In Alzheimer disease, these cells become fragmented and dysfunctional, impairing tau clearance and potentially accelerating neurodegeneration. &amp;nbsp; This work opens an intriguing avenue: could restoring tanycyte function enhance tau removal and slow Alzheimer progression? &amp;nbsp; A small cellular gatekeeper may hold an important clue in the battle against dementia. &amp;nbsp; Source: Sauvé F et al.
