title: Inability of mice to generate cytotoxic T lymphocytes to vesicular stomatitis virus restricted to H-2Kk or H-2Dk.
abstract: H-2k mice are unable to generate cytotoxic T lymphocytes (CTL) to vesicular stomatitis virus (VSV). This apparent unresponsiveness is found for both major serotypes of VSV, VSV-Indiana and VSV-New Jersey. CTL unresponsiveness occurs despite the ability of H-2k mice to generate a humoral immune response against VSV that is comparable to that found in responder (H-2b and H-2a) strains. All H-2k mice regardless of background genes, including various Ig allotypes, were found to be nonresponders. H-2k-linked unresponsiveness mapped to both H-2Kk and H-2Dk and occurred despite the presence of responder alleles in (responder x nonresponder)F1 mice. The unresponsiveness cannot be attributed to an inability of VSV-infected H-2k target cells to express viral surface antigens of H-2 molecules. Further, unresponsiveness cannot be overcome by using secondary stimulation in vivo or in vitro. H-2k-linked unresponsiveness does not appear to be due to suppression, and no complementation has been found in various (nonresponder x nonresponder)F1 mice. Thus unresponsiveness to VSV in association with H-2Kk or H-2Dk appears to represent an extensive defect of immune responsiveness that probably occurs because VSV is not a natural mouse pathogen.
