UCSD medical researchers show that a protein called I-kappa-B kinase alpha (IKKa) is responsible for terminating an inflammatory response before it can damage cells and organs. IKKa's mechanism involves interacting with proteins RelA and C-Rel, which bind to genes mediating the inflammatory response for a short duration.
Researchers from Imperial College London identified an enzyme called IKKá, which acts as a 'brake' on immune cell pathways. By inhibiting IKKa activity, the body's ability to fight off infection increased, but also led to higher inflammatory responses.
