Abstract: Objective To investigate costimulatory molecules CD80 and CD86 expression in acute myelogenous leukemic cells and clinical implication.MethodsThe expression of CD80 and CD86 in the patients with acute myelogenous leukemia and HL-60 cells,U937 cells,NB4 cells,K567 cells was confirmed by Flow Cytometer.ResultsCD80 was very low or no expression in patients with acute myelogenous leukemia.CD86 expressed in acute myelogenous leukemia (27.86±19.65)%,which was much higher than that in control group[(1.21±0.13)%,t＝3.55,P＜0.01].No significant changes were observed in the expression of CD86 in M4 cells(48.65±21.92)%,M5 cells(39.25±18.67)% and control group(50.20±20.31)%(P＞0.05).After the cells were cultured for 24 h and 48 h,the expression of CD86 was (30.62±5.35)% and (29.43±4.67)% in HL-60 cells ,(24.12±5.23)% and (26.56±6.54)% in U937 cells,and,(21.25±3.78)% and (23.21±6.98)% in NB4 cells (all P＞0.05).The expression of CD80 and CD86 was very low in K562 cells.ConclusionsCostimulatory molecules CD86 expressed in acute myelogenous leukemic cells in the patients with acute myelogenous leukemia and HL-60 cells,U937 cells,NB4 cells.
