The Flaño laboratory studies how the immune system responds to viral infections, with a special emphasis on respiratory virus infections --influenza virus and respiratory syncytial virus-- and persistent herpesvirus infections.
The overall goal of the laboratory is to understand the interplay between the innate and adaptive immune systems, and how they contribute to the generation of long-term protective immunity during infection and vaccination. To this extent, the laboratory studies human clinical samples and mouse models of infection and vaccination using methods such as gene expression analysis and multicolor flow-cytometry.
Flaño's lab has recently shown that airway epithelial cells mount pathogen specific responses and that regulate the function of T cells in the lung through innate interferons and the PD-L1/PD-1 axis. These findings suggest that PDL-1 expression by airway epithelial cells during the early phase of the response to influenza virus infection represents a mechanism for regulating lung immune homeostasis and reveal a promising strategy to modulate local epithelial-T cell interaction in the airways.
