ABSTRACT
The study was aimed to explore the stimulatory effect of tumor necrosis factorα (TNF-α) on differentiation and maturation of human peripheral blood mononuclear cell-derived dendritic cells (PBMNCDC). 30 ml of peripheral blood from healthy volunteers were collected, the PBMNC were isolated according to Thomas' method and were cultured with incubation of granulocyte/macrophage colony stimulating factor (GM-CSF), interleukin-4 (IL-4) for 8 day, and TNF-α was added on day 5. The expression of HLA-DR, CD83 and CD1a on surface of DC were detected by flow cytometry, the ability of DC to stimulate the proliferation of allogenic T cells was evaluated by MTT assay. The results showed that the TNF-α could up-regulate the expression of HLA-DR, CD83 and CD1a and activated DC could enhance the proliferation of allogenic T cells. Furthermore, the TNF-α at the concentration of 20 ng/ml was more effective. It is concluded that the TNF-α can effectively enhance the functional differentiation and maturation of the PBMNCDC and TNF-α at the concentration of 20 ng/ml is most effective to enhance differentiation and maturation of DC.
