Rabbit polyclonal to IRAK4Interleukin-1 (IL-1) and lipopolysaccharide (LPS) induces cellular responses through IL-1 receptor (IL-1R) and Toll-like receptors (TLR). IL-1R-associated kinases (IRAK, IRAK2, and IRAKM) regulate the activation of NF-kB and MAP kinase (MAPK) by IL-1R/TLR. A novel member in the IRAK/Pelle family was recently identified and designated IRAK4. Overexpression of IRAK4 activates NF-kB and MAPK pathways. IRAK4 interacts with and phosphorylates IRAK1. IRAK4 deficient animals are completely resistant to the challenge with LPS. Animals and humans lacking IRAK4 are impaired in their responses to viral and bacterial challenges. Members in IRAK/Pelle family play a central role in IL-1R/TLR mediated inflammatory responses and in innate immunity. |
