The Infectious Immunology group was established at the Research institute for Internal Medicine end of 2022. The overall research focus is to characterize and understand the interplay between infections and host immunology, aiming for more targeted and personalized treatment strategies. We perform clinical translational research within Infectious diseases including COVID-19 and HIV, and primary immunodeficiency including common variable immunodeficiency (CVID). This includes randomized controlled trials (RCTs) and observational studies with biobanking, with a particular focus on innate and adaptive immunity, inflammation as well as the gut microbiota. Our main patient materials are blood, airway and fecal samples, which we use for microbiome analyses, viral analyses, metabolomic analyses, as well as inflammatory profiles and host immunology.
