AIM:To explore dendritic cells (DCs) multiple functions in immune modulation.METHODS:We used bone-marrow derived dendritic cells from BALB/c mice pulsed with pseudo particles from the hepatitis C virus to vaccinate naive BALB/c mice.Hepatitis C virus (HCV) pseudo particles consist of the genotype 1b derived envelope proteins E1 and E2,covering a non-HCV core structure.Thus,not a single epitope,but the whole "viral surface" induces immunogenicity.For vaccination,mature and activated DC were injected subcutaneously twice.RESULTS:Humoral and cellular immune responses measured by enzyme-linked immunosorbent assay and interferon-gamma enzyme-linked immunosorbent spot test showed antibody production as well as T-cells directed against HCV.Furthermore,T-cell responses confirmed two highly immunogenic regions in E1 and E2 outside the hypervariable region 1.CONCLUSION:Our results indicate dendritic cells as a promising vaccination model for HCV infection that should be evaluated further.
