Correction of equine severe combined immunodeficiency by bone marrow transplantation. A 32-day-old horse with severe combined immunodeficiency was transplanted with equine bone marrow cells in an attempt to establish immunologic responsiveness. A histocompatible, mixed-leukocyte-culture-nonreactive, sex-matched, full sibling was used as the donor. Recipient total lymphocyte count, T and B lymphocyte numbers, and response of peripheral blood mononuclear cells to phytolectin stimulation increased by 14 days following transplantation. Circulating lymphocytes exceeded 1000 cells/microliter blood by 40 days posttransplantation, and by 170 days following transplantation, T and B lymp...
Major histocompatibility locus in the Arabian horse. Combined immunodeficiency disease (CID) is a genetic disorder of T and B lymphocyte production which results in a nonfunctional immune system. It is inherited as an autosomal recessive trait and has been reported in humans and in horses of the Arabian breed. Arabian horses known to have the CID gene and horses of unknown carrier status were tested using a microlymphocytotoxicity technique. Computer chi 2 analysis distinguished six serologically defined specificities. The study of unrelated horses and a limited number of families showed that the specificities behave as codominant alleles segreg...
Equine leukocyte antigen system. II. Serological and mixed lymphocyte reactivity studies in families. Mono- and oligospecific lymphocytotoxic alloantibodies from primiparous mares were tested on cells from horse families of various breeds in the two-step microcytotoxicity assay. The results showed that the detected antigens were inherited co-dominantly and autosomally as simple Mendelian traits. The membrane antigens showed different linkage with one or more other antigens and seem to be coded by a limited number of loci (at least three) from one chromosome. In the families tested one recombinant for the serologically defined antigens was recognized. The mixed leukocyte reactions of cells from...
Suppressor T cells in tolerance to deaggregated horse anti-human thymocyte globulin in man. To understand the mechanism by which deaggregated horse anti-human thymocyte globulin (dATG) fails to induce untoward immunological reactions in man, three patients who received ATG and two patients who received dATG were studied for evidence of sensitization or tolerance to the foreign globulin. The ATG but not the dATG recipients developed allergic or serum sickness reactions; antihorse serum antibody could be detected in their serum and their blood cells proliferated in vitro in the presence of horse serum and secreted antihorse serum antibodies (P less than 0.001). Tolerance of the dATG re...
Mixed lymphocyte culture responses in combined immunodeficiency of horses. Combined immunodeficiency in horses is a genetic disorder in which there is a defect in the production of committed B and T lymphocytes. In this study, peripheral blood mononuclear leukocytes from foals with combined immunodeficiency were examined for their capacity to stimulate and respond in one-way mixed lymphocyte cultures. Irradiated cells from combined immunodeficient foals were uniformly capable of stimulating cells from unrelated horses. However, none were able to respond to allogeneic stimulation. Examination of cells from known carrier horses revealed no difference in capacity to sti...
The preparation and testing of antihuman lymphoblast globulin for clinical use. Antibodies to cultured human lymphoblasts were raised in horses using a schedule employing both subcutaneous and intravenous routes of injection. Plasma from groups of horses was pooled and the IgG prepared from each pool was tested extensively for safety and immunosuppressive efficacy in vitro and in vivo. On the basis of the results of skin grafting in monkeys, only globulins derived from the first main bleeds were blended to produce a bulk for clinical use. One early pool of globulin was discarded because when undiluted, it was lethal in monkeys by the intravenous route, and another pool wa...
Standardized horse antihuman lymphocyte globulin for clinical use. Multiple injections of horses with the membrane-microsome fraction from human thymocytes plus Freund's adjuvant gave rise to antithymocyte membrane serum with the immunosuppressive activity located in the γ2 region. Use of lymphoblast membrane-microsome fraction as antigen did not reduce the level of absorption required. Batch purification with QAE-Sephadex combined with ammonium sulfate fractionation gave 100% pure γG-globulins in good yield with reduced γ1-globulin content. The antithymocyte membrane globulin prolonged skin allografts in the cynomolgus monkey, chimpanzee, and man, showed ...
The development and distribution of antilymphocytic and other antibodies in horses immunized with human lymphoid antigens. Serum samples were obtained at regular intervals from groups of horses immunized with peripheral blood lymphocytes, thoracic duct lymphocytes, or peripheral blood lymphocyte membranes. These sera were separated into the classical 19 S, 10 S, 7 S, and 4.5 S fractions by Sephadex gel filtration and the antibody activity (antilymphocytic or otherwise) of these fractions, and of the original sera, was assessed by standard in vitro procedures. The antilymphocytic activities measured included lymphocyte agglutination, lysis, and transformation. The other antibodies assayed were platelet and erythroc...
