Neutrophil responses in pneumococcal pneumonia and acute lung injury
Migration and resolution, lung microenvironment and mechanisms: examining the diverse responses of neutrophils during S. pneumoniae pneumonia and acute lung injury
Researchers will track how neutrophils (a type of white blood cell) change and where they go during pneumococcal pneumonia and acute lung injury to find ways to protect lungs and help recovery.

What this research studies
This project follows neutrophils — the immune cells that flood infected lungs — during Streptococcus pneumoniae pneumonia and acute lung injury. The team will measure changes in neutrophil gene activity, surface markers, and cytokine profiles and map their locations within lung airspaces and tissue microenvironments. They will compare timing and spatial patterns to see when neutrophils help clear infection and repair tissue versus when they worsen lung injury. Results come from laboratory analyses of infected lung tissue and immune cells and aim to point toward new treatment targets.
Who could benefit from this research
Good fit: People who have or recently had pneumococcal (Streptococcus pneumoniae) pneumonia or acute lung injury/ARDS would be the most relevant candidates for related studies or sample donation.
Not a fit: People without bacterial pneumonia or whose lung problems are caused by non-infectious conditions may not benefit directly from this research.
Why it matters
Potential benefit: If successful, the work could identify targets to reduce lung damage and speed recovery from pneumococcal pneumonia and ARDS.
How similar studies have performed: Prior studies have shown neutrophils are diverse and can harm or help the lung, but translating those findings to new treatments remains limited, making this spatial and transcriptomic approach relatively novel.
