嗜酸性粒细胞是一种多功能粒细胞,最著名的是为宿主提供针对寄生虫的防御。矛盾的是,嗜酸性粒细胞也与过敏性炎症、哮喘和嗜酸性粒细胞增多综合征的发病机制有关。新出现的证据也支持利用嗜酸性粒细胞的细胞毒性能力并改变其方向来杀死实体瘤的潜力。嗜酸性粒细胞生理学的核心是白细胞介素 5 (IL-5) 及其受体 (IL-5R),该受体由配体特异性 α 链 (IL-5Rα) 和共同 β 链 (βc) 组成。嗜酸性粒细胞的活化可导致其脱颗粒,从而导致组织破坏性促炎介质和细胞毒性蛋白的快速释放,这对宿主既有益又有害。本综述讨论了嗜酸性粒细胞免疫生物学和靶向 IL-5 和 IL-5R 的治疗策略,以及利用嗜酸性粒细胞细胞毒性作为肿瘤杀灭剂的潜力。
The eosinophil is a multifunctional granulocyte best known for providing host defense against parasites. Paradoxically, eosinophils are also implicated in the pathogenesis of allergic inflammation, asthma, and hypereosinophilic syndromes. Emerging evidence also supports the potential for harnessing the cytotoxic power of eosinophils and redirecting it to kill solid tumors. Central to eosinophil physiology is interleukin-5 (IL-5) and its receptor (IL-5R) which is composed of a ligand-specific alpha chain (IL-5Rα) and the common beta chain (βc). Eosinophil activation can lead to their degranulation, resulting in rapid release of an arsenal of tissue-destructive proinflammatory mediators and cytotoxic proteins that can be both beneficial and detrimental to the host. This review discusses eosinophil immunobiology and therapeutic strategies for targeting of IL-5 and IL-5R, as well as the potential for harnessing eosinophil cytotoxicity as a tumoricide.
