产品介绍 B7-H4 protein is expressed on the surface of a variety of immune cells and functions as a negative regulator of T cell responses. While B7-H4 mRNA is widely distributed in mouse and human peripheral tissues, cell surface expression of B7-H4 protein is limited and shows an inducible pattern on hematopoietic cells. Putative receptor of B7-H4 can be upregulated on activated T cells. By arresting cell cycle, B7-H4 ligation of T cells has a profound inhibitory effect on the growth, cytokine secretion, and development of cytotoxicity. Administration of B7-H4Ig into mice impairs antigen-specific T cell responses whereas blockade of endogenous B7-H4 by specific monoclonal antibody promotes T cell responses. B7-H4 thus may participate in negative regulation of cell-mediated immunity in peripheral tissues.
B7-H4(B7 Homolog 4)是B7家族中的新成员,它能通过抑制T细胞的增殖、细胞因子的产生和细胞周期的进程来负性调控T细胞的免疫应答,其大量表达B7-H4还可以促进上皮细胞的恶性转化,保护表皮细胞免于失巢凋亡,在肿瘤的发生,进展和转归中发挥重要作用.
目前对B7-H4信号通路的进一步的研究必将为自身免疫性疾病、病毒感染性疾病和器官移植后排斥反应中T细胞介导的免疫应答调控提供了新的途径,同时也为肿瘤的诊断、治疗提供崭新的前景。
