Host-pathogen interaction in Drosophila


Bruno Lemaitre and his research group are investigating mechanisms regulating the interactions between animals and microorganisms. They study both microbial infections (the host defense responses to a pathogenic situation), and symbiotic situations (when the interaction is mutually beneficial for the fly and the bacteria). They also explore what makes the gut an efficient barrier against infections, despite its constant contact with microbes. They use the fruit fly (Drosophila melanogaster) as a model animal, which shares molecular and physiological traits evolutionarily conserved with many animals, including humans.
