This cytokine plays a key role in allergic inflammation and immune responses to parasite infections. It synergizes with IL-2 to regulate interferon-gamma synthesis and stimulates B-cell proliferation as well as the activation of eosinophils, basophils, and mast cells. It also regulates IL-33 activity by modulating the production of transmembrane and soluble forms of IL1RL1. It antagonizes Th1-driven proinflammatory responses, downregulating cytokines like IL-1, IL-6, IL-10, IL-12, and TNF-alpha, partly through NF-kappa-B suppression. Additionally, it induces VCAM1 in endothelial cells, aiding eosinophil recruitment.
