Objective: To explore the effect of calcium ionophore(CI)A23187 on dendritic cells(DCs) from healthy human peripheral blood monocytes(PBMNCs).Methods: PBMNCs from healthy donors were treated with A23187 and rhGM-CSF plus IL-4.After culturation of 72 hours,changes of cellular morphology were observed under light and electron microscopy.Surface makers on DCs were analyzed by flow cytometry.MTT colorimetry was used to detect proliferation of allogenetic T cells.Plasma concentrations of IL-12 and IFN-γ were mea...
