Popis: Abstract The clinical diagnosis of major depressive disorder (MDD) still depends on subjective information in terms of various symptoms regarding mood. Detecting the characterization of extracellular vesicles (EVs) in blood may result in finding a diagnostic biomarker that reflects the depressive stage of patients with MDD. Here, we report the results on the glycosylation pattern of enriched plasma EVs from patients with MDD. We compared glycosylation patterns by lectin blotting expressed in EVs isolated from the plasma of both patients with MDD and age-matched healthy control participants (HCs) using size-exclusion chromatography. The levels of Wheat germ agglutinin (WGA), N-acetyl glucosamine (GlcNAc), and N-Acetylneuraminic acid (Neu5Ac, sialic acid) - binding lectin, were significantly decreased in patients with MDD in the depressive state compared to HCs and in remission state. Furthermore, proteome analysis revealed that the von Willebrand factor (vWF) was a significant factor recognized by WGA. WGA-binding vWF antigen differentiated patients with MDD versus HCs and the same patients with MDD in a depressive versus remission state. In this study, the change patterns in the glycoproteins contained in plasma EVs support the usability of testing to identify patients who are at increased risk of depression during antidepressant treatment.
