  • ||||||||||  [VIRTUAL] The Contribution of the NLRP3 Inflammasome to Trauma Response in an Animal Model of PTSD () -  Sep 30, 2020 - Abstract #ACNP2020ACNP_25;    
    Additional experiments need to be conducted using model to inquire further implications regarding sex-dependent effects of the NLRP3 inflammasome in PTSD risk. As current FDA-approved treatments are shown to have a limited efficacy in individuals diagnosed with PTSD, developing an in-depth understanding of the role of these inflammatory signaling pathways in PTSD pathophysiology may be useful for developing novel pharmacological treatments.
  • ||||||||||  Journal:  NLRP3 inflammasome activity is required for wound healing after burns. (Pubmed Central) -  Sep 27, 2020   
    We show that NLRP3 is protective in burn wound healing, primarily through production of inflammatory mediators, macrophage recruitment, and polarization to a proinflammatory phenotype. Our findings highlight a central role of NLRP3 in wound healing through regulation of inflammation and macrophage polarization after burns.
  • ||||||||||  Clinical, Review, Journal:  Inflammasome-Mediated Immunogenicity of Clinical and Experimental Vaccine Adjuvants. (Pubmed Central) -  Sep 27, 2020   
    In this context, we focus on clinically relevant adjuvants that have been shown to activate the NLRP3 inflammasome and also present various experimental adjuvants that activate the NLRP3-, NLRC4-, AIM2-, pyrin-, or non-canonical inflammasomes and could have the potential to improve future vaccines. Together, we provide a comprehensive overview on vaccine adjuvants that are known, or suggested, to promote immunogenicity through inflammasome-mediated signalling.
  • ||||||||||  Clinical, Journal:  NLRP3 Is Involved in the Maintenance of Cerebral Pericytes. (Pubmed Central) -  Sep 27, 2020   
    Thus, NLRP3 activation might be essential to maintain pericytes in the healthy brain through phosphorylating AKT. The potential adverse effects on the cerebral vascular pericytes should be considered in clinical therapies with NLRP3 inhibitors.
  • ||||||||||  Review, Journal:  The NLRP3 Inflammasome: Role and Therapeutic Potential in Pain Treatment. (Pubmed Central) -  Sep 27, 2020   
    In vitro and in vivo studies have reported the activation and upregulation of NLRP3 in painful conditions including gout and rheumatoid arthritis, while inhibition of NLRP3 function or expression can mediate analgesia. In this review, we discuss painful conditions in which NLRP3 inflammasome signaling has been pathophysiologically implicated, as well as NLRP3 inflammasome-mediated mechanisms and signaling pathways that may lead to the activation of sensory neurons.
  • ||||||||||  Review, Journal:  The NLRP3 Inflammasome and Its Role in T1DM. (Pubmed Central) -  Sep 27, 2020   
    In addition, the activation and regulatory mechanisms that enhance or attenuate NLRP3 inflammasome activation are discussed. Finally, we focus on the relationship between the NLRP3 inflammasome and T1DM, as well as its potential value for clinical use.
  • ||||||||||  Journal, IO Biomarker:  Nlrp3, Csf3, and Edn1 in Macrophage Response to Saturated Fatty Acids and Modified Low-Density Lipoprotein. (Pubmed Central) -  Sep 27, 2020   
    We demonstrated that the proinflammatory milieu with high levels of PA or mmLDL promoted macrophage activation and the expression of associated genes such as Nlrp3, Csf3, and Edn1. Although the TLR4 pathway appeared to be most relevant, additional role of other genes in this process provided insights regarding the potential targets for intervention.
  • ||||||||||  methotrexate / Generic mfg., Ilaris (canakinumab) / Novartis
    Review, Journal:  Atherothrombosis and the NLRP3 inflammasome - endogenous mechanisms of inhibition. (Pubmed Central) -  Sep 26, 2020   
    Recently, the CANTOS (Canakinumab Anti-Inflammatory Thrombosis Outcomes Study) showed the successful anti-inflammatory benefit of canakinumab, a monoclonal antibody targeting interleukin-1ß (IL-1ß) toward major cardiovascular events (MACE) in patients with a previous myocardial infarction (MI)...Further support has been garnered with the results of CIRT (Cardiovascular Inflammation Reduction Trial), which showed the inability of low-dose methotrexate to reduce IL-1ß, IL-6, or high-sensitivity CRP (hsCRP) in addition to MACE among patients with prior MI or multivessel coronary artery disease (CAD) but with normal hsCRP levels...Further investigation focusing on the endogenous mechanisms of inhibition of the NLRP3 inflammasome would uncover diagnostic routes from defective means in inflammatory resolution. Specifically, pro-resolving lipid mediators, autophagy, and phosphorylation/dephosphorylation mechanisms are 3 points of worthy investigation from existing evidence.
  • ||||||||||  Journal, IO Biomarker:  Immunotherapy for stone disease. (Pubmed Central) -  Sep 26, 2020   
    The promotion of M2 over M1 macrophages and inhibition of inflammation could prevent the cascade that leads to CaOx nucleation. Future therapies may target the ability of macrophages to degrade CaOx crystals to prevent stones.
  • ||||||||||  Journal:  MFG-E8 accelerates wound healing in diabetes by regulating "NLRP3 inflammasome-neutrophil extracellular traps" axis. (Pubmed Central) -  Sep 25, 2020   
    Furthermore, NET and mCRAMP (component of NETs, the murine equivalent of cathelicidin LL-37 in human)-mediated activation of NLRP3 inflammasome and production of IL-1β/IL-18 were significantly elevated in Mfge8 macrophages compared with WT macrophages, which were also significantly dampened by the administration of rmMFG-E8. Therefore, our study demonstrated that as inhibitor of the "NLRP3 inflammasome-NETs" inflammatory loop, exogenous rMFG-E8 improves angiogenesis and accelerates wound healing, highlighting possible therapeutic potential for DFUs.
  • ||||||||||  Journal:  NLRP3 activation in endothelia promotes development of diabetes-associated atherosclerosis. (Pubmed Central) -  Sep 25, 2020   
    We found that endothelia-specific NLRP3-depletion significantly attenuated AS severity in mice treated with HFD, likely through reduced apoptotic death of endothelial cells and production of ROS. Together, our data suggest that NLRP3 activation in endothelial cells promotes development of diabetes-associated AS.
  • ||||||||||  Clinical, Journal:  Activated NLRP3 inflammasome in keratinocytes promotes cutaneous T cell response in vitiligo. (Pubmed Central) -  Sep 24, 2020   
    Our study dissected tissue specific anti-inflammatory mechanisms of butyrate during AP, suggesting that modulation of colonic butyrate levels may be a potential strategy to safeguard AP. Oxidative stress-induced NLRP3 inflammasome activation in keratinocytes promotes cutaneous T cell response, which could be targeted for the treatment of vitiligo.

    Preclinical, Journal:  Kainic acid hyperphosphorylates tau via inflammasome activation in MAPT transgenic mice. (Pubmed Central) -  Sep 24, 2020   
    Our results also revealed the positive effects of IL-1β on tau phosphorylation, which was blocked by Bay11-7082. Notably, the results indicate that Bay11-7082 acts against KA-induced neuronal degeneration, tau phosphorylation, and memory defects via inflammasomes, which further highlight the protective role of Bay11-7082 in KA-induced neuronal defects.
  • ||||||||||  PLX5622 / Daiichi Sankyo
    Journal:  Microglial depletion with CSF1R inhibitor during chronic phase of experimental traumatic brain injury reduces neurodegeneration and neurological deficits. (Pubmed Central) -  Sep 24, 2020   
    PLX5622 treatment limited TBI-associated neuropathological changes at 3 months postinjury; these included a smaller cortical lesion, reduced hippocampal neuron cell death, and decreased NOX2- and NLRP3 inflammasome-associated neuroinflammation...Overall, we show that short-term elimination of microglia during the chronic phase of TBI followed by repopulation results in long-term improvements in neurological function, suppression of neuroinflammatory and oxidative stress pathways, and a reduction in persistent neurodegenerative processes. These studies are clinically relevant and support new concepts that the therapeutic window for TBI may be far longer than traditionally believed if chronic and evolving microglial-mediated neuroinflammation can be inhibited or regulated in a precise manner.
  • ||||||||||  Journal:  Metabolic competition between host and pathogen dictates inflammasome responses to fungal infection. (Pubmed Central) -  Sep 24, 2020   
    In conclusion, macrophages use their metabolic status, specifically glucose metabolism, to sense fungal metabolic activity and increased microbial loads for activating NLRP3. Therefore, a major consequence of Candida-induced glucose starvation in macrophages is activation of inflammatory responses, with implications for understanding how metabolism modulates inflammation in fungal infections.
  • ||||||||||  Review, Journal:  Multifactorial functions of the inflammasome component NLRP3 in pathogenesis of chronic kidney diseases. (Pubmed Central) -  Sep 23, 2020   
    Interestingly, therapies targeting the inflammasome effectors (e.g., IL-1 receptor antagonists and IL-1β) have been approved for therapeutic use for NLRP3-dependent diseases; however, no NLRP3 antagonists have been approved for therapeutic use until now. This review highlights the double-edged sword-like functions of NLRP3 in the regulation of renal necroinflammation and fibrosis and therefore emphasizes the urgent need for specific NLRP3 inhibitors because of the broad therapeutic potential they offer for the treatment of CKD.
  • ||||||||||  probenecid / Generic mfg.
    Journal:  Repurposing drugs targeting the P2X7 receptor to limit hyperinflammation and disease during influenza virus infection. (Pubmed Central) -  Sep 23, 2020   
    Overall, functional foods such as BM may offer potential dietary interventions that may impact sterile inflammatory diseases such as obesity and T2D. Our study demonstrates that the anti-inflammatory drugs Probenecid and AZ11645373, which have documented pharmacokinetics and safety profiles in humans, are effective at dampening hyperinflammation and severe influenza disease providing potentially new therapeutic strategies for treating severe or pathogenic IAV infections.

    Moreover, augmented levels of circulating ASC and IL-18 proteins were found in serum of RTT patients, which are likely able to amplify the inflammatory response. Taken together, our findings suggest that RTT patients exhibited a challenged inflammasome machinery at cellular and systemic level, which may contribute to the subclinical inflammatory state feedback observed in this pathology.
  • ||||||||||  Journal:  Electroacupuncture Alleviates Osteoarthritis by Suppressing NLRP3 Inflammasome Activation in Guinea Pigs. (Pubmed Central) -  Sep 23, 2020   
    Moreover, we also found that EA treatment attenuates the NLRP3 inflammasome activation and suppresses the protein expression levels of caspase-1 and IL-1β in the cartilage tissue. Our findings suggest that EA treatment attenuates OA and joint pain by suppressing NLRP3 inflammasome activation and support further investigation of the potential therapeutic tactics.
  • ||||||||||  Preclinical, Journal, IO Biomarker:  Mesenchymal Stem Cells Attenuate Diabetic Lung Fibrosis via Adjusting Sirt3-Mediated Stress Responses in Rats. (Pubmed Central) -  Sep 22, 2020   
    In addition, MSCs also regulated the expression levels of LC3, P62, BiP, Chop, and PERK, thereby enhancing autophagy and attenuating endoplasmic reticulum stress. Taken together, our results suggest that MSCs effectively attenuate diabetic lung fibrosis via adjusting Sirt3-mediated responses, including inflammation, oxidative stress, apoptosis, autophagy, and endoplasmic reticulum stress, providing a theoretical foundation for further exploration of MSC-based diabetic therapeutics.
