London: Scientists claimed to have developed a jab that uses your own immune cells to help ease the pain of arthritic knees. Researchers from the Newcastle University are currently testing the treatment in a clinical trial built on the theory that it will `reprogramme` the immune system in patients with rheumatoid arthritis, a newspaper reported.Rheumatoid arthritis is triggered by the immune system malfunctioning and mistakenly attacking healthy tissue in the body, specifically the cells that line the joints. This causes swelling, aching, throbbing pain and, eventually, deformity and damage to the joint. Hands, feet and wrists are most commonly affected, although other parts of the body can be damaged, too.
