Metabolic dysfunction-associated fatty liver disease (MAFLD) is now recognized as a leading form of chronic liver disease globally and is strongly associated with metabolic abnormalities. Traditionally, the pathogenesis of MAFLD has mainly been attributed to genetic susceptibility and unhealthy lifestyles (such as high-calorie diets and sedentary behavior). However, in recent years, environmental factors, especially air pollution, have been confirmed as independent risk factors and important promoting factors for MAFLD development and further disease progression. This review summarizes current epidemiological findings on the link between air pollution exposure and MAFLD, while exploring its potential biological mechanisms involving systemic inflammation, oxidative stress, immune alteration, genetic risk, and epigenetic regulation underlying the relationship between air pollution and hepatic steatosis. It also reviews the additive interaction between air pollution and lifestyle or socioeconomic factors in MAFLD. Finally, we also discuss multilevel strategies spanning individual-, community-, national-, and global-level cooperation to address the increasing public health burden caused by air pollution. Therefore, incorporating the assessment and control of air pollution into the comprehensive strategies for MAFLD prevention and treatment has important scientific value and public health significance.

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...
