The discovery of a 'molecular switch' could lead to new ways of treating infections such as MRSA, and inflammatory diseases like arthritis. According to research published today in Nature, the team from Imperial College London and the University of California, San Diego, have identified an enzyme called IKK, which can act as a 'brake' on an immune cell pathway responsible for regulating the body's response to infection and inflammation. By inhibiting IKK activity the researchers were able to increase the body's ability to fight off infection, but at the same time also increased the body's inflammatory response. They also found that IKKa inhibits activation of immune cells, and inhibits inflammation, a discovery which could lead to new ways of treating diseases such as arthritis. Dr Toby Lawrence, a Wellcome Trust International Research Fellow from Imperial College London, based at the Kennedy Institute of Rheumatology, and lead author of the research, says: "The identification of this 'double-edged sword' could be of huge importance in how we deal with a number of major health issues, including MRSA. With antibacterial resistance on the rise, this development could provide doctors with a new way to stop infections without resorting to a cocktail of antibiotics.
