Influenza A virus (IAV) is a major cause of lung infection worldwide, and its high mutation rate leads to the generation of novel influenza strains with potential for causing severe lung disease and new pandemics. Every year, at least 28,000 Americans develop critical illness from IAV lung infection. Mortality rates reach 30%, in part due to coinfection by Staphylococcus aureus (SA) that leads to fatal lung injury. However, it is unclear how IAV promotes SA infection, particularly in lung alveoli, the tiny air sacs where lung injury occurs. We will apply state-of-the-art imaging technology to gain new understanding of how influenza causes lung injury. We will focus on how influenza A virus disrupts the functioning of alveoli to cause secondary SA infection and the roles that certain proteins and certain alveolar cells play in this process. We will investigate the therapeutic potential of inhibiting these proteins in alveolar cells to restore normal function in lungs infected by IAV. Our overall goal is to identify new treatment approaches for influenza infection that decrease lung injury and increase survival.
