The incidence of diseases characterized by a dysregulation of lipid metabolism such as
obesity, diabetes and atherosclerosis is rising at alarming rates, driving research to uncover
new therapies to manage dyslipidemias and resolve the metabolic syndrome conundrum.
Autophagy and lipid homeostasis–both ancient cellular pathways–have seemingly co-

The incidence of diseases characterized by a dysregulation of lipid metabolism such as obesity, diabetes and atherosclerosis is rising at alarming rates, driving research to uncover new therapies to manage dyslipidemias and resolve the metabolic syndrome conundrum. Autophagy and lipid homeostasis – both ancient cellular pathways – have seemingly co-evolved to share common regulatory elements, and autophagy has emerged as a prominent mechanism involved in the regulation of lipid metabolism. This review highlights recent findings on the role of autophagy in the regulation of cellular cholesterol homeostasis and lipoprotein metabolism, with special emphasis on macrophages. From modulation of inflammation to regulation of cellular cholesterol levels, a protective role for autophagy in atherosclerosis is emerging. The manipulation of autophagic activity represents a new possible therapeutic approach for the treatment complex metabolic disorders such as obesity and the metabolic syndrome.
