CD38
CD38是一种Ⅱ型跨膜糖蛋白,分子量为46kDa。1980年,CD38作为T细胞激活的特异性标记物,被E.L.Reinherz和S.F.Schlossman等科学家发现。CD38整体结构为N末端短的细胞质尾,单次跨膜域和C端较长的胞外区。CD38具有环化酶和水解酶的活性,是一种双功能胞外酶,参与核苷酸代谢。CD38使用NAD+作为底物来形成环状ADP核糖(cADPR)等核苷酸代谢产物。核苷酸代谢产物是有效的第二信使,可调节细胞质中Ca2+的动员,激活控制各种生物学过程的信号通路,例如淋巴细胞增殖、胰腺B细胞分泌胰岛素、T细胞活化等。CD38的这种活性对于维持体内NAD、烟酰胺等物质的动态平衡非常重要。也有研究发现,CD38同CD39、CD73、CD203a等一起,可降解ATP、NAD+、cADPR、AMP,从而产生ADO,诱导抑制性的免疫微环境。
CD38在人多种组织中都有表达,包括淋巴细胞、自然杀伤细胞、T细胞、B细胞单核细胞/巨噬细胞胰腺、脑、脾脏和肝细胞等。CD38的表达与多种疾病有关,包括艾滋病、自身免疫性疾病(例如系统性红斑狼疮)、Ⅱ型糖尿病、骨质疏松症和癌症。近年来,以CD38为靶点的多种新型免疫治疗方法已在临床前模型和临床试验中得到验证。2015年,强生公司联合开发的全人源抗CD38抗体达雷妥尤单抗(Daratumumab, Darzalex)获准用于治疗复发型、耐药型多发性骨髓瘤患者,是首个上市的CD38抗体药物。2020年3月2日,赛诺菲研发的抗肿瘤药物Isatuximab获得FDA批准,是继强生Darzalex之后第二款CD38抗体药物,同样是用于治疗复发性难治性多发性骨髓瘤。目前,无论Daratumumab还Isatuximab在多发性骨髓瘤治疗中均体现了显著的疗效。
