Transforming growth factor-β1 and lung allograft fibrosis1

Abstract

The risks of lung allograft fibrosis increases with recurrent rejection, tissue eosinophilia, homozygous TGF-beta1 genotype and the use of bypass machine. Fibrosis was associated with higher mortality and morbidity might be explained by the TGF-beta1 immunosuppressive and fibrotic properties. Immunological strategies to down-regulate TGF-beta1 production might improve survival and function of lung allografts.
