Research
Interests:
End stage kidney, liver, pancreas, and heart organ failure is a
major cause of morbidity and mortality. Organ transplantation is
often the only viable alternative to most patients with end stage
organ failure. Survival of clinical solid organ transplants has
increased remarkably in the FK506 cyclosporin era, however, the
long-term survival has not changed to the same degree. The primary
cause of graft failure is rejection. Therefore, an understanding
of the immunological mechanism involved may lead to prevention and
treatment of allograft rejection. This research is directed toward
understanding and manipulating immunoregulatory mechanisms essential
for acceptance of organ transplants. Historically, studies have
focused on organ specific antigens and cytokine roles in the induction
of the allograft reaction in human and dog models. Current studies
are directed toward the role of donor bone marrow cells on recipient
chimerism and graft adaptation.
