Glucagon-like peptide-1 stimulates acute secretion of pro-atrial natriuretic peptide from the isolated, perfused pig lung exposed to warm ischemia.

Glucagon-like peptide-1 (GLP-1) has proven to be protective in animal models of lung disease but the underlying mechanisms are unclear. Atrial natriuretic peptide (ANP) is mainly produced in the heart. As ANP possesses potent vaso- and bronchodilatory effects in pulmonary disease, we hypothesised that the protective functions of GLP-1 could involve potentiation of local ANP secretion from the lung.

Tolerable Duration of Warm Ischaemia After Circulatory Death Is Safe For At Least One Hour in Porcine Lungs: Functional Assessment with Ex Vivo Lung Perfusion.

Background: Lungs from donation after circulatory death (DCD) may be an underused resource for transplantation. The aim was to investigate, with a DCD pig model, if it was possible to recondition lungs exposed for up to 2 h of warm ischaemia with ex vivo lung perfusion (EVLP).

Methods: Danish domestic pigs (N = 17) were randomized into three groups.
