Scientists discover hidden brain cells that may stop Alzheimer’s tau buildup
General • March 8, 2026
Scientists have
uncovered a
surprising new role for little-known brain cells
called tanycytes that may influence the development of Alzheimer’s disease. These specialized cells appear to help remove toxic tau protein from the brain by transporting it from the cerebrospinal fluid into the bloodstream. When tanycytes become damaged or dysfunctional, tau can accumulate in the brain, a hallmark of Alzheimer’s.
