Alzheimer’s Breakthrough: Research Targets Brain Aging Process
New research is offering a potential Alzheimer’s breakthrough by shifting the focus to the brain’s aging process. Sophia Shi, PhD, recently unveiled findings in Brain Medicine that could revolutionize the understanding and treatment of Alzheimer’s disease and related conditions.
Shi’s work centers on the glycocalyx, a layer of sugar molecules protecting blood vessels in the brain. Published in Nature, the study reveals that the glycocalyx deteriorates with age, leading to blood-brain barrier issues and inflammation, both key factors in cognitive decline.
“The glycocalyx acts like a protective shield for the brain’s blood vessels,” shi said. Restoring these sugar molecules in older mice led to “remarkable improvements” in brain function, she added. This marks the first successful reversal of age-related blood-brain barrier dysfunction through glycocalyx restoration.
Shi’s interest in pattern recognition led her to glycobiology and neuroscience at Stanford, where she worked with Nobel laureate Carolyn Bertozzi and neurobiologist Tony Wyss-Coray. Her work overcame challenges in studying complex molecules and capturing glycosylation in living brain tissue.
Her work earned her the david S. Miller Young Scientist Award at the Cerebral Vascular Biology Conference. Shi will launch her own lab at Harvard’s Rowland Institute, a rare achievement after doctoral training.
“Post-translational modifications like glycosylation have been understudied for too long,” Shi said,noting their potential to transform protein function. Her research places glycoscience at the forefront of research into neurodegeneration, challenging existing ideas about therapeutic targets for alzheimer’s disease.
What’s next
Future research will explore whether glycocalyx restoration can prevent or slow Alzheimer’s progression in humans, and how lifestyle and genetics impact glycocalyx health.
