Bacterial pathogens can induce an inflammatory response from epithelial tissues
due to secretion of the pro-inflammatory chemokine interleukin-8 (IL-8). Many
bacterial pathogens manipulate components of the focal complex (FC) to induce
signalling events in host cells. We examined the interaction of several bacterial
pathogens with host cells, including Campylobacter jejuni, to determine if the FC
is required for induction of chemokine signalling in response to bacterial
pathogens. Our data indicate that secretion of IL-8 is triggered by C. jejuni,
Helicobacter pylori and Salmonella enterica serovar Typhimurium in response to
engagement of ?1 integrins. Additionally, we found that the secretion of IL-8
from C. jejuni infected epithelial cells requires FAK, Src and paxillin, which in
turn are necessary for Erk 1/2 recruitment and activation. Targeting the FC
component paxillin with siRNA prevented IL-8 secretion from cells infected with
several bacterial pathogens, including C. jejuni, Helicobacter pylori, Salmonella
enterica serovar Typhimurium, Staphylococcus aureus, Pseudomonas aeruginosa, and
Vibrio parahaemolyticus. Our findings indicate that maximal IL-8 secretion from
epithelial cells in response to bacterial infection is dependent on the FC. Based
on the commonality of the host response to bacterial pathogens, we propose that
the FC is a signalling platform for an epithelial cell response to pathogenic
organisms.
