Epigenetic mechanisms, including DNA methylation, histone post-translational modifications, and chromatin structure regulation, are critical for the interactions between tumor and immune cells. Emerging evidence shows that tumors commonly hijack various epigenetic mechanisms to escape immune restriction. As a result, the pharmaceutical modulation of epigenetic regulators, including 'writers', 'readers', 'erasers', and 'remodelers', is able to normalize the impaired immunosurveillance and/or trigger antitumor immune responses. Thus, epigenetic targeting agents are attractive immunomodulatory drugs and will have major impacts on immuno-oncology. Here, we discuss epigenetic regulators of the cancer-immunity cycle and current advances in developing epigenetic therapies to boost anticancer immune responses, either alone or in combination with current immunotherapies.
表观遗传机制,包括 DNA 甲基化、组蛋白翻译后修饰和染色质结构调控,对于肿瘤细胞和免疫细胞之间的相互作用至关重要。新出现的证据表明,肿瘤通常会利用各种表观遗传机制来逃避免疫限制。因此,对表观遗传调节剂(包括“写入器”、“读取器”、“擦除器”和“重塑器”)的药物调节能够使受损的免疫监视正常化和/或触发抗肿瘤免疫反应。因此,表观遗传靶向药物是有吸引力的免疫调节药物,将对肿瘤免疫治疗产生重大影响。在这里,我们讨论了癌症-免疫循环的表观遗传调节剂以及目前开发表观遗传疗法的进展,这些疗法可以单独或与现有的免疫疗法联合增强抗肿瘤免疫反应。
