We previously reported that scavenger receptor class B, type I (SR-BI) mediates uptake of lipoprotein-associated cholesteryl ester and Vitamin E by porcine brain capillary endothelial cells (pBCECs). In the present study we investigated whether SR-BI is capable of mediating phosphatidylcholine (PC) uptake by pBCECs from low- and high density lipoproteins. SR-BI-overexpressing CHO cells and pBCECs showed significantly enhanced uptake rates of PC from both lipoprotein classes. In addition, preincubation of pBCECs in the presence of both lipoprotein species resulted in a significant increase of the cellular fatty acid content, particularly linoleic and arachidonic acid. Our results suggest that uptake of lipoprotein-associated PC by the cerebrovasculature via SR-BI could generate a pool of lipids containing polyunsaturated fatty acids available for transport into deeper regions of the brain.
