Abstract:
ObjectiveTo induce monocyte-derived dendritic cells(MoDC)from acute myeloid leukemia (AML) and healthy persons by rhCD40L in normal human AB serum system in vitro and to identify the morphology and phenotype of MoDC. MethodsPeripheral blood mononuclear cells(PBMNC)of AML and healthy persons were cultured in RPMI 1640 media including human AB serum, GM-CSF, rhIL-4 and rhCD40L, respectively. MoDC were identified by morphological features, surface antigen expression and the ability to stimulate T cells. ResultsAfter cultured for 7 days, MoDC displayed typical morphology with elongated dendritic process,and upregulation of the costimulatory molecules CD40,CD80,CD86 and CD83.The morphology and expression of costimulatory molecules were not significantly different between AML and healthy persons (P＞0.05),but were significantly different between rhCD40L group and without rhCD40L group (P＜0.05). MoDC had the ability to activate T cells, and there were no statistical differences between AML and healthy persons(P ＞0.05), but were significant differences between rhCD40L group and without rhCD40L group (P＜0.05). MoDC started to secrete IL-12 on day 5, and there was no statistical differences between AML and healthy persons(P＞0.05),and had differences between rhCD40L group and without rhCD40L group (P＜0.05).ConclusionMoDC can be cultured from the peripheral blood of AML and healthy persons.There were no significant differences in morphology and phenotype.Monocyted-derived DC can be used as an alternative to generate leukemia-specific cytotoxic T cells,especially in the presence of rhCD40L.
