However, P. acnes itself possibly contributes to FoxO1 down-regulation, like H. pylori infection which induces nuclear inactivation of FoxO1 in human gastric cells to slow down autophagic clearance. As bisphosphonates, which often improve SAPHO syndromes, enhance autophagy, it may be worth testing whether their combination with antibiotics is synergistic in SAPHO syndromes.

SCPE reduced serum IL-1β, IL-6, IL-18, and TNF-α levels and reduced hippocampal NLRP3, ASC, caspase-1, GSDM-D, IL-1β, IL-6, IL-18, and Aβ expression. Thus, SCPE exerts an antipyroptotic effect in aging, mainly by suppressing the NLRP3/caspase-1 signaling pathway.
- |||||||||| Journal: Neuroepithelial control of mucosal inflammation in acute cystitis. (Pubmed Central) - Nov 30, 2019
Clinical relevance was suggested by elevated urine SP levels in patients with acute cystitis, compared to patients with asymptomatic bacteriuria identifying NK1R/SP as potential therapeutic targets. We propose that NK1R and SP influence the severity of acute cystitis through a neuro-epithelial activation loop that controls pain and mucosal inflammation.
- |||||||||| Review, Journal: Phytochemicals as Novel Therapeutic Strategies for NLRP3 Inflammasome-Related Neurological, Metabolic, and Inflammatory Diseases. (Pubmed Central) - Nov 29, 2019
The present review article has been intended to provide an integrated and critical overview of the available clinical and experimental evidence about the role of NLRP3 inflammasome in the pathophysiology of neurological, psychiatric, metabolic, and inflammatory diseases, including PD, AD, MS, depression, obesity, type 2 diabetes, arthritis, and intestinal inflammation. Special attention has been paid to highlight and critically discuss current scientific evidence on the effects of phytochemicals on NLRP3 inflammasome pathways and their potential in counteracting central neuroinflammation, metabolic alterations, and immune/inflammatory responses in such diseases.

Preclinical, Journal: The inflammasome potentiates influenza/Staphylococcus aureus superinfection in mice. (Pubmed Central) - Nov 28, 2019 A neutrophil elastase inhibitor blocked ASC inflammasome-independent production of IL-1β and the IL-1 receptor antagonist, anakinra, confirmed that IL-1 remains crucial to the clearance of bacteria during superinfection...Collectively, our results demonstrate that ASC augments the clearance of bacteria, but can also contribute to inflammation and mortality. ASC should be considered as a therapeutic target to decrease morbidity and mortality during bacterial superinfection.

Journal: Taurine attenuates arsenic-induced pyroptosis and nonalcoholic steatohepatitis by inhibiting the autophagic-inflammasomal pathway. (Pubmed Central) - Nov 28, 2019 In mouse livers, we show that arsenic trioxide (AsO) induced NASH, increased autophagy and NLRP3 inflammasome activation, increased lipid accumulation, and resulted in dysregulation of lipid-related genes...These results demonstrated that AsO-induced pyroptosis involves autophagy, CTSB, and the NLRP3 inflammasome cascade, and that Tau alleviates AsO-induced liver inflammation by inhibiting the autophagic-CTSB-NLRP3 inflammasomal pathway rather than decreasing lipid accumulation. These findings give insight into the association of autophagy, inflammation, pyroptosis, and NASH induced by AsO.

Finally, we showed that acrolein induced cell toxicity and decrease of EAAT1 expression, suggesting that acrolein may induce a loss of glutamate uptake function. In conclusion, we demonstrate that acrolein induces astrocytic inflammation through NLRP3 inflammasome, which is regulated by ADAM10 and attributed to p38 MAPK-activated NF-κB p65 activity.

Furthermore, a significant increase of ovulation-related genes, hypoxia inducible factor (HIF)-1α and endothelin (ET)-1, was found after 52 h-treatment of PMSG. To our knowledge, it is the first time to clearly indicated the activation of NLRP3 inflammasome may contribute to the ovulation of PMSG-treated ovaries, which will help to further clarify the ovulatory mechanism in mammals.
- |||||||||| Journal: RIPK3-MLKL-mediated necroinflammation contributes to AKI progression to CKD. (Pubmed Central) - Nov 22, 2019
Bone marrow chimeras confirmed that RIPK3-MLKL-dependent necroptosis is responsible for the initiation of the early renal injury after IRI, and then necroptosis triggered NLRP3 inflammasome activation, which subsequently accelerates necroptosis and triggers more inflammation in an auto-amplification loop. These data indicate that necroinflammation driven by RIPK3-MLKL-dependent necroptosis plays a crucial role in the progression of IRI to CKD.

Importantly, blockade of P2X7R leads to antidepressant-like effects in different animal models, which corroborates the findings that the gene encoding for the P2X7R is located in a susceptibility locus of relevance to depression in humans. This review will discuss recent findings linked to the P2X7R involvement in stress and MDD neuropathophysiology, with special emphasis on neurochemical, neuroimmune, and neuroplastic mechanisms.
- |||||||||| Preclinical, Journal: Compromised NLRP3 and AIM2 inflammasome function in autoimmune NZB/W F1 mouse macrophages. (Pubmed Central) - Nov 21, 2019
It remains to be established whether the low inflammasome function could contribute to loss of tolerance and the onset of autoimmunity in NZB and NZB/W F1. However, with amplifying inflammatory stimuli through the course of disease, the NLRP3 response in the NZB/W F1 may be sufficient to contribute to kidney damage at later stages of disease.
- |||||||||| Journal: SARS-Coronavirus Open Reading Frame-3a drives multimodal necrotic cell death. (Pubmed Central) - Nov 21, 2019
Finally, SARS 3a activates caspase-1 either directly or via an enhanced potassium efflux, which triggers NLRP3 inflammasome assembly. In summary, Rip3-mediated oligomerization of SARS 3a causes necrotic cell death, lysosomal damage, and caspase-1 activation-all likely contributing to the clinical manifestations of SARS-CoV infection.
- |||||||||| Clinical, Journal: In situ inflammasome activation results in severe damage to the central nervous system in fatal Zika virus microcephaly cases. (Pubmed Central) - Nov 21, 2019
An immunohistochemical analysis of tissues in the neural parenchyma showed significantly higher expression of the receptors NLRP1, NLRP3, and AIM2, cytokines IL-1β, IL-18, and IL-33, and enzymes caspase 1, iNOS, and arginase 1 in ZIKV-positive microcephaly cases than in flavivirus-negative controls. These results suggest that inflammasome activation can aggravate the neuroinflammatory response and consequently increase CNS damage in neonates with fetal neural ZIKV infection and microcephaly.

Journal, IO Biomarker: Monosodium Urate Contributes to Retinal Inflammation and Progression of Diabetic Retinopathy. (Pubmed Central) - Nov 21, 2019 These results were associated with effects of the hypouricemic drugs on down-regulating diabetes-induced levels of oxidative stress markers as well as expression of components of the NLRP3 inflammasome such as NLRP3, TLR4 and IL-1β. The outcomes of these studies support a contributing role of MSU in diabetes-induced retinal inflammation and suggest that asymptomatic hyperuricemia should be considered as a risk factor for DR induction and progression.

The results shown that IL-1b caused a significant increase of Vimentin and decrease of E-cadherin, which were viewed as two important indicators of the EMT phenomenon. These data revealed that the induction of EMT was involved in the lung cancer risk of PM2.5 in vivo, and IL-1b secreted by NLRP3 inflammasome may involve in EMT to induce the invasion and migration in NSCLC, thereby putatively serving as a novel therapeutic target for PM2.5 induced lung cancer.
- |||||||||| Journal: D-Ribose Induces Podocyte NLRP3 Inflammasome Activation and Glomerular Injury via AGEs/RAGE Pathway. (Pubmed Central) - Nov 19, 2019
Mechanically, AGEs formation inhibition and cleavage or silencing of RAGE gene were shown to suppress D-ribose-induced NLRP3 inflammasome formation and activation, as shown by significant reduction of NLRP3 inflammasome molecular aggregation, caspase-1 activity and IL-1β production. These results strongly suggest that relatively long term administration of D-ribose induces NLRP3 inflammasome formation and activation in podocytes via AGEs/RAGE signaling pathway, which may be one of important triggering mechanisms leading to diabetic nephropathy.

Further, NGR1 treatment inhibited the activation of the NF-κB pathway, and the NLRP3 inflammasome in LPS stimulated RAW264.7 macrophages. The study data indicated that NGR1 might relieve atopic dermatitis via inhibiting inflammation through suppressing the NF-κB signaling pathway and NLRP3 inflammasome activation.
