**About the Editors**

**Marco Segatto** (Assistant Professor) has developed a great interest in cholesterol homeostasis since completing his master's degree, focusing his attention on the physiopathological role played by lipid homeostasis in different organs and tissues such as liver, muscle, and brain. He continued to acquire new skills and knowledge about cholesterol metabolism in the brain as a Ph.D. student, and as a Postdoctoral Fellow, broadened his experience in the field of metabolism. He is currently Assistant Professor at University of Molise, and his main research interests remain focused on the involvement of lipid metabolism in brain and muscle physiopathology.

**Valentina Pallottini** (Professor), The research activity of Professor Pallottini has been focused on changes in cholesterol metabolism under different physiological and pathological conditions. Her research has been principally carried on HMGCR (3 hydroxy 3-methylglutaryl coenzyme A reductase), the rate-limiting enzyme of cholesterol biosynthetic pathway, and on cholesterol metabolism in different physiological states. Her research on cholesterol metabolism has been principally focused on aged rat livers, models with high concentration of free radicals, and gender differences. During the last 10 years, her research has been focused on the role of cholesterol metabolism in the central nervous system and its involvement in neurodevelopmental and neurodegenerative disorders.
