The ability of the influenza A virus genome to undergo minor changes through “antigenic drift” and major changes through “antigenic shift” poses significant challenges in developing effective annual vaccines. More importantly, these genetic alterations may yield novel strains leading to the next global pandemic. Severe respiratory disease from influenza A viruses leads to acute respiratory distress syndrome where viral replication occurs in the epithelial cells lining the alveolus. Damage to the alveolar type I (ATI) and type II (ATII) cells leads to flooding of the alveolus with edematous fluid, fibrin, erythrocytes, and other inflammatory mediators. This study investigated the effects of influenza A virus infection on those alveolar epithelial cells in a mouse model. We demonstrated that influenza infection reduces the number of ATII cells as well as dramatically alters their production of surfactant proteins. We observed a transition of ATII cells into a ATI cell phenotype by measuring the production of at ATI cell specific marker T1a/Podoplanin by ATII cells isolated from mice post infection. Continued examination and characterization of ex-vivo isolated ATII cells can provide important information into the role of ATII cells in restoring the normal epithelial lining of a damaged alveolus. Restoration of an intact respiratory epithelium is essential in the recovery from acute lung injury. 2014-11-03 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1406201295 http://rave.ohiolink.edu/etdc/view?acc_num=osu1406201295 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
