Tanycytes' Role in Alzheimer's Tau Clearance

Researchers, led by Vincent Prevot of France===Inserm, have discovered a previously unknown mechanism for tau protein accumulation in Alzheimer s disease. The study, published in Cell Press Blue, reveals that specialized brain cells called tanycytes play a key role in clearing toxic tau from the cerebrospinal fluid into the bloodstream. In Alzheimer's patients, these tanycytes are fragmented and show altered gene expression, impairing their ability to clear tau. This finding suggests that maintaining tanycyte health could be a new strategy to improve tau clearance and slow disease progression. The research was supported by the International===European Research Council, United States===National Institutes of Health, Fondation pour la Recherche Médicale, and Fondation NRJ for Neuroscience-Institut de France.
