BACKGROUND The virus-specific cytotoxic T lymphocyte (CTL) induction is an important target for the development of a broadly protective human influenza vaccine, since most CTL epitopes are found on internal viral proteins and relatively conserved. In this study, the possibility of developing a strain/subtype-independent human influenza vaccine was explored(More)
BACKGROUND To induce potent epitope-specific T cell immunity by a peptide-based vaccine, epitope peptides must be delivered efficiently to antigen-presenting cells (APCs) in vivo. Therefore, selecting an appropriate peptide carrier is crucial for the development of an effective peptide vaccine. In this study, we explored new peptide carriers which show(More)
This study was conducted to examine whether oral-health promotion programs provided as an occupational health service for employees were cost-beneficial for employers. The subjects were composed of 357 male workers (20-59 yr of age) who participated in oral-health promotion programs conducted at their workplaces between 1992 and 1997. The design of this(More)
