Mechanism of action

ATG binds to and eliminates T cells, which are key drivers of immune-mediated rejection and autoimmune disease. By reducing circulating T lymphocytes, it prevents graft rejection in transplant recipients and suppresses pathogenic immune responses in autoimmune conditions. The mechanism involves both direct cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC).
