Results of the plasma proteomic analysis using SWATH-MS. Shown are the results of the comparison between plasma of patients with GPS (n = 11) and age-matched controls. A total of 51 discriminatory proteins were identified, with 11 proteins being more abundant (up direction) and 40 proteins being less abundant in plasma of patients with GPS (down direction) compared with plasma of healthy controls, as reported by Sims et al.26 Presence of SG proteins (5 proteins in total, indicated in bold and in the SG/GG column) in the plasma of GPS patients was found among other significantly increased plasma proteins.
HSP, heat shock protein.
