BACKGROUND.: Chronic allograft injury (CAI), characterized by interstitial fibrosis and tubular atrophy, leads to a progressive decline in graft function, resulting in the loss of 5% of renal transplants per annum, and eludes specific therapies. Galectin-3 (gal-3) is a β-galactoside-binding lectin expressed in diverse fibrotic tissue, and mice deficient in gal-3 have reduced fibrosis in kidney, liver, and lung models. The role of gal-3 in CAI is examined in this study. METHODS.: We adopted a murine model of CAI, characterized by a single class II mismatch between BM12 donor and C57BL/6 recipient strains. Syngeneic transplants served as controls (C57BL/6). Transplants were then performed between BM12 donors and gal-3 null recipients on a C57BL/6 background. RESULTS.: Transplantation of BM12 kidneys into C57BL6 mice was associated with interstitial fibrosis (P
