WebApr 13, 2024 · By spatial proteomics of thrombus samples, we identified key components of the coagulation system (e.g., factor X, factor V), platelets [e.g., glycoprotein (GP)V, GPIbα] and neutrophils (e.g., neutrophil elastase) in both brown bears and patients with VTE ( Fig. 1, D and E, and table S2). WebApr 14, 2024 · The activated partial thromboplastin time (aPTT) and prothrombin time (PT), two coagulation parameters altered by CSL in vitro, were assessed first. We used the direct FXa inhibitor rivaroxaban as a positive control for our experiments. CSL considerably slowed the aPTT at doses between 5 and 20 M ( Figure 2 A).
