IL-18 receptor system consists of a ligand-binding subunit, IL-1Rrp and a signal transducing subunit, AcPL, analogous to the IL-1 receptor system.
The activated IL-1R???AcP complex recruits the serine/threonine kinase IL-1-receptor-associated kinase (IRAK) via the adaptor protein, MyD88.
After IRAK is phosphorylated, it dissociates from the receptor complex and interacts with TNF-receptor-associated factor 6 (TRAF6), which then relays the signal via NF-??B-inducing kinase (NIK) to two I-??B kinases (IKK-1 and IKK-2) leading to NF-??B activation.

MyD88 mediates a close interaction of the two related IRAK molecules,
which is essential to allow IRAK-4 to phosphorylate IRAK-1. Phosphorylation of IRAK-1
reduces its affinity for MyD88, while increasing its affinity for TRAF6
