Intestinal epithelial cells as watchdogs for the natural immune system

Trends Microbiol. 1995 Mar;3(3):118-20. doi: 10.1016/s0966-842x(00)88894-0.

Abstract

Intestinal epithelial cells secrete a spectrum of chemoattractant and proinflammatory cytokines after invasion by bacteria. We suggest the novel concept that epithelial cells not only act as a mechanical barrier to invasive bacteria, but that they also signal the presence of invasive pathogens to the mucosal immune and inflammatory cells.
