Transplantation Immunology

Research in this area concentrates on weakening both the acute and chronic phases of immune responses, to facilitate the acceptance of foreign organ and tissue transplants.  Program members focus on the basic biology of immune cell nonreactivity (tolerance) to foreign organs and tissues as well as on the use of new immunomodulatory agents to promote transplant acceptance without endangering patients’ abilities to resist infections.  Recent advances suggest that cellular reagents, such as tolerogenic dendritic cells, may have potential for inhibiting immune responses to antigens expressed and presented by these cells.
