Profiles of circulating T follicular helper (cTfh) cell subpopulations in patients with asthma, COPD and asthma-COPD overlap (ACO)

Key Points

• Circulating T follicular helper (cTfh) cell profiles differ among asthma, COPD, and ACO patients, highlighting their immune system variations.
• Key evidence includes specific cTfh cell subpopulation levels that show significant variation across these respiratory conditions.
• Observational analysis examines immune cell profiles across diverse patient groups, using blood samples collected for testing.
• Findings suggest the need for tailored therapies to address the varying immune responses in asthma and COPD patients.
