GMP IL-6 蛋白, Human

IL-6 protein is a multifunctional cytokine that plays multiple biological functions in immunity, tissue regeneration, and metabolism. After binding to IL6R, the resulting complex binds to the signaling subunit IL6ST/gp130, triggering the intracellular IL6 signaling pathway. GMP IL-6 Protein, Human is the recombinant human-derived IL-6 protein, expressed by E. coli , with tag free. GMP IL-6 Protein, Human, has molecular weight of ~20.0 kDa.

GMP IL-6 蛋白是一种多功能细胞因子，在免疫、组织再生和代谢中发挥多种生物学功能。与 IL6R 结合后，产生的复合物与信号亚基 IL6ST/gp130 结合，触发细胞内 IL6 信号通路。它与膜结合的 IL6R 和 IL6ST 的相互作用刺激“经典信号传导”，而 IL6 和可溶性 IL6R 与 IL6ST 的结合则诱导“反式信号传导”。此外，当发射细胞上的膜结合 IL6:IL6R 复合物激活邻近接收细胞上的 IL6ST 受体时，就会发生“簇信号传导”。IL-6 作为急性期反应的有效诱导剂，在感染和组织损伤期间快速动员宿主防御，尽管过度的 IL6 合成与疾病病理有关。在先天免疫反应中，IL-6 由骨髓细胞（例如巨噬细胞和树突状细胞）在感染或组织损伤部位通过 Toll 样受体识别病原体后合成。在适应性免疫反应中，IL-6对于B细胞分化为免疫球蛋白分泌细胞至关重要，并且在CD4(+) T细胞亚群的分化中发挥重要作用。它是生发中心形成所必需的滤泡辅助 T (Tfh) 细胞发育的关键因素，并且是驱动幼稚 CD4(+) T 细胞向 Th17 谱系所必需的。此外，IL-6 对于骨髓瘤细胞的增殖和浆母细胞的存活至关重要。
