[Effect of monokines induced by Yersinia pestis EV on the functional activity of neutrophils during development of antiplague immunity].

A study was made of the Yersinia pestis EV induced monokine complex influence on neutrophil (Nph) functional activity in the course of antiplague immunity formation. The obtained monokines essentially enhance Nph killing, chemotactic activities and Fc-receptor expression, and stimulate lysosome membrane labilization of these cells. The helper effect of the Y. pestis EV induced monokines on Nph functional activity is more pronounced during the secondary immune response, than in the course of the primary one.
