Reactive respiratory epithelial cells
WebReactive oxygen species (ROS) may subject epithelial cells to oxidative stress, which is believed to occur in COPD and asthma. I. Rahman (Rochester, NY, USA) discussed how ROS may activate signalling pathways, thus leading to the activation of transcription factors (NF-κB and activator protein-1) and chromatin remodelling [ 21 ].

WebRotenone, a mitochondrial complex I inhibitor, partially abrogated the stretch-induced generation of O2- after 2 h CMS in 16HBE cells. NADPH oxidase activity was increased after 2 h of CMS, contributing to the production of O2-. Increased ROS production in lung epithelial cells in response to elevated stretch may contribute to the onset of VILI.
