Abstract 1. Uropathogenic E. coli adhere to mucosal sites. 2. In the urinary tract, adherence is followed by inflammation, including a mucosal cytokine response. 3. Bacteria activate epithelial cells to secrete IL-6 and IL-8. IL-6 may cause the fever and acute phase response that accompany systemic urinary tract infections. IL-8 may function as a neutrophil chemoattractant. 4. E. coli up-regulate adhesion molecule expression on epithelial cell lines and neutrophil migration through epithelial cell monolayers. This process is inhibited by antibodies to CD18 and ICAM-1. 5. Cytokines released by nonepithelial cells (T cells and monocytes) modify the epithelial cell cytokine response to bacteria.
