To study immunogenicity of a xenogeneic livin protein, we constructed an recombinant adenoviral vectors containing the human livin alpha genes (rAd-hlivin alpha) and vaccinated C57BL/6 mice with mouse bone marrow dendritic cells (BMDCs) transfected with rAd-hlivin alpha gave rise to potent livin-specific cytotoxic T lymphocyte (CTL) capable of lysing Lewis lung carcinoma (LLC) cells.
