1.The conception of superantigen(SAgs) was created by White in 1989.They are a group of protein moleculars encoded by bacterials or virus, SAgs bind as unprocessed proteins to relatively invariant regions of MHC class II antigens, which are found mainly on professional antigen presenting cells(APCs).
超抗原(supperantigen SAg)的概念由White 等于1989 年首先提出,它是由一组细菌或病毒编码的蛋白分子可不需要抗原提呈细胞(APC)处理,以完整的蛋白质分子形式直接与APC 膜上的MHCⅡ类分子抗原结合槽外侧结合,导致带有特异性Vβ节段T 细胞大量活化增殖,其活化的T 细胞数是普通抗原数千倍乃至数万倍。收藏指正
