    We have initiated the molecular definition of the antigens recognized by Gross MuLV-specific cytolytic T lymphocytes on the surface of Gross MuLV-induced tumor cells. A panel of target cells was obtained by the double transfection and expression of a retrovirus gene and a foreign H-2 gene in recipient mouse fibroblasts. Our results show that class I H-2 transplantation antigens have a directive influence in determining the antigenicity of proteins encoded by the gag and env MuLV genes. Genes not linked to H-2 influence the intensity and the specificity of the cytolytic T lymphocyte response to Gross MuLV-induced tumors. Finally, MuLV-induced antigens expressed by transfected fibroblasts induce tumor immunity and lead to accelerated tumor rejection in vivo.

    Cytotoxic T Cells-mediated Immune Response

    Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
    Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
