In first place, I would like to thank the members of the jury that have kindly accepted to evaluate my work: Pr. Knebelmann, Pr Waltz, Pr Knebelman, Pr Salomon. A special thank goes to Mme Lelongt and M Cohen-Tannoudji to have reviewed my thesis and to give very useful suggestions in order to ameliorate it. A long journey needs good leading. For the precious and irreplaceable help and support I would like to thank Marco and Evelyne that overviewed all my work (and corrected the not- so-few mistakes I did on the way). They avoid me to get lost in failing experiments and frustrating periods, as well as to encourage my enthusiasm. I’m still in love with the research! Once the journey has started, I found a very important help from the entire group of colleagues: the “Pontoglio’s team” crew always supported me and offered me the pratical/technical/moral support to achieve my work. I would like to thank the actual members of the lab (Serge, Michel, Magali, Jon, Cecile and Claire) and the people I have the pleasure to meet in the lab and that are now in the different corner of the world (the spanish Miguel and Kiko, Celine and Tristan). A big thank to all the friends that I meet during my thesis: too many to number them without forgiving someone… Thanks for the support you gave me, for the antibodies protocols and suggestion you gave me, without forgetting the long nights spent partying around! In conclusion, useless to check the list of the names, I could not double the size of my thesis!! But I will remember all of you wherever I will go Of course, a very special thank goes to my parents Ezio and Grazia that supported me (even with excellent food supplies) all along my thesis and to my brothers Corrado and Emanuele! Thanks also to Giulia and Veronica to support and stand my bros, and without forgetting the newcomer Edoardo. Finally, THE very special thanks to Eva that stand me all along the way and gave me the strength to keep going on, even if sometimes the things seem not to work and I was tempted to give up.
