However, similar to the results from the SARS-CoV-2 virus experiments, we were able to demonstrate that the Spike protein dose-dependently enhanced platelet aggregation and ATP release (Additional file 1: Online Figure 6 ). In addition, the Spike protein potentiated platelet aggregation and ATP release in response to agonists in vitro and enhanced thrombosis formation in vivo on hACE2 transgenic mice, while it had no effect on wild-type mice ( Fig. 6c and Additional file 1: Online Figure 8 ). ./cache/cord-297236-wnuvofwr.txt ./txt/cord-297236-wnuvofwr.txt
