By this method, whole IgG preparations from neutropenic patients and normal controls were invariably found to bind to the surface of granulocytes and a minor proportion of lymphocytes. In contrast. F(ab')2 fragments of IgG from the neutropenic patients failed to bind to the surface of granulocytes. Both whole IgG fractions and F(ab')2 fragments displayed displayed antinuclear antibody activity ruling out the possibility of loss of antibody reactivity during the preparation of F(ab')2 fragments. The neutropenia seen in rheumatoid arthritis with or without splenomegaly thus does not seem to be induced by granulocyte-specific membrane-directed IgG autoantibodies, but rather by a non-specific attachment of IgG most probably in immune complex bound form to Fc gamma receptors on neutrophils which thereby acquire surface properties facilitating removal from the circulating blood cell pool.</p>","PeriodicalId":77653,"journal":{"name":"Acta pathologica, microbiologica, et immunologica Scandinavica.

In order to analyze this phenomenon the effect of albumin on PMN migration in a Boyden chamber towards various chemotactic agents was examined. On attraction with low molecular weight chemotactic factors (a culture filtrate of E. coli (BCF)) or the synthetic peptide N-Formyl-Methionyl-Leucyl-Phenylalanine (F-Met-Leu-Phe) albumin enhanced the migration of PMN. In contrast, albumin did not enhance the migration towards casein, a high molecular weight chemotactic factor, except at very low concentrations. In a direct visual assay, albumin was found to impair PMN spreading on a polystyrene Petri dish. In the presence of BCF or F-Met-Leu-Phe cell spreading remained inversely related to the concentration of albumin, while addition of casein again eliminated the influence of albumin. The effect of albumin on the interaction of PMN with a substrate was studied by measuring the superoxide anion (02-) release by PMN sedimenting on a micropore filter. The 02- release triggered by this stimulus of the PMN membrane was inversely correlated to the concentration of albumin. These results show that one mechanism of the enhancing effect of albumin on PMN migration is to diminish adhesion of the cells to the substratum, so that it remains reversible. It is suggested that the term chemokinesis is equivocal. The chemokinetic activity of chemotactic factors would be the result of specific stimulation of PMN locomotion. In contrast, the chemokinetic activity of albumin is due to changes of the physico-chemical environment which support PMN locomotion.</p>","PeriodicalId":77653,"journal":{"name":"Acta pathologica, microbiologica, et immunologica Scandinavica.
