Central Insulin Dysregulation and Energy Dyshomeostasis in Two Mouse Models of Alzheimer’s Disease


Alzheimer’s disease (AD) is the most prevalent neurodegenerative disorder worldwide. While the causes of AD are not known, several risk factors have been identified. Among these, type 2 diabetes (T2D), a chronic metabolic disease, is one of the most prevalent risk factors for AD. Insulin resistance, which is associated with T2D, is defined as diminished or absent insulin signaling, and is reflected by peripheral blood hyperglycemia and impaired glucose clearance. In this study, we used complimentary approaches to probe for peripheral insulin resistance, central nervous system (CNS) insulin sensitivity and energy homeostasis in Tg2576 and 3xTg-AD mice, two widely used animal models of AD.📍
