Impairment in macroautophagy/autophagy flux and inflammasome activation are common characteristics of nonalcoholic steatohepatitis (NASH). Considering the lack of approved agents for treating NASH, drugs that can enhance autophagy and modulate inflammasome pathways may be beneficial. Here, we investigated the novel mechanism of ezetimibe, a widely prescribed drug for hypercholesterolemia, as a therapeutic option for ameliorating NASH. Human liver samples with steatosis and NASH were analyzed. For in vitro studies of autophagy and inflammasomes, primary mouse hepatocytes, human hepatoma cells, mouse embryonic fibroblasts with Ampk or Tsc2 knockout, and human or primary mouse macrophages were treated with ezetimibe and palmitate...

Toll-like receptors (TLRs) are a class of receptors of the innate immune system which detect pathogen-associated and danger-associated molecular patterns in order to initiate an inflammatory response. TLR2 and TLR4 downward signaling causes the production of proinflammatory cytokines that can induce insulin resistance and cardiovascular damage in obesity and type 2 diabetes mellitus. In diabetic nephropathy, TLR4, nucleotide-binding oligomerization domain-containing protein 2 (NOD2), and NLRP3 inflammasome are involved in the production and persistence of inflammation...

Members of the IFN-inducible PYHIN protein family, such as absent in melanoma-2 and IFN-γ-inducible protein (IFI)16, bind dsDNA and form caspase-1-activating inflammasomes that are important in immunity to cytosolic bacteria, DNA viruses, or HIV. IFI16 has also been shown to regulate transcription of type I IFNs during HSV infection. The role of other members of the PYHIN protein family in the regulation of immune responses is much less clear. In this study, we identified an immune-regulatory function for a member of the murine PYHIN protein family, p205 (also called Ifi205)...

Wu-Mei-Wan (WMW) is a Chinese herbal formula used to treat type 2 diabetes. In this study, we aimed to explore the effects and mechanisms of WMW on insulin resistance in HepG2 cells. HepG2 cells were pretreated with palmitate (0.25 mM) to impair the insulin signaling pathway. Then, they were treated with different doses of WMW-containing medicated serum and stimulated with 100 nM insulin. Results showed that palmitate could reduce the glucose consumption rate in HepG2 cells and impair insulin signaling related to phosphorylation of insulin receptor (IR) and insulin receptor substrate-1 (IRS-1), thereby regulating the downstream signaling pathways...

Plexin-B2 (PlxnB2) and its ligand, CD100 (Semaphorin 4D), are originally identified as axon-guidance molecules that function during neuronal development; however, studies also showed that CD100-Plexins participate in various immune responses. In the present study, we found that the expression of PlxnB2 on keratinocytes was specifically increased in lesional skin of psoriasis patients, but not atopic dermatitis. Levels of soluble CD100 (sCD100) and membrane CD100 (mCD100) were elevated in sera of psoriasis patients and on keratinocytes of psoriatic skin, respectively...

Systemic sclerosis (SSc) is a pro-fibrotic condition with a poorly understood aetiology. Evidence presented by Artlett et al. in this issue suggests that the microRNA miR-155 is key, with its involvement dependent on the NLRP3 inflammasome. This links epigenetic events with inflammasome signalling in SSc and opens the door to new therapeutic strategies for the treatment of SSc.

Preeclampsia is a pregnancy disorder characterized by imbalance between pro- and anti-inflammatory cytokines associated with high plasma levels of uric acid and Interleukin-1 beta (IL-1β). The inflammasome is a protein complex that mediates innate immune responses via caspase-1 activation promoting secretion of IL-1β and IL-18 in their active forms, and also release of the high-mobility group box 1 protein (HMGB1). As the placenta seems to play an important role in the pathogenesis of PE, the present study investigated the expression of genes and proteins related to the inflammasome in placentas from pregnant women with severe preeclampsia...

The novel bibenzyl compound 20C plays a neuroprotective role in vitro, but its effects in vivo have not been elucidated. In this study, we estimated the efficacy of 20C in vivo using a 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine/probenecid (MPTP/p) mouse model from behavior, dopamine and neuron, and then the possible mechanisms for these effects were further investigated. The experimental results showed that 20C improved behavioral deficits, attenuated dopamine depletion, reduced dopaminergic neuron loss, protected blood brain barrier structure, ameliorated α-synuclein dysfunction, suppressed glial activation, and regulated both NF-κB signaling and the NLRP3 inflammasome pathway...

BACKGROUND: The cytoplasmatic pattern recognition receptor, NOD2 (nucleotide-binding oligomerization domain 2), belongs to the innate immune system and is among others responsible for the recognition of single-stranded RNA. With Coxsackievirus B3 (CVB3) being a single-stranded RNA virus, and the recent evidence that the NOD2 target, NLRP3 (NOD-like receptor family, pyrin domain containing 3) is of importance in the pathogenesis of CVB3-induced myocarditis, we aimed to unravel the role of NOD2 in CVB3-induced myocarditis...

Inflammation induced by high-fat diet (HFD) is of critical importance in the development of hepatic steatosis. The role of chemerin in the progress of nonalcoholic fatty liver disease (NAFLD) remains controversial. Here, we have evaluated the effects and mechanism of chemerin on insulin sensitivity and inflammation. An inhibitor (wortmannin) and agonist (insulin-like growth factor 1 (IGF-1) of phosphatidyl inositol 3-kinase (PI3K) were applied to Kupffer cells (KCs) after treatment with a concentration gradient of chemerin in vitro...

IL-1β is produced by myeloid cells and acts as a critical mediator of host defense during infection and injury. We found that the intracellular protozoan parasite Toxoplasma gondii induced an early IL-1β response (within 4 h) in primary human peripheral blood monocytes isolated from healthy donors. This process involved upregulation of IL-1β, IL-1RN (IL-1R antagonist), and NLRP3 transcripts, de novo protein synthesis, and the release of pro- and mature IL-1β from infected primary monocytes. The released pro-IL-1β was cleavable to mature bioactive IL-1β in the extracellular space by the protease caspase-1...

BACKGROUND: The NLRP3 inflammasome is a multiprotein complex that regulates the innate immune inflammatory response by activating caspase-1 and subsequent IL-1β and IL-18. Fluoxetine has been shown to have the anti-inflammatory properties in many disease models. However, the effects and mechanisms of these effects of fluoxetine in early brain injury after subarachnoid hemorrhage (SAH) have not been defined. METHODS: The SAH model was induced by an endovascular perforation in adult male Sprague-Dawley (SD) rats weighing 300-320 g...

Complex interactions between genetic and environmental factors are widely believed to underlie the incidence and progression of Parkinson's disease (PD). Rotenone is a naturally occurring metabolic toxin employed as an insecticide and piscicide identified as a risk factor for the development of PD in agricultural workers. The Nlrp3 inflammasome is an intracellular mediator that can initiate an inflammatory cascade in response to cellular stress. Reports by others indicating that NLRP3 expression was detectable in tissues obtained from Alzheimer's disease patients and that the PD-associated protein α-synuclein could activate inflammasomes in cultured glial cells, prompted us to test the prediction that Nlrp3 was required for the development of Parkinson's-like changes resulting from rotenone exposure in mice...

The NLRP3 inflammasome, a caspase-1 activation platform plays a key role in the modulation of liver inflammation and fibrosis. Here, we tested the hypothesis that interleukin 17 (IL-17) and tumor necrosis factor (TNF) are key cytokines involved in amplifying and perpetuating the liver damage and fibrosis resulting from NLRP3 activation. To address this hypothesis gain of function Nlrp3(A350V) knock-in mice were bred onto il17a and Tnf knockout backgrounds allowing for constitutive Nlrp3 activation in myeloid derived cells in mice deficient in IL-17 or TNF...

Acute lung injury (ALI) is a condition resulting from direct or indirect lung injury associated with high mortality and morbidity. The phenotype of macrophages in lung contributes to the pathological progress of ALI. Calcitonin gene-related peptide (CGRP) is one of the most abundant neuropeptides in lung, and attenuates lipopolysaccharide (LPS)-induced ALI in rats. However, the exact effect of CGRP on the activation of macrophages remains unknown. Here we investigate the effect of CGRP on the macrophages activation and inflammation in murine macrophages in vitro...
