Mechanism of action

ATG (anti-thymocyte globulin) works by binding to and eliminating T cells, which are central mediators of immune rejection and autoimmune disease. The polyclonal antibody preparation targets multiple epitopes on T-cell surfaces, leading to complement-dependent and antibody-dependent cellular cytotoxicity. This profound T-cell depletion creates an immunosuppressive state useful in transplantation and severe autoimmune conditions.
