Dr. Rafael Arrojo E Drigo's lab at Vanderbilt University focuses on understanding how beta cells, which produce insulin, adapt to various stresses like aging and nutritional changes. They investigate the underlying mechanisms of beta cell function and identity during these adaptations, using advanced techniques to explore their genetic and epigenetic landscapes. This research has important implications for improving treatment strategies for type 2 diabetes and enhancing beta cell longevity.

Dr. Dale Edgerton's lab at Vanderbilt University focuses on understanding how high-fat and high-fructose diets disrupt glucose metabolism. Using a unique canine model, the lab investigates liver functions related to glucose production and processing in the context of metabolic disorders like diabetes. The goal is to identify mechanisms that can inform new strategies for treatment, especially for conditions stemming from modern dietary habits.

Bingshan Li's lab at Vanderbilt University focuses on understanding how different types of brain cells communicate and interact during the progression of Alzheimer's disease (AD). By employing advanced computational techniques and human-derived brain models, the lab aims to uncover the complex cellular mechanisms that contribute to memory loss and cognitive decline in AD patients. This research provides insights that could help in developing new therapeutic strategies for this devastating disorder.

Dr. Hassane S Mchaourab's lab focuses on understanding how certain proteins transport substances across cell membranes, particularly in relation to drug resistance in bacterial infections and cancer. By examining the structural movements of these proteins, known as transporters, the lab aims to uncover how they function and how they can be targeted to improve treatment outcomes. The research combines state-of-the-art techniques like cryo-electron microscopy and machine learning to shed light on these critical biological processes.

Dr. Julio E Ayala's lab focuses on understanding how certain drugs used for treating diabetes and obesity work at the molecular level. They investigate the interactions between glucagon-like peptide-1 receptor (GLP-1R) agonists and key regulatory pathways in the brain and pancreas. Through their research, they aim to uncover new ways to enhance the effectiveness of existing medications and potentially develop new treatments for metabolic disorders.

Dr. Roland W Stein's lab studies the differences between human and rodent islet beta cells to understand how they manage insulin secretion, particularly focusing on a key protein called MAFA. They explore how variations in gene expression and postnatal development affect insulin function and diabetes risk. By using human stem cell-derived models, the lab aims to uncover mechanisms that could lead to better treatments for diabetes and other related conditions.

David Aaron Jacobson's lab at Vanderbilt University explores the mechanisms behind insulin and glucagon secretion from pancreatic islet cells, particularly in the context of type 2 diabetes. The research focuses on how certain proteins regulate calcium levels within the cells, affecting hormone secretion and contributing to diabetes complications. By understanding these processes, the lab aims to identify new therapeutic targets to improve glucose homeostasis and reduce the health burden from diabetes.
