Saturated palmitic acid induces myocardial inflammatory injuries through direct binding to TLR4 accessory protein MD2
Abstract
The free fatty acid-mediated inflammatory activities are regulated through TLR4. Here the authors show that palmitic acid binds to MD2, initiating complex formation with TLR4, recruitment of MyD88, and subsequent activation of pro-inflammatory molecules, and that MD2 blockade protects against diet-induced cardiac dysfunction.
