摘要:

三阴性乳腺癌是一种预后较差的乳腺癌亚型,缺乏有效的治疗手段。细胞周期蛋白依赖性激酶(CDK)4/6抑制剂能够通过影响三阴性乳腺癌免疫微环境促进抗肿瘤免疫,如提高肿瘤细胞表面程序性死亡蛋白配体-1蛋白表达、增强T细胞活化和抗原呈递、改变T细胞亚群比例、诱导淋巴细胞浸润等。免疫微环境的变化与肿瘤进展关系密切,但其机制极其复杂。探讨CDK4/6抑制剂影响免疫微环境的作用机制及相关的生物标志物,可为三阴性乳腺癌的诊治提供新的方向。

Abstract:

Triple negative breast cancer is a subtype of breast cancer with poor prognosis and lack of effective treatment. Cyclin dependent kinase(CDK)4/6 inhibitors promote antitumor immunity by influencing the triple negative breast cancer immune microenvironment, such as increasing the tumor cell surface pragrammed death-ligand 1 protein expression, enhancing T cell activation and antigen presentation, changing the proportion of T cell subgroup and inducing lymphocyte infiltration. The change of immune microenvironment is related to tumor progression, but its mechanism is extremely complex. Exploring the mechanism of CDK4/6 inhibitor affecting immune microenvironment and its biomarkers can provide a new direction for the diagnosis and treatment of triple negative breast cancer.
