ABSTRACT
This study describes an in vitro investigation on the role of Pasteurella multocida cells and its isolated protein H and LPS on neutrophil adhesion and migration through bovine endothelial cell monolayers. P. multicoda cells, protein H and LPS increased the adhesion and transmigration of neutrophils through BAEC. The bacteria/cell ratio of 100 for P. multocida, protein H concentration 0.05-0.2 microM and LPS concentration 0.5-1.0 microM respectively, induced the maximum adhesion and transmigration of neutrophils through BAEC. The optimal time of incubation with bacteria or bacterial products was 4-6 h. Our results confirm the role of Gram-negative bacteria and of components of the outer membrane such as protein H or LPS in activating the neutrophils and in promoting the adhesion and cells transmigration from the vessels to the site of inflammation.
