ABSTRACT
Objective:To investigate the promotive effect of dendritic cells(DCs) on proliferation of CRTH2 (CD4(+)CD294(+)Th2) cells and the influence of CRTH2 cells on secretion of immunoglobulin from B cells so as to provide a new approach for amplification and sorting of Th2 cells. Methods:DCs were induced from peripheral blood mononuclear cells, then the loaded-BCGV-Ag-DCs were cocultured with T cells, and the mixed lymphocyte reaction(MLR) was performed by CCK8 method. The phenotypes of DCs and CRTH2 cells were detected by flow cytometry. CRTH2 cells sorted by MACS were co-cultured with B cells for 5 days to detect the secretion of immunoglobulin. Results:The subsets and absolute number CRTH2 cells were significantly increased by loaded-BCGV-Ag-DCs. The levels of IgG, IgA and IgE were higher increased in supernatant of CRTH2 and B cell co-culture system than that in control group or that in transwell group(P<0.05). Conclusion:The proliferation of CRTH2 cells can be greatly promoted by loaded-BCGV-Ag-DCs, and the CRTH2 cells can help B cells to secrete IgG, IgA and IgE.
