  • Title: Production and diagnostic application of anti-human T-cell antisera.
    Author: Wick G, Ahmad R, Steiner R, Zeilinger M, Wolner E, Mittermayer K, Stacher A.
    Journal: Postgrad Med J; 1976; 52(5 Suppl):20-6. PubMed ID: 825844.
    Abstract:
    This paper is intended to demonstrate the extension of experimental procedures used for the production of anti-chicken T-cell sera to the manufacturing of anti-human T-cell sera. Specific anti-chicken bursa (ABS) and anti-chicken thymus cell sera (ATS) were prepared in turkeys. The in vitro specificity of these sera was assessed by means of immunofluorescence and lymphocytotoxicity tests. The selective immunosuppressive effect of ABS was demonstrated in Obese strain (OS) chickens with spontaneous autoimmune thyroiditis, that of ATS in a skin allograft system. A specific anti-human T-cell serum was prepared by immunizing a horse with fetal human thymus cells. After appropriate exhaustive absorptions this serum was found to react specifically with human T-cells. An anti-T cell globulin (ATG) fraction prepared from the absorbed antiserum was then labelled with FITC for use in direct immunofluorescence tests. The potential diagnostic value of T-cell specific antibodies is discussed.
