abstract：:Interleukin-5 (IL-5) specifically induces the differentiation of eosinophils, which are important in host defence and the pathogenesis of allergies and asthma. Structurally, IL-5 is a unique member of the short-chain helical-bundle subfamily of cytokines whose canonical motif contains four helices (A-D) arranged in an...
