“…Indeed, the molecular characterization of lipids has revealed how sphingolipids, ceramides, and lysophospholipids are among the lipid classes playing a major role in atherosclerosis formation and progression. [7][8][9] Only few papers have deeply evaluated the lipid composition of atherosclerotic plaques in humans [10,11] and if-and to which extent-dietary or pharmacological treatments can modify the plaque lipidome. How these modifications can affect atherosclerosis, is still an open question.…”

Scope Specific lipid molecules circulating in plasma at low concentrations have emerged as biomarkers of atherosclerotic risk. The aim of the present study is that of evaluating, in an athero‐prone mouse model, how different diets can affect plasma and aorta lipidome. Methods and results Thirty‐six apoE knockout mice are divided in three groups and feed 12 weeks with diets differing for cholesterol and fatty acid content. Atherosclerosis is measured at the aortic sinus and aorta. Lipids are quantified in plasma and aorta with mass spectrometry. The cholesterol content of the diets is the main driver of lipid accumulation in plasma and aorta. The fatty acid composition of the diets affects plasma levels both of essential (linoleic acid) and nonessential (myristic and arachidonic acid) ones. Lipidomics show a comparable distribution, in plasma and aorta, of the main lipid components of oxidized LDL, including cholesteryl esters and lysophosphatidylcholines. Interestingly, lactosylceramide, glucosyl/galactosylceramide, and individual ceramide species are found to accumulate in diseased aortic segments. Conclusion Both the cholesterol and fatty acid content of the diets profoundly affect plasma lipidome. Aorta lipidome is likewise affected with the accumulation of specific lipids known as markers of atherosclerosis.
