摘要:
The present invention provides of using multimeric MHC class II/peptide complexes. In one aspect, methods provided for identifying MHC class II-restricted immune epitopes of a predetermined polypeptide antigen. Methods for identifying an immunostimulatory epitope for a predetermined polypeptide antigen are provided. In a related aspect, methods for screening a therapeutic polypeptide agent for an MHC class II epitope are provided. In other aspects, methods for modulating T cells and for determining or monitoring an MHC class II-restricted immune status of a patient are also provided.
摘要:
Provided are methods and compositions for labeling an allergen-specific pathogenic CD4+ T-cell. The method can comprise contacting a cell population comprising CD4+ T cells with a suspected allergen to provide a challenged cell population, contacting the challenged cell population, or a subpopulation thereof, with a first molecule that specifically binds to a biomarker for an allergen-specific pathogenic T cell, wherein binding of the first molecule to the biomarker on a CD4+ cell indicates the cell is an allergen-specific pathogenic CD4+ T cell, and detecting binding of the first molecule to a CD4+ cell, wherein binding to the cell indicates the cell is an allergen-specific pathogenic CD4+ T cell. The method is applicable to monitoring the presence of allergen-specific pathogenic CD4+ T cells and/or efficacy of immunotherapy for allergies in a subject.
摘要:

摘要:
Compositions for treating autoimmune, allergic, or atopic disease comprising a compound that inhibits hyaluronan synthesis and a pharmaceutically acceptable carrier are described. In some embodiments, the compound that inhibits hyaluronan synthesis is 4-methylumbelliferone or a metabolite of 4-methylumbelliferone. Methods for treating autoimmune diabetes, multiple sclerosis and/or autoimmune demyelination, including administering to the subject a composition having a compound in an amount effective to inhibit hyaluronan synthesis in a mammalian subject, are also described.
摘要:
A method for identifying an autoimmune or demyelinating disease in a subject is described. The method includes (a) FIRST COHORT obtaining a sample comprising CD4′ T cells from a subject; (b) determining a level of IL-6 responsiveness of CD4+ T cells from the sample; (c) comparing the level of IL-6 responsiveness determined in step (b) with a level of IL-6 responsiveness of CD4+ T cells in a sample from a healthy subject; and (d) identifying the subject as having an autoimmune or demyelinating disease based upon an elevated level of IL-6 responsiveness in the subject. Biomarkers include, for example, IL-6Rα and/or pSTAT3. Methods for identifying and characterizing multiple sclerosis and relapsing-remitting multiple sclerosis are also described.
摘要:
The present invention provides methods for generating mammalian T cell populations comprising antigen-specific CD4+CD25+ regulatory T cells from freshly isolated CD4+CD25− T cells. The method comprises selecting CD4+CD25− T cells from a sample obtained from a mammalian subject; determining the MHC Class II type of the subject; inducing the generation of antigen-specific regulatory T cells by contacting the isolated CD4+CD25− T cells in a culture vessel with an induction agent for a time period sufficient to generate antigen-specific CD4+CD25+ regulatory T cells; and selecting the CD4+CD25+ antigen-specific regulatory T cells by sorting the cells in the induction culture with a selection agent comprising at least one artificial multimeric MHC Class II/peptide complex that corresponds to the MHC Class II type of the subject.
摘要:
The present invention provides methods and compositions for the diagnosis of hyperproliferative disease and autoimmune disease. Tumor associated antigens, nucleic acids encoding them and antibodies to the tumor associated antigens are provided for the diagnosis of hyperproliferative disease, such as, for example, ovarian cancer, breast cancer, lung cancer, colorectal cancer, and other epithelial cancers, and for the diagnosis of autoimmune disease.
摘要:
Compositions and methods are disclosed that relate to the discovery of citrullinated oligopeptides of 9-14 amino acids or 9-18 amino acids, comprising peptide sequences derived from the polypeptide sequence of human tenascin-C (TNC) containing citrullination-dependent immunological epitopes that, remarkably, are antigen-specifically recognized by both autoantibodies and CD4+ T cells from human subjects having rheumatoid arthritis (RA). The citrullinated TNC (citTNC) oligopeptides are useful for isolating autoantibodies from, and detecting autoantibodies in, biological fluids from subjects having or suspected of having RA. Also described are uses of citTNC oligopeptides to prepare compositions for induction of citTNC autoantigen-specific immunological tolerance, including tolerogens and citTNC-specific Treg cells.
