Congenital Hepatic Fibrosis (CHF), a genetic disease caused by mutations in the PKHD1 gene, encoding for the protein fibrocystin (FPC), is characterized by biliary dysgenesis, progressive portal fibrosis, and by a PKA-mediated activating phosphorylation of β-Catenin at Ser675. Biliary structures of Pkhd1(del4/del4) mice, a mouse model of CHF, secrete CXCL10 a chemokine able to recruit macrophages. The aim of this study is to clarify whether CXCL10 plays a pathogenetic role in disease progression in CHF/CD and to understand the mechanisms leading to increased CXCL10 secretion...

Flavones represent a class of polyphenols that are found in many plant-derived food sources. Herein, we provide evidence that the anti-inflammatory and antiproliferative effect of the flavone apigenin relies on the regulation of the gut microbiota by the NOD-like receptor family pyrin domain containing 6 (Nlrp6). When challenged by dextran sulfate sodium (DSS) in drinking water, mice were protected against colitis upon cohousing with apigenin-treated animals. In contrast, the protective effect was lost in the absence of Nlrp6...

Inflammation is central to the development of chronic obstructive pulmonary disease (COPD), a pulmonary disorder characterized by chronic bronchitis, chronic airway obstruction, emphysema, associated to progressive and irreversible decline of lung function. Emerging genetic and pharmacological evidence suggests that IL-1-like cytokines are highly detected in the sputum and broncho-alveolar lavage (BAL) of COPD patients, implying the involvement of the multiprotein complex inflammasome. So far, scientific evidence has focused on nucleotide-binding oligomerization domain-like receptors protein 3 (NLRP3) inflammasome, a specialized inflammatory signaling platform that governs the maturation and secretion of IL-1-like cytokines through the regulation of caspase-1-dependent proteolytic processing...

BACKGROUND: Recently, neoadjuvant chemotherapy with docetaxel/cisplatin/5-fluorouracil (NAC-DCF) was identified as a novel strong regimen with a high rate of pathological complete response (pCR) in advanced esophageal cancer in Japan. Predicting pCR will contribute to the therapeutic strategy and the prevention of surgical invasion. However, a predictor of pCR after NAC-DCF has not yet been developed. The aim of this study was to identify a novel predictor of pCR in locally advanced esophageal cancer treated with NAC-DCF...

BACKGROUND/AIM: Plasma trimethylamine-N-oxide (TMAO), a product of intestinal microbial metabolism of dietary phosphatidylcholine has been recently associated with atherosclerosis and increased risk of cardiovascular diseases (CVD) in rodents and humans. However, the molecular mechanisms of how TMAO induces atherosclerosis and CVD progression are still unclear. The present study tested whether TMAO induces NLRP3 inflammasome formation and activation and thereby contributes to endothelial injury initiating atherogenesis...

The NLRP3 inflammasome is a critical component of the innate immune system and can be activated in response to microbial and endogenous danger signals. Activation of the NLRP3 inflammasome results in caspase-1-dependent secretion of the proinflammatory cytokines IL-1β and IL-18. Gain-of-function missense mutations in NLRP3 result in a group of autoinflammatory diseases collectively known as the cryopyrin-associated periodic syndromes (CAPS). CAPS patients have traditionally been successfully treated with therapeutics targeting the IL-1 pathway; however, there are a number of identified CAPS patients who show only a partial response to IL-1 blockade...

The NLRP3 inflammasome is a protein complex responsible for caspase-1-dependent maturation of the proinflammatory cytokines IL-1β and IL-18. Gain-of-function missense mutations in NLRP3 cause the disease spectrum known as the cryopyrin-associated periodic syndromes (CAPS). In this study, we generated Nlrp3-knockin mice on various KO backgrounds including Il1b/Il18-, caspase-1-, caspase-11- (Casp1/11-), and Tnf-deficient strains. The Nlrp3L351P Il1b-/- Il18-/- mutant mice survived and grew normally until adulthood and, at 6 months of age, exhibited marked splenomegaly and leukophilia...

Chlorogenic acid (CGA), a kind of polyphenol found in coffee, fruits and vegetables, has potent anti-oxidant and anti-inflammatory properties. Our previous studies showed CGA could efficiently alleviate liver fibrosis in rats. However, whether CGA regulates nuclear factor erythroid-2-related factor 2 (Nrf2) anti-oxidant pathway and NLRP3 inflammasome activation and protects against carbon tetrachloride (CCl4)-induced acute liver injury are unknown. We found that CGA could increase Nrf2 activation and expression of Nrf2-related anti-oxidant genes, including HO-1, NQO1 and GCLC...

The inflammasome is a complex of proteins that through the activity of caspase-1 and the downstream substrates gasdermin D, IL-1β, and IL-18 execute an inflammatory form of cell death termed pyroptosis. Activation of this complex often involves the adaptor protein ASC and upstream sensors including NLRP1, NLRP3, NLRC4, AIM2, and pyrin, which are activated by different stimuli including infectious agents and changes in cell homeostasis. Here we discuss new regulatory mechanisms that have been identified for the canonical inflammasomes, the most recently identified NLRP9b inflammasome, and the new gasdermin family of proteins that mediate pyroptosis and other forms of regulated cell death...

Chronic obstructive pulmonary disease (COPD) is considered the fourth-leading causes of death worldwide; COPD is caused by inhalation of noxious indoor and outdoor particles, especially cigarette smoke that represents the first risk factor for this respiratory disorder. To mimic the effects of particulate matter on COPD, we isolated peripheral blood mononuclear cells (PBMCs) and treated them with combustion-generated ultrafine particles (UFPs) obtained from two different fuel mixtures, namely, pure ethylene and a mixture of ethylene and dimethylfuran (the latter mimicking the combustion of biofuels)...

Many proteins contain tandemly repeated modules of several amino acids, which act as the building blocks that form the underlying architecture of a specific protein-binding interface. Among these motifs and one of the most frequently observed is ankyrin repeats (ANK), which consist of 33 amino acid residues that are highly conserved. ANK domains span a wide range of functions, including protein-protein interactions, such as the recruitment of substrate to the catalytic domain of an enzyme, or the assembly of stable multiprotein complexes...

Pattern recognition receptors such as nucleotide-binding oligomerization domain (NOD)-containing protein receptors (NLRs) and the pyrin and hematopoitic interferon-inducible nuclear protein (HIN) domain (PYHIN) receptors initiate the inflammatory response following cell stress or pathogenic challenge. When activated, some of these receptors oligomerize to form the structural backbone of a signalling platform known as an inflammasome. Inflammasomes promote the activation of caspase-1 and the maturation of the proinflammatory cytokines, interleukin (IL)-1β and IL-18...

Caspase-4 physically interacts with caspase-1 and is believed to be a proinflammatory caspase that can induce the inflammatory form of programmed cell death (pyroptosis) and the release of mature interleukin (IL)-1β. However, the function of caspase-4 in dengue virus infection is not yet fully understood. We examined the function of caspase-4 in IL-1β production and pyroptosis during dengue virus serotype-2 (DENV-2) infection in human macrophages. In this study, DENV-2 infection increased IL-1β protein level with activated caspase-4 activity...

The nucleotide-binding and oligomerization domain-like receptor containing a pyrin domain 3 (NLRP3) inflammasome is a multiprotein complex with a role in innate immune responses. NLRP3 inflammasome dysfunction is a common feature of chronic inflammatory diseases. Microglia activation is also associated with neuroinflammatory pathologies. We previously reported that 3-(naphthalen-2-yl(propoxy)methyl)azetidine hydrochloride (KHG26792) reduced hypoxia-induced toxicity by modulating inflammation. However, no studies have elucidated the precise mechanisms for the anti-inflammatory action of KHG26792, in particular via inflammasome mediation...

Cryopyrin-associated periodic syndromes (CAPS) are linked to one single gene mutations, however they are associated with 3 syndromes, which are, from the mildest to the most severe phenotype familial cold urticaria, Muckle-Wells syndrome and chronic, infantile, neurologic, cutaneous, articular (CINCA) syndrome also called neonatal-onset multisystem inflammatory disease (NOMID). Autosomic dominant inheritance is present in most cases but in CINCA/NOMID syndrome where neomutations are more common. Mutations in the gene encoding cryopyrin, NLRP3, are associated with deregulation of caspase-1 activity, excessive interleukin-1 production and an autoinflammatory syndrome, which in familial cold urticaria and Muckle-Wells syndrome may be triggered or worsened by exposure to coldness...

AIMS: Oxidative stress and inflammation have been implicated in the pathogenesis of vascular dementia (VD). Thioredoxin-interacting protein (TXNIP) plays a vital role in oxidative stress and NOD-like receptor protein 3 (NLRP3) inflammasome activation. There is evidence that acupuncture has an antioxidative and neuroprotective effect in VD. In this study, we investigated whether acupuncture can attenuate cognitive impairment via inhibiting TXNIP-associated oxidative stress and inflammation in VD rats...

Recent studies have shown that neuroinflammation plays an important role in Alzheimer's disease (AD). Microglial cells are responsible for the phagocytosis of Amyloid-β (Aβ). However, it has been demonstrated that in AD patients the efficiency of phagocytosis decreases due to proinflammatory cytokines, such as Interleukin-1β (IL-1β), which is produced through the activation of NLRP3 inflammasome. In this study, we aimed at deciphering the mechanism underlying the NLRP3 activation. The results showed that Aβ induces an increase in the level of reactive oxygen species (ROS)...
