Inhibition of bromodomain proteins in antigen presenting cells is shown herein to be more inflammatory, to display lower expression of the immunosuppressive molecule PDL1, and to be capable of restoring the responsiveness of tolerant T-cells. Therefore, disclosed is a method for promoting T-cell activation during cancer immunotherapy in a subject that involves administering to a subject undergoing cancer immunotherapy a composition comprising a bromodomain inhibitor. Also disclosed is a method for treating cancer in a subject, comprising co-administering to the subject a bromodomain inhibitor and an immunostimulatory agent.
本文表明,抑制抗原呈递细胞中的
溴化链蛋白会更具有炎症性,显示较低的免疫抑制分子 PDL1 表达,并能够恢复耐受性 T 细胞的反应性。因此,本发明公开了一种在癌症免疫治疗过程中促进受试者 T 细胞活化的方法,该方法包括向接受癌症免疫治疗的受试者施用包含
溴链
抑制剂的组合物。还公开了一种治疗受试者癌症的方法,该方法包括向受试者联合施用
溴链
抑制剂和免疫刺激剂。
