Nlrp3 mediated immune responses can be activated by RNA and mice lacking Nlrp3, or other inflammasome components, exhibit increased mortality and a reduced immune response after influenza virus exposure.
Nlrp3(-/-) mice exhibit increased morbidity after infection with a pathogenic influenza A virus correlating with decreased neutrophil and monocyte recruitment and reduced IL-1beta, IL-18, TNF-alpha, IL-6, KC, MIP2, and IFN-alpha production.
Nlrp3 is directly activated by certain antibiotics and plays an important role in the antibiotic-mediated secretion of Il1b. In the case of polymyxin B, Nlrp3 was also required for the neutrophil influx into the peritoneal cavity.
Nlrp3 inflammasome is essential for host defence against influenza and other RNA viruses (i.e. EMCV, VSV).
Nlrp3 recruits adaptor protein Pycard and Casp1 to form an Nlrp3 inflammasome complex in response to Varicella-Zoster Virus (VZV) infection.
Nlrp3 is a component of the inflammasome and is required for inflammation in acute pancreatitis.
Nlrp3 is necessary to illicit Il1b response specific to viable, but not heat-killed, E. coli infections.
Nlrp3 inflammasome plays a role in innate immune responses against mucosal Candida infection. Nlrp3 limits the severity of infection when present in either the hematopoietic or stromal compartments.
Nlrp3/Pycard inflammasome activation following human respiratory syncytial virus infection is dependent on the activation of Tlr2/Myd88/NF-kB and reactive oxygen species/potassium efflux. (Demonstrated in human)
MIR223 and EBV miR-BART15 regulate the NLRP3 inflammasome and IL-1beta production.
Potassium efflux is a common trigger of NLRP3 Inflammasome activation by bacterial toxins and particulate matter
Mitochondrial membrane potential is required for the association of Nlrp3 and Mfn2. Mfns2 is required for the activation of Nlrp3 inflammasomes.
3, 4-methylenedioxy-β-nitrostyrene is a potent and specific inhibitor of the NLRP3 inflammasome.
Both Nlrp3 and Nlrp1a are important regulators of Toxoplasma proliferation and that IL18 signaling is required to mediate host resistance to acute toxoplasmosis.
Group B streptococcus induces Il1b, and activates the NLRP3 inflammasome by a mechanism that requires hemolysin-mediated lysosomal leakage, which enhances the interaction of bacterial RNA with NLRP3.
Activation of the Nlrp3 inflammasome is detrimental during leishmaniasis. Mice lacking the inflammasome components Nlrp3, Pycard, Casp1 exhibit defective Il1b and Il18 production at the infection site and are resistant to cutaneous Leishmania major infection.
Nlrp3 is a novel molecular target for melatonin which requires Rora to blunt the NFkB/ NLRP3 connection during sepsis.
Uropathogenic Escherichia coli protein TcpC attenuates activation of the Nlrp3 inflammasome by binding both Nlrp3 and Casp1.
Nlrp3 deficiency protects mice from the development of type 1 diabetes by suppressing Th1 responses and impairing T-cell migration to pancreatic islets through the down-regulation of chemokine expression (Ccl5, Cxcl10, Irf1) in islets.
Nlrp3 and Casp2 are required for endoplasmic reticulum stress-induced inflammation.
Impairment of the mitochondrial electron transport chain by rotenone primes Nlrp3 inflammasome activation upon costimulation with ATP.
InnateDB Annotation from Orthologs
[Homo sapiens] Influenza A virus non-structural protein 1, NS1, physically interacts with endogenous NLRP3 downregulating NLRP3 inflammasome activation as well as NF-kB, leading to a reduction in the levels of inflammatory cytokines.
[Homo sapiens] RNA cleavage products, catalyzed by RNASEL, bind to DHX33 to facilitate the formation of a complex with MAVS and NLRP3 during viral infection.
[Homo sapiens] H. pylori infection induces the expression and activation of components of NLRP3 inflammasomes in neutrophils and this activation is independent of a functional type IV secretion system, TLR2 and TLR4.
Entrez Gene
Summary This gene does not have any Entrez summary - the following is the summary from its human ortholog ENSG00000162711:
This gene encodes a pyrin-like protein containing a pyrin domain, a nucleotide-binding site (NBS) domain, and a leucine-rich repeat (LRR) motif. This protein interacts with the apoptosis-associated speck-like protein PYCARD/ASC, which contains a caspase recruitment domain, and is a member of the NALP3 inflammasome complex. This complex functions as an upstream activator of NF-kappaB signaling, and it plays a role in the regulation of inflammation, the immune response, and apoptosis. Mutations in this gene are associated with familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), chronic infantile neurological cutaneous and articular (CINCA) syndrome, and neonatal-onset multisystem inflammatory disease (NOMID). Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. Alternative 5' UTR structures are suggested by available data; however, insufficient evidence is available to determine if all of the represented 5' UTR splice patterns are biologically valid.
