Abstract
Hepatosteatosis, a hallmark of alcoholic and nonalcoholic fatty liver disease (NAFLD), is characterized by accumulation of lipid storage organelles called lipid droplets (LDs) within hepatocytes. LDs primarily function to maintain cellular metabolism and protect cells from lipotoxicity by storing excess free fatty acids and cholesterol esters during nutrient excess. Conversely, LDs serve as energy sources during periods of nutrient deprivation or tissue growth.1 During chronic or excess caloric intake when lipid availability exceeds the capacity of LDs to sequester excess free fatty acids, LDs accumulate in hepatocytes.
