This is a compilation of several short reports delivered at the XII International Congress of Haematology held in Munich, Germany, in August 1970. The sum of these presentations constituted a symposium "The Role of Lymphocytes and Macrophages in the Immunological Response." The breakdown of scholarly attention was about 90% to lymphocytes and 10% to macrophages. Individual papers deal with topics such as cellular cooperation in the induction of immune responses, the role of thymus-derived and bone-marrow-derived cells in immune responses; mediators released from antigen- and phytohemagglutinin-stimulated lymphocytes; the presence of immunoglobulins and complement receptors on lymphocyte membranes; and, finally, several papers on the chemistry of some immunologically relevant structures on lymphocyte and red blood cell membranes.
All papers are very short and require considerable background to understand. It is a bit difficult to say for whom such a symposium was published. It is much too specialized for clinical allergists, immunologists,
