The signalling cascade involved in lung ischaemia–reperfusion-induced oedema is poorly understood. Using knockout mice, Weissmannet al. propose a model in which reactive oxygen species production by endothelial NOX2 leads to phospholipase C-γ activation, DAG kinase inhibition and subsequent TRPC6 activation.
Activation of TRPC6 channels is essential for lung ischaemia–reperfusion induced oedema in mice
