This invention discloses a method of using fructose-1.6diphosphate (FDP) to help suppress the rejection of internal organs such as kidneys, hearts, etc. At least three major advantages of FDP in conjunction with organ transplants have ^^ identified: (1) FDP can help reduce the unwanted proliferation of certain types of stimulated lymphocytes which would otherwise pose a risk of attacking the non-self cells in the transplanted organ; (2) FDP can also potentiate me effectiveness of cyclosporine as a transplant-protecting immunosuppressant, thereby allowing a reduction in CSA dosages, which in turn can reduce the likelihood and the severity of toxic side effects and other dangers of CSA treatment; (3) FDP can also reduce the amount of damage n an organ during the removal and storage steps
