GMP IL-18 蛋白, Human (HEK293, His)

IL-18 protein is a pro-inflammatory cytokine that plays a critical role in epithelial barrier repair and polarized immune responses involving Th1 cells and NK cells. After binding to IL18R1 and IL18RAP, it forms a signaling ternary complex that activates NF-kappa-B, leading to the synthesis of inflammatory mediators. GMP IL-18 Protein, Human (HEK293, His) is the recombinant human-derived IL-18 protein, expressed by HEK293 , with C-6*His labeled tag.

IL-18 蛋白是一种促炎细胞因子，在上皮屏障修复和协调涉及 T 辅助细胞 1 (Th1) 细胞和自然杀伤 (NK) 细胞的极化免疫反应中发挥着关键作用。IL-18 与 IL18R1 和 IL18RAP 结合后，形成信号三元复合物，激活 NF-κ-B，导致炎症介质的合成。它与 IL-12 协同作用，诱导 Th1 细胞和 NK 细胞合成 IFNG。值得注意的是，IL-18 参与细胞焦亡下游的炎症转导，其成熟形式通过gasdermin-D (GSDMD) 孔释放到细胞外环境中。在质膜上，IL-18 与配体结合受体亚基 IL18R1 和信号受体亚基 IL18RAP 形成三元复合物，启动细胞内信号传导。此外，IL-18 与货物受体 TMED10 相互作用，促进其从细胞质易位至内质网-高尔基中间室 (ERGIC) 并随后分泌。
