Interaction of extracellular vesicles of Bacteroides gingivalis W50 with human polymorphonuclear leucocytes.

The effects of B. gingivalis W50 extracellular vesicles (ECV) on neutrophil chemotaxis and viability were assessed and compared with those of whole cells and the extracellular non-dialysable soluble protein (EP) fraction. None of the fractions tested, including soluble fractions derived from cells and ECV by sonication, induced neutrophil chemotaxis. Only… CONTINUE READING
