Entry pathways of herpes simplex virus type 1 into human keratinocytes are dynamin- and cholesterol-dependent [PDF]
Herpes simplex virus type 1 (HSV-1) can enter cells via endocytic pathways or direct fusion at the plasma membrane depending on the cell line and receptor(s).

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.

Reverse Cholesterol Transport Pathway and Cholesterol Efflux in Diabetic Retinopathy [PDF]
Cholesterol esters, synthesized from cholesterol with long-chain fatty acids, are essential components of plasma lipoproteins and cell membranes that participate in various metabolic processes in the body. Cholesterol can be excreted through the cholesterol reverse transport (RCT) pathway when excessive cholesterol is produced in the extrahepatic cells,

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.

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 ...

SR-BI inhibits ABCG1-stimulated net cholesterol efflux from cells to plasma HDL
This study compares the roles of ABCG1 and scavenger receptor class B type I (SR-BI) singly or together in promoting net cellular cholesterol efflux to plasma HDL containing active LCAT. In transfected cells, SR-BI promoted free cholesterol efflux to HDL,

Background HDL is endowed with several metabolic, vascular, and immunoinflammatory protective functions. Among them, a key property is to promote reverse cholesterol transport from cells back to the liver.

Cholesterol efflux from 3D cultured hepatic constructs.
Cholesterol efflux supported by lipoproteins is a key property of hepatocytes. To assess efflux, PHH were cultured in 3D and radiolabeled with 3H-cholesterol for 24 hours after 5 and 7 days post culture.

Cellular Cholesterol Efflux Mediated by Cyclodextrins [PDF]
In this study, we compared cholesterol efflux mediated by either high density lipoproteins (HDL3) or beta-cyclodextrins, cyclic oligosaccharides that are able to dissolve lipids in their hydrophobic core. beta-Cyclodextrin, 2-hydroxypropyl-beta-cyclodextrin, and methyl-beta-cyclodextrin at 10 mM induced the release of 50-90% of L-cell [3H]cholesterol ...
