Summary of "Cholesterol Efflux Capacity and Atherosclerosis."

To the Editor: Khera et al. (Jan. 13 issue)(1) report that cholesterol efflux from macrophages was a marginally better predictor of coronary artery disease than high-density lipoprotein (HDL) cholesterol (odds ratio, 0.75 vs. 0.85). They feel that the heterogeneity in particle size, charge, and protein composition of HDL make HDL cholesterol levels a poor surrogate for cholesterol efflux capacity and reduce the predictive value of HDL cholesterol for carotid intima-media thickness and coronary artery disease. Of all the HDL particles, HDL(2) plasma levels have shown the greatest hazard reduction for incident coronary heart disease.(2) Furthermore, macrophage cholesterol efflux positively . . .

Increased cholesterol efflux capacity in metabolic syndrome: Relation with qualitative alterations in HDL and LCAT.

Metabolic syndrome (MetS) is associated with changes in HDL levels, composition and sub-fraction profile. Whether these alterations affect HDL anti-atherogenic function, specifically measured as its c...

HDL-Apolipoprotein A-I Exchange is Independently Associated with HDL Cholesterol Efflux Capacity.

High density lipoprotein (HDL) is the primary mediator of cholesterol mobilization from the periphery to the liver via reverse cholesterol transport (RCT). A critical first step in this process is the...

Cholesterol efflux capacity in humans with psoriasis is inversely related to non-calcified burden of coronary atherosclerosis.

Cholesterol efflux capacity (CEC) was recently shown to predict future cardiovascular (CV) events. Psoriasis both increases CV risk and impairs CEC. However, whether having poor CEC is associated with...

Medical and Biotech [MESH] Definitions

Fatty acid esters of cholesterol which constitute about two-thirds of the cholesterol in the plasma. The accumulation of cholesterol esters in the arterial intima is a characteristic feature of atherosclerosis.

The most abundant protein component of HIGH DENSITY LIPOPROTEINS or HDL. This protein serves as an acceptor for CHOLESTEROL released from cells thus promoting efflux of cholesterol to HDL then to the LIVER for excretion from the body (reverse cholesterol transport). It also acts as a cofactor for LECITHIN CHOLESTEROL ACYLTRANSFERASE that forms CHOLESTEROL ESTERS on the HDL particles. Mutations of this gene APOA1 cause HDL deficiency, such as in FAMILIAL ALPHA LIPOPROTEIN DEFICIENCY DISEASE and in some patients with TANGIER DISEASE.

Cholesterol which is contained in or bound to high-density lipoproteins (HDL), including CHOLESTEROL ESTERS and free cholesterol.

Cholesterol which is contained in or bound to low density lipoproteins (LDL), including CHOLESTEROL ESTERS and free cholesterol.

A fluorescent probe with low toxicity which is a potent substrate for P-glycoprotein and the bacterial multidrug efflux transporter. It is used to assess mitochondrial bioenergetics in living cells and to measure the efflux activity of P-glycoprotein in both normal and malignant cells. (Leukemia 1997;11(7):1124-30)
