Tau degradation
WebHere, we reveal how tau seeds contained within internalized exosomes exploit mechanisms of lysosomal degradation to escape the endosome and induce tau aggregation in the cytosol of HEK293T-derived 'tau biosensor cells'. We found that the majority of the exosome-containing endosomes fused with lysosomes to form endolysosomes.

WebBoth ribosomal-defective tau and tau targeted for turnover are subject to immediate degradation. The exact mechanisms of tau degradation in the human brain are unknown, but have been demonstrated in vitro using the 20S proteasome core [ 12] and non-proteasomal proteases (proteases), such as cathepsin-D [ 13 ], caspases [ 14] and … WebNational Center for Biotechnology Information

WebApr 5, 2024 · The tauopathies are a diverse group of neurodegenerative diseases that are defined by the misfolding of tau—a microtubule binding protein—and its assembly into filamentous intracellular deposits. Primary tauopathies, in which tau inclusions are the principal pathological hallmark, highlight the neurotoxic nature of tau.
