[T-and B-lymphocytes in lymphoproliferative syndromes].

Using the various markers of human lymphocytes, it is possible to define, at least roughly, some malignancies of the lymphoid system in terms of their components in T and B cell subpopulations. Furthermore, the study of surface-immune globulins using labelled antisera specific for heavy and light chain classes, has made it possible to define the concept of monoclonal proliferation of B cells. Following a short description of the various interrelationships between B and T lymphocytes, the main lymphoproliferative diseases are briefly described in terms of B or T nature of tumoral cell lines and their bearing on the overall function of the immune apparatus.
