  • Title: Contribution of quantitative immunocytology to the study of lymphoid hemopathies.
    Author: Follezou JY, Dighiero G, Roisin JP, Ternynck T, Binet JL.
    Journal: Biomedicine; 1977 Oct; 26(5):330-6. PubMed ID: 71926.
    Abstract:
    Forty-three patients with a lymphoid hemopathy, three with agammaglobulinemia and six normal controls were investigated with regard to their blood lymphocyte membrane-associated light chains. Detection and quantitation of antigenic determinants were performed by means of peroxidase-labeled antibodies. Compared to normal controls, values found in chronic lymphocytic leukemia (CLL) were very low (tenfold decrease). The number of antigenic determinants on lymphoid cells from patients with blast crises supervening in CLL, prolymphocytic leukemia, Waldenström's macroglobulinemia and Burkitt-cell acute leukemia were significantly higher than those seen in patients with CLL. The data obtained in this investigation through quantitative immunocytology constitutes a new parameter for the classification of lymphoid hemopathies and for an approach to their pathogenesis, in particular if the quantity of membrane immunoglobulin correlates with the stage of cell maturation.
