Nucleotide-binding oligomerization domain-containing protein 2 controls host response to Campylobacter jejuni in Il10-/- mice.

ABSTRACT: Innate signaling-induced antimicrobial response represents a key protective host feature against infectious microorganisms such as Campylobacter species. In this study, we investigated the role of nucleotide-binding oligomerization domain-containing protein 2 (NOD2) in Campylobacter jejuni-induced intestinal inflammation. Specific-pathogen-free Il10(-/-), Nod2(-/-), and Il10(-/-); Nod2(-/-) mice were infected with C. jejuni (10(9) colony-forming units/mouse) 24 hours after a 7-day course of antibiotic treatment. Three weeks later, host responses were determined. The nitric oxide (NO) donor sodium nitroprusside was injected intraperitoneally (2 mg/kg daily) to supplement NO. Although healthy in specific-pathogen-free conditions, Il10(-/-); Nod2(-/-) mice developed severe intestinal inflamma
