Research in the Jeffrey Dodd-o Lab aims to better understand the contributing factors of lung ischemia/reperfusion injuries and the role these injuries play in the lung dysfunction of patients soon after cardiopulmonary bypass surgery. We have created an ischemia/reperfusion model in a spontaneously breathing mouse that they use with an in situ mouse lung preparation to identify cardiopulmonary interactions that impact reperfusion-related lung injury. We are working to characterize the influence of atrial natriuretic peptide (ANP) on lung microvascular permeability.
