Leakage of fluid from blood vessels, leading to oedema, is a key feature of many diseases including hyperoxic acute lung injury (HALI), which can occur when patients are ventilated with high concentrations of oxygen (hyperoxia). The molecular mechanisms driving vascular leak and oedema in HALI are poorly understood. VEGF-D is a protein that promotes blood vessel leak and oedema when overexpressed in tissues, but the role of endogenous VEGF-D in pathological oedema was unknown. To address these issues, we exposed Vegfd-deficient mice to hyperoxia. The resulting pulmonary oedema in Vegfd-deficient mice was substantially reduced compared to wild-type, as was the protein content of bronchoalveol..
