Divergent roles of serum CXCL9 as a biomarker in ILD and COPD: a comparative study

Puntos clave

• CXCL9 levels correlate with divergent roles in ILD and COPD, revealing distinct biomarker functions.
• As a prognostic marker, CXCL9 may identify treatable inflammation in ILD while reflecting the inflammatory burden in COPD.
• Observational analysis of serum CXCL9 levels demonstrates its significance in inflammatory conditions related to lung diseases.
• These findings suggest that CXCL9 could guide treatment strategies based on its specific role in each condition.
