Previously, we showed that transcutaneous (TC) DNA immunization by applying plasmid DNA onto a mouse skin area wherein the hair follicles were induced into growth stage by plucking the hair using warm waxing induced strong and functional antigen-specific antibody responses. In the present study, using plasmids that encode -galactosidase gene or ovalbumin (OVA) gene, we showed that this mode of TC DNA immunization not only induced specific antibody responses, but also induced antigen-specific cytotoxic T lymphocyte responses. In fact, TC DNA immunization using a plasmid that encodes OVA gene prevented the growth of OVA-expressing B16-OVA tumor cells in the immunized mice. Moreover, we provided additional evidence supporting that hair follicles are essential for this mode of TC DNA immunization.
