Interleukin-5 (IL-5) is a highly specialized cytokine primarily responsible for regulating the production, activation, recruitment, and survival of eosinophils. Unlike multifunctional cytokines such as IL-2 or IL-4, IL-5 has a relatively focused scope of action, serving as the central orchestrator of eosinophil-related immune responses. It plays a pivotal role in both anti-parasitic defense and the pathogenesis of allergic diseases.
