Interleukin-18 receptor 1 (IL-18R1), CDw218a, is a cytokine receptor that belongs to the interleukin 1 receptor family. This receptor specifically binds interleukin 18 (IL18), and is essential for IL18 mediated signal transduction. IFN-alpha and IL12 are reported to induce the expression of this receptor in NK and T cells.

The functional IL-18 receptor complex is composed of two subunits designated IL-18 R alpha (IL-1 R5 and IL-1 Rrp) and IL-18 R beta ( IL-1 R7 and AcPL). Both IL-18 R alpha and IL-18 R beta belong to the IL-1 receptor superfamily. IL-18 R is widely expressed in numerous tissues including spleen, thymus, leukocyte, liver, lung, heart, small and large intestine, prostate and placenta.
