Epigenetics and genome stability : how the environment affects transposable element stability.

Epigenetics and genome stability : how the environment affects transposable element stability.

We study genome stability through the diversity of the epigenetic pathways controlling TEs, in normal conditions and when the environment changes. We use fresh Drosophila samples coming from temperate (France) and tropical (Brasil) areas, that are submitted to various environmental stress. We then characterize TE content and activity as well as epigenetic regulation using NGS technologies.

Endogenous Retroviruses and Immunity

Endogenous Retroviruses and Immunity

We want to investigate the interplay between the host immune responses to arbovirus (Arthropod Borne virus) infections and the TE and Endogenous Retroviruses (ERV) genomic control mechanisms (RNA interference : piRNA and siRNA pathways) using Drosophila as an in vivo model system. To this end, we will take advantage of the natural variability existing between and within species for ERVs (copy numbers, activities, and control by the piRNA pathway).
