Influence of exposure time on gene expression by human intestinal epithelial cells exposed to Lactobacillus acidophilus

Abstract

Analysis of global temporal gene expression by human intestinal cells when exposed to Lactobacillus acidophilus revealed induction of immune-related pathways and NF-κB target genes after a 1-h exposure, compared to a 4- or 8-h exposure. Additionally, an L. acidophilus derivative expressing covalently bound flagellin resulted in increased induction of il8, cxc1, and cxcl2 compared to the parent L. acidophilus. © 2012, American Society for Microbiology.
