Figure Lengend Snippet: Surface glycans on l-PEVs in human and mice. The binding of fluorescein-conjugated RCA-1 (A), sWGA (B), SNA (C), MAL (D), ConA (E), and UEA lectins (F) to mouse and human l-PEVs was measured using flow cytometry. Data are represented as mean fluorescence intensity (MFI) in arbitrary units (a.u.). Orange, blue, and green lines indicate comparison between human and murine samples in resting, CRP + PAR1/4-AP stimulated (CT), or A23187 stimulated conditions, respectively. Quantification of carbohydrates in lysates of l-PEVs and platelets was performed using a microarray containing 95 lectins. (G) Comparison between total lectin binding to human and murine l-PEVs. (H) Comparison between total lectin binding to human and mouse platelets. Murine l-PEVs contained less carbohydrates, including galactose (I), N -acetylglucosamine (J), sialic acid (K), T-antigen core sugars (L), mannose (M), fucose (N), and N -acetylgalactosamine (O). Data are represented in relative fluorescence units after normalization of signal on positive and negative controls for protein binding to lectins. Data were obtained after IQR outlier test was performed. Data are mean ± SD; n = 8 to 12; ∗ P < .05, ∗∗ P < .01, ∗∗∗ P < .001, ∗∗∗∗ P < .0001. ConA, concanavalin A; GlcNAc, β-galactose and N -acetylglucosamine; MAL, Maackia amurensis ; PEV, platelet-derived extracellular vesicle; RCA, Ricinus communis agglutinin; SNA, Sambucus nigra ; sWGA, succinylated wheat germ agglutinin; UEA, Ulex europaeus agglutinin.
