    摘要: A mammalian homology of Drosophila Disabled protein has been identified and cloned. In particular, the murine homolog designated mDab1 has been cloned and expressed. mDab1, when tyrosine phosphorylated, binds to the SH2 domain of Src, Abl and Fyn. Antibodies specific for mDab1 are provided as are methods for the screening of agents for their ability to modulate mDab1 activity. Methods for diagnosing Disabled protein associated disease are also provided.

    摘要: The present invention relates to a method for inhibiting the adhesion of one cell to another comprising interfering with the interaction between the extracellular matrix receptor and its ligand.The invention is based upon the discovery that the α4β1 extracellular matrix receptor promotes adhesion of lymphocytes to endothelial cells via attachment to a defined peptide sequence. Prior to the present invention, the ligand of the α4β1 receptor had not been identified, nor had the function of the α4β1 receptor in lymphocyte attachment been known. By preventing the interaction between the α4β1 receptor and its ligands using antibodies or defined peptide sequences, the present invention enables, for the first time, specific intervention in the migration of lymphocytes through the vascular endothelium and into tissues. The present invention, therefore, has particular clinical utility in suppression of the immune response; in various specific embodiments of the invention, the adherence of lymphocytes to endothelium may be inhibited systemically, or may, alternatively, be localized to particular tissues or circumscribed areas. Accordingly, the present invention provides for treatment of diseases involving autoimmune responses as well as other chronic or relapsing activations of the immune system, including allergy, asthma, and chronic inflammatory skin conditions.

    摘要: The present invention demonstrates that JSRV envelope protein (Env) can be used to transduce human and other mammalian cells. Hybrid retrovirus packaging cells have been constructed that express the JSRV Env and retrovirus Gag-Pol proteins, and can produce JSRV-pseudotype vectors at high titers. Using high-titer virus the host range for JSRV has been established, and included sheep, human, monkey, bovine and dog cells, but not murine, rat or hamster cells. Retroviral packaging cell lines comprising the JSRV envelope protein, and receptor binding fragments thereof, are provided which transiently and stably produce high titers of recombinant retrovirus particles which can be used to transfer a heterologous gene to a eukaryotic cell.

    摘要: The present invention provides a rapid expansion method (termed "REM"), for quickly generating large numbers of T lymphocytes, including cytolytic and helper T lymphocytes. REM involves culturing the T cells in association with a disproportionately large concentration of nondividing feeder cells, preferably .gamma.-irradiated peripheral blood mononuclear cells ("PBMC") present at an excess of at least 40-fold (relative to the number of target T cells), more preferably at an excess of at least about 200-fold. Cultures grown under REM exhibit dramatically enhanced expansion rates that can be even further elevated by the use of appropriate concentrations of an additional feeder cell, an anti-CD3 monoclonal antibody and IL-2, as described herein. Clonal expansions in the range of 500-fold to 3000-fold can be achieved within a single stimulation cycle of about 10-13 days, which is more than 100-fold more efficient than currently employed methods of culturing human T cell clones. Genetic transduction efficiencies were also enhanced using REM-expanded T lymphocytes. Several examples involving human bone marrow transplant recipients illustrate the effective use of REM-expanded antigen-specific cytotoxic T lymphocytes for adoptive immunotherapy in humans.
