T cell immunoglobulin domain and mucin domain-3 (TIM-3) is an important immune checkpoint (IC) protein in cancer immunosuppression that is considered a novel target for immunotherapy. Moreover, TIM-3, an immuno-myeloid regulator, is highly expressed on the cells of several solid tumors and myeloid leukemia stem cells (LSCs). TIM-3 blockade was shown to have dual effects for directly inhibiting leukemia cells and restoring T cell activation. We summarize several of the latest reports on the role of TIM-3 in immunotherapy for hematological malignancies from the 2022 ASH Annual Meeting (ASH2022).
T细胞免疫球蛋白结构域和粘蛋白结构域3(TIM-3)是癌症免疫抑制中一种重要的免疫检查点(IC)蛋白,被认为是免疫治疗的新靶点。此外,TIM-3作为一种免疫髓系调节因子,在几种实体瘤细胞和髓系白血病干细胞(LSCs)上高度表达。TIM-3阻断已显示出直接抑制白血病细胞和恢复T细胞活化的双重作用。我们总结了2022年美国血液学会年会(ASH2022)上关于TIM-3在血液系统恶性肿瘤免疫治疗中作用的几篇最新报道。
