Acute lung injury (ALI) is caused by direct or indirect insults to the lung, and is associated with high morbidity and mortality. Bacterial superinfections are feared complications of ALI. On the cellular level, alveolar macrophages are key innate immune cells that initiate and resolve an inflammatory process. Resolution of inflammation might impair the macrophage´s ability to clear bacteria, thus predisposing to superinfections. My project focuses on the kinetics and activation state of macrophages/monocytes during ALI in the context of bacterial superinfections.
