While we normally think of T cells as recognizing invaders, their roles are more complex. For example, some T cells, called regulatory T cells (Tregs) suppress conventional T cells’ immune responses. Because conventional T cells can escape normal controls and drive autoimmune diseases such as rheumatoid arthritis and type 1 diabetes, as well as rejection of transplants, Tregs are increasingly viewed as a way to rein in autoimmune diseases.
