Anti-thymocyte Globulin (ATG)

Anti-thymocyte Globulin (ATG) is a medication derived from rabbit or horse antibodies that are used to target and reduce the number of T-cells, a type of white blood cell involved in the immune response. It is primarily used in medical treatments like organ transplantation and certain autoimmune disorders to help prevent the body from rejecting a transplanted organ or to suppress an overactive immune system. By diminishing T-cell activity, ATG can help create a more favorable environment for healing and acceptance of the transplanted tissue.
