Abstract: Provided herein are recombinant miniature swine expressing human CD47 in a tissue specific fashion. Also provided are kidneys isolated from a miniature swine, wherein the glomeruli of the kidney express human CD47 at a level higher than the level of human CD47 expression in the tubules of the kidney. Furthermore, provided herein are methods of transplanting such swine kidneys with glomeruli-specific expression of human CD47 from recombinant miniature swine into human recipients. In certain aspects, provided herein are methods of transplantation comprising transplanting hematopoietic stem cells expressing human CD47 from a first donor animal (e.g., a miniature swine) and a kidney expressing human CD47 in the glomeruli from a second donor animal (e g., a miniature swine) to a recipient (e.g., a human recipient).

Abstract: Transgenic swine that express human coagulation factors, e.g., human coagulation factor VII, and/or one or more of human coagulation factors II, X and XII, and do not express the corresponding porcine coagulation factor or factors, as well as cells, tissues and organs derived therefrom, and their use in transplantation procedures.

Abstract: Mutant forms of human CTLA4, and their use, e.g., in xenotransplantation.

Abstract: Methods of preparing and porcine cells, organs and tissues that have reduced immunogenicity, e.g., for transplant into humans, e.g., for the treatment of burn injuries.

Abstract: IL-2 fusion toxins, e.g., bivalent-IL2 fusion toxins, and methods of use thereof.

Abstract: This invention relates to recombinant CTLA-4 proteins, e.g., soluble CTLA-4 or CTLA-4 fusion toxins, and methods for making and using them.

Abstract: Anti-human chemokine (C—C motif) Receptor 4 immunotoxins and methods of use thereof, e.g., for depleting Tregs as an immunotherapy for the treatment of cancer; for the treatment of cancers associated with CCR4+ tumor cells such as skin homing cutaneous T cell lymphoma, adult T cell leukemia/lymphoma, and acute T-cell lymphoblastic leukemia; and for the depletion of CCCR4+ Th2 cells for the treatment of allergy-related conditions such as asthma.

Abstract: A method to determine the optimal administration protocol of allogeneic donor tissue to treat a disease in a human, using an animal model of human disease.

Abstract: The invention provides a swine which is homozygous for a major histocompatibility complex haplotype and at least 60% homozygous at all other genetic loci and such animal is propagatable, and a cell or an organ derived therefrom. The invention also provides a method for providing a swine which is homozygous at swine leukocyte antigens (SLA) A, B, C, DR, and DQ, and in which at least 60% of all other genetic loci are homozygous, as well as a method of inducing tolerance in a recipient mammal of a first species to a graft from a donor mammal of a second species.

Abstract: The invention provides methods for restoring or inducing immunocompetence, the methods including the step of introducing donor thymic tissue into the recipient. The invention also provides methods for inducing tolerance in a recipient including introducing donor thymic tissue into the recipient. The invention further provides methods of inducing tolerance including administering to the recipient a short course of help reducing treatment or administering a short course and methods of prolonging the acceptance of a graft by administering a short course of an immunosuppressant.

Abstract: Methods of promoting tolerance and inhibiting NK cell mediated attack in a human recipient to a swine graft are disclosed The methods include introducing into the recipient a swine hematopoietic stem cell which has been transformed with a transgene encoding a human MHC class I protein that inhibits recipient NK cell mediated attack.

Abstract: Transgenic swine in which the normal expression of &agr;(1,3) galactosyltransferase is prevented in at least one organ of tissue type. The absence or inactivation of this enzyme prevents the production of carbohydrate moieties having the distinctive terminal Gal&agr;1-3Gal&bgr;1-4GlcNAc epitope that is a significant factor in xenogeneic, particularly human, transplant rejection of swine grafts.
