Objectives:
The existed literatures indicated that galectin-1 has anti-inflammatory effects and plays a pivotal role in autoimmune diseases. Present study was to identify the roles of galectin-1 in acute animal renal allograft rejection.
Methods:
Rat acute rejection models were erected by allogeneic renal transplantation. Galectin-1 injection was performed in different concentrations in renal recipients post-transplantation. Recipient survivals, CD8+ T cell proliferation, production of IFN-gamma, levels of serum CD30, enzyme-linked immunoabsorbent spot assay (ELISPOT) and immunohistochemistry were observed or tested 7days after renal transplantation.
Results:
Galectin-1 injection can prolong the recipient animal survival, reduce the serum levels of IFN-gamma, soluble CD30, percentage of CD8+ T cell subset, CD8+ T cell-mediated cytotoxicity, and IFN-gamma ELISPOT frequency for allograft recipients. The therapeutic effects of galectin-1 injection on recipient rats were dose-dependent.
Conclusion:
Galectin-1 plays an important role in CD8+ T cell-mediated renal rejection by inducing immunological tolerance.
