T CELL REGULATION

Номер: EP0001596871A2
Принадлежит:

Regulatory T cells (Treg) limit autoimmunity but can also attenuate the magnitude of anti-pathogen and anti-tumor immunity. Understanding the mechanism of Treg function and therapeutic manipulation of Treg in vivo requires identification of Treg selective receptors. A comparative analysis of gene expression arrays from antigen specific CD4+ T cells differentiating to either an effector/memory or a regulatory phenotype revealed Treg selective expression of LAG-3 (CD223), a CD4-related molecule that binds MHC class II. LAG-3 expression on CD4+ T cells correlates with the cells' in vitro suppressor activity, and ectopic expression of LAG-3 on CD4 T cells confers suppressor activity on the T cells. Antibodies to LAG-3 inhibit suppression both in vitro and in vivo. LAG-3 marks regulatory T cell populations and contributes to their suppressor activity.

NONHUMAN MODEL ANIMAL LACKING THE ABILITY TO CONTROL LYMPHOCYTE MIGRATION

Номер: CA0002471432A1
Принадлежит:

It is intended to provide a model animal which is useful in identifying a molecule specifically controlling the mobility of lymphocytes and thus clarifying the pathogenic conditions at the molecular level of immunological diseases such as allergy, autoimmune diseases, GvH and graft rejection, or developing a novel therapy. A model animal such as a DOCK2 knockout mouse, in which the function of controlling lymphocyte migration has been deleted or regulated, is constructed by deleting DOCK2 gene on chromosome. In this DOCK2 knockout mouse, the function of activating Rac to thereby promote the reconstruction of actin cell skeleton, the lymphocyte migration function due to the stimuli with chemokines such as SLC, SDF-1 and BLC, the homing function toward secondary lymph tissues such as spleen, lymph nodes and Peyer~s patch and the function of releasing matured thymus T cells into peripheral blood are injured and, as a result, immune responses are regulated.

Compositions and Methods of Treatment of Black Hemophiliac Patients

It has been determined that most mutations in factor VIII occur in multiple haplotypes, not primarily in one haplotype. The frequencies of mild, moderate, and severe hemophilia did not differ significantly according to the background haplotype. The odds of having inhibitor were significantly higher among patients in the H3+H4 haplotype groups as compared to H1+H2 haplotype groups. This association appears to be independent of the mutation. The results indicate that white hemophiliacs should be treated with Kogenate®. However, it would clearly be of benefit to assess the haplotype of black hemophiliacs prior to prescribing the recombinant FVIII to be used for treatment. It is not essential to determine the actual mutations responsible for the hemophilia prior to prescribing the recombinant FVIII. Also described are transgenic human FVIII animal models. 1.

The invention relates to transgenic non-human animals capable of producing heterologous antibodies and transgenic non-human animals having inactivated endogenous immunoglobulin genes. In one aspect of the invention, endogenous immunoglobulin genes are suppressed by antisense polynucleotides and/or by antiserum directed against endogenous immunoglobulins. Heterologous antibodies are encoded by immunoglobulin genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, one or more transgenes containing sequences of unrearranged heterologous human immunoglobulin heavy chains are introduced into a non-human animal thereby forming a transgenic animal capable of functionally rearranging transgenic immunoglobulin sequences and producing a repertoire of antibodies of various isotypes encoded by human immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized, e.g., by fusing with an immortalizing cell line such as a myeloma or by manipulating such B-cells by other techniques to perpetuate a cell line capable of producing a monoclonal heterologous antibody. The invention also relates to heavy and light chain immunoglobulin transgenes for making such transgenic non-human animals as well as methods and vectors for disrupting endogenous immunoglobulin loci in the transgenic animal.

Transgenic mice depleted in mature t-cells and methods for making transgenic mice

Номер: US5175384A
Принадлежит: Genpharm International Inc

Transgenic mice having a phenotype characterized by the substantial absence of mature T lymphocytes otherwise naturally occurring in said mice. The phenotype is conferred in the transgenic mouse by a transgene contained in at least the precursor stem cell of the T lymphocyte which is depleted. The transgene comprises a DNA sequence encoding a T cell receptor polypeptide variant which inhibits maturation of the T lymphocyte.

Transgenic non-human animals capable of producing heterologous antibodies

Номер: CA2124967C
Принадлежит: Genpharm International Inc

The invention relates transgenic non-human animals capable of producing heterologous antibodies and transgenic non--human animals having inactivated endogenous immunoglobulin genes. In one aspect of the invention, endogenous immunoglob-ulin genes are suppresed by antisense polynucleotides and/or by antiserum directed against endogenous immunoglobulins. He-terologous antibodies are encoded by immunoglobulin genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, one or more transgenes containing sequences of unrearranged heterogolous human immu-noglobulin heavy chains are introduced into a non-human animal thereby forming a transgenic animal capable of functionally rearranging transgenic immunoglobulin sequences and producing a repertoire of antibodies of various isotypes encoded by hu-man immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized, e.g., by fusing with an immortalizing cell line such as a myeloma or by manipulating such B-cells by other techniques to perpetuate a cell line capable of producing a monoclonal heterologous antibody. The invention also relates to heavy and light chain immunog-lobulin transgenes for making such transgenic non-human animals as well as methods and vectors for disrupting endogenous im-munogiobulin loci in the transgenic animal.

Принадлежит: Cell Genesys, Inc.

The subject invention provides non-human mammalian hosts characterized by inactivated endogenous Ig loci and functional human Ig loci for response to an immunogen to produce human antibodies or analogs thereof. The hosts are produced by repetitive transformations of embryonic stem cells by homologous recombination, preferably in conjunction with breeding. Different strategies are employed for recombination of the human loci randomly or at analogous host loci.
