Description of Research
We have a long-standing interest in basic questions related to generation of effective immune responses, mechanisms of protective immunity, and the establishment of long-term immunological memory. For these basic studies, we have used two well-characterized murine models of infection with lymphocytic choriomeningitis virus (LCMV) and Listeria monocytogenes. More recently, we have become interested in viral/bacterial co-infections, which occur frequently in clinics and often results in more severe disease than infection by an individual pathogen. A striking example of this is the high mortality caused by secondary bacterial pneumonia following flu infection. We are studying how inflammation induced by a bacterial pathogen may affect the host response to a co-infecting viral pathogen and protective immunity. We are investigating the mechanisms of bacterial pathogenesis that contribute to lethal secondary bacterial pneumonia following flu infection. Through these studies, we have gained new insights into complexity of tripartite interactions between the virus, bacterium and host immune system. We are developing novel, combinational vaccine approaches tailored towards co-infection.
