Investigating the Tau proteoform landscape of human brain using a single‐molecule analysis platform [PDF]

Alzheimers Dement
Abstract Background The microtubule‐associated protein Tau (MAPT) is implicated in various progressive neurodegenerative diseases, including Alzheimer's Disease (AD). With six primary splicing isoforms and over 70 different post‐translational modifications (PTMs) identified on Tau, its proteoform diversity is extensive. However, a significant knowledge
