The pro-inflammatory cytokine IL-1 induced cellular response requires IL-1 receptor complex including IL-1RI and IL-1RAcP.
Recently, MyD88 was identified as an adaptor molecule in the IL-1 signaling pathway (1).
MyD88 associates with and recruits IRAK to the IL-1 receptor complex in response to IL-1 treatment and the dominant negative form of MyD88 attenuates IL-1R-mediated NF-kB activation.
MyD88 is also employed as a regulator molecule by IL-18 receptor and human Toll receptor (2,3), which are members of the Toll/IL-1R family of receptors.
Targeted disruption of the MyD88 gene results in loss of cellular responses to IL-1 and IL-18, and MyD88-deficient mice lack responses to bacterial product LPS that employs Toll-like receptors 2 and 4 (TLR2 and TLR4) as the signaling receptors.
MyD88 is a general adaptor protein for the Toll/IL-1R family of receptors and plays an important role in the inflammatory response induced by cytokines IL-1 and IL-18 and endotoxin.
The MyD88 gene is expressed in many tissues.
