Interleukin-5

IL-5 (IL5, chr5q31.1) is a Th2 homodimer cytokine selectively driving eosinophil differentiation, survival, and recruitment via IL-5Rα/βc → JAK1/JAK2 → STAT5; mepolizumab and benralizumab (anti-IL-5/IL-5Rα) reduce eosinophilic asthma exacerbations 47-50%.

Also known as: IL-5, interleukin-5, IL5, eosinophil colony-stimulating factor, EDF, BCGF-II, B cell growth factor II
