Abstract
The natural killer (NK) cell activity of human peripheral blood lymphocytes falls following major surgical procedures including renal transplantation but in non-immunosuppressed individuals returns to normal levels within the first 72 hr after operation. In renal allograft recipients, if this early postoperative fall is excluded from the analysis, NK cell function appears to follow changes in allograft function, suggesting that in vivo, as has been reported in vitro, NK activity is generated during activation of the alloreactive process. In an additional group of patients whose grafts were functioning for between 3 and 102 months after cadaveric renal transplantation using conventional immunosuppression, NK function was depressed in comparison with that of control subjects. However, some patients who were more than 48 months post-transplant had normal NK cell activity. Collectively, these results suggest that NK cell function may recover despite the continued administration of conventional immunosuppressive agents.This publication has 23 references indexed in Scilit:
