Biography                 

I have been working on the full-length synthetic HIV-1 Tat protein for many years and originally performed in 1997 the full structure activity relationship study which highlighted the cationic region of the protein to be responsible for the cellular translocation property. One of the first Cell-Penetrating Peptide was identified. This Tat peptide has been then exploited worldwide for the cellular delivery of hundreds of different molecules (proteins, peptides, nucleic acids, liposomes, nanoparticles…). Later in 2003, I further investigated the mechanism of cell entry of this peptide and discovered that artefactual fixation conditions altered the pattern of the experimental data previously presented for this category of cell-penetrating peptide. Few years ago, I oriented my research in the design of original cancer cell-targeting peptides in order to deliver any devices loaded with drugs or pharmaceutical molecules specifically to the tumour cells. Five years ago, I joined the research group of Prisca Boisguérin, Karidia Konate, Sébastien Deshayes. Based on our respective expertise, we designed with Gudrun Aldrian a large series of new Cell-Penetrating Peptides and we discovered the impressive ability of the WRAP peptides to promote the cellular delivery of various nucleic acid molecules.
