Personalized medicine: Smart drug clears fat from liver, blood

Scientists have developed a 'smart' drug that safely clears the liver of fat and prevents blood vessels from clogging up. Similar to a trojan horse, the drug enters the liver with a trick: It uses the pancreatic hormone glucagon as vehicle to shuttle thyroid hormone T3 the live while keeping it away from other organs, thereby improving cholesterol and lipid metabolism while avoiding typical side effects of thyroid hormone.
