This invention provides a method of inhibiting an autoimmune response in an animal suffering from an autoimmune disease selected from the group consisting of psoriasis, Lyme disease and hyper IgE syndrome which comprises administering to the animal, in an amount effective to treat the autoimmune disease, an antibody that binds specifically to a protein specifically recognized by monoclonal antibody 5c8 produced by the hybridoma having ATCC Accession No. HB 10916.
摘要:
This invention provides for an isolated protein specifically recognized by monoclonal antibody 5c8 produced by the hybridoma having ATCC Accession No. HB 10916. This invention also provides for an isolated protein having substantially the same biological activity as the aforementioned isolated protein. In addition, this invention provides for a pharmaceutical composition comprising the isolated protein and a pharmaceutically acceptable carrier.
摘要:
Activation of cells bearing CD40 on their cell surface by CD40 ligand is inhibited by contacting the cells with an agent capable of inhibiting interaction between CD40 ligand and the cells, in an amount effective to inhibit activation of the cells. Activation of cells bearing CD40 on their surface by CD40 ligand in a subject is inhibited by administering to the subject an agent capable of inhibiting interaction between CD40 ligand and the cells, in an amount effective to inhibit activation of the cells. Reperfusion injury, in an non-transplant recipient, is a condition associated with CD40 ligand-induced activation of CD40-bearing cells. Therefore, reperfusion injury can be treated by the administration of anti-human CD40L monoclonal antibodies, such as those described herein (e.g. 5c8 mAb).

The present invention provides for an isolated nucleic acid molecule encoding a light chain protein of an antibody, wherein the antibody binds specifically to a protein specifically recognized by monoclonal antibody 5c8 produced by the hybridoma having ATCC Accession Number HB 10916. The invention also provides for an isolated nucleic acid molecule encoding a heavy chain protein of an antibody, wherein the antibody binds specifically to a protein specifically recognized by monoclonal antibody 5c8 produced by the hybridoma having ATCC Accession Number HB 10916. The present invention also provides for a gene transfer vector comprising a nucleic acid molecule, a host vector system comprising the gene transfer vector, and a composition comprising a nucleic acid molecule.

Activation of cells bearing CD40 on their cell surface by CD40 ligand is inhibited by contacting the cells with an agent capable of inhibiting interaction between CD40 ligand and the cells, in an amount effective to inhibit activation of the cells. Activation of cells bearing CD40 on their surface by CD40 ligand in a subject is inhibited by administering to the subject an agent capable of inhibiting interaction between CD40 ligand and the cells, in an amount effective to inhibit activation of the cells. Conditions dependent on CD4O ligand-induced activation of CD40-bearing cells are treated.

This invention provides a monoclonal antibody which specifically recognizes and forms a complex with a protein located on the surface of activated T cells and thereby inhibits T cell activation of B cells. This invention also provides the monoclonal antibody 5c8 (ATCC Accession No. ______). This invention provides a human CD4− T cell leukemia cell line designated D1.1 (ATCC Accession No. ______) capable of constitutively providing contact-dependent helper function to B cells. This invention also provides an isolated protein from the surface of activated T cells, wherein the protein is necessary for T cell activation of B cells. This invention further provides an isolated, soluble protein from the surface of activated T cells, wherein the protein is necessary for T cell activation of B cells.
摘要:
A single-stranded nucleic acid molecule which encodes an amino acid sequence comprising at least a portion of a T4 glycoprotein is provided. Additionally, amino acid sequences which comprise at least a portion of a T4 glycoprotein and are useful as a prophylaxis for treating a subject with acquired immune deficiency syndrome are provided. These amino acid sequences, are capable of specifically forming a complex with a human immunodeficiency virus envelope glycoprotein and which are soluble in an aqueous solution. Monoclonal antibodies directed to the water-soluble amino acid sequences of the present invention may be used as vaccines for immunizing a subject against acquired immune deficiency syndrome.

摘要:
Methods are provided for inhibiting or enhancing down-regulation of an antigen-activated HLA-E+ T cell by an HLA-E-restricted CD8+ T cell comprising contacting the HLA-E* T cell and CD8+ T cell with an agent which inhibits or enhances, respectively, binding between (i) T cell receptor (TCR) on the surface of the CD8+ T cell and (ii) a self peptide presented by HLA-E on the surface of the HLA-E+ T cell, thereby inhibiting or enhancing, respectively, down-regulation of the antigen-activated HLA-E+ T cell. Compositions comprising agents which inhibit or enhance/activate, respectively, binding between (i) T cell receptor (TCR) on the surface of a CD8+ T cell and (ii) a self peptide presented by HLA-E on the surface of a HLA-E+ T cell, and assays for identifying such agents, are provided.
