    Abstract: Methods for blocking autoreactive T cell-initiated destruction of tissues in a mammal are provided. In one embodiment, the method comprises administering a purified CD24 polypeptide, a fusion protein comprising such polypeptide, or a biologically active fragment of such polypeptide to a mammalian subject who is suspected of having or predisposed to having an autoimmune disease. In another embodiment, anti-CD24 antibody or anti-CD24 Fab fragments are administered to the subject. In another embodiment, the method comprises administering a CD24 antisense molecule, an expression vector encoding a CD24 antisense molecule, CD24 dsRNAi, or an expression vector encoding CD24 dsRNAi to the subject. The present invention also relates to isolated and purified CD24 fusion proteins employed in the present methods and to transgenic mice that express the human CD24 protein on their T cells and/or their vascular endothelial cells but do not express murine heat shock antigen on any cells.

    Abstract: Provided herein are methods of treating a cancer in a subject comprising administering a FOXP3 protein, a nucleic acid encoding a FOXP3 protein, or an inducing compound which induces FOXP3 protein expression. Methods of altering a phenotype of a cancer cell or tumor cell, methods of inhibiting growth of such cells, and methods of inducing apoptosis of these cells are also provided herein. These methods comprise contacting the cell with a FOXP3 protein, a nucleic acid encoding a FOXP3 protein, or an inducing compound which induces FOXP3 protein expression. Further provided herein are diagnostic methods, comprising comparing the expression or structure of a FOXP3 protein or FOXP3 gene in a test sample to that of a normal or prior sample. A method of screening a test compound for anti-cancer activity comprising administering to cells the test compound and measuring FOXP3 protein or FOXP3 gene expression is moreover provided herein.

  • Publication number: 20090252741
    Abstract: Although results from preclinical studies in animal models have proven the concept for use of anti-CTLA-4 antibodies in cancer immunotherapy, two major obstacles have hindered their successful application for human cancer therapy. First, the lack of in vitro correlates of the anti-tumor effect of the antibodies makes it difficult to screen for the most efficacious antibody by in vitro analysis. Second, significant autoimmune side-effects have been observed In a recent clinical trial. In order to address these two issues, we have generated human CTLA-4 gene knock-in mice and used them to compare a panel of anti-human CTLA-4 antibodies for their ability to induce tumor rejection and autoimmunity. Surprisingly, while all antibodies induced protection against cancer and demonstrated some autoimmune side effects, the antibody that induced the strongest protection also induced the least autoimmune side effects. These results demonstrate that autoimmune disease does not quantitatively correlate with cancer immunity.

  • Patent number: 7504554
    Abstract: The present invention relates to a non-human transgenic animal, particularly a knock in mouse, whose genome comprises a heterologous, chimeric CTLA4 gene. The chimeric CTLA4 gene comprises exon 2 of the human CTLA4 gene, exon 1 and exon 4 of the non-human animal, and exon 3 of the CTLA4 gene of the non-human animal, or preferably, exon 3 of the human CTLA4 gene. The invention also relates to methods by which the transgenic mice are used to screen for monoclonal antibodies or other molecules that enhance immunity to tumors and infectious agents by interacting with the human CTLA4 receptor. The transgenic mice of the present invention are also useful for screening for monoclonal antibodies or other molecules that inhibit autoimmunity and transplant rejection.

  • Publication number: 20090011407
    Abstract: An image data correction apparatus has a motion information acquisition section, a correction section, and a composition section. The motion information acquisition section acquires motion information indicating spatial distribution of the magnitude of motion, in actual space, of a to-be-imaged portion of a subject. Based on the motion information, the correction section performs correction, which is different from correction in a second region, in a first region of image data collected by a scan by magnetic resonance imaging. The composition section composes individual image data of the first region and the second region that are corrected by the correction section.
