近年来,变态反应研究中较大进展之一是对嗜酸性粒细胞在变态反应中的作用的研究。多年来虽已知嗜酸性粒细胞在变态反应病人的血液及病变组织中增多及浸润,但对其所起的作用却不清楚。直至最近才认识到:嗜酸性粒细胞可通过多种途径调节变态反应,对控制变态反应的发展起重要作用。 In recent years, one of the major advances in allergic research has been the study of the role of eosinophils in allergic reactions. Although it has been known for many years that eosinophils proliferate and infiltrate in the blood and diseased tissues of allergic patients, their role is unknown. It has only recently been recognized that eosinophils can regulate allergies in a variety of ways and play an important role in controlling the development of allergies.
