Abstract
Vitamin D plays a crucial role in modulating the innate immune response by interacting with its intracellular receptor, VDR. In this review, we address vitamin D/VDR signaling and how it contributes to the regulation of intestinal and respiratory microbiota. We additionally review some components of the innate immune system, such as the barrier function of the pulmonary and intestinal epithelial membranes and secretion of mucus, with their respective modulation by vitamin D. We also explore the mechanisms by which this vitamin D/VDR signaling mounts an antimicrobial response through the transduction of microbial signals and the production of antimicrobial peptides that constitute one of the body’s first lines of defense against pathogens. Additionally, we highlight the role of vitamin D in clinical diseases, namely inflammatory bowel disease and acute respiratory distress syndrome, where excessive inflammatory responses and dysbiosis are hallmarks. Increasing evidence suggests that vitamin D supplementation may have potentially beneficial effects on those diseases.

Abstract
Retinoblastoma (RB) is prone to delayed diagnosis or treatment and has an increased likelihood of metastasizing. Thus, it is crucial to perform an effective imaging examination and provide optimal treatment of RB to prevent metastasis. Nanoparticles that support diagnostic imaging and targeted therapy are expected to noninvasively integrate tumor diagnosis and treatment. Herein, we report a multifunctional nanoparticle for multimodal imaging-guided low-intensity focused ultrasound (LIFU)/immunosynergistic RB therapy. Magnetic hollow mesoporous gold nanocages (AuNCs) conjugated with Fe3O4 nanoparticles (AuNCs-Fe3O4) were prepared to encapsulate muramyl dipeptide (MDP) and perfluoropentane (PFP). The multimodal imaging capabilities, antitumor effects, and dendritic cell (DC) activation capacity of these nanoparticles combined with LIFU were explored in vitro and in vivo. The biosafety of AuNCs-Fe3O4/MDP/PFP was also evaluated systematically. The multifunctional magnetic nanoparticles enhanced photoacoustic (PA), ultrasound (US), and magnetic resonance (MR) imaging in vivo and in vitro, which was helpful for diagnosis and efficacy evaluation. Upon accumulation in tumors via a magnetic field, the nanoparticles underwent phase transition under LIFU irradiation and MDP was released. A combined effect of AuNCs-Fe3O4/MDP/PFP and LIFU was recorded and verified. AuNCs-Fe3O4/MDP/PFP enhanced the therapeutic effect of LIFU and led to direct apoptosis/necrosis of tumors, while MDP promoted DC maturation and activation and activated the ability of DCs to recognize and clear tumor cells. By enhancing PA/US/MR imaging and inhibiting tumor growth, the multifunctional AuNC-Fe3O4/MDP/PFP nanoparticles show great potential for multimodal imaging-guided LIFU/immunosynergistic therapy of RB. The proposed nanoplatform facilitates cancer theranostics with high biosafety.

Abstract
Both toll-like receptors (TLRs) and nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs) induce a tightly regulated inflammatory response at risk of causing tissue damage, depending on the effectiveness of ensuing negative feedback regulatory mechanisms. Cross-regulation between TLRs, NLRs, and cytokine receptors has been observed. However, the cross-regulation between interleukin-1 (IL-1) receptors and NOD2 is not completely understood. In this study, we found that IL-1α/β increased NOD2-induced inflammatory response in human monocytic THP1 cells, peripheral blood mononuclear cells (PBMCs), mouse macrophage RWA264.7 cells and spleen cells, and in an in vivo experiment. IL-1α/β pre-treatment induced the production of CXC chemokines, including growth-regulated oncogene (GRO)-α, GRO-β, and IL-8, and proinflammatory cytokines, including IL-1β, IL-6, and TNFα, which are induced by the activation of NOD2, in a dose- and time-dependent manner. However, pre-treatment with the NOD2 ligand muramyl dipeptide (MDP) did not up-regulate the expression of cytokines induced by IL-1α/β re-treatment. IL-1β treatment increased the expression of A20, which is an important inhibitor of the innate immune response. However, the overexpression of A20 failed to inhibit MDP-induced cytokine production, suggesting that A20 had no effects on the NOD2-induced immune response. In addition, IL-1α/β increased the expression of NOD2 and its downstream adaptor RIP2, and IL-1α/β pre-treatment increased MDP-induced activation of mitogen-activated protein kinases (MAPKs), including ERK, JNK, and P38, which contributed to MDP-induced cytokine production. Based on these results, IL-1α/β promote the NOD2-induced immune responses by enhancing MDP-induced activation of MAPK signaling pathways.

Abstract
AIMS NOD2 and CD1d play a key role in innate immunity by recognizing conserved molecular patterns of pathogens. While NOD2-/- and CD1d-/- mice display structural and functional alterations in Paneth cells, animal studies have reported no impact of NOD2 or CD1d deficiency on experimental colitis. NOD2 mutations increase the susceptibility to inflammatory bowel diseases and the CD1d bound to α-galactosylceramide [α-GalCer] alleviates intestinal inflammation. We evaluated the effect of CD1d modulation on experimental colitis in NOD2-/- mice. METHODS The effect of CD1d augmentation and depletion in NOD2-/- mice was assessed in a dextran sodium sulphate [DSS]-induced colitis model via administration of α-GalCer and construction of NOD2-/-CD1d-/- mice. The structural and functional changes in Paneth cells were evaluated using transmission electron microscopy and pilocarpine administration. Colitogenic taxa were analysed in the faeces of NOD2-/-CD1d-/- mice using 16S rRNA gene sequencing. RESULTS In NOD2-/- mice, α-GalCer alleviated and CD1d depletion [NOD2-/-CD1d-/- mice] aggravated colitis activity and histology compared with co-housed littermates NOD2-/-, CD1d-/- and wild-type mice after administration of 3% DSS. In NOD2-/-CD1d-/- mice, the ultrastructure and degranulation ability of secretary granules in Paneth cells were altered and the intestinal microbial composition differed from that of their littermates. Faecal microbiota transplantation [FMT] with NOD2-/-CD1d-/- mice faeces into wild-type mice aggravated DSS-induced colitis, while FMT with wild-type mice faeces into NOD2-/-CD1d-/- mice alleviated DSS-induced colitis. Acetatifactor muris was identified only in NOD2-/-CD1d-/- mice faeces and the oral gavage of A. muris in wild-type mice aggravated DSS-induced colitis. CONCLUSION CD1d modulates colonic inflammation in NOD2-/- mice by altering the intestinal microbial composition comprising A. muris.

Abstract
Previous studies have shown that inhibition of receptor-interacting serine/threonine kinase (RICK) (also known as RIP2) results in amelioration of experimental colitis. This role has largely been attributed to nucleotide-binding oligomerization domain 2 (NOD2) signaling since the latter is considered a major inducer of RICK activation. In this study, we explored the molecular mechanisms accounting for RICK-mediated inhibition of inflammatory bowel disease (IBD). In an initial series of studies focused on trinitrobenzene sulfonic acid (TNBS)-colitis and dextran sodium sulfate (DSS)-colitis we showed that down-regulation of intestinal RICK expression in NOD2-intact mice by intra-rectal administration of a plasmid expressing RICK-specific siRNA was accompanied by down-regulation of pro-inflammatory cytokine responses in the colon and protection of the mice from experimental colitis. Somewhat surprisingly, intra-rectal administration of RICK-siRNA also inhibited TNBS-colitis and DSS-colitis in NOD2-deficient and in NOD1/NOD2-double deficient mice. In complementary studies of humans with IBD we found that expression of RICK, cellular inhibitor of apoptosis protein 2 (cIAP2) and downstream signaling partners were markedly increased in inflamed tissue of IBD compared to controls without marked elevations of NOD1 or NOD2 expression. In addition, the increase in RICK expression correlated with disease activity and pro-inflammatory cytokine responses. These studies thus suggest that NOD1- or NOD2-independenent activation of RICK plays a major role in both murine experimental colitis and human IBD.

Abstract
NOD-like receptors (NLRs) play a key role in the innate immune system, acting as a second line of surveillance against pathogens. NLRs detect particular bacteria that have gained access to the cytoplasm, evading recognition by other pattern recognition receptors, such as Toll-like receptors. It has been demonstrated that coding sequence-single nucleotide polymorphisms may alter the ligand recognition ability of NLRs, affecting their pathogen-sensing function. However, there have been no data relating to the identification and functional analysis of SNPs in porcine NLR promoters. We examined the promoter sequences of the porcine NOD1 and NOD2 genes with the aim to identify and to evaluate the effect of genetic variations on promoter activity. Six SNPs in NOD1 and three SNPs in NOD2 were identified. Luciferase reporter gene assays showed significant differences in promoter activity between allele variants of NOD1 -920G>A (NC_010460.4:g.42431413G>A) and NOD2 -1670G>A (NC_010448.4:g.34169122T>C) SNPs. The results suggest that promoter polymorphisms could modify the expression levels of porcine NOD1 and NOD2 genes.

Abstract
Nucleotide-binding oligomerization domain (NOD) 1 and NOD2 are pattern-recognition receptors responsible for sensing fragments of bacterial peptidoglycan known as muropeptides. Stimulation of innate immunity by systemic or local administration of NOD1 and NOD2 agonists is an attractive means to prevent and treat infectious diseases. In this review, we discuss novel data concerning structural features of selective and non-selective (dual) NOD1 and NOD2 agonists, main signaling pathways and biological effects induced by NOD1 and NOD2 stimulation, including induction of pro-inflammatory cytokines, type I interferons and antimicrobial peptides, induction of autophagy, alterations of metabolism. We also discuss interactions between NOD1/NOD2 and Toll-like receptor agonists in terms of synergy and cross-tolerance. Finally, we review available animal data on the role of NOD1 and NOD2 in protection against infections, and discuss how these data could be applied in human infectious diseases.

Abstract
Transient Receptor Potential Melastatin-8 (TRPM8) reportedly plays a fundamental role in a variety of processes including cold sensation, thermoregulation, pain transduction and tumorigenesis. However, the role of TRPM8 in inflammation under cold conditions is not well known. Since cooling allows the convergence of primary injury and injury-induced inflammation, we hypothesized that the mechanism of the protective effects of cooling might be related to TRPM8. We therefore investigated the involvement of TRPM8 activation in the regulation of inflammatory cytokines. The results showed that TRPM8 expression in the mouse hypothalamus was upregulated when the ambient temperature decreased; simultaneously, tumor necrosis factor-alpha (TNFα) was downregulated. The inhibitory effect of TRPM8 on TNFα was mediated by nuclear factor kappa B (NFκB). Specifically, cold stress stimulated the expression of TRPM8, which promoted the interaction of TRPM8 and NFκB, thereby suppressing NFκB nuclear localization. This suppression consequently led to the inhibition of TNFα gene transcription. The present data suggest a possible theoretical foundation for the anti-inflammatory role of TRPM8 activation, providing an experimental basis that could contribute to the advancement of cooling therapy for trauma patients.

Abstract
Tumor suppression that is mediated by oncogene-induced senescence (OIS) is considered to function as a safeguard during development of pancreatic ductal adenocarcinoma (PDAC). However, the mechanisms that regulate OIS in PDAC are poorly understood. Here, we have determined that nuclear RelA reinforces OIS to inhibit carcinogenesis in the Kras mouse model of PDAC. Inactivation of RelA accelerated pancreatic lesion formation in Kras mice by abrogating the senescence-associated secretory phenotype (SASP) gene transcription signature. Using genetic and pharmacological tools, we determined that RelA activation promotes OIS via elevation of the SASP factor CXCL1 (also known as KC), which activates CXCR2, during pancreatic carcinogenesis. In Kras mice, pancreas-specific inactivation of CXCR2 prevented OIS and was correlated with increased tumor proliferation and decreased survival. Moreover, reductions in CXCR2 levels were associated with advanced neoplastic lesions in tissue from human pancreatic specimens. Genetically disabling OIS in Kras mice caused RelA to promote tumor proliferation, suggesting a dual role for RelA signaling in pancreatic carcinogenesis. Taken together, our data suggest a pivotal role for RelA in regulating OIS in preneoplastic lesions and implicate the RelA/CXCL1/CXCR2 axis as an essential mechanism of tumor surveillance in PDAC.

NOD2 pathway via RIPK2 and TBK1 is involved in the aberrant catabolism induced by T-2 toxin in chondrocytes. Osteoarthritis Cartilage 2015; 23:1575-85. [PMID: 25917637 DOI: 10.1016/j.joca.2015.04.016] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2014] [Revised: 03/27/2015] [Accepted: 04/15/2015] [Indexed: 02/02/2023]
Abstract
OBJECTIVE This study aimed to identify the key intracellular pattern recognition receptor (PRR) and its role in the unbalanced extracellular matrix gene expressions of chondrocytes treated by T-2 toxin, a potential etiological factor for cartilage damages. DESIGN Differential expressions of intracellular PRRs after T-2 toxin treatment were screened by RT-qPCR in chondrocytes. RNAi was used to knockdown the expression of NOD2 and its two downstream signal molecules, RIPK2, and TBK1, for observing the effects of NOD2 pathway on regulation of metabolism gene expressions by RT-qPCR. The matrix metalloproteinases (MMP) activity was determined by gelatin zymography. The inhibitor of NF-κB and ROS scavenger were exploited to analyze the mechanism of NOD2 up-regulation in chondrocytes treated with T-2 toxin. RESULTS In chondrocytes treated with T-2 toxin, anabolism genes were down-regulated whereas catabolism genes were up-regulated, and NOD2 was identified as a significantly up-regulated gene. Intervening NOD2 expression via RNAi could ameliorate the down-regulation of anabolism genes, while inhibit the up-regulation of catablolism genes induced by T-2 toxin in chondrocytes. RNAi of RIPK2 and TBK1 in chondrocytes could obtain the similar outcome. Furthermore, up-regulation of NOD2 expression induced by T-2 toxin could be abrogated by pretreating the cells with inhibitors of NF-κB and scavenger of ROS. CONCLUSION T-2 toxin could up-regulate NOD2 expression via ROS/NF-κB pathway and activate NOD2 signaling pathway. The up-regulated NOD2 would affect the metabolism gene expressions and MMP activity in chondrocytes via RIPK2 and TBK1. The findings add new insights into understanding NOD2 effects on chondrocytes treated with T-2 toxin.

Abstract
The excessive production of inflammatory cytokines during invasive infection primarily mediates the pathophysiology of sepsis. To improve the survival of septic patients, many selective or mediator-specific anti-inflammatory agents have been developed. Saikosaponin A (SsA), a triterpenoid saponin isolated from Radix Bupleuri, inhibits the production of proinflammatory mediators in several cell types and protects against CCl4-induced liver injury in rats. However, whether SsA treatment provides protective effects against sepsis remains unknown. The aim of the present study was to investigate the anti-inflammatory role of SsA in septic rats and the possible involvement of the nucleotide-binding oligomerization domain 2 (NOD2)/NF-κB signaling pathway in the regulation of inflammatory cytokine expression. Sixty male Wistar rats were randomly divided into six groups (10 rats per group): Sham surgery, cecal ligation and puncture (CLP), CLP plus SsA (1.0 mg/kg), CLP plus SsA (2.5 mg/kg), CLP plus SsA (5.0 mg/kg) and sham surgery plus SsA (2.5 mg/kg) groups. Rats in the SsA groups were intraperitoneally (i.p.) injected with different doses of SsA following the CLP surgery. Tissues from the ileum were harvested 8 h after CLP or sham surgery and the levels of inflammatory cytokines and NOD2 mRNA, and the activation of NF-κB were measured. The concentrations of the cytokines tumor necrosis factor (TNF)-α and interleukin (IL)-6, as well as the NOD2 mRNA expression levels and NF-κB activation in the intestinal tissues were significantly increased in the septic rats of the CLP group compared with those in the sham group. SsA administration effectively suppressed the increase in the levels of TNF-α and IL-6. Moreover, the upregulation of NOD2 mRNA expression and phospho-NF-κB p65 levels was significantly inhibited following the administration of SsA. SsA may exert a protective role in the septic process by suppressing TNF-α and IL-6 concentrations in the intestines of septic rats and these effects appear to be mediated, at least partly, via inhibition of the NOD2/NF-κB signaling pathway.

Abstract
A cytosolic receptor complex called inflammasome is responsible for mounting inflammatory response by releasing pro-inflammatory cytokines, interleukin (IL)-1β and IL-18. However, inflammatory cascades mediated by the inflammasome are unknown in a lower vertebrate like fish. Therefore, in an in vitro experiment, in order to obtain a preliminary information, we conducted transcriptomic analysis of 18 cytokines including pro-inflammatory cytokines in the Japanese pufferfish (Takifugu rubripes) head kidney (HK) cells stimulated with an inflammasome-inducing agent, nigericin, and a combination of nigericin and LPS by a multiplex RT-PCR assay (GenomeLab Genetic Analysis System, GeXPS; Beckman Coulter Inc.). Furthermore, expression of IL-1β, IL-6, IL-18, nuclear factor (NF)-κB, nucleotide-binding oligomerization domain 2 (NOD2) and NOD-like receptor X1 (NLRX1) genes was examined in HK cells by a quantitative real-time PCR. Additionally, to confirm functionality of activated inflammatory immunity, we also assessed phagocytic activity, superoxide anion production (NBT assay) and lysozyme activity in the nigericin-stimulated HK cells. An increased gene expression of pro-inflammatory cytokines (IL-1β and IL-18), NF-κB and NOD2 was recorded in nigericin and combined nigericin+LPS- stimulated HK cells. Enhanced cellular (phagocytic activity and NBT assay) and humoral (lysozyme activity) immune parameters in the stimulated cells confirmed induction of inflammatory response. Results suggested probable activation of inflammasome components for processing of the inflammatory cytokines in the Japanese pufferfish.

Abstract
The novel nucleotide oligomerization domain (NOD)-like receptor (NLR) with a caspase activation and recruitment domain (CARD) 3 (NLRC3) protein belongs to the NLR family of cytosolic pathogen recognition receptors. NLRC3 has the characteristic NOD and leucine-rich repeat configuration with a less well defined CARD. T lymphocytes are known to have high NLRC3 expression, which may be involved in suppression of T cell activation. Here, we report that NLRC3 is a cytoplasmic protein that negatively regulates pro-IL-1β maturation. Among well-known inflammasome components, NLRC3 can interact with apoptosis-associated speck-like protein containing a CARD (ASC) and caspases 1 and 5. Transient transfection of NLRC3 into stable EGFP-ASC-expressing HEK293FT cells reduces NLR family, pyrin domain-containing 3 (NLRP3)/cryopyrin-induced formation of ASC specks in a dose- and time-dependent manner. This suggests that NLRC3 can regulate ASC speck formation, caspase-1 activation and IL-1β maturation. We show for the first time that inflammasome-like complexes assemble when caspase-1 and ASC are cotransfected together with NLRC3 in HEK293FT cells. However, overexpression of NLRC3 with NLRP3/cryopyrin inflammasome components suppresses pro-caspase-1 cleavage and IL-1β processing. Our study suggests that NLRC3 negatively regulates inflammatory responses.

Abstract
BACKGROUND Crohn's disease (CD) is associated with defective sensing of pathogens in genetically susceptible individuals. Nucleotide-binding oligomerization domain containing 2 (NOD2) mutations in coding regions are strongly linked to CD pathogenesis. Our laboratory has reported that microRNAs (miRNAs) are differentially expressed in CD. However, miRNA regulation of NOD2 remains unknown. This study was designed to determine whether miRNAs regulate NOD2 expression as well as downstream nuclear factor kappaB activation and inflammatory responses in colonic epithelial HCT116 cells. METHODS NOD2 and miRNA expression in stimulated HCT116 cells were assessed by quantitative reverse transcription-polymerase chain reaction. Regulation of NOD2 expression by miRNAs was determined by luciferase reporter construct assays and transfection of specific miRNA mimics. Regulation of NOD2 signaling and immune response by miRNAs was assessed by transfection of mimics followed by muramyl dipeptide stimulation. RESULTS Muramyl dipeptide-induced increases in NOD2, interleukin-8, and CXCL3 expression were inversely associated with miRNA expression. Overexpression of miR-192, miR-495, miR-512, and miR-671 suppressed NOD2 expression, muramyl dipeptide-mediated NF-κB activation, and messenger RNA expressions of interleukin-8 and CXCL3 in HCT116 cells. A single-nucleotide polymorphism (rs3135500) located in the NOD2 3'-untranslated region significantly reduced miR-192 effects on NOD2 gene expression. CONCLUSIONS To our knowledge, this is the first report demonstrating that miRNAs regulate NOD2 and its signaling pathway. Four miRNAs downregulate NOD2 expression, suppress NF-κB activity, and inhibit interleukin-8 and CXCL3 messenger RNA expression. Treatment of CD with miRNAs may represent a potential anti-inflammatory therapeutic strategy in CD patients with and without NOD2 gene mutations.

Abstract
BACKGROUND Many studies have shown that ghrelin can down-regulate inflammatory cytokine expression via the inhibition of NF-κB activity and therefore, its administration to septic patients is considered beneficial. However, our knowledge of ghrelin's effects on the upstream activators of the NF-κB pathway, such as NOD2, is still limited. This study aimed to investigate the possible involvement of the NOD2 signaling pathway in the anti-inflammatory effects of ghrelin. METHODS Twenty-four male SD rats received cecal ligation and puncture (CLP) or sham operation, followed by infusion of saline or ghrelin. The lungs were harvested 6h after CLP or sham operation and analyzed for lung histopathology, neutrophil infiltration, inflammatory cytokines (TNF-α, and IL-6), NOD2 mRNA expression, and activation of NF-κB. Furthermore, survival was recorded for ten days in additional groups of rats. RESULTS Compared with sham group, neutrophil infiltration, TNF-α and IL-6 levels, NOD2 mRNA expression, as well as NF-κB activation in lungs from rats undergoing CLP were significantly increased. After the administration of ghrelin, all inflammatory parameters analyzed were lower than those without ghrelin following CLP. In addition, ghrelin improved survival after CLP. CONCLUSION Our results indicate that in a CLP model of sepsis, the beneficial effects that ghrelin has on inflammatory outcomes are mediated at least in part through inhibition of NOD2 expression upstream of NF-κB.

Abstract
Nucleotide-binding oligomerization domain 2 (NOD2) is involved in innate immune responses to peptidoglycan degradation products. Peptidoglycans are important mediators of organic dust-induced airway diseases in exposed agriculture workers; however, the role of NOD2 in response to complex organic dust is unknown. Monocytes/macrophages were exposed to swine facility organic dust extract (ODE), whereupon NOD2 expression was evaluated by real-time PCR and Western blot. ODE induced significant NOD2 mRNA and protein expression at 24 and 48 h, respectively, which was mediated via a NF-κB signaling pathway as opposed to a TNF-α autocrine/paracrine mechanism. Specifically, NF-κB translocation increased rapidly following ODE stimulation as demonstrated by EMSA, and inhibition of the NF-κB pathway significantly reduced ODE-induced NOD2 expression. However, there was no significant reduction in ODE-induced NOD2 gene expression when TNF-α was inhibited or absent. Next, it was determined whether NOD2 regulated ODE-induced inflammatory cytokine production. Knockdown of NOD2 expression by small interfering RNA resulted in increased CXCL8 and IL-6, but not TNF-α production in response to ODE. Similarly, primary lung macrophages from NOD2 knockout mice demonstrated increased IL-6, CXCL1, and CXCL1, but not TNF-α, expression. Lastly, a higher degree of airway inflammation occurred in the absence of NOD2 following acute (single) and repetitive (3 wk) ODE exposure in an established in vivo murine model. In summary, ODE-induced NOD2 expression is directly dependent on NF-κB signaling, and NOD2 is a negative regulator of complex, organic dust-induced inflammatory cytokine/chemokine production in mononuclear phagocytes.

Abstract
Mycobacterium tuberculosis (M.tb), which causes tuberculosis, is a host-adapted intracellular pathogen of macrophages. Intracellular pattern recognition receptors in macrophages such as nucleotide-binding oligomerization domain (NOD) proteins regulate pro-inflammatory cytokine production. NOD2-mediated signalling pathways in response to M.tb have been studied primarily in mouse models and cell lines but not in primary human macrophages. Thus we sought to determine the role of NOD2 in regulating cytokine production and growth of virulent M.tb and attenuated Mycobacterium bovis BCG (BCG) in human macrophages. We examined NOD2 expression during monocyte differentiation and observed a marked increase in NOD2 transcript and protein following 2-3 days in culture. Pre-treatment of human monocyte-derived and alveolar macrophages with the NOD2 ligand muramyl dipeptide enhanced production of TNF-α and IL-1β in response to M.tb and BCG in a RIP2-dependent fashion. The NOD2-mediated cytokine response was significantly reduced following knock-down of NOD2 expression by using small interfering RNA (siRNA) in human macrophages. Finally, NOD2 controlled the growth of both M.tb and BCG in human macrophages, whereas controlling only BCG growth in murine macrophages. Together, our results provide evidence that NOD2 is an important intracellular receptor in regulating the host response to M.tb and BCG infection in human macrophages.
