Researchers at the Icahn School of Medicine at Mount Sinai have made a significant breakthrough in Alzheimer’s disease research by identifying a novel way to potentially slow down or even halt disease progression. The study, which focuses on the role of reactive astrocytes and the plexin-B1 protein in Alzheimer’s pathophysiology, provides crucial insights into brain cell communication and opens the door to innovative treatment strategies. It was published in Nature Neuroscience on May 27.
