IL18R1 is composed of an alpha and a beta subunit that combine to form a high affinity receptor for IL-18. IL18R1 alpha chain, also known as CDw218a, is a 75-80 kD type I transmembrane protein. It is expressed on NK cells, neutrophils, endothelial cells, and subsets of T and B cells. The expression of CDw218a on lymphocytes is upregulated after activation. The interaction of IL-18 and IL-18 receptor has been reported to be implicated in promotion of Th1 cytokine production and atherogenesis. The H44 antibody is specific for IL-18 receptor alpha chain and has been reported to block IL-18 binding to the receptor and to be useful for the identification of IL18R1 by flow cytometry and IHC.
