Cyclosporine (CsA), which is a well-known immunosuppressive agent that inhibits calcineurin, has the additional effect of inhibiting the mitochondrial permeability transition pore (mPTP), thereby, preventing mitochondrial swelling and injury.

The liver maintains systemic lipid homeostasis by regulating lipid synthesis, catabolism, and transportation. Dysregulation of hepatic lipid metabolism precipitates disorders, such as non-alcoholic fatty liver disease (NAFLD), affecting the whole body. Thus, comprehending and studying hepatic lipid metabolism is crucial for preventing and treating metabolic liver diseases. Traditionally, researchers have investigated the impact of a single nutrient on hepatic lipid metabolism. However, real-life dietary patterns encompass diverse nutrients rather than single components. In recent years, there have been increased studies and notable progress regarding the effects of distinct dietary patterns on hepatic lipid metabolism.
