    Shannon L. Macauley, PhD is an Assistant Professor of Internal Medicine in the Section on Gerontology and Geriatric Medicine at Wake Forest University School of Medicine. She is also a member of the Sticht Center on Aging and Alzheimer’s Prevention and the Center for Diabetes, Obesity, and Metabolism. The main focus of Dr. Macauley’s work is to understand diseases of the central nervous system (CNS) and how secondary mechanisms, such altered CNS metabolism, impact neuronal health and function. Her work is focused in two main areas: 1) the interplay between Alzheimer’s disease (AD) and type-2-diabetes (T2D) and 2) the understanding and treatment of lysosomal storage diseases (LSDs). As it relates to the relationship between AD and T2D, the Macauley lab uses mouse models to understand how metabolic perturbations, either systemically or within the brain, affect the progression of AD-related pathology, such as the production, clearance, and aggregation of amyloid-beta (Aß) or tau. She uses a variety of methods, including glucose clamps, in vivo microdialysis, and neuroimaging techniques to study the acute effects of metabolic challenges on Aß dynamics within the brain’s interstitial fluid (ISF) as well as chronic studies to investigate what metabolic factors impact the progression of AD-related pathology and functional deficits. Ultimately, the goal is to leverage these findings as therapeutic targets for treating neurodegenerative disorders.
