Abstract

Immunotherapy has revolutionized cancer treatment, yet most patients do not respond. While tumor antigens are needed for effective immunotherapy, a favorable tumor immune microenvironment is also critical. In this review, we discuss emerging evidence that tumor cells exploit cellular plasticity and dedifferentiation programs to avoid immune surveillance, which in turn drives metastatic dissemination and resistance to immunotherapy. A deeper understanding of these programs may provide novel opportunities to enhance the efficacy of existing immunotherapies.

摘要

免疫疗法已经彻底改变了癌症治疗方法,但大多数患者没有响应。虽然肿瘤抗原是有效免疫疗法所必需的,但有利的肿瘤免疫微环境也是至关重要的。在这篇综述中,我们讨论了新出现的证据,即肿瘤细胞利用细胞可塑性和去分化程序来逃避免疫监视,这反过来又推动了转移扩散和对免疫疗法的耐药性。对这些程序的更深入了解可能为增强现有免疫疗法的疗效提供新的机会。
