Intestinal Epithelial Cell Response to Clostridium difficile Flagella

Methods Mol Biol. 2016:1476:103-16. doi: 10.1007/978-1-4939-6361-4_8.

Abstract

Clostridium difficile is the bacterium responsible for most antibiotic-associated diarrhea in North America and Europe. This bacterium, which colonizes the gut of humans and animals, produces toxins that are known to contribute directly to damage of the gut. It is known that bacterial flagella are involved in intestinal lesions through the inflammatory host response. The C. difficile flagellin recognizes TLR5 and consequently activates the NF-κB and the MAPK signaling pathways which elicit the synthesis of pro-inflammatory cytokines. Increasing interest on the role of C. difficile flagella in eliciting this cell response was recently developed and the development of tools to study cell response triggered by C. difficile flagella will improve our understanding of the pathogenesis of C. difficile.

Keywords: Clostridium difficile flagella; Flagellin FliC; Innate immune response; MAPK; NF-κB; TLR5 signaling.
