WebFeb 25, 2024 · Tau Spreading Mechanisms Although tau is predominantly an intracellular protein, recent evidence shows that, besides the amount of tau released by dying neurons, the protein can be also actively secreted to the extracellular space both in vitro and in vivo. WebTau fibril spreading is a major factor contributing to the progression of Alzheimer’s disease (AD). Lysosomal membrane damage by internalized tau fibrils is a key step in tau spreading, suggesting that efficient rapid lysosomal membrane repair would suppress tau spreading and AD progression.
