    摘要: Cell surface gangliosides are presumed to play a role in cell growth and differentiation. Using monoclonal antibodies directed against G.sub.D3, a disialoganglioside expressed predominantly by cells of neuroectodermal origin, we have found that G.sub.D3 is expressed by a subpopulation of cells of the immune system including: a) fetal thymocytes in subcortical regions and near vessels, 2) lymph node lymphocytes in interfollicular areas and near vessels, and 3) a small subset of T cells in the peripheral blood. Mouse monoclonal antibodies (two IgGs, one IgM and F(ab').sub.2 fragments) reacting with G.sub.D3 were found to stimulate proliferation of T cells derived from peripheral blood. Proliferation induced by binding to G.sub.D3 could be augmented by exogenous IL-2, PMA, PHA or Protein A.

    摘要: This invention provides a non-melanocytic eucaryotic cell constitutively expressing biologically active human tyrosinase. The present invention also provides methods of producing biologically active human tyrosinase. Additionally, the invention provides a non-melanocytic eucaryotic cell which constitutively expresses biologically active human tyrosinase which in turn catalyzes the production of melanin. The melanin so produced may then be recovered.

    摘要: Tolerance of the immune system for endogenous gp100 can be overcome and an immune response stimulated by administration of xenogeneic or xenoexpressed gp100 antigen. For example, mouse gp100, or antigenically-effective portions thereof, can be used to stimulate an immune response to the corresponding differentiation antigen in a human subject. Administration of xenogeneic antigens in accordance with the invention results in an effective immunity against gp100 expressed by the cancer in the treated individual, thus providing a therapeutic approach to the treatment of cancers expressing gp100, such as melanoma.
