The Natural Killer Group 2D (NKG2D) receptor plays an important role in protecting the host from infections and cancer. By recognizing ligands induced on infected or tumor cells, NKG2D modulates lymphocyte activation and promotes immunity to eliminate ligand-expressing cells. Because these ligands are not widely expressed on healthy adult tissue, NKG2D ligands may present a useful target for immunotherapeutic approaches in cancer. Novel therapies targeting NKG2D ligands for the treatment of cancer have shown preclinical success and are poised to enter into clinical trials. In this review, the NKG2D receptor and its ligands are discussed in the context of cancer, infection, and autoimmunity. In addition, therapies targeting NKG2D ligands in cancer are also reviewed.
自然杀伤细胞2D(NKG2D)受体在保护宿主免受感染和癌症侵害方面发挥着重要作用。通过识别感染或肿瘤细胞上诱导产生的配体,NKG2D调节淋巴细胞活化并促进免疫反应以清除表达配体的细胞。由于这些配体在健康成人组织中并非广泛表达,NKG2D配体可能成为癌症免疫治疗方法的有用靶点。针对NKG2D配体治疗癌症的新型疗法已在临床前研究中取得成功,并有望进入临床试验。在本综述中,将在癌症、感染和自身免疫的背景下讨论NKG2D受体及其配体。此外,还将综述针对癌症中NKG2D配体的疗法。
