Acute lung injury (ALI) results in acute respiratory disease that causes fatal respiratory diseases; however, little is known about the incidence of influenza infection in ALI. Using a ALI-mouse model, we investigated the pro-inflammatory cytokine response to ALI and influenza infection. Mice treated with bleomycin (BLM), which induces ALI, were more resistant to influenza virus infection and exhibited higher levels of type I interferon (IFN-I) transcription during the early infection period than that in PBS-treated control mice. BLM-treated mice also exhibited a lower viral burden, reduced pro-inflammatory cytokine production, and neutrophil levels. In contrast, BLM-treated IFN-I receptor 1 (IFNAR1)-knockout mice failed to show this attenuated phenotype, indicating that IFN-I is key to the antiviral response in ALI-induced mice. The STING/TBK1/IRF3 pathway was found to be involved in IFN-I production and the establishment of an antiviral environment in the lung. The depletion of plasmacytoid dendritic cells (pDCs) reduced the effect of BLM treatment against influenza virus infection, suggesting that pDCs are the major source of IFN-I and are crucial for defense against viral infection in BLM-induced lung injury. Overall, this study showed that BLM-mediated ALI in mice induced the release of double-stranded DNA, which in turn potentiated IFN-I-dependent pulmonary viral resistance by activating the STING/TBK1/IRF3 pathway in association with pDCs.

ABSTRACT Natural killer (NK) cells are an important component in the control of influenza virus infection, acting to both clear virus-infected cells and release antiviral cytokines. Engagement of CD16 on NK cells by antibody-coated influenza virus-infected cells results in antibody-dependent cellular cytotoxicity (ADCC). Increasing the potency of antibody-mediated NK cell activity could ultimately lead to improved control of influenza virus infection. To understand if NK cells can be functionally enhanced following exposure to influenza virus-infected cells, we cocultured human peripheral blood mononuclear cells (PBMCs) with influenza virus-infected human alveolar epithelial (A549) cells and evaluated the capacity of NK cells to mediate antibody-dependent functions. Preincubation of PBMCs with influenza virus-infected cells markedly enhanced the ability of NK cells to respond to immune complexes containing hemagglutinin (HA) and anti-HA antibodies or transformed allogeneic cells in the presence or absence of a therapeutic monoclonal antibody. Cytokine multiplex, RNA sequencing, supernatant transfer, Transwell, and cytokine-blocking/cytokine supplementation experiments showed that type I interferons released from PBMCs were primarily responsible for the influenza virus-induced enhancement of antibody-mediated NK cell functions. Importantly, the influenza virus-mediated increase in antibody-dependent NK cell functionality was mimicked by the type I interferon agonist poly(I·C). We conclude that the type I interferon secretion induced by influenza virus infection enhances the capacity of NK cells to mediate ADCC and that this pathway could be manipulated to alter the potency of anti-influenza virus therapies and vaccines. IMPORTANCE Protection from severe influenza may be assisted by antibodies that engage NK cells to kill infected cells through ADCC. Studies have primarily focused on antibodies that have ADCC activity, rather than the capacity of NK cells to become activated and mediate ADCC during an influenza virus infection. We found that type I interferon released in response to influenza virus infection primes NK cells to become highly reactive to anti-influenza virus ADCC antibodies. Enhancing the capacity of NK cells to mediate ADCC could assist in controlling influenza virus infections.

ABSTRACT We have studied the pathogenesis of influenza virus infection in mice that are unable to respond to type I or II interferons due to a targeted disruption of the STAT1 gene. STAT1−/− animals are 100-fold more sensitive to lethal infection with influenza A/WSN/33 virus than are their wild-type (WT) counterparts. Virus replicated only in the lungs of WT animals following intranasal (i.n.) virus inoculation, while STAT1−/− mice developed a fulminant systemic influenza virus infection following either i.n. or intraperitoneal inoculation. We investigated the mechanism underlying this altered virus tropism by comparing levels of virus replication in fibroblast cell lines and murine embryonic fibroblasts derived from WT mice, STAT−/− mice, and mice lacking gamma interferon (IFNγ−/− mice) or the IFN-α receptor (IFNαR−/− mice). Influenza A/WSN/33 virus replicates to high titers in STAT1−/− or IFNαR−/− fibroblasts, while cells derived from WT or IFNγ−/− animals are resistant to influenza virus infection. Immunofluorescence studies using WT fibroblast cell lines demonstrated that only a small subpopulation of WT cells can be infected and that in the few infected WT cells, virus replication is aborted at an early, nuclear phase. In all organs examined except the lung, influenza A WSN/33 virus infection is apparently prevented by an intact type I interferon response. Our results demonstrate that type I interferon plays an important role in determining the pathogenicity and tissue restriction of influenza A/WSN/33 virus in vivo and in vitro.
