QS-21 Stimulon
产品介绍 | QS-21 是一种免疫刺激型皂甙,可作为有效的疫苗佐剂。QS-21 通过作用于抗原呈递细胞 (APC) 和 T 细胞,刺激 Th2 体液和 Th1 细胞介导的免疫反应。QS-21 可以激活 NLRP3 炎性小体,释放 caspase-1 依赖性细胞因子 IL-1β 和 IL-18。 | ||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
生物活性 | QS-21, an immunostimulatory saponin, could be used as a potent vaccine adjuvant. QS-21 stimulates Th2 humoral and Th1 cell-mediated immune responses through action on antigen presenting cells (APCs) and T cells. QS-21 can activate the NLRP3 inflammasome with subsequent release of caspase-1 dependent cytokines, IL-1β and IL-18. | ||||||||||||||||

体内研究 |
Studies in mouse APCs (DCs and macrophages) identifie QS-21 as an activator of the NLRP3 inflammasome, and cause subsequent release of caspase-1 dependent proinflammatory cytokines I1-1β/I1-18 that can promote Th 17 cell maturation or drive INF-γ-mediated Th1 responses, respectively. 西域 has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
