  • Title: Mononuclear cells in renal allografts. Correlation with peripheral blood T lymphocyte subpopulations and graft prognosis.
    Author: van Es A, Meyer CJ, Oljans PJ, Tanke HJ, van Es LA.
    Journal: Transplantation; 1984 Feb; 37(2):134-9. PubMed ID: 6364496.
    Abstract:
    Cellular infiltrates in 20 renal allograft biopsies taken at the time of acute rejection episodes were analyzed with antibodies reactive with monocytes (BRL antihuman monocyte monoclonal antibody), T lymphocyte subpopulations (OKT- and Leu-series of monoclonal antibodies), and B lymphocytes (heterologous antihuman IgM antibodies). For demonstration of the various mononuclear cells, an indirect immunoperoxidase technique was used. The number of monocytes in the infiltrates varied from 10-20%; the number of B lymphocytes was always below 10%. The T lymphocytes accounted for 50-90% of the total number of mononuclear cells. The OKT4/OKT8 ratios for the T lymphocytes in the graft infiltrates were correlated with the peripheral blood OKT4/OKT8 ratios measured by indirect fluorescence and flow cytometry. The OKT4/OKT8 ratios for perivascular infiltrates correlated far better with peripheral blood OKT4/OKT8 ratios (r = 0.72) than did the OKT4/OKT8 ratios for interstitial infiltrates (r = 0.58). Low or inverted OKT4/OKT8 ratios and low or inverted Leu 3a/Leu 2a ratios were associated with a high risk of irreversible graft rejection (P less than 0.001 for perivascular infiltrates).
