Influenza A viruses are characterized by a high degree of genomic plasticity which enables them to quickly adapt to new environmental conditions and to cross species barriers, causing epidemics and occasional pandemics. In the first funding period, CRISPR-Cas9-mediated gene editing was employed to generate mouse lung epithelial cells deficient in specific key proteins of the NF-B pathway. The functional analysis of these cells revealed that NF-κB was not relevant for replication of a mouse-adapted SC35M, while the absence of NF-κB activity increased replication of the non-adapted SC35 virus. The analysis of reassortant viruses showed that the anti-viral effect of NF-B is determined by the IAV genotype. In addition, the group has identified thousands of IAV-regulated phosphorylation sites of host cell and viral proteins were identified in a phospho-proteomic screen, which led to the discovery of new IAV-regulated kinase pathways, phosphorylation motifs, and cellular processes. This first comprehensive phospho-proteomic screen now allows to study the contribution of key phosphorylation sites and newly discovered pathways for IAV replication.

Based on their cell biological experience, the Kracht group has made a major and systematic effort to determine the entire transcriptomes, proteomes and phospho-, acetyl-, and ubiquityl proteomes of human coronavirus (HCoV) 229E-infected cells at high resolution. These data sets revealed hundreds of new HCoV-229E-regulated cellular genes and proteins and also demonstrated that the HCoV-229E M- and N-proteins are heavily phosphorylated and acetylated. Furthermore, the Kracht group determined the chromatin landscape of HCoV-229E-infected cells and found more than 1000 CoV-regulated enhancers. This comprehensive insight into transcriptional and post-transcriptional mechanisms in response to coronavirus infection offers multiple avenues for further investigation of virus-host interactions at the molecular level.

Research areas: Molecular Virology, Immunology, Allergy

Respiratory RNA viruses play an important role in the initiation and exacerbation of chronic inflammatory lung disease, including allergic asthma. Clinically relevant pathogens include influenza virus (IAV), rhinovirus (RV), and respiratory syncytial virus (RSV). In the first funding period, the Renz and Skevaki groups focused on the role of IAV infections in the development of allergic asthma, utilizing a well-established murine animal model of experimental asthma. Surprisingly, they found that a single preceding H1N1 IAV infection rendered the mice resistant to subsequent development of allergic airway inflammation, airway hyperresponsiveness and Th2-immune responses. This protection was dependent on the presence of both CD4+ and CD8+ T effector memory cells. By means of comprehensive in silico analyses, ex vivo T-cell peptide stimulation, and in vivo immunization experiments, two MHC-class I H1N1 peptides and two MHC-class II H1N1 peptides, which cross-react with three ovalbumin-derived peptides, were identified. These data illustrate for the first time heterologous immunity of virus-infected animals towards an allergen.

Influenza A virus (IAV) pneumonia is characterized by severe airway and alveolar injury, followed by stem cell-mediated epithelial repair. This project aims at (i) understanding which host signalling pathways at the virus-host interface drive alveolar epithelial cell repair from distinct lung stem cell niches and (ii) elucidating how viral pathogenicity factors impact these mechanisms, resulting in aggravated damage of the distal lung epithelium and in impaired or aberrant repair after IAV-induced pneumonia. In the previous funding period, the Herold group characterized mechanisms that result in impaired alveolar epithelial barrier function after IAV infection in vivo. Particularly, a newly defined pool of local lung epithelial stem/progenitor cells (EpiSPC) was found to be essential for bronchoalveolar tissue regeneration after IAV-induced injury. Their regenerative response depended on cooperation with mesenchymal cells of the stem cell niche and involved a β-catenin/FGF10/FGFR2b signalling axis as well as epithelial GM-CSF. Furthermore, it was demonstrated that IAV infection of the stem cell niche critically impacts the capacity of EpiSPC to mediate coordinated tissue repair. The distinct role and regulation of GM-CSF in EpiSPC-mediated repair as well as the detailed consequences of IAV infection of the stem cell niche with respect to restitutio ad integrum of the injured lung tissue will be elucidated in the 2nd funding period.
