生化机理
KIR2DL3(2DL3,原名 NKAT2,指定为 CD158b2)是一种 341 氨基酸(aa)的 I 型跨膜糖蛋白,属于人类杀伤细胞 Ig 样受体(KIR)分子家族。KIRs 在人类 CD56dim NK 细胞和 T 细胞亚群上表达,调节先天性免疫系统的效应功能。KIRs 因其胞外结构域(ECD)中 Ig 样结构域(二维或三维)的数量以及胞质尾部的长短(L、S)而得名。个体会表达不同多态性的抑制性和激活性 KIRs 子集。与其他抑制型 KIR 一样,KIR2DL3 的长尾上也有两个 ITIM 结构域,可阻止激活型受体聚集。在 ECD 中,KIR2DL3 与 KIR2DL2 有非常高的 aa 序列同一性(98%)。两者作为同一基因的等位基因分离;都能识别含 Asn80 的 HLA-C1,也能识别含 Lys80 的 C2 异型,但识别能力较弱。KIR2DL1 的细胞外 aa 相同度也很高(93%)。这三种分子共同识别并抑制 NK 对表达任何 HLA-C 异型的细胞的细胞毒性,从而实现自我识别。与 KIR2DL2 相比,KIR2DL3 对 HLA-C1 配体的亲和力较低;与 KIR2DL1 相比,KIR2DL3 对 HLA-C1 配体的亲和力较低,但特异性更强。抑制性和激活性 KIR 的配置可改变个体对病毒、自身免疫性疾病和白血病的易感性。例如,KIR2DL3 阳性而 KIR2DS3 阴性的类风湿性关节炎患者可更早确诊疾病。
