An Overview of Transplant Immunosuppression--History, Principles, and Current Practices in Kidney Transplantation.

From the historical first transplant in 1954 to the current transplant era, tremendous strides have been made in transplant immunology and immunosuppression. The most common immunosuppressive regimens use a combination of agents with differing modes of action to maximize efficacy and minimize the toxicities associated with each class of agent. The general categories of immunosuppressives are glucocorticoids, antimetabolites, calcineurin inhibitors, anti-lymphocyte antibody therapies (monoclonal and polyclonal), costimulation blockers, and mTOR inhibitors. This article reviews immunosuppressant medications, their actions, and significant side effects; discusses clinical management issues of immunosuppression; and describes future directions for the development of immunosuppressive medications.
