摘要: 近年研究表明,周细胞(PCs)与肿瘤微环境(TME)内的各类细胞成分(如癌细胞、基质细胞、免疫细胞)存在紧密的相互作用关系,可通过异常的旁分泌通路介导肿瘤偏好性的肿瘤血管新生及失能,形成免疫抑制性TME并促进肿瘤进展。结合最新的非小细胞肺癌研究进展,本文就PCs在TME中的潜在功能与作用进行了综述,并讨论了靶向PCs的肿瘤抗血管治疗及肿瘤血管正常化治疗在重塑TME中的潜在价值,即通过靶向PCs肿瘤血管正常化而突破现阶段联合抗血管治疗实体瘤的困境,该理念或将成为改善化疗、小分子抑制剂靶向治疗及免疫检查点抑制剂治疗等联合抗肿瘤治疗的新策略。

Abstract:

Recent studies demonstrate that, the close interactions between pericytes (PCs) and various cells (such as cancer cells, stromal cells and immune cells) in tumor microenvironment (TME) can build an immunosuppressive TME to favor cancer growth and progression by modulating tumor angiogenesis and dysfunction via abnormal paracrine signaling pathways. In this review, we focused on recent advances in non-small-cell-lung-cancer to understand the regulatory role of PCs in TME and discussed the potential value of targeting PCs for inhibiting tumor angiogenesis and normalizing tumor vasculature to remodel TME, indicating that we can break through the dilemma of combined anti vascular therapy for solid tumors at this stage by targeting the normalization of tumor blood vessels of PCs. This may be a new strategy that could be used combinedly to improve chemotherapy, small molecule inhibitor targeted therapy or immune checkpoint inhibitor therapy.
