詳細な説明
Sphingolipids represent a major class of lipids that are structural and signaling molecules. Major bioactive sphingolipids include ceramide, dihydroceramide, sphingosine, sphingosine-1-phosphate and sphingomyelin.
Sphingoliplids are involved in development of various chronic metabolic diseases. Some ceramides species are implicated in pancreatic β-cell apoptosis and in insulin resistance in muscle, fat and liver. Some studies have shown association between inhibition of ceramide synthesis, insulin sensibility and lower hepatic steatosis. The deposition of hepatic lipids, especially triacylglycerol, defines the development of hepatic steatosis. However, sphingolipids appear to play an important role in non-alcoholic fatty liver disease (NAFLD) and in its progression. Changes in plasma shingolipids concentrations may also contribute to the pathogenesis in cardiovascular disease and atherosclerosis. Distribution of plasma sphingolipids concentrations in type 1 and type 2 diabetes has poorly been studied.
The objective of the CERADIAB study is to compare plasma sphingoliplids concentrations in type 1 and type 2 diabetic patients.

Comparison of plasma total ceramides concentration in type 2 diabetic patients versus type 1 diabetic patients.
時間枠:Samples taken in 1 single time in the morning, patients fast for 12 hours, on 1 single day
|
Three-hundred microlitres of plasma were used to quantify dihydroceramides, ceramides, sphingomyelins and sphingosine content.
The lipid subspecies were extracted and analysed by Liquid Chromatography Mass Spectrometry (LC-MS/MS), at the Lipidomic Core Facility of the University of Bourgogne (Dijon, France).
