Plasma exchange efficiently reduces total, programmed death-ligand 1 (PD-L1)-positive, and ADAM10-positive extracellular vesicle (EV) levels in vivo. Plasma levels of total EVs immediately prior to (pre) and after (post) therapeutic plasma exchange (TPE) are plotted. TPE significantly reduced (A) total (p<0.0001), (B) PD-L1-positive (p=0.028), and (C) ADAM10-positive (p<0.0001) but not (D) CD61-positive EVs (p=0.94) by Wilcoxon signed-rank test.
