Hello My name is Dominique Ferrandon. I've been working on Drosophila innate immunity in Strasbourg for more than 15 years. Today, I'm going to present how Drosophila are used to model intestinal infections and shows that, thanks to its advanced genetics, it provides a powerful paradigm to understand the different facets of mucous host defenses.

The first question to address is- why one should use Drosophila to study innate immunity? Many fly stocks can be raised at relatively low cost. Also Drosophila has a short life cycle and produces an abundant offspring. As will be illustrated in this talk, its main strength, however, lies in its genetics, especially the ability to perform genome-wide screens in a living animal. As regards immunity, flies like a conventional adaptive immunity. And first, it is easier to correlate the effect of mutations in immunity genes to a phenotype of susceptibility to a given pathogen.
