title: Induction of hepatitis C virus-specific cytotoxic T lymphocytes in mice by immunization with dendritic cells transduced with replication-defective recombinant adenovirus.
abstract: We studied the potential of dendritic cells (DCs) in priming hepatitis C virus (HCV)-specific cytotoxic T lymphocytes (CTLs) in mice. Recombinant adenovirus expressing HCV core (Adex1SR3ST) was employed to express core in DCs. Core-specific CTLs are effectively elicited by injecting Adex1SR3ST-transduced DCs, whereas injection of Adex1SR3ST does not result in effective priming. Further, Adex1SR3ST-transduced DCs more efficiently prime core-specific CTLs than Adex1SR3ST-transduced macrophages, or DCs treated with an anthrax toxin fusion protein reported previously. Upon challenge with recombinant HCV-core-expressing vaccinia virus, vaccinia titers are significantly reduced in mice immunized with Adex1SR3ST-transduced DCs. Thus, adenovirus-transduced DCs may be a promising candidate for a CTL-based vaccine against HCV.
