This article focuses on the molecular characteristics and biological functions of interleukin-13 (IL-13), systematically elaborating its molecular mechanism as a core member of the Th2 cytokine family in activating the JAK-STAT6 signaling pathway through the type II receptor complex, analyzing the pathological driving roles of IL-13 in allergic airway diseases, fibrotic diseases, and tumor immunity, and exploring the application value of IL-13 detection in disease mechanism research, efficacy evaluation, and biomarker development.
