Antithymocyte globulin

Antithymocyte globulin (ATG) is a medication made from antibodies that target and destroy T cells, which are a type of immune cell involved in immune responses. It is used primarily to prevent or treat rejection in organ transplantation and to treat certain blood cancers. When administered, ATG reduces the activity of T cells, helping to prevent the body's immune system from attacking a transplanted organ or teaming up in disease processes. It is typically given through intravenous infusion in a hospital setting and may cause side effects like allergic reactions or increased risk of infection.
