Thèmes de recherche

The focus of our work is the mechanism by which bacterial toxins, in particular diphtheria and botulinum toxins, cross biological membranes and infect cells. We are investigating at the sub-molecular level conformational changes of the toxin translocation domains during their interaction at acid pH with membrane models.
 
We are developing biotechnological applications derived from bacterial toxins as well as animal and plant toxins. These applications concern the production of targeted toxin and anti-cancer vaccines. We are searching for botulinum toxins and ricin inhibitors by high throughput screening using cellular functional assays.
