Abstract:
Proton magnetic resonance spectroscopy of plasma indicates an alteration of proteolipid methyl and methylene resonances after heart transplantation. The intensity of these alterations is modulated by the transplant tolerance phenomena and allows the accurate detection of heart graft rejection. These results reinforce the analogy between the immunology of graft tolerance and the immunology of cancer or pregnancy where identical alterations have been identified.
