Abstract: The present invention is directed to a method of identifying CD4+ T cell antigens as well as to antigens which were identified by such a method. The present invention further is directed to the application of those identified antigens in medicine.

Abstract: Provided are compositions and methods for inhibiting cell growth. The cells that are targeted by the compositions and methods of the invention express an antigen, a mimotope of the antigen, or a CXCR4 chemokine receptor. The method entails administering to an individual a polynucleotide encoding an immunoglobulin Fc and an antigen expressed by the cells or a mimotope of the antigen. The method also involves administering to the individual a composition which contains a polynucleotide encoding an immunoglobulin Fc and an antagonist peptide of a CXCR4 chemokine receptor expressed by the cells. Also provided are proteins encoded by the polynucleotides.

Abstract: Disclosed are compositions and methods for detecting cells or tissue comprising a peptide antigen presented in the context of an MHC or HLA complex. The invention has a wide range of applications including providing a highly sensitive method for detecting cancer cells.

Abstract: A method of generating a CD4+FoxP3+ Treg cell, the method includes administering at least one complement antagonist to a naive CD4+ T cell at an amount effective to substantially inhibits C3a receptor (C3aR) and/or C5a receptor (C5aR) signal transduction in the CD4+ T cell, induce TGF-?1 expression of the CD4+ T cell, and induce differentiation of the of the naive CD4+ T cell into a CD4+FoxP3+ Treg cell.

Abstract: The present invention relates to a composition containing PIAS3 as an active ingredient for the prevention or treatment of cancer or immune disease. More specifically, the present invention relates to a composition containing the PIAS3 gene or an expressing protein thereof as an active ingredient for the prevention or treatment of cancer or immune disease, to an immunosuppressant composition, to a method for reducing or inhibiting undifferentiated T cells into Th17 cells using the PIAS3 gene or an expressing protein thereof, and to a method for activating regulatory T cells.

Abstract: Highly potent dendritic cells are generated in vivo or ex vivo by exposing precursor cells to an effective dose of IL-32.

Abstract: The present invention encompasses methods, and kits for the isolation and expansion of T regulatory cells having the CD45RA+ phenotype, including such cells from human umbilical cord blood.

Abstract: The present invention provides TCRs having high affinity. The TCR binds to SLYNTVATL (SEQ ID NO:16)-HLA-A*0201 with a KD of less than or equal to 1 ?M and/or an off-rate (koff) of 1×10?3 S?1 or slower using Surface Plasmon Resonance. The TCRs are non-native, isolated or recombinant. The TCRs are useful, either alone, or with a therapeutic agent, for targeting HIV infected cells that present the SLYNTVATL (SEQ ID NO:16)-HLA-A*0201 complex.

Abstract: The present invention relates to the use of immunogenic peptides comprising a T-cell epitope derived from an allograft antigen and a redox motif such as C-(X)2-[CST] or [CST]-(X)2-C in the prevention and/or treatment of allograft rejection and in the manufacture of medicaments therefore.

Abstract: The invention provides compositions and methods of treating various conditions, including tumors, with compositions comprising dendritic cells expressing exogenous chemokines.

Abstract: The present invention provides methods and compositions for converting non-Tregs into Tregs. The converted Tregs are referred to as inducible Tregs (iTregs). The iTregs are useful for preventing, suppressing, blocking or inhibiting an immune response. For example the iTregs are useful for preventing rejection of a transplanted tissue in a human or other animal host, or protecting against graft vs host disease. The iTregs can also be used to treat autoimmune diseases.

Abstract: The present invention relates to methods for isolating human forkhead box P3 (Foxp3+) CD4+ regulatory T cells (herein referred to a Foxp3+ Treg cells) from a sample containing (i) peripheral blood mononuclear cells (PBMCs), (ii) a lymphocyte containing fluid, or (iii) a lymphocyte containing tissue, a kit for isolating human Foxp3+ Treg cells, and the use of anti-CD49d antibody for the isolation of human Foxp3+ Treg cells.

Abstract: The invention relates to the regulation of the immune system, and in particular to the finding that the CLEC9a molecule is a marker for dendritic cells which are capable of cross-presenting extracellular antigens via the MHC class I pathway. This makes them particularly suitable for generation of cytotoxic T lymphocyte responses. Materials and methods are provided both for the induction of immune responses against target antigens, and for the inhibition or suppression of undesirable immune responses in which these cells are involved.

Abstract: The present invention encompasses methods, and kits for the isolation and expansion of T regulatory cells having the CD45RA+ phenotype, including such cells from human umbilical cord blood.
