摘要:

T细胞免疫球蛋白和免疫受体酪氨酸抑制性基序结构域[T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif(ITIM)domain, TIGIT]是一种在免疫细胞表面表达的穿膜糖蛋白。TIGIT在膀胱癌中表达上调,会对膀胱癌的发生发展及不良预后产生重要影响,阻断TIGIT信号的免疫治疗有望改善膀胱癌患者的预后。随着研究的深入,TIGIT很有可能成为膀胱癌诊断和治疗的靶点。现对TIGIT的结构、免疫调节功能及其在膀胱癌治疗中的应用进行综述。

Abstract:

T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain TIGIT) is a transmembrane glycoprotein expressed on the surface of immune cells. TIGIT expression is up-regulated in bladder cancer and will have an important impact on bladder cancer development and poor prognosis. Immunotherapy that blocks TIGIT signaling is expected to improve the prognosis of bladder cancer. With further research, TIGIT is likely to become a target for bladder cancer diagnosis and treatment. This article reviews the structure, immunomodulatory effect and the research progress of TIGIT in bladder cancer.

Key words: TIGIT, bladder cancer, CD155, immuno-inhibitory receptor, immunotherapy
