  • Title: Enhanced prostacyclin synthesis in acute human kidney transplant rejection.
    Author: Leithner C, Sinzinger H, Silberbauer K, Wolf A, Stummvoll HK, Pinggera W.
    Journal: Proc Eur Dial Transplant Assoc; 1980; 17():424-8. PubMed ID: 7017684.
    Abstract:
    In acute and chronic kidney transplant rejection renal cortical and medullary tissue samples were examined for their prostacyclin (PGI2) generation by bioassay and compared with normal tissue. In acute rejection PGI2 formation was significantly enhanced, particularly in the cortex. In chronic rejection the PGI2 formation was comparable with control tissue. Since PGI2 is a very potent platelet aggregation inhibitor and vasodilator, it is concluded that the increase in PGI2 generation in acute rejection might be a self protecting mechanism which is, however, overwhelmed in irreversible rejection.
