FST and atherosclerosis: Our study shows that treatment of obese patients without overt type 2 diabetes with high dose of liraglutide for a short period of time induces changes in lipoprotein and lipid profile that are associated with lower risk of atherosclerosis and CVD and reduces the blood levels of activin AB and its antagonist, i.e. follistatin, a hormone recently identified as a potentially major player in insulin sensitivity.
