Inflammasome-mediated secretion of IL-1β in human monocytes through TLR2 activation; modulation by dietary fatty acids.
Many studies have shown that TLR4- and TLR2-deficient mice are protected from high-fat diet-induced inflammation and insulin resistance, suggesting that saturated fatty acids derived from the high-fat diet activate TLR-mediated proinflammatory signaling pathways and induce insulin resistance. However, evidence that palmitic acid, the major dietary saturated fatty acid, can directly activate TLR...
متن کاملDietary PUFAs attenuate NLRP3 inflammasome activation via enhancing macrophage autophagy
Dietary PUFAs reduce atherosclerosis and macrophage inflammation, but how nucleotide-binding oligomerization domain leucine-rich repeat-containing receptor protein (NLRP3) inflammasome activation and autophagy influence PUFA-mediated atheroprotection is poorly understood. We fed Ldlr-/- mice diets containing 10% (calories) palm oil (PO) and 0.2% cholesterol, supplemented with an additional 10% ...
متن کاملHemin Induces the Activation of NLRP3 Inflammasome in N9 Microglial Cells
Background: Hemin is an important sterile component that induces a neuroinflammatory response after intracerebral hemorrhage, in which NLRP3 inflammasome activation has also proved to be involved. Although microglial activation acts as a key contributor in the neuroinflammatory response, the relationship between hemin and NLRP3 in microglia remains poorly understood. Objective: To investigate w...
متن کاملMechanisims of asthma and allergic disease – 1081. Resolvin inhibits the cryopyrin/nalp3 inflammasome
Background The inflammasome is a novel protein complex that stimulates caspase-1 activation to promote the processing and secretion of IL-1b, a pro-inflammatory cytokine, which is among the most biologically important inflammatory mediators in allergic airway diseases. Among the various types of inflammasomes, Cryopyrin/NALP3 has been suggested to be involved in sensing sterile stress response,...
متن کاملDifferential modulation of Toll-like receptors by fatty acids: preferential inhibition by n-3 polyunsaturated fatty acids.
Human subjects consuming fish oil showed a significant suppression of cyclooxygenase-2 (COX-2) expression in blood monocytes when stimulated in vitro with lipopolysaccharide (LPS), an agonist for Toll-like receptor 4 (TLR4). Results with a murine monocytic cell line (RAW 264.7) stably transfected with COX-2 promoter reporter gene also demonstrated that LPS-induced COX-2 expression was preferent...
