ANGPTL4-the Link Binding Lipid Metabolism and Inflammation.

BACKGROUND

Angiopoietin-like 4 (ANGPTL4) belongs to the family of angiopoietin- like proteins. The involvement of ANGPTL4 in various aspects of lipid metabolism and inflammation has become an important area of research.

METHODS

A thorough search on PubMed related to ANGPTL4, lipid metabolism, and inflammation was performed.

RESULTS

Over the past two decades, the recognition of ANGPTL4 as a potent regulator of lipid metabolism has substantially increased. As part of the senescence-associated secretory phenotype, ANGPTL4 also serves as an inflammatory mediator. Considering the advancements in ANGPTL4 research, we have highlighted that ANGPTL4 acts as a key node linking lipid metabolism and inflammation. ANGPTL4 impacts inflammation by regulating lipid metabolism. It affects critical enzymes (lipoprotein lipase, hepatic lipase, endothelial lipase, and acetyl-CoA carboxylase), regulatory factors (AMPK, cAMP, SLC7A11, GPX4, and mTOR), and receptors (LepR, CD36, and PPARγ) of lipid oxidation, synthesis, and peroxidation, thereby affecting immune cells and inflammatory pathways.

CONCLUSION

Understanding the potential association and the therapeutic value of ANGPTL4 for regulating lipid metabolism and inflammation could contribute to drug discovery and therapeutic development.
