title: [Acceleration of mixed lymphocyte reaction by HCV C-Fc gene-transferred murine dendritic cells].
abstract: OBJECTIVE
  To observe the metergasis of murine dendritic cells (DCs) transfected with HCV C-Fc gene through electroporation.
  
  
  METHODS
  Mononucleocytes isolated from murine bone marrow were co-cultured with rmGM-CSF and rm-IL-4 for 7 days. Morphological characteristics of the cultured cells were observed under scan electron-microscope (SEM) and the expression of DEC205 on the cells was detected by FACS. DCs derived from the culture were transfected with plasmids containing HCV C-Fc gene. HCV C-Fc level in the transfected cells was detected by indirect immunofluorescence assay. MLR was studied with DCs and T cells.
  
  
  RESULTS
  Following 7-day culture, a large number of cells with typical characteristics of DC were observed. The HCV C-Fc level in the transfected DCs was higher. MLR was stimulated markedly by DCs transfected with HCV C-Fc gene in comparison with the control group.
  
  
  CONCLUSIONS
  A large number of DCs could be generated from murine bone marrow mononucleocyte cultures supplemented with GM-CSF and IL-4 for 1 week. The function of DCs transfected with pcDNA3HCV C-Fc was enhanced in MLR.
