Methods for the treatment of autoimmune disorders using immunosuppressive monoclonal antibodies with reduced toxicity

ActiveUS20070077246A1Treating and preventing and ameliorating symptomSlow and reduce damagePeptide/protein ingredientsAntipyreticAutoimmune conditionAutoimmune disease
The present invention provides methods of treating, preventing or ameliorating the symptoms of T cell-mediated immunological diseases, particularly autoimmune diseases, through the use of anti-CD3 antibodies. In particular, the methods of the invention provide for administration of antibodies that specifically bind the epsilon subunit within the human CD3 complex. Such antibodies modulate the T cell receptor / alloantigen interaction and, thus, regulate the T cell mediated cytotoxicity associated with autoimmune disorders. Additionally, the invention provides for modification of the anti-CD3 antibodies such that they exhibit reduced or eliminated effector function and T cell activation as compared to non-modified anti-CD3 antibodies.

Redirected, genetically-engineered t regulatory cells and their use in suppression of autoimmune and inflammatory disease

A redirected Treg cell is endowed with specificity toward a selected target antigen or ligand. The cell contains a chimeric receptor polypeptide that is expressed in a single, continuous chain, with an extracellular recognition region displayed on the surface of the cell, a transmembrane region and an intracellular signaling region. The extracellular recognition region is specific for the selected target antigen or ligand. The intracellular signaling region includes a combination of T-cell signaling polypeptide moieties, which combination, upon binding of the extracellular recognition region to the selected target antigen or ligand, triggers activation of the redirected Treg cells to cause suppression of T-cell mediated immunity. Such redirected Treg cells may be used to suppress undesired activity of T effector cells thereby mediating an immune or inflammatory response. They are particularly useful in treating T effector cell-mediated diseases, such as inflammatory bowel disease, transplant rejection and GVH disease.

Methods for using dendritic cells to activate gamma/delta-T cell receptor-positive T cells

This invention relates to methods of using human dendritic cells to present antigens for the induction of antigen-specific T cell-mediated immune responses. In particular, it relates to the isolation of dendritic cells from human blood, exposing the cells to antigens, co-culturing the antigen-pulsed dendritic cells with gammadelta-T cell receptor-positive-T cells (gammadelta-TCR<+> T cells) obtained from unprimed or weakly primed individuals for the stimulation of antigen-specific T cell proliferative and cytotoxic activities. The dendritic cell antigen presentation system described herein has a wide range of applications, including but not limited to, activation and expansion of large numbers of antigen-specific major histocompatibility complex-unrestricted T cells for use in adoptive cellular immunotherapy against infectious diseases and cancer.

VISTA regulatory T cell mediator protein, VISTA binding agents and use thereof

The present invention relates to a novel regulatory T cell protein. This protein, designated PD-L3 OR VISTA resembles members of the PD-L1 family, identified a novel and structurally-distinct, Ig-superfamily inhibitory ligand, whose extracellular domain bears homology to the B7 family ligand PD-L1. This molecule is designated as PD-L3 OR VISTA or V-domain Immunoglobulin Suppressor of T cell Activation (VISTA). Expression of VISTA is primarily within the hematopoietic compartment and is highly regulated on myeloid APCs and T cells. Therapeutic intervention of the VISTA inhibitory pathway represents a novel approach to modulate T cell-mediated immunity for the treatment of a wide variety of cancers, e.g., ovarian, bladder cancer and melanomas. Also, VISTA proteins, especially multimeric VISTA proteins and antibodies may be used to suppress T cell immunity in autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis and artritic conditions such as RA.

Regulation of T cell-mediated immunity by tryptophan

A mechanism of macrophage-induced T cell suppression is the selective elimination of tryptophan and / or increase in one or more tryptophan metabolites within the local macrophage microenvironment Studies demonstrate that expression of IDO can serve as a marker of suppression of T cell activation, and may play a significant role in allogeneic pregnancy and therefore other types of transplantation, and that inhibitors of IDO can be used to activate T cells and therefore enhance T cell activation when the T cells are suppressed by pregnancy, malignancy or a virus such as HIV. Inhibiting tryptophan degradation (and thereby increasing tryptophan concentration while decreasing tryptophan metabolite concentration), or supplementing tryptophan concentration, can therefore be used in addition to, or in place of, inhibitors of IDO. Similarly, increasing tryptophan degradation (thereby , decreasing tryptophan concentration and increasing tryptophan metabolite concentration), for example, by increasing IDO concentration or IDO activity, can suppress T cells. Although described particularly with reference to IDO regulation, one can instead manipulate local tryptophan concentrations, and / or modulate the activity of the high affinity tryptophan transporter, and / or administer other tryptophan degrading enzymes. Regulation can be further manipulated using cytokines such as macrophage colony stimulating factor, interferon gamma, alone or in combination with antigen or other cytokines.

Molecular vaccine linking intercellular spreading protein to an antigen

Superior molecular vaccines comprise nucleic acids, including naked DNA and replicon RNA, that encode a fusion polypeptide that includes an antigenic peptide or polypeptide against which an immune response is desired. Fused to the antigenic peptide is an intercellular spreading protein, in particular a herpes virus protein VP22 or a homologue or functional derivative thereof. Preferred spreading proteins are VP22 from HSV-1 and Marek's disease virus. The nucleic acid can encode any antigenic epitope of interest, preferably an epitope that is processed and presented by MHC class I proteins. Antigens of pathogenic organisms and cells such as tumor cells are preferred. Vaccines comprising HPV-16 E7 oncoprotein are exemplified. Also disclosed are methods of using the vaccines to induce heightened T cell mediated immunity, in particular by cytotoxic T lymphocytes, leading to protection from or treatment of a tumor.
