Title: Rosetting, phagocytosis and immune red cell damage
Abstract: Summary Observations on rosette formation of red blood cells sensitized with a known number of IgG1 or IgG3 polyclonal or monoclonal anti-Rh(D) antibodies with monocytes, lymphocytes and granulocytes have provided further evidence for the essential role of monocytes/macrophages in red cell destruction. The rosette test with monocytes and the monocyte-monolayer assay (MMA) have confirmed, on a quantitative basis, the greater binding ability of IgG3 than of IgG1 antibodies and that the rate of interaction with red cells increases in proportion to the level of their sensitization. These observations have suggested that the MMA may reflect haemolysis in vivo. It has appeared that the MMA is suitable for assessing haemolysis in many cases of haemolytic disease of the newborn, in autoimmune haemolytic anaemia and in patients with alloantibodies to be transfused. Since in individual cases a clear correlation between the MMA results and haemolysis in vivo was not observed, the factors which may influence such discrepancies are discussed.
