Mapping and understanding alveolar cells in smokers with COPD

Mapping and Characterization of Alveolar Cells During Smoking and Chronic Obstructive Disease

NA · Centre Hospitalier Intercommunal Creteil · NCT05227547

This study is trying to understand how certain lung cells behave in smokers with COPD compared to non-smokers to learn more about how smoking affects lung repair.

What this trial studies

This study evaluates the regenerative abilities of mesenchymal cells in the alveolar type 2 cells of patients undergoing thoracic surgery for suspected cancer. It focuses on smokers with and without chronic obstructive pulmonary disease (COPD) and compares them to non-smokers. The research aims to uncover the mechanisms behind the depletion of alveolar progenitor cells and their role in the pathophysiology of COPD. By analyzing the interactions between different cell populations in the alveolar stem cell niche, the study seeks to provide insights into lung repair processes affected by smoking and COPD.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are undergoing lung resection surgery for cancer or suspected cancer and are smokers with or without COPD.

Not a fit: Patients with chronic autoimmune diseases, those undergoing neo-adjuvant chemotherapy, or individuals who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic strategies for enhancing lung repair in patients with COPD.

How similar studies have performed: While similar studies have explored cell interactions in lung diseases, this specific approach to mapping alveolar cells in smokers with COPD is relatively novel.
