Background
Human IL-4R (Interleukin-4 Receptor) is a critical cell surface receptor involved in immune regulation and inflammatory responses, composed of the IL-4Rα chain (CD124) paired with either the common γ-chain (γc, CD132) or IL-13Rα1 to form Type I or Type II receptors. It binds cytokines IL-4 and IL-13, activating JAK-STAT signaling pathways that modulate immune cell functions, particularly in hematopoietic cells such as B cells, T cells, macrophages, and mast cells. IL-4R signaling promotes Th2 cell differentiation, IgE antibody class switching, and anti-inflammatory responses, playing a central role in allergic and immune-mediated diseases. Dysregulation of IL-4R is associated with conditions like asthma, atopic dermatitis, and autoimmune disorders. Due to its therapeutic potential, IL-4R has been successfully targeted by drugs such as dupilumab, offering effective treatment for allergic diseases. Ongoing research continues to explore IL-4R's broader roles in immunity and inflammation, paving the way for novel therapies targeting immune dysregulation.
