Title: Phenotype comparison between bone marrow derived dendritic cell and DC2.4 cell stimulated with antigen from Schistosoma japonicum
Abstract: Objective To compare the phenotypes of bone marrow derived dendritic cell(BMDC)and DC2.4 cell stimulated with GST from Schistosoma japonicum.Methods Bone marrow cells were cultured in the presence of IL-4 and GM-CSF to induce dendritic cells.DC2.4 cells were cultured as routine.Both cells were stimulated with GST and the expressions of CD40,CD80 and CD86 on the cells'surface were analyzed by FACS,using PBS and lipopolysaccharide as controls. Results After stimulating with GST,the means of fluorescence intensity(MFI)for CD40,CD80 and CD86 on BMDC surface were 100.39,42.38 and 170.83,respectively.Compared with PBS control,the MFI of CD80 and CD86 on BMDC,but not CD40,enhanced significantly.The MFIs of CD40.CD80 and CD86 on DC2.4 loaded by GST were 23.73,72.13 and 59.58 respectively.Compared with PBS control,the expressions of CD40 and CD86 enhanced significantly after schistosome antigen stimulation.Conclusion The expressions of cell surface molecules after schistosome antigen GST stimulation were different between BMDC and DC2.4.
