Functional Activity of TDP-43: A Direct Biomarker for ALS

TDP-43 dysfunction is a defining feature of amyotrophic lateral sclerosis (ALS), yet no biofluid biomarker directly measures its functional activity. We developed a serum-based homogeneous time-resolved FRET (hTR-FRET) assay that quantifies TDP-43 RNA binding activity using synth...

Endothelial Cell Proteins as Biomarkers in Susac Syndrome

ABSTRACT Objective Susac syndrome (SS) is a rare CD8 + T cell–mediated microangiopathy affecting the brain, retina, and auditory labyrinth. Endothelial injury is thought to be a central mechanism; however, no circulating disease biomarkers are known. We performed targeted proteom...
