Biography
Prof Najjar is best recognized for identifying a key role for hepatic insulin clearance in insulin action and fat metabolism, and how reduced insulin clearance causes insulin resistance, obesity, NAFLD, and atherosclerosis. She pioneered the finding that insulin acutely reduces fatty acid synthesis as opposed to its known chronic lipogenic action.
