The roles of different pathways in the release of cholesterol from macrophages
Cholesterol efflux occurs by different pathways, including transport mediated by specific proteins. We determined the effect of enriching cells with free cholesterol (FC) on the release of FC to human serum.

Familial HDL deficiency (FHD) is the heterozygous form of Tangier disease (TD). Mutations of the ABCA1 gene cause FHD and TD. FHD/TD cells are unable to normally efflux cholesterol onto nascent HDL particles, which are rapidly catabolized. TD fibroblasts

The mass efflux of free and esterified cholesterol was studied in skin fibroblasts loaded with cholesterol by incubation with low density lipoproteins (LDL) isolated from normal or hypercholesterolemic cynomolgus monkeys.

Inhibition of Mitogen-Activated Protein Kinase Erk1/2 Promotes Protein Degradation of ATP Binding Cassette Transporters A1 and G1 in CHO and in HuH7 cells. [PDF]
Signal transduction modulates expression and activity of cholesterol transporters. We recently demonstrated that the Ras/mitogen-activated protein kinase (MAPK) signaling cascade regulates protein stability of Scavenger Receptor BI (SR-BI) through ...

Importance of macrophage cholesterol content on the flux of cholesterol mass
Net flux of cholesterol represents the difference between efflux and influx and can result in net cell-cholesterol accumulation, net cell-cholesterol depletion, or no change in cellular cholesterol content.

A new pathway of macrophage cholesterol efflux [PDF]
Macrophage foam cells (i.e., cholesteryl ester-laden macrophages) are abundant in atherosclerotic plaques, and increased macrophage foam cell content is associated with plaque instability (1, 2). Macrophages are generally thought to unload surplus cholesterol via efflux mediated by the ATP-binding cassette transporters A1 and G1 (ABCA1 and ABCG1) to ...

Cholesterol uptake and efflux are impaired in human trophoblast cells from pregnancies with maternal supraphysiological hypercholesterolemia. [PDF]
Maternal physiological (MPH) or supraphysiological hypercholesterolaemia (MSPH) occurs during pregnancy. Cholesterol trafficking from maternal to foetal circulation requires the uptake of maternal LDL and HDL by syncytiotrophoblast and cholesterol efflux

The ability of HDL to support macrophage cholesterol efflux is an integral part of its atheroprotective action. Augmenting this ability, especially when HDL cholesterol efflux capacity from macrophages is poor, represents a promising therapeutic strategy.

Effects of dalcetrapib in patients with a recent acute coronary syndrome [PDF]
In observational analyses, higher levels of high-density lipoprotein (HDL) cholesterol have been associated with a lower risk of coronary heart disease events.

Regulation of ABCA1-mediated cholesterol efflux by sphingosine-1-phosphate signaling in macrophages
Sphingolipid and cholesterol metabolism are closely associated at the structural, biochemical, and functional levels. Although HDL-associated sphingosine-1-phosphate (S1P) contributes to several HDL functions, and S1P signaling regulates glucose and ...
