Question

High-density lipoproteins (HDLs) transport cholesterol from cells to the liver, where it becomes part of bile. HDLs are ____________ lipoproteins because they are used in cell repair and growth and do not tend to accumulate in body spaces where they are not needed.

Answer 1

Answer: HDLs are antiatherogenic lipoproteins....

Explanation:

The anti-atherogenic effect of HDL occurs, above all, because of its properties to carry lipids, mainly cholesterol esters from peripheral tissues to the liver, which is known as reverse cholesterol transport(RCT). However, other protective actions of HDL, in addition to RCT, have been described in several experimental models and epidemiological studies. These actions include antioxidant protection, mediation of cholesterol efflux, inhibition of the expression of cell adhesion, leukocyte activation, regulation of blood coagulation and platelet activity.
