Observational analysis revealed elevated complement and neutrophil activity during acute chest syndrome in sickle cell disease, suggesting a link to lung damage.
Key Points
Increased neutrophil activation is associated with elevated complement levels in sickle cell disease.
Murine models demonstrate a crucial link between complement activation and neutrophil extracellular trap formation.
Complement deposition and immature neutrophil phenotypes rise during acute chest syndrome episodes, highlighting potential targets for intervention.
These findings emphasize the role of complement in driving inflammation and damage in the lungs of sickle cell disease patients.
