CD137/4-1BB Protein, Rhesus Macaque (HEK293, Fc)

MCE 国际站：CD137/4-1BB Protein, Rhesus Macaque (HEK293, Fc)

4-1BB (CD137; TNFRSF9)，是一种表面糖蛋白，是 TNFSF9/4-1BBL 的受体，属于肿瘤坏死因子 (TNF) 受体超家族。4-1BB 有助于T细胞的激活和发育，还诱导外周单核细胞增殖、向肿瘤微环境迁移。4-1BB 也参与增强 Nrf2 和 NF-κB 通路介导的内皮细胞凋亡。 重组恒河猴 CD137/4-1BB 蛋白 (HEK293, Fc) 全长 186 个氨基酸 (M1-Q186)，由 HEK294 细胞表达，带有 C 端 hFc 标签。

Synonyms: CD137; ILA; TNFRSF9; 4-1BB ligand receptor; CDw137

Species: Rhesus Macaque

研究背景：4-1BB, is encoded by TNFRSF9 (CD137, ILA), belongs to tumor necrosis factor (TNF) receptor superfamily. 4-1BB is a surface glycoprotein, expressed in a variety of cells, for example, T cells, B cells, natural killer (NK) cells, dendritic (DCs), eosinophils, and mast cells; even a variety of tumor cells such as human leukemia cells. It is widely spread in vascular smooth muscles, tumor vessel walls, and liver tissue of hepatocellular carcinoma. 4-1BB has a preference on CD8+ cells rather than CD4+ cells. It provides co-stimulatory signals and activates cytotoxic effects of CD8+ T cells and helps to form memory T cells. Finally, it promotes the immune system fighting against tumors. Moreover, CD137 binds CD137L to signal monocytes, increase their survival, proliferation and stimulate their migration and extravasation. In addition, it induces the release of various proinflammatory factors, leads to the influx of inflammatory monocytes into tissues and form an inflammatory environment. Specifically, CD137 promotes the migration of monocytes/macrophages to tumor microenvironment by upregulating the expression of Fra1. It also promoted the differentiation of monocytes/macrophages into osteoclasts at the same time, thus providing a favorable microenvironment for the colonization and growth of breast cancer cells in bone. It provides a promising therapeutic strategy for metastasis of breast cancer. Furthermore, CD137 signaling promotes endothelial cells (ECs) apoptosis through prooxidative and proinflammatory mechanisms, mediated by Nrf2 and NF-κB pathways, respectively. The homology of 4-1BB protein in human and mouse was low, and the sequence similarity was 56.75%.
