CSPG4
CSPG4全称为硫酸软骨素蛋白聚糖4(Chondroitin Sulfate Proteoglycan 4),又名神经胶质抗原NG2或黑色素瘤相关硫酸软骨素蛋白聚糖(MCSP),是一种跨膜糖蛋白。其结构包含可结合硫酸软骨素链的胞外区域,广泛表达于血管周细胞及多种恶性肿瘤细胞表面,尤其在黑色素瘤、胶质瘤、乳腺癌中异常高表达。CSPG4通过调控细胞与微环境的相互作用,促进肿瘤细胞迁移、侵袭及血管生成,其活性与整合素、生长因子受体等分子存在交叉对话,影响MAPK、PI3K-AKT等促生存信号通路的激活。
CSPG4的过表达与肿瘤复发、耐药性及不良预后密切相关,成为实体瘤治疗的热门靶点。基于此开发的靶向药物包括单克隆抗体(如mAb 9.2.27)、抗体药物偶联物以及CAR-T细胞疗法,其中部分已进入黑色素瘤的临床试验阶段。CSPG4在创伤修复和纤维化疾病中的作用也受到关注,例如肺纤维化模型中CSPG4阳性周细胞的异常活化可能加剧组织损伤。尽管靶向CSPG4的疗法尚未上市,但其在肿瘤微环境中的枢纽地位为联合用药提供了新思路。
