摘      要：BACKGROUND:Human CD8 + CD28 - T-suppressor(Ts) cells have been considered to indicate a reduced need for immunosuppression in pediatric liver-intestine transplant recipients and recipients of deceased heart-kidney ***,in adult-to-adult living donor liver transplantation(A-A LDLT)little information is available and the clinical significance is still unknown. METHODS:Flow cytometry was used to detect the population of CD8+CD28 -Ts cells present in peripheral blood in A-A LDLT recipients(n=31),patients with end- stage liver disease(n=24)and healthy controls(n=19). Meanwhile,we tested the graft function and trough levels of immunosuppression in *** clinical and follow- up data of 31 transplant recipients were analyzed. RESULTS:Compared with diseased controls(P=0.007) and healthy individuals(P=0.000),a notable expansion of CD8 + CD28 - Ts cells was found in recipients of A-A *** was associated with graft function,levels of immunosuppression and rejection episodes. CONCLUSIONS:To monitor the CD8 + CD28 - Ts cells levels is important to evaluate the immune state of recipients. Meanwhile,it is also important to promote expansion of CD8+CD28 -Ts cells in recipients of A-A LDLT,not only to sustain good graft function and decrease the dosage of immunosuppressants,but also to reduce the occurrence of rejection.
