靶向巨噬细胞的癌症治疗策略
Macrophage-directed therapeutic strategies in cancer.
肿瘤相关巨噬细胞(TAMs)是肿瘤微环境的主要组成部分,具有显著的功能可塑性,根据所处的微环境信号,既可表现为促进肿瘤进展的免疫抑制细胞,也可表现为支持抗肿瘤免疫的免疫刺激细胞。

近年来,由于部分患者实现了显著的肿瘤清除,癌症免疫治疗获得了关注。
近年来,癌症免疫治疗因部分患者出现显著肿瘤清除而受到关注。尽管免疫检查点阻断(ICB)在多种恶性肿瘤中取得重要成功,利用免疫系统靶向治疗前列腺癌(PCa)仍处于起步阶段。前列腺癌异质性高、肿瘤微环境呈“冷”状态且新抗原数量少等因素,均限制治疗应答。目前正在投入大量努力以改进基于免疫的前列腺癌疗法。本文综述前列腺癌免疫治疗现状,讨论多种免疫策略,包括疫苗、过继转移T细胞和双特异性T细胞衔接器,其中部分已进入临床试验。此外,本文还关注具有免疫调节作用的新型机制导向小分子酪氨酸激酶抑制剂;这些药物单用或与其他免疫疗法联合,均有望改善临床结局。
Cancer immunotherapy has gained traction in recent years owing to remarkable tumor clearance in some patients. Despite the notable success of immune checkpoint blockade (ICB) in multiple malignancies, engagement of the immune system for targeted prostate cancer (PCa) therapy is still in its infancy. Multiple factors contribute to limited response, including the heterogeneity of PCa, the cold tumor microenvironment, and a low number of neoantigens. Significant effort is being invested in improving immune-based PCa therapies. This review is a summary of the status of immunotherapy in treating PCa, with a discussion of multiple immune modalities, including vaccines, adoptively transferred T cells, and bispecific T cell engagers, some of which are undergoing clinical trials. In addition, this review also focuses on emerging mechanism-based small-molecule tyrosine kinase inhibitors with immune modulatory properties that, either as single agents or in combination with other immunotherapies, have the potential to improve clinical outcomes.
