WitrynaT cells are involved in almost all autoimmune diseases, particularly in organ specific autoimmune disorders (probably due a lack of T regulatory cells or the participation of Th17 cells). Macrophages, which are activated by T cells are also involved in tissue damage (release of toxic enzymes and oxidative free-radicals; Type IV). WitrynaAutoimmune diseases can be classified as systemic or organ-specific depending on the extent of their clinicopathology (Table 19-2). The systemic category includes systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), scleroderma, primary Sjögren's syndrome, dermatomyositis, and systemic vasculitides.
