Hyperferritinemic syndrome is a collective term for a group of severe inflammatory conditions distinguished by high ferritin levels, including adult-onset Still’s disease and COVID-19. Here authors show in an animal model that high ferritin levels are not just a sign of hyperinflammation but also a pathogenic factor that triggers neutrophil leukocyte activation and extracellular trap formation.
