- |||||||||| Preclinical, Journal: The inflammasome NLRP3 plays a dual role on mouse corpora cavernosa relaxation. (Pubmed Central) - Nov 7, 2020
ICP/MAP and sodium nitroprusside (SNP)-induced relaxation in CC were decreased in NLRP3 mice...Conversely, it reduced eNOS activity and GCβ1 expression. NLRP3 plays a dual role in CC relaxation, with its inhibition leading to impairment of nitric oxide-mediated relaxation, while its activation by LPS + ATP causes decreased CC sensitivity to NO and endothelium-dependent relaxation.

Clinical, Review, Journal: The off-label use of anakinra in pediatric systemic autoinflammatory diseases. (Pubmed Central) - Nov 6, 2020 In order to control severe and/or relapsing disease, ANA should be considered as a valuable treatment option in children suffering from rare inflammatory diseases. However, currently available data consist of retrospective studies and short case series; thus, randomized controlled trials and larger series with long-term follow up are mandatory to better assess the efficacy and cost effectiveness of ANA in these challenging patients.

[VIRTUAL] Targeting NLRP3 Inflammasome-Induced Therapy Resistance in ALL (Poster Hall (Virtual Meeting)) - Nov 5, 2020 - Abstract #ASH2020ASH_3638; The expression of NLRP3 mRNA and that of downstream proteins caspase-1 and IL-18 in ALL culture supernatants are upregulated after leukemia cells are exposed to doxorubicin and dexamethasone at 12 and 18 hours...Conclusions : Our preliminary data indicate that chemotherapy activates the NLRP3 inflammasome and downstream signals in patients undergoing therapy for ALL. Importantly, the novel triterpenoid analog, CDDO-2P-Im blocks NLRP3 activation, suppresses ALL viability and exhibits significant single agent activity in steroid-resistant ALL.

[VIRTUAL] Macaque CRISPR/Cas9 Age-Related Clonal Hematopoiesis Model Demonstrates Expansion of TET2-Mutated Clones and Applicability for Testing Mitigation Approaches (Channel 6 (Virtual Meeting)) - Nov 5, 2020 - Abstract #ASH2020ASH_3109; To address this, we treated the animal with the fastest TET2-mutant clonal expansion (ZH63) with tocilizumab, an antibody blocking IL-6 signaling, starting 13 months after transplantation and continuing for 4 months...In summary, our CRISPR/Cas9-engineered rhesus macaque ARCH model recapitulates human ARCH and uncovers the impact of TET2 LOF on hematopoiesis and inflammation, as well as demonstrates the suppressive effect of IL-6 axis blockade in TET2-mutant clonal expansions. This robust NHP model will be further utilized for examining the pathophysiology of ARCH and testing of potential therapeutic interventions.
- |||||||||| Review, Journal: Pharmacological Inhibitors of the NLRP3 Inflammasome. (Pubmed Central) - Nov 4, 2020
Direct targeting of NLRP3 protein can be a better choice because it can prevent off target immunosuppressive effects, thus restrain tissue destruction. This paper will review the various pharmacological inhibitors of the NLRP3 inflammasome and will also discuss their mechanism of action.

In this study, our results firstly indicated that NLRP3 protein was significantly up-regulated in the typical FS children compared in fever only controls. Increased NLRP3 can mediate IL-1β secretion that is responsible for the occurrence of FS.
- |||||||||| Journal: Nlrp1b1 negatively modulates obesity-induced inflammation by promoting IL-18 production. (Pubmed Central) - Nov 2, 2020
Here we show that the Nlrp1b1 allele down regulates the adipose tissue inflammatory response attenuating glucose intolerance and insulin resistance in obese C57BL/mice. Our results indicate that the positive effects of the Nlrp1b1 inflammasome on glucose tolerance and insulin sensitivity involve IL-18-mediated effects on lipolysis, pointing out that differential expression of allelic variants of genes coding for inflammasome components might control susceptibility or resistance to develop diabetes in obese individuals.

Based on our results we propose a model of bacterial killing, unrelated to NLRP3 inflammasome activation in macrophage cells. Improving understanding of the molecular pathways driving bacterial clearance within macrophage cells will aid in the development of novel immune-targeted therapeutics in a number of diseases.

Journal: Allopurinol inhibits excess glucose-induced trophoblast IL-1b and ROS production. (Pubmed Central) - Nov 2, 2020 Additionally, through its inhibition of both IL-1β and ROS production by the trophoblast, allopurinol reduced the additional pro-inflammatory and anti-angiogenic responses to excess glucose. Thus, allopurinol may be a candidate medication to prevent placental dysfunction and adverse pregnancy outcomes, such as preeclampsia, in pregnant women with diabetes.
- |||||||||| Journal: Thrombin receptor PAR4 drives canonical NLRP3 inflammasome signaling in the heart. (Pubmed Central) - Nov 2, 2020
In conclusion, PAR4 drives caspase-1-dependent IL-1β production through the canonical NLRP3 inflammasome pathway in the diabetic heart, providing mechanistic insights into diabetes-associated cardiac thromboinflammation. The emerging PAR4-selective antagonists may provide a feasible approach to prevent cardiac inflammation in patients with diabetes.
