Role of epithelial interleukin-8 (IL-8) and neutrophil IL-8 receptor A in Escherichia coli-induced transuroepithelial neutrophil migration
(1997) In Infection and Immunity 65(8). p.3451-3456- Abstract
- Escherichia coli stimulates neutrophil migration across human uroepithelial cell layers. This study investigated the role of the neutrophil chemokine interleukin-8 (IL-8) in this process. E. coli and IL-1alpha stimulated urinary tract epithelial layers to secrete IL-8 and induced transepithelial neutrophil migration. Anti-IL-8 antibody reduced neutrophil migration across epithelial cell layers, indicating a central role for this chemokine in the migration process. Furthermore, addition of recombinant IL-8 to unstimulated cell layers was sufficient to induce migration. The IL-8 dependence of neutrophil migration was maintained after removal of soluble IL-8 by washing of the cell layers. Flow cytometry analysis with fluorescein... (More)

Furthermore, addition of recombinant IL-8 to unstimulated cell layers was sufficient to induce migration. The IL-8 dependence of neutrophil migration was maintained after removal of soluble IL-8 by washing of the cell layers. Flow cytometry analysis with fluorescein isothiocyanate-labelled IL-8 confirmed IL-8's ability to bind to the epithelial cell surface. Indirect immunofluorescence with confocal laser scanning microscopy showed that IL-8 associated with the epithelial cell layers. Prior incubation of neutrophils with antibodies to IL-8 receptor A (IL-8RA) reduced neutrophil migration. Anti-IL-8 RB antibody had no effect on neutrophil migration. These results demonstrate that IL-8 plays a key role in E. coli- or IL-1alpha-induced transuroepithelial migration and suggest that epithelial cell-produced IL-8 interacts with IL-8RA on the neutrophil surface.
