產品介紹 |
background: 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. Function: Negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. Involved in promoting epithelial cell transformation. Subcellular Location: cell membrane; Single-pass type I membrane protein (Potential). Note=Expressed at the cell surface. A soluble form has also been detected. Tissue Specificity: Overexpressed in breast, ovarian, endometrial, renal cell (RCC) and non-small-cell lung cancers (NSCLC). Expressed on activated T- and B-cells, monocytes and dendritic cells, but not expressed in most normal tissues (at protein level). Widely expressed, including in kidney, liver, lung, ovary, placenta, spleen and testis. Post-translational modifications: N-glycosylated. Similarity: Belongs to the immunoglobulin superfamily. BTN/MOG family. Contains 2 Ig-like V-type (immunoglobulin-like) domains.

B7-H4(B7 Homolog 4)是B7家族中的新成員,它能通過抑制T細胞的增殖、細胞因子的產生和細胞周期的進程來負性調控T細胞的免疫應答,其大量表達B7-H4還可以促進上皮細胞的惡性轉化,保護表皮細胞免于失巢凋亡,在腫瘤的發生,進展和轉歸中發揮重要作用. 目前對B7-H4信號通路的進一步的研究必將為自身免疫性疾病、病毒感染性疾病和器官移植后排斥反應中T細胞介導的免疫應答調控提供了新的途徑,同時也為腫瘤的診斷、治療提供嶄新的前景。 |
