Sestrins (Sesns) are a family of highly conserved stress-inducible proteins and various stresses have been shown to strongly up-regulate them. Sestrin 2 (Sesn2) deficiency has been shown to partially suppress pulmonary emphysema. The aim of this study was to evaluate Sesn2 levels in COPD patients and its possible associations with the presence of emphysema and blood eosinophils.

In this study, we evaluated the associations of eosinophils with the presence of emphysema in COPD patients. Induced sputum and blood eosinophil measurements were performed in consecutive COPD patients.
