前言虽然长期以来嗜酸性白细胞一直被认为能帮助机体抵御各种病源性感染,但是其生理学作用一直未能确定。不过,最近的研究认方,这种细胞是机体发炎前的一种病理性细胞,具有一种极重要的组织杀伤能力。这主要是基于该细胞激活后,能 Although eosinophils have long been considered to help the body against various pathogenic infections, its physiological role has not been identified. However, recent research has identified the cell as a pathological cell prior to inflammation and has an extremely important tissue-killing ability. This is mainly based on the ability of the cell to activate
