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...
