Immunosuppression is a research area focused on studying and developing methods to suppress the immune system's activity. This is often done in medical contexts to prevent rejection of transplanted organs or to treat autoimmune diseases where the immune system attacks healthy tissue. Immunosuppression research may involve investigating drugs, therapies, or techniques that can effectively dampen immune responses without compromising the body's ability to fight off infections. Additionally, researchers in this field may explore the mechanisms underlying immune regulation and the development of novel immunosuppressive agents.
