( Northwestern University ) Northwestern researchers have discovered why immune cells of people with rheumatoid arthritis become hyperactive and attack the joints and bones. The cells have lost their bouncer, the burly protein that keeps them in line the way a bouncer in a nightclub controls rowdy patrons. The protein, called P21, prevents immune cells from their destructive rampage. When the ...

An engineered protein reduces arthritis symptoms in mice. A new protein engineered to inhibit molecules that cause inflammation not only reduces symptoms of rheumatoid arthritis in mice but also may have potential to reverse the disease's course. Researchers hope the findings will point toward a new therapy for this crippling and difficult-to-treat disease, which occurs when the immune system ...

Scientists have found a protein that acts as a master switch to determine whether certain white blood cells will boost or dampen inflammation, a finding that may help the search for new drugs for rheumatoid arthritis.
