Mouse splenocytes were stained with anti-mouse CD4 APC/Cyanine7, anti-mouse FOXP3 Brilliant Violet 421™ and purified anti-mouse IL-33Rα (IL1RL1, ST2) (clone W17243F) (left) or purified rat IgG2a, κ isotype control (right) followed by PE anti-rat IgG. Data shown was gated on CD4-positive cells. -
ST2-FLAG transfected DO-11.10 mouse cells were stained with purified anti-mouse IL-33Rα (IL1RL1, ST2) (clone W17243F) (filled histogram), or purified rat IgG2a, κ isotype control (open histogram) followed by PE anti-rat IgG.
IL-33Rα, also known as ST2 or IL-1RL1, is a member of the Toll/IL-1 receptor family. It binds IL-33 and is structurally similar to IL-1R1. Two forms of the protein exist: a soluble form known as ST2 and a membrane anchored form known as ST2L. The membrane form is expressed by Th2 cells and bone marrow derived mast cells, whereas the soluble form is expressed by serum-stimulated fibroblasts. Signaling through IL1RL1 drives cytokine production in mast cells, basophils, eosinophils, invariant NKT and NK cells, Th2 lymphocytes, and type 2 innate immune cells. IL-33 signaling is required for maintaining the suppressive function of regulatory T cells.
