Nucleotide-Binding Oligomerization Domain 2 Signaling Promotes Hyperresponsive Macrophages and Colitis in IL-10–Deficient Mice

Nucleotide-binding oligomerization domain 2 signaling promotes hyperresponsive macrophages and colitis in IL-10-deficient mice.

IL-10 contributes to the maintenance of intestinal homeostasis via the regulation of inflammatory responses to enteric bacteria. Loss of IL-10 signaling results in spontaneous colitis in mice and early onset enterocolitis in humans. Nucleotide-binding oligomerization domain (NOD) 2 is an intracellular receptor of bacterial peptidoglycan products, and, although NOD2 mutations are associated with...

Muramyl dipeptide activation of nucleotide-binding oligomerization domain 2 protects mice from experimental colitis.

The mechanisms underlying the susceptibility of individuals with caspase recruitment domain 15 (CARD15) mutations and corresponding abnormalities of nucleotide-binding oligomerization domain 2 (NOD2) protein to Crohn disease are still poorly understood. One possibility is based on previous studies showing that muramyl dipeptide (MDP) activation of NOD2 negatively regulates TLR2 responses and th...

Nucleotide-Binding Oligomerization Domain

association of nucleotide-binding oligomerization domain receptors with peptic ulcer and gastric cancer

host innate immunity can affect the clinical outcomes of helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and malt lymphoma. nucleotide binding oligomerization domain (nod)-1 and -2 are two molecules of innate immunity which are involved in the host defense against h. pylori . this study aimed to evaluate the effect of the expression level of nod1 and n...

Microbiota Composition and Immune Responses During Campylobacter Jejuni Infection in Conventionally Colonized IL-10–/– Mice Lacking Nucleotide Oligomerization Domain 2

Host immune responses are pivotal for combating enteropathogenic infections. We here assessed the impact of the innate receptor nucleotide oligomerization domain protein 2 (NOD2) in murine Campylobacter jejuni-infection. Conventionally colonized IL-10-/- mice lacking NOD2 and IL-10-/- controls were perorally challenged with C. jejuni strain 81-176 and displayed comparable pathogenic colonizatio...
