... disease, the molecular basis of the sterile inflammatory response involved in hypertension remains unclear. Methods: We investigated the role of macrophage NLRP3 inflammasomes in engulfing and digesting microbes, a key macrophage function, and in early onset of hypertension-associated macrophage injury...

... respectively or simultaneously without or with lipopolysaccharide (LPS). Next, Caco-2 cells were treated with trichostatin A and etomoxir to identify whether SCFAs act as HDAC inhibitors or energy substances. To activate NLRP3 inflammasome and autophagy, Caco-2 cells were treated with LPS+ATP and rapamycin...

... of NLRP3 is often indirect and can be mediated through several alternative pathways. Potassium efflux, lysosomal rupture, and oxidative stress are currently the main mechanisms associated with many activators. Methods: NLRP3 inflammasomes were activated in human RPE cells by blocking proteasomes...

..., and the histopathology of liver tissues was assessed. The expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its target genes was examined using PCR. The activation of nuclear factor kappa-B (NF-κB) and the levels of inflammatory cytokines were determined. NLRP3 inflammasome and its components were...

... cells (VSMCs) is a major initiating factor for vascular remodeling. The present study was designed to determine the roles of NLRP3 inflammasome activation in Ang II-induced VSMC phenotypic transformation and vascular remodeling in hypertension. Methods: Primary VSMCs from the aorta of NLRP3 knockout...

...Wei Ding; Tingyan Liu; Xiao Bi; Zhiling Zhang Background/Aims: Growing evidence suggests mitochondrial dysfunction (MtD) and the Nlrp3 inflammasome play critical roles in chronic kidney disease (CKD) progression. We previously reported that Aldosterone (Aldo)-induced renal injury in vitro...

...Xiaohui Zhang; Liya Pan; Kelaier Yang; Yu Fu; Yue Liu; Jinyu Chi; Xin Zhang; Siting Hong; Xiao Ma; Xinhua Yin Background/Aims: Apoptosis, fibrosis and NLRP3 inflammasome activation are involved in the development of diabetic cardiomyopathy (DCM). Human recombinant relaxin-3 (H3 relaxin) is a novel...

... blotting, and the levels of interleukin-1beta (IL-1β) in culture supernatants were quantified using an ELISA kit. Results: Aβ induced microglia activation and mitochondrial dysfunction. In addition, mitochondrial dysfunction was associated with ROS accumulation and activation of the NLRP3 inflammasome...

... Reactive Oxygen Species Detection Assay Kit. Results: Macrophages isolated from diabetic wounds exhibited a pro-inflammatory phenotype, including sustained NLRP3 inflammasome activity associated with IL-1β secretion. Our data showed that high glucose inhibited autophagy, induced ROS production...

...Xuexian Tan; Xiaohe Zheng; Zena Huang; Jiaqiong Lin; Chuli Xie; Yan Lin Background: Contrast-induced acute kidney injury (CIAKI) is a common cause of hospital-acquired acute kidney injury (AKI). S100A8/A9-TLR4-NLRP3 inflammasome pathway triggers inflammation, apoptosis and tissue injury in several...

... endothelial precursor cell (EPC) function via inhibiting Nod-like receptor protein 3 (NLRP3) inflammasome in streptozotocin (STZ)-induced diabetic mice. Methods: Male C57BL/6 mice were randomly divided into three groups: control, STZ-induced diabetic mice and fenofibrate treated diabetic group. Wound closure...

... decreasing the lung wet/dry(W/D) weight ratio and mitigating pathomorphologic changes. Moreover, the oxidative stress injury, inflammatory reaction, and apoptosis in lung epithelial cells were inhibited by Dex treatment. In addition, the activation of NLRP3 inflammasome was restrained by Dex both in lung...

... recorded after the last OVA challenge. Nasal mucosa tissues and serum were collected. MiR-133b expression, serum OVA-specific immunoglobulin E (IgE) concentration, proinflammatory cytokines (TNF-α, IL-4, IL-5, IL-10 and IFN-γ) levels, and Nlrp3 inflammasome activation were measured by RT-PCR, ELISA...

...Yibo Zhuang; Fei Zhao; Jing Liang; Xu Deng; Yue Zhang; Guixia Ding; Aihua Zhang; Zhanjun Jia; Songming Huang Background/Aims: The activation of NOD-like receptor family, pyrin domain containing3 (NLRP3) inflammasome has been shown to be positively correlated with the severity of proteinuria...

... tissue. SDS treatment inhibited the activation of NLRP3 inflammasome and subsequent caspase-1 cleavage as well as interleukin (IL)-1β secretion both in vivo and in vitro . Moreover, SDS administration up-regulated SIRT1 expression. Importantly, knockdown of SIRT1 reversed the inhibitory effect of SDS...

... by multiple assays including Western blotting, enzyme-linked immunosorbent assay (ELISA) and luciferase reporter assay. Results: MiR-9 inhibited while anti-miR-9 antisense oligonucleotides induced interleukin-1 beta (IL-1β) and NLRP3 inflammasome activation in all in vitro models. Janus kinase 1 ( JAK1...

...Zena Huang; Xiaodong Zhuang; Chuli Xie; Xun Hu; Xiaobian Dong; Yue Guo; Shaofen Li; Xinxue Liao Background/Aims: This study aimed to investigate whether exogenous hydrogen sulfide (H 2 S) confered cardiac protection against high glucose (HG)-induced injury by inhibiting NLRP3 inflammasome...

... co-infiltrated with both M1MΦ and M2MΦ; IL-1β exhibited the same infiltrating tendency as M1MΦ, which was detected by immunohistochemistry. Increasing ventricular fibrosis was confirmed by Masson staining. CaSR and NLRP3 inflammasome in the MI group were upregulated in MΦ subsets in myocardium...
