An epithelial integrin regulates the amplitude of protective lung interferon responses

ABSTRACT: Integrins facilitate intercellular movement and communication. Unlike the promiscuous activities of many integrins, β6 integrin is restricted to epithelia and partners exclusively with integrin αV to modulate acute lung injury (ALI). Given that ALI is a complication of respiratory infection, we used mice lacking β6 integrin (β6 KO) to probe the role of the epithelial layer in controlling the lung microenvironment during infection. We found β6 KO mice were protected from disease caused by influenza and Sendai virus infections. They were also protected from disease caused by Streptococcus pneumoniae infection alone and after prior influenza virus infection, the co-infection representing an often-lethal condition in humans. Resistance in the absence of epithelial β6 integrin was caused
