We now have a blood biomarker that is even more strongly associated with tau PET and cognitive symptoms than even p-tau217! Plasma eMTBR-tau243 will help us to understand whether cognitive impairment is likely to be related to Alzheimer's pathology. #ENDALZ

Breakdown of the paper:

This study aimed to develop a new blood test that can measure a specific type of tau protein called endogenously cleaved microtubule-binding region containing residue 243 (eMTBR-tau243). This tau protein is found in...

"plasma eMTBR-tau243 might be a viable alternative to tau-PET for identifying suitable study participants in clinical trials...even more importantly, it might be used as an important study endpoint to cost-effectively determine whether a new therapy affects insoluble tau proteinopathy in the brain."

Great explanation. I read the paper 🔽 and press release, but didn't understand why the tau protein should be an earlier, reliable biomarker than others suggested in the last decade.

This is a bit development in Alzheimer’s disease.

Not only is this new Blood Based Biomarker (BBM) 92% accurate but it can differentiate between early and late stage disease.
