研究领域

The Host-Microbe Interaction lab is interested in understanding the interplay established between bacteria and their host during infection. We are currently focusing on the enteropathogen Shigella flexneri, which use a Type Three Secretion Apparatus (T3SA) to inject some of its proteins inside human intestinal cells. Our main interests are: 1) T3SA functioning and regulation; 2) bacterial strategies for hijacking the biological processes of the host; 3) bacterial and host adaptation at play during infection. Our long-term objective is to identify novel therapeutic avenues to treat infectious diseases.
