Functional analysis of RIP toxins from the Drosophila endosymbiont Spiroplasma poulsonii
Bruno Lemaitre, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez
BackgroundInsects frequently live in close relationship with symbiotic bacteria that carry out beneficial functions for their host, like protection against parasites and viruses. However, in some cases, the mutualistic nature of such associations is put in ...
2019The melanization reaction in Drosophila: More than black or white
The melanization reaction is a rapid and important immune mechanism in arthropods. It results in the production of melanin at the site of injury and around invading microbes. The enzymes responsible for melanogenesis are phenoloxidases (PO), which catalyze ...
EPFL2018Thioester-containing proteins regulate the Toll pathway and play a role in Drosophila defence against microbial pathogens and parasitoid wasps
Bruno Lemaitre, Samuel Rommelaere, Anna Dostalova
Background: Members of the thioester-containing protein (TEP) family contribute to host defence in both insects and mammals. However, their role in the immune response of Drosophila is elusive. In this study, we address the role of TEPs in Drosophila immun ...
2017The Role of Lipid Competition for Endosymbiont-Mediated Protection against Parasitoid Wasps in Drosophila
Bruno Lemaitre, Fanny Schüpfer, Juan Camilo Paredes Escobar, Jeremy Keith Herren
Insects commonly harbor facultative bacterial endosymbionts, such as Wolbachia and Spiroplasma species, that are vertically transmitted from mothers to their offspring. These endosymbiontic bacteria increase their propagation by manipulating host reproduct ...
