Nod2 Is a General Sensor of Peptidoglycan through Muramyl Dipeptide (MDP) Detection

Abstract excerpt

Nod2 activates the NF-kappaB pathway following intracellular stimulation by bacterial products. Recently, mutations in Nod2 have been shown to be associated with Crohn's disease, suggesting a role for bacteria-host interactions in the etiology of this disorder. We show here that Nod2 is a general sensor of peptidoglycan through the recognition of muramyl dipeptide (MDP), the minimal bioactive peptidoglycan motif...
