Systemic Lupus Erythematosus (SLE) is a chronic autoimmune inflammatory disease (1) characterized by a breakdown of B and T cells tolerance to self-antigens (2). Defective clearance of apoptotic cells could promote the release of autoantigens which in turn trigger autoimmune responses(3‚ 4). Generated immune dysfunctions lead to the production of abundant of autoantibodies and inflammatory cytokines(5‚ 6). SLE can affect various organs of the body‚ on people of both sexes‚ all ages and all ethnic
