生化机理
CCL2 又称单核细胞趋化蛋白1(MCP1)或 JE,是 CC 或 beta 趋化因子家族的成员,最著名的作用是作为单核细胞的趋化因子。人类 CCL2 cDNA 编码一个 99 氨基酸(aa)的前体蛋白,其中有一个 23 aa 的信号肽和一个 76 aa 的成熟蛋白。成熟蛋白的前 5 aa(包括 N 端吡咯烷酮羧酸修饰谷氨酰胺)通过金属蛋白酶裂解自然去除,并下调活性,但不影响受体结合。由于非共价二聚化和可变的碳水化合物含量,CCL2 在 SDSPAGE 上可形成 8.713.5 kDa 的多条带。成熟的人类 CCL2 与犬、猪和马的 CCL2 有 7879% 的相同 aa,而小鼠和大鼠表达的 CCL2 延长了 49 aa,在共同区域内只有 ~56% 的相同 aa。不过,人的 CCL2 可诱导鼠类细胞产生反应。成纤维细胞、胶质瘤细胞、平滑肌细胞、血管内皮细胞、淋巴细胞和单核吞噬细胞都能产生 CCL2,或在有丝分裂刺激下产生,但单核细胞和巨噬细胞似乎是主要来源。除了具有趋化活性外,CCL2 还能诱导单核细胞、NK 细胞和淋巴细胞释放酶和细胞因子,并诱导表达其受体 CCR2 的嗜碱性粒细胞释放组胺。此外,它还能促进 CD4+ T 细胞的 Th2 极化。CCL2介导的单核细胞向炎症部位的募集被认为在动脉粥样硬化、多发性硬化和过敏性哮喘的病理过程中发挥作用。增强单核细胞的抗肿瘤活性。与以单核细胞浸润为特征的疾病(如牛皮癣、类风湿性关节炎或动脉粥样硬化)的发病机制有关。可能参与了动脉粥样硬化疾病过程中单核细胞被招募到动脉壁的过程。
