title: [Comparative evaluation of the neutrophilokine-inducing activity of Yersinia pestis EV and Escherichia coli lipopolysaccharides].
abstract: As shown in this study, neutrophilokine-inducing capacity of Y. pestis EV lipopolysaccharide (LPS) was not inferior to, and in secondary immune response even exceeded, that of E. coli LPS. Neutrophilokines synthesized under the action of the former preparation produced greater influence on the inhibition of macrophage migration from the focus of infection, the phagocytic activity of these cells (in secondary immune response) and the labilization of the lysosomic membranes of macrophages than neutrophilokines induced by E. coli LPS. Only in primary immune response the digestive capacity of macrophages was more actively stimulated by neutrophilokines induced by E. coli LPS. Both preparations did not induce the secretion of neutrophilokines regulating the expression of Fc-receptors on the surface of macrophages.
