PE/Dazzle 594 anti-mouse IL-33Ralpha IL1RL1, ST2 Antibody - DIH9,BioLegend,145314

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.Blocking with anti-ST2 antibodies has been shown to alleviate experimental arthritis and airway inflammation.  The IL-33-ST2 axis has been reported to be important across a range of diseases including asthma, allergies, and cardiac disease.
