Abstract excerpt
Variant viruses mutated in the immunodominant cytotoxic T cell epitope surface (S) glycoprotein S-510-518 are selected in mice chronically infected with mouse hepatitis virus, strain JHM. We determined whether this selection occurred in the presence of an oligoclonal or polyclonal T cell response using soluble MHC/peptide tetramers in direct ex vivo analyses of CNS-derived lymphocytes. A total of 42% (range,...
