Does reduction of glycosphingolipid biosynthesis stimulate biliary lipid secretion in mice?
Pharmacological modulation of glycosphingolipid metabolism showed surprising effects on lipid homeostasis in C57BL/6J mice. Upon administration of 100 mg AMP-DNM/kg body weight/day, plasma cholesterol and triglyceride levels decreased, biliary lipid secretion doubled and also the endpoint of reverse cholesterol transport, neutral sterol excretion, doubled.
Our data suggest that vascular abnormalities, independently of blood pressure levels, may play a role in the setting of subjective memory complaints as well as of WMH in elderly hypertensive patients. Arterial thickness and stiffness as well as endothelial function should be assessed simultaneously and may represent additional targets for the prevention of subjective memory complaints and WMH.
