Nod-like receptors (NLRs) are a family of innate immune receptors that link cytosolic sensing of microbial and danger stimuli to the activation of immune responses. Two NLR family members, Nod1 and Nod2, recognize bacterial peptidoglycan and activate immune responses via NF-κB and MAPK. The function of Nod1 and Nod2 has been largely studied in macrophages, but the role of these receptors in other innate immune cells remains unclear. In this study, we examined the function of Nod1 and Nod2 in innate immune responses of neutrophils. Mice were injected i.p with thioglycollate, and then peritoneal neutrophils were isolated 4h after injection. Tri-DAP and muramyl-dipeptide (MDP) were used as Nod1 and Nod2 agonist, respectively. The level of cytokines (IL-6 and TNF-α) and chemokines (CXCL1 and CCL2) was increased by MDP, but not Tri-DAP in WT neutrophils. Such production of cytokines and chemokines by MDP was abolished in Nod2- and Rip2-deficient neutrophils. MDP also induced the activation of NF-κB and MAPK in WT neutrophils, but not Nod2- and Rip2-deficient cells. Flow cytometry analysis showed that L-selectin shedding was induced by MDP in WT neutrophils, but not in Nod2- and Rip2-deficient cells. MDP and TLR agonists (Pam3CSK4 and LPS) exerted synergistic effect on the production of IL-6 and CXCL1 in neutrophils. Moreover, Nod2 and TLR4 cooperated to produce IL-6, TNF-α, CXCL1, and CCL2 in neutrophils in response to gram-negative bacteria. Our findings suggest that Nod2-Rip2 axis may contribute to innate immune response of neutrophils against bacterial infection.
