[1.4] - the level of quercetin consumption was negatively correlated with the abundance of #Sutterellaceae and #Oscillospiraceae spp. and positively correlated with the families #Fusobacteriaceae and #Enterobacteriaceae - Quercetin was also shown to inhibit #Obesity-induced hypothalamic inflammation by inhibiting microglia-mediated inflammatory responses, likely through mechanisms involving heme oxygenase induction. - quercetin, is also heavily processed by the gut microbiota. In an in vitro anaerobic fermentation model, the fecal microbiota was shown to deconjugate rutin, isoquercetin and a mixture of quercetin glucuronides through deglycosylation, ring fission and dehydroxylation reactions to produce the metabolites 3,4-dihydrophenylacetic acid and 3-hydroxyphenylacetic acid - quercetin suppressed cPLA2 phosphorylation, an activity that was shown to prevent microglia-induced neurotoxicity in differentiated SH-SY5Y neuroblast cells [1.5] - Quercetin can be extracted from various plants including Moringa oleifera, Sophora Japonica L., berries, apples, and onions. - Quercetin exhibits unique biological characteristics including antibiotic, anti-oxidative, anti-inflammatory, immunomodulatory, and anti-fibrotic effects. - quercetin scavenges reactive oxygen species (ROS) and reactive nitrogen species (RNS), inhibits lipid oxidation, and chelates iron, protecting cells against oxidative damages. - Quercetin absorption is the small intestine , about 5 to 10% of it undergoes complete absorption in the small intestine, whereas, about 90 to 95% of quercetin is absorbed in the colon. [1.6] - As with quercetin, #Myricetin absorption rate may be low because its absorption might have been influenced by the type of glycosidic linkages. [1.7] [#Diabetes Type 2] - Quercetin has also shown to abolish NLRP3 inflammasome activation in macrophages by upregulating Akt signaling, reducing insulin resistance in mice with particulate matter-induced metabolic disorder - several kinds of #Polyphenols have shown to improve mitochondrial function, namely through the activation of the key mitochondrial biogenesis’ PGC-1α, including #Ursolic acid , #Resveratrol, quercetin and #Olive #Hydroxytyrosol References Notes[ ]
