Abstract
The scavenger receptor class B type I (SR-B1) plays an important role in meditating the uptake of HDL-derived cholesterol and cholesteryl ester in the liver and steroidogenic tissues. In addition to being ubiquitous, SR-B1 is a high-density lipoprotein (HDL) receptor in many tissues, though the mechanism by which SR-B1 does this is unclear. Other than its role as an HDL receptor, SR-B1 is also involved in pathogen recognition; its expression can be modulated by lipopolysaccharide and oxidative stress; and it plays a significant role in the uptake of lipid soluble vitamins, such as vitamin E and carotenoids. In this short review, we have summarized the biological aspects to which SR-B1 has been thus far associated.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
