Detailed Description
Nonalcoholic fatty liver disease (NAFLD) is characterized by the accumulation and deposition of fats in the hepatocytes which affect the liver structure and function. Causes of NAFLD vary but mainly attributed to dyslipidemia and obesity. Prevalence of NAFLD has been raised over years from 25% in 2005 to over 37% in 2016 and continues to increase to become one of the most common chronic liver disease (Li J et al., 2019).
The disease progress from steatosis and inflammatory infiltration that is known as nonalcoholic steatohepatitis (NASH) to liver fibrosis, cirrhosis, and ultimately hepatocellular carcinoma. Despite these serious outcomes, no definitive known approved medication for NASH has been developed. NAFLD management is mainly dependent on diet control, physical activity, and some supportive treatments mainly to prevent the disease complications (Mundi et al., 2020).
Mast cells (MCs) are responsible releasing mediators, including preformed bioactive metabolites (histamine and tryptase,), newly synthesized cytokines [transforming growth factor beta (TGF-β), tumor necrosis factor alpha (TNF-α) (Pham et al., 2022). MCs can lead to microvesicular steatosis, ductal reaction (DR), biliary senescence, inflammation, angiogenesis, and liver fibrosis during NAFLD/NASH (Huang et al., 2022). Consequently, MC stabilizer such as ketotifen has emerged as promising approach to improve patients with NASH through its antioxidant and anti-inflammatory effects (Kim et al., 2014; Abdelzaher et al., 2020).
