Polyphenol-rich extra-virgin olive oil influences bioenergetics and may modulate NLRP3 inflammasome in PBMCs from children and adolescents with obesity https://www.diningandcooking.com/2753832/polyphenol-rich-extra-virgin-olive-oil-influences-bioenergetics-and-may-modulate-nlrp3-inflammasome-in-pbmcs-from-children-and-adolescents-with-obesity/ #biochemistry #CellBiology #ChildrenObesity #diseases #Endocrinology #ExtraVirginOliveOil #HumanitiesAndSocialSciences #Inflammasome #MedicalResearch #Mediterranean #MediterraneanOliveOil #Mitochondria #multidisciplinary #NLRP3 #Olive #OliveOil #PBMCs #physiology #polyphenols #science

Even with #antiretroviral therapy, HIV-1 can still cause persistent inflammation in macrophages. This study shows that intron-containing #HIV1 RNA (icRNA) activates NLRP1 #inflammasome & induces IL-1β secretion in myeloid cells, independent of RIG-I-like receptors @PLOSBiology https://plos.io/45VTGBR

What is the mechanistic link between the NLRP3 #inflammasome, #autophagy & inflammatory #bowel disease (IBD)? This study shows that VANGL2 reduces #IBD progression by recruiting the ubiquitin ligase MARCH8 to regulate NLRP3 activation via OPTN-mediated autophagy plosbiology https://plos.io/42FTqFO

'Here, we show that Arachidonic Acid inhibits the NLRP3 inflammasome, through a PLC-JNK-dependent mechanism, to supress IL-1β production under physiological conditions. This provides a mechanistic basis for how dietary manipulation such as fasting influences the inflammatory state and is likely to be critical for reducing the metaflammation underpinning many diseases induced by the Western Diet.'

"Inflammasome-mediated caspase-1 activation facilitates innate immune control of Plasmodium in the liver, thereby limiting the incidence and severity of clinical malaria. However, caspase-1 processing occurs incompletely in both mouse and human hepatocytes and precludes the generation of mature IL-1β or IL-18, unlike in other cells. Why this is so or how it impacts Plasmodium control in the liver has remained unknown."

`Through unbiased analyses of #RNA and protein profiles in #Inositol polyphosphate-5-phosphatase D (INPP5D) -disrupted iPSC-derived human #microglia, we find that reduction in INPP5D activity is associated with molecular profiles consistent with disrupted #autophagy and #inflammasome activation.. findings provide insights into the molecular mechanisms underlying microglia-mediated processes in #AD and highlight the inflammasome as a potential #therapeutic target`

'Gefitinib (GF), the tyrosine kinase inhibitor (TKI) targeting epidermal growth factor receptor, initiates lung #inflammation through the NLR family pyrin domain containing 3 (NLRP3) inflammasome. However, the molecular targets and mechanisms underlying the inflammatory action of GF remain unknown. In this study, we identified mitochondrial Src family kinases (mSFKs) as key determinants of GF-induced #NLRP3 #inflammasome activation.'

How the inflammasome is activated. Almost poetic seeing it in step-wise motion here...
