Actual (reported)The structural and functional alterations of high density lipoproteins (HDL) levels in type 2 diabetes (T2D) patients linked to hypertriglyceridemia, hyperglycemia, insulin resistance, inflammation and oxidation, play a major role in the increased macrovascular risk in these patients. An impaired function of the adipose tissue (AT) in T2D contributes to low HDL concentrations. Objectives: 1) Quantitative and qualitative characterisation of HDL subclasses by ultracentrifugation, proteomic and metabolomic techniques. 2) To study the relationship between the HDL subclasses, preβ1 HDL and remnant HDL, and clinical determinants of arteriosclerosis. 3) Functional in vitro studies of the HDL subclasses determined in Objective 1. 4) To study the role of AT determining the low HDL levels. 5) To study the impact of HDL increasing drugs on HDL qualitative changes.
