MHC-I-restricted epitopes conserved among variola and other related orthopoxviruses are recognized by T cells 30 years after vaccination

MHC-I-restricted epitopes conserved among variola and other related orthopoxviruses are... It is many years since the general population has been vaccinated against smallpox virus. Here, we report that human leukocyte antigen (HLA) class I restricted T cell epitopes can be recognized more than 30 years after vaccination. Using bioinformatic methods, we predicted 177 potential cytotoxic T lymphocyte epitopes. Eight epitopes were confirmed to stimulate IFN-γ release by T cells in smallpox-vaccinated subjects. The epitopes were restricted by five supertypes (HLA-A1, -A2, -A24 -A26 and -B44). Significant T cell responses were detected against 8 of 45 peptides with an HLA class I affinity of K D less than or equal to 5 nM, whereas no T cell responses were detected against 60 peptides with an HLA affinity of K D more than 5 nM. All epitopes were fully conserved in seven variola, vaccinia and cowpox strains. Knowledge of the long-term response to smallpox vaccination may lead to a better understanding of poxvirus immunity and may aid in the development of new improved vaccines and diagnostic tools. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
