Many virus infections give rise to surprisingly limited T-cell responses directed to very few immunodominant determinants. We have been examining the cytotoxic T-lymphocyte (CTL) response to herpes simplex virus type 1 (HSV-1) infection. Previous studies have identified the glycoprotein B-derived peptide from residues 498 to 505 (gB(498-505)) as one of at(More)
The spread of a "cream" mutant in a wild population of house mice is reported. The hypothesis that the gene responsible for the colour, extreme chinchilla, ce, has spread because of linkage with a major gene for warfarin-resistance, is tested by a linkage backcross. The results prove that a major gene does exist, that it is very closely linked with frizzy,(More)
The enormous diversity of the T cell pool makes it difficult to determine whether inherent biases in the naive TCR repertoire can influence T cell responsiveness. In C57BL/6 mice the cytotoxic T lymphocyte response to an immunodominant HSV-1 determinant (gB) is characterized by a prominent bias in Vbeta element usage, associated with a conserved and(More)
A second trapping of wild mice from two sites in a Peruvian river valley confirms the unprecedented high mutant incidence established by a previous trapping. It also shows that the population may be localized. The new mutants are different from those found in the first trapping, and thus indicate a continued source of mutagenic activity either external or(More)
