**2. Induction agents**

The goal of induction therapy is to suppress both cellular and humoral responses to prevent episodes of acute rejection. Rabbit anti-thymocyte globulin (rATG), IL-2 receptor blockers, and Alemtuzumab (Campath), are the primary antilymphocyte antibody preparations that are currently used for induction. More than 80% of the transplant centers in the United States use induction agents immediately post transplantation.[3] The specific agent utilized is often based on multiple factors which include recipient risk for rejection, recipient race, presence of chronic infections such as Hepatitis B or C, HIV, and center preference. See Table 1. for common induction agents.
