ClinConnect Summary

This observational study will specifically investigate different immunological parameters in blood and at the site of infection in patients with IAV symptoms or confirmed infection to understand parameters related to disease course. Blood and airway samples will be analyzed for immune cell subsets and their functionality, antibodies and other soluble mediators and linked to clinical data. Immune cells will be analyzed using multi-color flow cytometry, RNA sequencing, and in vitro functionality assays. Fluids (plasma, serum, supernatants from airway samples and cell culture supernatants) wil...
