Abstract
T-cell infiltration was reduced, whereas the numbers of apoptotic cells increased, in rats treated with M2c. To explore the mechanisms of the protective role of M2c, the numbers of major histocompatibility complex (MHC) class II positive cells were found to be decreased and the expression of N-acetylglucosaminyltransferase V (MGAT5) was up-regulated in M2c infusion groups. Together, these findings demonstrate that polarization of macrophages towards the M2c phenotype ameliorated acute rejection in a rat LT model and may provide a novel and effective therapeutic approach for AR after transplantation.
