abstract

  • Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to identify intrarenal expression of cytotoxic attack molecules (granzyme B and perforin) and immunoregulatory cytokines (IL-2, IL-4, IL-10, IFN-gamma, and TGF-beta 1) in 127 human renal allograft biopsies. The biopsies were classified using the Banff criteria, and intrarenal gene expression was correlated with the histological diagnosis. Molecular analyses revealed that intragraft display of mRNA encoding granzyme B, IL-10 or IL-2 is a correlate of acute rejection, and intrarenal expression of TGF beta 1 mRNA, of chronic rejection. These data, in addition to demonstrating differential and highly selective intragraft gene expression during rejection, suggest that therapeutic strategies directed at the molecular correlates of rejection might refine existing anti-rejection strategies.
