Anti Jo1 antibodies

Anti-Jo1 antibodies are autoantibodies that target an enzyme involved in protein synthesis. They are most commonly associated with polymyositis and dermatomyositis, inflammatory muscle diseases that cause muscle weakness and pain. These antibodies are also linked to a specific syndrome called anti-synthetase syndrome, which can affect the muscles, lungs, joints, and skin. Testing for Anti-Jo1 antibodies helps doctors identify inflammatory muscle conditions.
