Non-alcoholic fatty liver disease (NAFLD) is a complex disorder characterized by the accumulation of fat in the liver in the absence of excessive alcohol consumption. It is one of the most common liver diseases worldwide, affecting approximately 25% of the global population. It is closely associated with obesity, type 2 diabetes, and metabolic syndrome. Moreover, NAFLD can progress to non-alcoholic steatohepatitis, which can cause liver cirrhosis, liver failure, and hepatocellular carcinoma. Currently, there are no approved drugs for the treatment of NAFLD. Therefore, the development of effective drugs is essential for NAFLD treatment. In this article, we discuss the experimental models and novel therapeutic targets for NAFLD. Additionally, we propose new strategies for the development of drugs for NAFLD.
