| Research Abstract |
In general, the most advantage of a peptide vaccine is its prominent safety. Peptide can be automatically and freely synthesized in accordance with the design for a desired antigenic epitope. Thus, unnecessary and inconvenient epitopes can be easily avoided from the vaccine.
In the course of developing a synthetic peptide vaccine for dental caries, we identified a unique13-mer peptide, TYEAALKQYEADL, as a minimum antigenic unit peptide inducing cross-inhibiting antibodies to a cell surface protein antigen of Streptococcus mutans. However, the immunogenicity of a small peptide is usually very weak and strictly controlled by MHC class II restriction. To develop a peptide vaccine, it is very important to improve the immunogenicity of peptides and to escape from the MHC restriction. In this research project, we have succeded in developing the original design(OMP-KK-U) covering the disadvantages of peptide antigens for a human being on the basis of the data from animal experiments using B10 congenic mice.
