ABSTRACT
Objective To investigate the effect and the mechanism of the GITR-antibody(glucocorticoid-induced tumor necrosis factor receptor-ligand antibody) on the mouse leukemia model induced by L615.Methods The mouse leukemia models induced by L615 cells were divided into 4 groups negative controls(peritoneal injection of normal saline,0.2 ml/d),GITR group(GITR,100,infused through caudal vein 2 d before leukemic lymphocytes inoculation,again at dose of 50 ?g/each mouse after inoculation),Cyclophosphamide group(200 mg?kg~(-1)?d~(-1),intraperitoneal injection from the 3~(rd) day after inoculation for 3 d),GITR+ Cyclophosphamide group(100 mg?kg~(-1)?d~(-1) Cyclophosphamide instead).The survival time,leukocyte counting in the peripheal blood,liver and spleen index were calculated and the pathological examination of liver,spleen were performed.Results GITR-ligand could prolong the survival time of mouse leukemia model,lead the necrosis and apoptosis of leukemic cells in bone marrow,decrease the liver and spleen index,decrease and relieve the leukocyte increase of peripheal blood and the irregular swelling of liver and spleen.Conclusion Through immunoregulation,GITR-antibody can inhibit the L615 leukemic cells effectively,therefore inhibit the progress of leukemia to some extent.
