Molecular signatures associated with Mx1-mediated resistance to highly pathogenic influenza virus infection: mechanisms of survival


ABSTRACT: Understanding the role of host factors during lethal influenza virus infection is critical to deciphering the events that will determine the fate of the host. One such factor is encoded by the Mx1 gene, which confers resistance to influenza virus infection. Here, we compared pathology and global gene expression profiles in lung tissue from BALB/c (Mx1(-)) and BALB•A2G-Mx1 mice (Mx1(+/+)) infected with the fully reconstructed 1918 pandemic influenza virus with an without interferon-alpha pretreatment. Mx1(+/+) mice showed less tissue damage than Mx(-) animals, and pathology and mortality were further reduced by treating the mice with interferon prior to infection. The goal of the global transcriptional profiling was to identify distinct molecular signatures associated with partial protection, complete protection, and the contribution of interferon to the host response.
