Thermogenic adipocytes promote HDL turnover and reverse cholesterol transport
Brown and beige adipocytes combust nutrients for thermogenesis and through their metabolic activity decrease pro-atherogenic remnant lipoproteins in hyperlipidemic mice. However, whether the activation of thermogenic adipocytes affects the metabolism and anti-atherogenic properties of high-density lipoproteins (HDL) is unknown. Here, we report a reduction in atherosclerosis in response to pharm...
متن کاملHuman paraoxonase 1 overexpression in mice stimulates HDL cholesterol efflux and reverse cholesterol transport
This study was aimed to investigate the effect of human PON1 overexpression in mice on cholesterol efflux and reverse cholesterol transport. PON1 overexpression in PON1-Tg mice induced a significant 3-fold (p<0.0001) increase in plasma paraoxonase activity and a significant ~30% (p<0.0001) increase in the capacity of HDL to mediate cholesterol efflux from J774 macrophages compared to wild-type ...
متن کاملHigh-density lipoprotein metabolism and reverse cholesterol transport: strategies for raising HDL cholesterol
A key to effective treatment of cardiovascular disease is to understand the body's complex lipoprotein transport system. Reverse cholesterol transport (RCT) is the process of cholesterol movement from the extrahepatic tissues back to the liver. Lipoproteins containing apoA-I [highdensity lipoprotein (HDL)] are key mediators in RCT, whereas non-high-density lipoproteins (non-HDL, lipoproteins co...
متن کامل-HDL concentration in tissue fluid and stimulate reverse cholesterol transport in humans
The extent to which plasma HDL concentration regulates reverse cholesterol transport (RCT) is not known. The principal acceptors of unesterified cholesterol (UC) from cultured cells are small preb -HDL, which we have shown increase in plasma during intravenous infusion of apolipoprotein A-I/phosphatidylcholine (apoA-I/PC) discs in humans. We have now examined the effects on tissue fluid HDL and...
متن کاملPivotal role of ABCA1 in reverse cholesterol transport influencing HDL levels and susceptibility to atherosclerosis.
The identification of mutations in ABCA1 in patients with Tangier disease and familial HDL deficiency demonstrated that inadequate transport of phospholipid and cholesterol to the extracellular space results in the hypercatabolism of lipid-poor nascent HDL particles. However, the relationship between changes in ABCA1 activity and HDL levels is not clear. To address this question directly in viv...
