Plasma high-density lipoprotein (HDL) levels show a strong inverse correlation with atherosclerotic vascular disease. Previous studies have demonstrated that antagonism of miR-33 in vivo increases circulating HDL and reverse cholesterol transport (RCT), thereby reducing the progression and enhancing the regression of atherosclerosis. While the efficacy of(More)
OBJECTIVE The persistence of myeloid-derived cells in the artery wall is a characteristic of advanced atherosclerotic plaques. However, the mechanisms by which these cells are retained are poorly understood. Semaphorins, a class of neuronal guidance molecules, play a critical role in vascular patterning and development, and recent studies suggest that they(More)
RATIONALE Coronary artery disease, the direct result of atherosclerosis, is the most common cause of death in Western societies. Vascular smooth muscle cell (VSMC) apoptosis occurs during the progression of atherosclerosis and in advanced lesions and promotes plaque necrosis, a common feature of high-risk/vulnerable atherosclerotic plaques. Akt1, a(More)
Lipid accumulation in macrophages has profound effects on macrophage gene expression and contributes to the development of atherosclerosis. Here, we report that angiopoietin-like protein 4 (ANGPTL4) is the most highly upregulated gene in foamy macrophages and it's absence in haematopoietic cells results in larger atherosclerotic plaques, characterized by(More)
A therosclerosis is a chronic inflammatory disease characterized by the accumulation of lipids and fibrous elements in large arteries. This complex disease involves interactions of modified lipoproteins, monocyte-derived macrophages or foam cells, T lymphocytes, endothelial cells (ECs), vascular smooth muscle cells (VSCMs), and fibro-blasts. Monocytes and(More)
During obesity, macrophage accumulation in adipose tissue propagates the chronic inflammation and insulin resistance associated with type 2 diabetes. The factors that regulate the accrual of macrophages in adipose are not well understood. Here we show that the neuroimmune guidance cue netrin-1 is highly expressed in obese, but not lean adipose tissue of(More)
