Tau isoform mapping across tissues and biofluids reveals a signature distinguishing Alzheimer’s disease from amyotrophic lateral sclerosis

Abstract Blood phosphorylated tau 217 (p-tau217) accurately detects Alzheimer’s disease (AD) pathology but is also elevated in amyotrophic lateral sclerosis (ALS), likely reflecting peripheral (big) tau released from muscle. Assays selectively measuring brain-derived (BD-) tau an...

Serum p-tau181 and p-tau217 levels in adolescents and adults with 5q spinal muscular atrophy

Abstract Background Reliable blood biomarkers for longitudinal monitoring in adolescent and adult 5q spinal muscular atrophy (SMA) are lacking. Phosphorylated tau (p-tau) species are elevated in serum in amyotrophic lateral sclerosis (ALS), where they may reflect peripheral nerve...
