T regulatory cells activation and distribution are modified in critically ill patients with acute respiratory distress syndrome: A prospective single-centre observational study

Acute respiratory distress syndrome (ARDS) is a common and fatal inflammatory condition. Whether T regulatory cells (Tregs) are beneficial or detrimental remains controversial, and longitudinal studies are lacking. Phenotyping of Tregs activation markers has been poorly reported. We aimed to evaluate quantitative and functional alterations in blood and bronchoalveolar Treg phenotype of ARDS patients. We performed a single-centre observational...
