Abstract:
Objective To investigate the immunosuppression function of a novel HLA derived peptide, RDP1258, and its mechanisms. Methods A peptide derived from HLA, RDP1258, was chemically synthesized by artificial solid phase synthesis. Effects of the peptide on alloreactive cytotoxic activity of rat spleen cells and heme oxygenase 1 (HO 1) activity were observed using 3H TdR method and enzyme chemistry method, respectively. Results The synthetic HLA derived peptide could obviously inhibit the proliferation of rat spleen cells and mixed lymphocyte reaction, and reduce HO activity in a dose dependent manner in vitro . Conclusion RDP1258 can significantly inhibit the proliferation of rat spleen cells induced by mitogen and isoantigen possibly by means of affecting HO 1 activity.
