doi: 10.1186/s12959-022-00384-0

Figure Lengend Snippet: Visual summary: the effect of complement C5a in arterial thrombosis. In arterial thrombosis, C5a chemotactically attracts neutrophils to migrate towards the culprit site and triggers the release of NETs, which contribute to thrombosis by promoting coagulation and stabilizing clots. C5a-induced promotion of NET release is dependent on Mito-ROS production. C5a induces the Mito-ROS production by inhibiting mitochondrial STAT3 activity
