Mount Sinai researchers have discovered a potential new method to treat Alzheimer’s by targeting the plexin-B1 protein to improve plaque clearance in the brain, opening avenues for future therapeutic strategies. Credit: SciTechDaily.com Researchers at the Icahn School of Medicine at Mount Sinai have achieved a major breakthrough in Alzheimer’s disease research.
Their study identifies a promising method that could potentially slow or even stop the progression of the disease. Focusing on the role of reactive astrocytes and the plexin-B1 protein in Alzheimer’s disease, the research offers vital insights into how brain cells communicate. This opens up new avenues for innovative treatment approaches.
The findings were recently published in Nature Neuroscience . This groundbreaking work is centered on the manipulation of the plexin-B1 protein to enhance the brain’s ability to clear amyloid plaques, a hallmark of Alzheimer’s disease. Reactive astrocytes, a type of brain cell that becomes activated in response to injury or disease, were found to play a crucial role in this process.
They help control the spacing around amyloid plaques, affecting how other brain cells can access and clear these harmful deposits. “Our findings offer a promising path for developing new treatments by improving how cells interact with these harmful plaques,” said Roland Friedel, PhD, Associate Professor of Neuroscience, and Neurosurgery, at Icahn Mount Sinai and a senior author of the study. .
