  • ||||||||||  pramipexole IR / Generic mfg.
    Preclinical, Journal:  Pramipexole inhibits astrocytic NLRP3 inflammasome activation via Drd3-dependent autophagy in a mouse model of Parkinson's disease. (Pubmed Central) -  Jul 30, 2022   
    Moreover, we demonstrated that both pretreatment of astrocytes with autophagy inhibitor chloroquine (40 μM) in vitro and astrocyte-specific Atg5 knockdown in vivo blocked PPX-caused inhibition on NLRP3 inflammasome and protection against DA neuron damage. Altogether, this study demonstrates an anti-neuroinflammatory activity of PPX via a Drd3-dependent enhancement of autophagy activity in astrocytes, and reveals a new mechanism for the beneficial effect of PPX in PD therapy.
  • ||||||||||  Journal:  Targeting Pancreatic Islet NLRP3 Improves Islet Graft Revascularization. (Pubmed Central) -  Jul 30, 2022   
    Transplantation of Nlrp3-/- islets or WT islets exposed to CY-09 under the kidney capsule of diabetic mice markedly improved the restoration of normoglycemia. These findings indicate that the inhibition of NLRP3 in isolated islets represents a promising therapeutic strategy to improve engraftment and function of the islets.

    Further, adding an NLR family pyrin domain containing 3 (NLRP3) inhibitors found that suppression expression of NLRP3 results in the essential proteins of pyroptosis and antioxidant evidently reduced, and adding GSDMD inhibitor found that suppression expression of GSDMD accompanies with the level of Nrf2 and heme oxygenase-1 (HO-1) obviously reduced. In summary, these findings provide a new understanding of the underlying mechanisms of the cold stress response, which can inform the development of new strategies to combat the effects of hypothermia.
  • ||||||||||  Journal:  Dehydroisohispanolone as a Promising NLRP3 Inhibitor Agent: Bioevaluation and Molecular Docking. (Pubmed Central) -  Jul 29, 2022   
    Covalent molecular docking analysis revealed that DIH fits well into the ATP-binding site of NLRP3 protein, forming a covalent bond with Cys415. In conclusion, our experiments show that DIH is an effective NLRP3 inflammasome inhibitor and provide new evidence for its application in the therapy of inflammation-related diseases.
  • ||||||||||  Review, Journal, Cytokine storm:  NLRP3 inflammasome activation and SARS-CoV-2-mediated hyperinflammation, cytokine storm and neurological syndromes. (Pubmed Central) -  Jul 29, 2022   
    In this review, we elaborate on the inflammatory responses associated with the NLRP3 inflammasome activation in COVID-19 pathogenesis, the mechanisms for the NLRP3 inflammasome activation and pathway involved, cytokine storm, and neurological complications as long-term consequences of SARS-CoV-2 infection. Also discussed is the therapeutic potential of NLRP3 inflammasome inhibitors for the treatment of COVID-19.
  • ||||||||||  Journal:  Chalcone Derivatives From Abelmoschus manihot Seeds Restrain NLRP3 Inflammasome Assembly by Inhibiting ASC Oligomerization. (Pubmed Central) -  Jul 27, 2022   
    A preliminary mechanism of action study indicated that compound 1 blocked the formation of nucleotide oligomerization domain-like receptor protein-3 (NLRP3) inflammasome formation by suppressing apoptosis-associated speck-like protein oligomerization, thereby attenuating caspase-1 activation and IL-1β release. These results reveal that compound 1 is not only a potent and efficacious NLRP3 inflammasome inhibitor but also a promising drug for the treatment of NLRP3-related diseases.
  • ||||||||||  Journal:  Polystyrene nanoparticle exposure supports ROS-NLRP3 axis-dependent DNA-NET to promote liver inflammation. (Pubmed Central) -  Jul 23, 2022   
    In turn, exposure of mice to deoxyribonuclease I (DNase Ⅰ)-coated PSNPs disassembled NET in vivo, neutrophil infiltration in the liver was reduced, the ROS-NLRP3 axis was inhibited, and the expression of cytokines was markedly decreased. Collectively, our work reveals a mechanism of NET formation in PSNP exposure-induced liver inflammation and highlights the possible role of DNase Ⅰ as a key enzyme in degrading NET and alleviating liver inflammation.
  • ||||||||||  Review, Journal:  Pathological Mechanism and Targeted Drugs of COPD. (Pubmed Central) -  Jul 23, 2022   
    NLRP3 is an important factor in the migratory aggregation of macrophages and neutrophils and the generation of oxidative stress. Inhibition of NLRP3 inflammasome indirectly blocks the inflammatory effects of IL-1β and IL-18, which may be regarded as an ideal target for COPD treatment.
  • ||||||||||  minocycline / Generic mfg.
    Journal:  Acrylamide inhibits long-term potentiation and learning involving microglia and pro-inflammatory signaling. (Pubmed Central) -  Jul 23, 2022   
    Inhibitors of toll-like receptor 4 (TLR4), and minocycline, an inhibitor of microglial activation, overcame the effects of acrylamide on LTP induction...This learning deficit was overcome by MCC950. These results indicate that cognitive impairment by acrylamide is mediated by mechanisms involving microglia and release of cytokines via NLRP3 activation.

    Review, Journal:  Targeting the NLRP3 inflammasome in cardiovascular diseases. (Pubmed Central) -  Jul 23, 2022   
    Furthermore, the non-selective NLRP3 inhibitor colchicine has been recently shown to significantly reduce cardiovascular events in patients with chronic coronary disease. In this review, we will outline the mechanisms driving NLRP3 assembly and activation, and discuss the pathogenetic role of the NLRP3 inflammasome in CVDs, providing an overview of the current and future therapeutic approaches targeting the NLRP3 inflammasome.
  • ||||||||||  Journal:  NLRP3 is its own gatekeeper: a group hug of NLRP3 monomers controls inflammation. (Pubmed Central) -  Jul 23, 2022   
    describes the cryo-electron microscopy (cryoEM) structure of an autoinhibited nucleotide-binding domain-, leucine-rich repeat (LRR)- and pyrin domain-containing protein 3 (NLRP3) decamer that assembles via LRR interactions and is further stabilized by the small-molecule NLRP3-specific inhibitor CRID3 binding into a cleft within the NACHT domain. The study provides a springboard for the development of novel NLRP3-based therapies.
  • ||||||||||  Review, Journal:  NLRP3 and pyroptosis blockers for treating inflammatory diseases. (Pubmed Central) -  Jul 23, 2022   
    Major recent developments in this area include the elucidation of mechanisms of action (MoAs) by which small molecules block NLRP3 inflammasome assembly and gasdermin D (GSDMD)-induced pyroptosis. We also discuss the status of clinical trials using agents that block specific components of the NLRP3 pathway, including their potential clinical applications for the treatment of many diseases.
  • ||||||||||  Review, Journal:  Diabetes Mellitus Promotes the Development of Atherosclerosis: The Role of NLRP3. (Pubmed Central) -  Jul 20, 2022   
    NLRP3 plays an important role in both diabetes and atherosclerosis. While the diversity of its activation modes is one of the underlying causes of complex effects in the progression of diabetes and atherosclerosis, it also provides many new insights for targeted interventions in metabolic diseases.
  • ||||||||||  Journal:  miR-25-3p ameliorates SAE by targeting the TLR4/NLRP3 axis. (Pubmed Central) -  Jul 20, 2022   
    The anti-inflammatory effect of miR-25-3p in LPS-induced CHME5 was reversed by TLR4 overexpression. miR-25-3p overexpression attenuated the activation of microglia in SAE by inhibiting the NLRP3/IL-1β/IL-18 axis by directly targeting TLR4, suggesting that miR-25-3p may be a potential target for SAE diagnosis and treatment.

    Chemotherapy-induced Peripheral Neuropathy: Pathophysiology and Mechanism-based Treatment (717 A/B) -  Jul 19, 2022 - Abstract #IASP2022IASP_357;    
    Chronic treatment of Drosophila larvae with paclitaxel caused altered branching and degeneration of nociceptive neurons, reduced thermal nociceptive responses, and activated resident macrophage-like cells, suggesting a conserved neuron-immune interaction contributing to the CIPN pathology Live imaging and superresolution approaches show alterations in endosome-mediated trafficking of integrins, and nociceptive neuron-specific overexpression of integrins conferred a protective effect. This workshop will discuss the interplay between chemotherapy-induced peripheral neuropathy and pain (CIPN) and inflammation using innovative conceptual and methodological approaches.
  • ||||||||||  Journal:  NLRP3 inflammasome triggers interleukin-37 release from human monocytes. (Pubmed Central) -  Jul 15, 2022   
    Mutagenesis of the suggested caspase-1 cleavage site (D20) or the proposed alternative cleavage site (V46) did not completely block IL-37 processing. Therefore, we propose a novel pathway in which IL-37 is cleaved by caspase-1-independent mechanisms and released following canonical and alternative NLRP3 inflammasome triggers by differential pathways.
