A biomarker of Alzheimer’s disease could be a useful diagnostic tool for other amyloidoses - Nature Medicine Increased blood levels of phosphorylated tau (p-tau) are a diagnostic tool in Alzheimer’s disease. In a multicenter, cross-sectional study, we show that serum p-tau could also serve as a biomarker for...

It was great fun to measure NfL in all these species—not many people have the chance to analyze blood from elephants, crocodiles, lizards, and turtles. To better understand age-related changes and predict mortality across an even wider range of species, we now require additional samples.

Neurofilament light chain may serve as a cross-species blood biomarker to assess aging and predict mortality.

Neurofilament light chain may serve as a cross-species blood biomarker to assess aging and predict mortality Blood levels of neurofilament light chain (NfL) increase with age in healthy humans and can predict all-cause human mortality, but is this true across species? This study shows that NfL age-related bl...
