IL-18 Receptor

IL-18 Receptor is an interleukin receptor of the immunoglobulin superfamily. IL-18 Receptor consists of two distinct domains, IL-18Rα and IL-18Rβ. IL-18Rα alone has a weak affinity for IL-18 binding, while the IL-18Rα/β complex has a high affinity[1]. IL-18 binds to IL-18 receptor complex and activates NF-κB, MAPKs, PI3K/AKT signaling modules leading to the production and release of proinflammatory cytokines[2].
