Astrocyte-derived extracellular vesicle phosphorylated TDP-43 as a blood-based biomarker for amyotrophic lateral sclerosis.
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by central nervous system (CNS) neuroglial TAR DNA-binding protein 43 (TDP-43) pathology in ~90-95% of cases. Non-invasive biomarkers are critically needed to reduce diagnostic delay, enable patient stratification, and assess treatme...
