First paper from CHEN lab!🩸->🧠Can we use p-tau217 value to estimate PET-like map of AD pathology?🤔 We say YES!💡In two datasets (A4, ADNI), p-tau217 level can predict concurrent Ab (but NOT Ab change) and future tau accumulation almost everywhere! https://t.co/kHNyxH58CH

Hi Early Career Researchers (ECR) in neuroscience!🧠 I've had a great time working as an ECR advisory board member for the Journal of Neuroscience @SfNJournals and learned so much from my peers and journal editors! We now invite you to join us! @SfNtweets https://t.co/wvD1shcKo4

With the first blood test for AD approved for clinical use, there may be great use of it to infer regional pathology when PET is not an option. Hasom Moon (the first author!) is now studying the discordant cases to better understand and maximize the use of blood-based biomarkers!

With these relationships, we can use p-tau217 to estimate the staging/severity of tau in the brain🧠. The comparison between p-tau217-estimated tau map and actual tau PET shows high similarities(!) for both cross-sectional estimation (top) and longitudinal prediction (bottom)!

🚨Please check out our new paper on a double (triple?) dissociation between AD pathology and cog: frontal-parietal Aβ accumulation related to executive function (EF) decline, but not memory; temporal tau accumulation related to memory decline, but not EF! https://t.co/BHbrJIEQhr

[Xi Chen @xichen.bsky.social @_Xi_Chen__]

THANKS to my coauthors @tessamharrison @susan_landau & those not on X for this exciting work! It gives us more hope in localizing early pathology and neural deficits driving differential cog declines, which is part of my current research! (I'm recruiting PhD🧑‍🎓 if u r interested!)
