D FASN, contributing for the exacerbation of hepatic steatosis and inflammation in NAFLD [97]. The deleterious mechanism induced by the binding of cytotoxic bacterial metabolites to TLR-4 is shown in Figure 4.Int. J. Mol. Sci. 2021, 22, x FOR PEER Assessment Int. J. Mol. Sci. 2021, 22,8 of 23 eight ofFigure four. Molecular mechanisms by which fructose induces nonalcoholic steatohepatitis. Increased intestinal permeability Figure 4. Molecular mechanisms by which fructose induces nonalcoholic steatohepatitis. Improved intestinal permeability (“leaky gut”) and dysbiosis produced by higher fructose intake market lipopolysaccharide (LPS) translocation from the (“leaky gut”) and dysbiosis created by higher fructose intake market lipopolysaccharide (LPS) translocation in the intestine intestine for the portal blood to reach the liver. Then, LPS activates the Toll-like receptor (TLR)-4/MyD88 signaling pathway, portal blood to reach the liver. Then, LPS activates the Toll-like receptor (TLR)-4/MyD88 signaling pathway, inducing tumor necrosis factor-alpha (TNF-) through the nuclear translocation of transcriptionnuclear element kappa inducing tumor necrosis factor-alpha (TNF-) by way of the nuclear translocation of transcription nuclear kappa B (NF-B), which reinforces the inflammatory course of action by way of NLRP3 inflammasome CK2 Purity & Documentation activation plus the subsequent matB (NF-B), which reinforces the inflammatory procedure via NLRP3 inflammasome activation as well as the subsequent uration of interleukin (IL)-1 beta (),(), caspase and IL-18. In addition, TNF- and caspase 11 promotesterol-responsive maturation of interleukin (IL)-1 beta caspase 1, 1, and IL-18. Furthermore, TNF- and caspase promote sterol-responsive element-binding protein 1 c (SREBP1c) activation and nuclear element E2-related issue two (Nrf2) inhibition, when IL-6 drives element-binding protein 1 c (SREBP1c) activation and nuclear factor E2-related aspect 2 (Nrf2) inhibition, while IL-6 drives hepatic stellate cell (HSC) activation, an orchestrated interaction of a variety of molecular components, leading to oxidative pressure, hepatic stellate cell (HSC) activation, an orchestrated interaction of several molecular things, major to oxidative pressure, inflammation, steatosis, and fibrogenesis, which pave the solution to nonalcoholic steatohepatitis (NASH) development. inflammation, steatosis, and fibrogenesis, which pave the approach to nonalcoholic steatohepatitis (NASH) improvement.TLR-4 promotes NF-B signaling, and this pathway upregulates the transcription of TLR-4 promotes NF-B signaling, and this pathway upregulates the transcription of the NOD-like receptor family members pyrin domain containing three (NLRP3) inflammasome and proinNOD-like receptor family pyrin domain containing three (NLRP3) inflammasome and also the proinflammatory cytokinesas IL-1 and TNF-TNF- [96,98]. Research performed in mice flammatory ETB Synonyms cytokines such such as IL-1 and [96,98]. Research performed in mice models models have shown that fructose triggers the infiltration/activationmacrophages/Kupffer have shown that fructose triggers the infiltration/activation of of macrophages/Kupffer cells, causing enhanced levels of ROS, and induces thenecrosis of hepatocytes by means of cells, causing increased levels of ROS, and induces the necrosis of hepatocytes by means of TNF- and IL-6 upregulation (90). The elements underlying the progression from NAFLD TNF- and IL-6 upregulation (90). The things underlying the progression from NAFLD to NASH are multifactorial, but NLRP3 inflammasome activatio.
