Astrocytes are brain cells that help, support and protect neurons, ensuring the brain functions properly by providing energy and defending against stress. However, in diseases like Alzheimer’s, these cells change their metabolism to meet higher energy demands. While initially helpful, this shift can eventually become detrimental and speed up disease progression. Compelling data indicate that the disruption of insulin signaling and the accumulation of glycogen in astrocytes contribute to the progression of Alzheimer’s disease.
This project aims to explore whether targeting astrocyte metabolism by reducing glycogen storage or enhancing insulin signaling can slow down or reverse the progression of Alzheimer’s disease. By understanding how these brain cells change in the disease and finding ways to correct these changes, we aim to develop new treatment strategies to protect brain health in Alzheimer’s patients.
