IL-13R / CD213alpha1 Cell ELISA Kit

Background

Interleukin-13 receptor subunit alpha-1 (IL13RA1) is a protein that serves as a primary component of the interleukin-13 receptor (IL-13R) complex, a receptor essential for immune regulation and inflammatory responses. IL13RA1, encoded by the IL13RA1 gene, is a type I cytokine receptor that primarily binds to the cytokine interleukin-13 (IL-13), a cytokine associated with type 2 helper T cell (Th2) immune responses. IL13RA1 also participates in binding interleukin-4 (IL-4), a cytokine closely related to IL-13 in function and structure, by forming a complex with IL-4 receptor alpha (IL4RA). IL13RA1’s function in the immune system is particularly significant in responses to allergens, where it helps mediate the characteristic responses associated with allergic asthma, atopic dermatitis, and allergic rhinitis. Beyond allergy and inflammation, IL13RA1’s signaling pathways are implicated in fibrotic diseases and certain cancers, as IL-13 and IL-4 promote tissue remodeling, fibrosis, and immune modulation.
