Abstract
Purpose of review: Although therapies for hyperlipidemia and hypertension have been shown to be highly effective, they have not sufficiently mitigated overall cardiovascular disease risk. Endothelial cells (ECs) are an integral mediator in the development and progression of atherosclerotic cardiovascular disease. The purpose of this review is to provide an update on the current state of endothelial lipid metabolism research, with particular emphasis on atherosclerosis.
Recent findings: Although it has been known that elevated palmitic acid (PA) levels were linked to metabolic dysfunction, inflammation and cardiovascular diseases, more recent studies presented here elucidate the mechanisms behind the negative effects induced by PA. Palmitoylation was found to be detrimental in the case of pyruvate kinase isozyme M2 (PKM2) activity, but also vital for the normal functioning of endothelial ciliation and cell health. Endothelial cholesterol metabolism and hemodynamic forces have also been further confirmed to be key regulators in vessel development and endothelial homeostasis. Perturbations in these pathways promote endothelial dysfunction and maladaptive lipid accumulation.
Summary: Although atherosclerosis remains a complex, multifactorial disease that arises from the coordinated dysfunction across multiple vascular and immune cell types, substantial advances have been made in identifying mechanisms behind dysfunctional endothelial lipid metabolism. Despite this, further investigation is necessary to identify high impart therapeutic targets aimed at reducing overall cardiovascular disease risk.
期刊介绍：
With its easy-to-digest reviews on important advances in world literature, Current Opinion in Lipidology offers expert evaluation on a wide range of topics from six key disciplines including nutrition and metabolism, genetics and molecular biology, and hyperlipidaemia and cardiovascular disease. Published bimonthly, each issue covers in detail the most pertinent advances in these fields from the previous year. This is supplemented by a section of Bimonthly Updates, which deliver an insight into new developments at the cutting edge of the disciplines covered in the journal.
