PEDREIRA, P.R.; GARCIA-PRIETO, E.; ALBAICETA, G.M.  and  TABOADA, F.. Inflammatory response and apoptosis in acute pulmonary injury. Med. Intensiva [online]. 2006, vol.30, n.6, pp.268-275. ISSN 0210-5691.

One of the principal mechanisms of pulmonary injury in acute respiratory distress is due to the effects of the precipitated inflammatory response. The damage produced to the alveolar epithelium and underlying endothelium depends on the sequestration and activation of inflammatory cells, which in turn exert their actions through mediators. On the other hand, apoptosis is a mechanism responsible for epithelial damage and regulation of inflammation. Response of the lung tissue subjected to mechanical ventilation stimulus is added to the previous mechanisms. All these processes flow into a series of common pathways of cellular activation. Knowledge of these  mechanisms could serve to identify which patients would benefit from a specific treatment before applying therapies that act indiscriminately in the inflammatory response.
