IL-5, on the other hand, activates eosinophils which promote an immune response by releasing more cytokines and leukotrienes.

另一方面，IL-5激活嗜酸性粒细胞，通过释放更多的细胞因子和白三烯来促进免疫反应。

Individuals with more severe forms of asthma might need additional treatments like daily corticosteroids, long-acting beta-adrenoceptor agonists, or leukotriene antagonists.

哮喘较为严重的患者可能需要额外的治疗，如日服皮质类固醇，施用长效的β肾上腺素受体激动剂或白三烯拮抗剂。

For example, IL-4 leads the production of IgE antibodies which coat mast cells and stimulate them to release granules containing things like histamines, leukotrienes and prostaglandins.

例如，IL-4导致了IgE抗体的产生，覆盖在肥大细胞表面，并刺激它们释放含有像组胺、白三烯和前列腺素等物质的颗粒。
