[email protected] pathophysiological processes including hyperinflammation, endothelial damage, thrombotic microangiopathy, and end-organ damage. Limited knowledge about the molecular mechanisms Competing interest: See driving these processes and lack of staging biomarkers hamper the ability to stratify patients for page 23 targeted therapeutics.
