TLR9 and metabolic dysfunction-associated steatohepatitis: TLRs involved in the pathogenesis of NASH are TLR2 (for lipoproteins and glycolipids in bacteria adhering to myeloid dendritic cells mast cells or monocytes), TLR4 (for palmitic- stearic and lauric- acid, and LPS of B cells myeloid dendritic cells, mast cells, monocytes and intestinal epithelium) (20), and TLR9 (for unmethylatedCpG DNA- bacterial particles) (12) Table 1.
