá)的CD155一旦與NK和T細(xì)胞表面的TIGIT結(jié)合,它們對腫瘤細(xì)胞的殺傷作用就會被抑制。CD155在正常組織表達(dá)較少,但在多種惡性腫瘤組織中高表達(dá),包括結(jié)腸癌、肺癌、黑色素瘤、胰腺癌及膠質(zhì)母細(xì)胞瘤等等。大量研究表明,CD155可作為反映腫瘤進(jìn)展及預(yù)后的生物標(biāo)記分子。
