The IL-4/IL-13 signaling pathways include IL13RA1, IL13RA2, and IL4R subunits, which are IL-13 receptors. They are connected to the pathophysiology and advancement of therapeutics for asthma, cancer and allergic diseases. IL13RA2 is being clinically tested as a possible cancer vaccination and CAR-T treatment target as a glioma-specific cell-surface epitope.
Functionally, there are two categories of IL-13 receptors: shared and private. IL13RA1 and IL4R make up the common IL-13 receptor. Additionally, IL-13 may bind to the exclusive IL-13 receptor IL13RA2. The main IL13-binding component of the IL-13 receptors is IL13RA1. By functioning as a decoy receptor with a greater affinity, IL13RA2 may inhibit IL-13-induced STAT6 activation.
By triggering AP-1 signaling and the synthesis of TGF beta, TNF-alpha and IL-13 signaling may cause the overexpression of IL-13RA2, which can have pro-fibrotic consequences. In order to facilitate IL-4 signaling, IL-4R can additionally complex with the common gamma chain (γc/IL2RG).
