Immunopharmacology Comments
Interleukin 13 receptor, α2 acts as a high affinity decoy receptor for interleukin 13 that sequesters the ligand away from IL13Rα1 and is involved in down-regulating IL-13 responses in vivo. IL13ra2 null mice exhibit enhanced IL-13 responses [4].
Increased expression of IL13Rα2 has been reported to promote tumor progression in glioma and other tumor models, and its expression is a prognostic marker for glioma malignancy grade and for poor patient survival [1,3]. This receptor has not been detected on normal brian tissue, making IL13Rα2 a novel selective drug target that has been intensively investigated for the treatment of glioblastoma, with several immunotherapeutic candidates advancing to clinical trial (reviewed in [2]).
