Influenza virus pathology

We are living in a densely colonized, poly-microbial environment and even our outer and inner body surfaces are largely covered with microbes. My group in the department of microbiology and molecular medicine studies the impact of acute respiratory infections on the colonization of mucosal surfaces with commensal ("good") and pathological bacteria. We were amongst the first to describe the disturbance of microbial community composition in the context of an influenza A virus (IAV) infection and the role inflammatory processes play in it. Now, we use this knowledge to develop novel antibacterial therapies based on probiotics. We study the function of viral accessory proteins on the innate/inflammatory host immune response on a molecular level. We recently found that a short viral peptide (PB1-F2) is responsible for the antagonism of the NLRP3 inflammasome. This multiprotein complex is responsible for the release of IL1-beta, a key cytokine in proinflammatory responses and important for the host response to viral infections.
Specific expertise
My group has all the genetic tools for manipulation of IAV and we have years of experience with in vitro and in vivo infection models. Using bioinformatic approaches we also characterize the composition of commensal microbial communities on mucosal surfaces under IAV infection conditions.
