摘要
Abstract
ObjectiveTo study the effects of dendritic cells (DC) transfected with recombinant vaccinia virus encoding Epstein-Barr virus (EBV) latent membrane protein 2A(LMP2A) gene,and to provide evidence for further investigation on the therapeutic vaccines against EBV-associated malignancies.MethodsMature DC were transfected with EBV-LMP2A recombinant vaccinia virus (rVV-LMP2A).Before and after the transfection,the expression of surface antigens on mature DC including CD1a,CD83,CD40,CD80,HLA-DR was measured by fluorescence activated cell sorter (FACS) and the function of DC to stimulate allogeneic T cells proliferation was measured by mixed leukocyte reactions (MLR).ResultsLMP2A protein was highly expressed (66.1%) in DC after the transfection of rVV-LMP2A.No significant changes in the primary surface antigens expression and in the MLR were detected during the transfection.Transfected DC still had strong potential in stimulating the proliferation of allogeneic T cells.ConclusionRecombinant vaccinia virus was an effective and non-perturbing vector to mediate the transfection of LMP2A into DC.The functions of mature DC were not affected significantly by the transfection of Vac-LMP2A.This study could provide evidence for the further immunotherapy of EBV-associated malignancies,e.g.nasopharyngeal carcinoma (NPC).``关键词
