Linking Lipid Metabolism and Immune Function: New Insights into Chronic Respiratory Diseases.

Lipids play important roles in maintaining pulmonary structure, performing physiological functions and controlling the immune status of the lung. There is increasing evidence that lipid metabolism and immune activity are closely linked and that dysfunction in lipid metabolism contributes to the development and progression of chronic respiratory diseases such as COPD and asthma. These diseases are characterized by metabolic and immune dysregulation, with lipid mediators playing a key role in both the development and resolution of inflammation. In this regard, lipid metabolic pathways are attracting increasing attention as promising targets for biomarker detection and therapeutic intervention.
