Scientists study immune cells to unlock sepsis secrets
NCT ID NCT04103281
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at neutrophils, a type of white blood cell, in children with sepsis (a severe infection). Researchers want to understand how these cells change and may cause lung injury. By comparing sepsis patients to healthy controls, they hope to find clues for future treatments. This is an observational study, not a treatment trial.
