摘要:
The present invention provides compositions and methods for specifically inhibiting host immune responses against autoantigens. In particular, compositions and methods combining CD8 polypeptide expression with autoantigen expression or presentation are described for specifically inhibiting the humoral and cellular components of the host immune response to autoantigens.

The embodiments disclosed herein relate to the construction of fully-deleted Adenovirus-based gene delivery vectors packaged without helper Adenovirus, and more particularly to their use in gene therapy for gene and protein expression, vaccine development, and immunosuppressive therapy for allogeneic transplantation. In an embodiment, a method for propagating an adenoviral vector includes (a) providing an Adenovirus packaging cell line; (b) transfecting a fully-deleted Adenoviral vector construct into the cell line; and optionally (c) transfecting a packaging construct into the cell line, wherein the fully-deleted Adenoviral vector construct and optionally the packaging construct can transfect the Adenovirus packaging cell line resulting in the encapsidation of a fully-deleted Adenoviral vector independent of helper Adenovirus. In an embodiment, a target cell is transduced with the encapsidated fully-deleted Adenoviral vector for treating a condition, disease or a disorder.

The present invention relates to a product and process for suppressing an immune response using a T lymphocyte veto molecule capable of blocking cell surface molecules responsible for T cell activation. Disclosed is a CD4 or CD2 molecule, associated with an immunoglobulin molecule capable of binding to a major histocompatibility antigen. Also disclosed is a method to produce a T lymphocyte veto molecule, a therapeutic composition comprising a T lymphocyte veto molecule and methods to use T lymphocyte veto molecules in therapeutic processes requiring suppression of an immune response.

摘要:
A hybrid ligand molecular composed of an antibody combining site that binds to a T cell receptor complex structure and is capable of activating cytotoxic T lymphocytes linked to a target cell-specific antibody is disclosed. This ligand molecule can bind to an antigen on the surface of a target cell and to cytotoxic effector T lymphocyte cell receptor complex structures. A composition and a method for killing tumor cells with the hybrid ligand molecule of this invention are provided.
