"Clingy" blood platelets may help people with rheumatoid arthritis. Research shows that a sub population of lymphocytes involved in rheumatoid arthritis has platelets attached to their surface. The platelets reduced the lymphocytes' ability to cause disease by reducing activity levels and ability to spread. This research may lead to investigations into treatments that bind platelets to lymphocytes, and the ability to predicting the severity of the disease.
