| 摘 要： | 目的观察一种新型组织相容性白细胞抗原(histocompatibility leukocyte antigen, HLA)衍生肽(RDP1258)的免疫抑制功能并探讨其机制.方法人工固相合成一种HLA衍生肽(RDP1258),用 3 H-TdR法观察其在体外对大鼠脾细胞增殖反应的影响,以酶化学法观察其对脾细胞血红素氧合酶-1(heme oxygenase-1, HO-1)活性的影响.结果 RDP1258可显著抑制淋巴细胞转化及MLR的增殖反应;该肽体外降低HO活性呈现出剂量依赖性.结论 RDP1258能够显著抑制大鼠脾细胞经丝裂原或同种抗原刺激引起的增殖反应,这种作用可能是通过影响HO-1活性而达到的.

| 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. |
