title: Protection against lethal Sendai virus infection by in vivo priming of virus-specific cytotoxic T lymphocytes with a free synthetic peptide.
abstract: The only peptide of Sendai virus that is recognized by cytotoxic T lymphocytes (CTL) in B6 mice was found with (i) the use of recombinant vaccinia virus constructs containing separate genes of Sendai virus and (ii) a set of overlapping peptides completely spanning the identified nucleoprotein (NP) gene product. This immunodominant NP peptide is recognized by Sendai virus-specific CTL that are known to have therapeutic effects in vivo. By subcutaneous immunization, this peptide induced Sendai virus and NP peptide-specific CTL memory responses in vivo. Most importantly, mice that had been immunized with this peptide were protected against a lethal virus dose, indicating that viral peptides can be used as antiviral T-cell vaccines. The induction of T-cell memory by free peptide immunization potentially has wide applicability in biology and medicine, including protection against infectious disease.
