Stéphanie Pontier was a senior post-doc in the lab from 2010 to 2015. She recently moved to Ottawa (Canada). Stéphanie studied the role of pheromone communication in the regulation of gonad development in the fruit fly. She discovered that female and male flies communicate during development. She also made the striking disovery that the endosymbiotic bacteria Wolbachia manipulate this communication to favor its spreading in the population via an unknown mechanism that eventually regulates gamete compatibility (the so-called Wolbachia-induced cytoplasmic incompatibility).
Stem cells and tissue homeostasis
We have studied together with A. Bardin (Curie Institut) the role of Notch in the regulation of stem cell proliferation and differentiation in the adult fly gut. A. J. Bardin, C. N. Perdigoto, T. […]
Sex, Gamete Compatibility, Pheromones and Endosymbiots
Gamete compatibility is fundamental to sexual reproduction. Wolbachia are maternally inherited endosymbiontic bacteria that manipulate gamete compatibility in many arthropod species. In Drosophila, the fertilization of uninfected eggs by sperm from Wolbachia-infected males often […]
