细胞周期失调是癌症的标志之一。细胞周期蛋白依赖性激酶4(CDK4)和CDK6在调控细胞周期及其他细胞功能中发挥关键作用。CDK4/6抑制剂在治疗乳腺癌方面取得了巨大成功,目前也正在其他肿瘤类型中广泛开展试验。越来越多的证据表明,CDK4/6抑制剂除诱导细胞周期阻滞外,还通过免疫调节发挥抗肿瘤作用。本文概述了CDK4/6抑制剂的免疫调节活性,讨论了耐药的免疫机制,并探索了将其与免疫检查点抑制剂(ICIs)或嵌合抗原受体(CAR)T细胞疗法联合以改善临床结局、发挥其免疫治疗潜力的途径。
The dysregulation of the cell cycle is one of the hallmarks of cancer. Cyclin-dependent kinase 4 (CDK4) and CDK6 play crucial roles in regulating cell cycle and other cellular functions. CDK4/6 inhibitors have achieved great success in treating breast cancers and are currently being tested extensively in other tumor types as well. Accumulating evidence suggests that CDK4/6 inhibitors exert antitumor effects through immunomodulation aside from cell cycle arrest.
Here we outline the immunomodulatory activities of CDK4/6 inhibitors, discuss the immune mechanisms of drug resistance and explore avenues to harness their immunotherapeutic potential when combined with immune checkpoint inhibitors (ICIs) or chimeric antigen receptor (CAR) T-cell therapy to improve the clinical outcomes.
