    摘要: Based upon a strong correlation between regulator T cells (Treg cells) and suppressing or preventing a cytotoxic T cell response, provided are methods for the production of ex vivo activated and culture-expanded isolated CD4+CD25+ suppressor Treg cells for the prevention or suppression of immune reactions in a host, particularly in a human host, and including autoimmune responses. The resulting ex vivo culture-expanded Treg cells provide a sufficient amount of otherwise low numbers of such cells, having long term suppressor capability to permit therapeutic uses, including the preventing, suppressing, blocking or inhibiting the rejection of transplanted tissue in a human or other animal host, or protecting against graft vs host disease. Also provided are therapeutic and immunosuppressive methods utilizing the ex vivo culture-expanded Treg cells for human treatment, and high efficiency methods for research use.

    摘要: The invention provides purified ACT-4 receptor polypeptides, antibodies against these polypeptides and nucleic acids encoding ACT-4 receptor polypeptides. Also provided are methods of diagnosis and treatment using the same. ACT-4 receptors are preferentially expressed on the surface of activated CD4+ T-cells. ACT-4 receptors are usually expressed at low levels on the surface of activated CD8+ cells, and are usually substantially absent on resting T-cells, and on monocytes and B-cells (resting or activated). An exemplary ACT-4 receptor, termed ACT-4-h-1, has a signal sequence, an extracellular domain comprising three disulfide-bonded intrachain loops, a transmembrane domain, and an intracellular domain.
