We have isolated a vesicular stomatitis virus (VSV)-specific CD4+ CD8- murine T-cell clone. This clone proliferates only in response to VSV and lyses infected tumor cells bearing class II major histocompatibility antigens in short-term chromium release assays. In addition, the cell has VSV antigens on its surface and is capable of killing uninfected tumor cells without major histocompatibility antigen restriction in a 2-day assay. This latter cytolytic activity is eliminated by anti-VSV antibody, indicating that its lytic activity is provided by the virus. [35S]methionine labeling and immunoprecipitation experiments demonstrated that viral protein translation is initiated after incubation of the clone with a tumor target cell, defining this as the mechanism of its cytolytic activity.

When mouse L cells are infected for 22 hr with vesicular stomatitis virus (VSV), a ribonucleic acid-containing enveloped virus, greater than 70% of the major histocompatibility antigen (H-2), is no longer detectable by the method of inhibition of immune cytolysis. Infected cells prelabeled with (14)C-glucosamine also show a correspondingly greater loss of trichloroacetic acid-insoluble radioactivity than uninfected cells. The loss of H-2 antigenic activity is not due to the viral inhibition of host cell protein synthesis since cells cultured for 18 hr in the presence of cycloheximide have the same amount of H-2 activity as untreated controls. Also, cells infected with encephalomyocarditis virus, a picornavirus, show no loss of H-2 activity at a time when host cell protein synthesis is completely inhibited. VSV structural proteins associated in vitro with uninfected L-cell plasma membranes do not render H-2 sites inaccessible to the assay. Although antibodies may not combine with all the H-2 antigenic sites on the plasma membrane, anti-H-2 serum reacted with L cells before infection does not prevent a normal infection with VSV. H-2 activity can be detected in virus samples purified from the medium of infected L cells; this virus purified after being mixed with L-cell homogenates shows greater H-2 activity than virus purified after being mixed with HeLa cell homogenates. However, VSV made in HeLa cells shows no H-2 activity when mixed with L-cell homogenates.

It is shown that liposomes containing (i) a fluorescein-labeled murine histocompatibility antigen (FITC-H-2Kk) and the G protein of vesicular stomatitis virus or (ii) H-2Kk and fluorescein-labeled viral protein (FITC-G) can elicit H-2-restricted syngeneic antiviral cytotoxic T cells as assayed by 51Cr release from appropriate virus-infected target cells. Fluorescence recovery after photobleaching was used to measure the diffusion coefficients of these reconstituted proteins in four different samples: (i) FITC-H-2Kk; (ii) FITC-H-2Kk and G; (iii) FITC-G; and (iv) FITC-G and H-2Kk. The same rate of lateral diffusion (D = 1 x 10(-8) cm2/sec at 37 degrees C in 25% cholesterol/75% dimyristoylphosphatidylcholine) was obtained in every case. Both proteins, fluorescent as well as nonfluorescent, could be patched by using specific antibodies. When G was patched with antibody, FITC-H-2Kk did not copatch. When H-2Kk was patched with antibody FITC-G did not copatch. These diffusion and patching measurements rule out the possibility that these proteins have either extensive oligomeric associations or strong specific pairwise associations.

A mouse major histocompatibility antigen (H-2) gene, encoding a novel H-2Ld molecule lacking its intracytoplasmic domain, has been constructed and introduced into mouse L-cells. The novel H-2 molecule is found on the surface of the transfected cells at the same level as L-cells transfected with the native H-2Ld gene. Allo- and influenza-specific cytotoxic T lymphocytes can recognize the truncated H-2 gene product nearly as efficiently as the normal H-2Ld gene product. However, vesicular stomatitis virus-specific cytotoxic T lymphocytes recognize the truncated H-2Ld molecule less efficiently than the complete H-2Ld product. The rate of capping of the truncated H-2Ld molecule was investigated and found to be the same as that of the complete H-2Ld gene product.
