Page | 5 Agathe Franck – phD thesis 2018 “On endocytic proteins in muscle” Acknowledgements First of all, I would like to thank Stéphane Vassilopoulos, my thesis supervisor. As I said, I’m not very good at this. Thank you for giving me a chance all these years ago, after reading the letter of a small master 1 student that just “wanted to do microscopy”. Thank you for the pep talks, the laughs, the evenings with Jeanne at the electron microscope, open mouthed in front of her beautiful pictures, the late lunches at the Japanese place near Jussieu, the pride I felt when I showed you my pictures, thank you for believing me, for your passion about our work, for maneuvering my boat through these years that have not always been easy… in short, thank you for everything. I’m also very grateful to Marc Bitoun, our great chief and leader. Thank you for your help, for always being caring and patient. Thank you also for your advices and very (very) pertinent questions. Jeanne, thank you forever for giving me the beautiful pictures that I included in this thesis manuscript. Thank you for your kindness and always being there when I needed to talk (most of the people I know think you are my shrink). You’ve helped me stay afloat and I will forever be grateful. How could I not thank lab 103. This melting pot of characters and personalities. Anaïs Fongy, Éline Lemerle, Corine, Margot, Bernard and Camilla. Sometimes we work there, but we also laugh. A lot. I’d like to thank especially Anaïs, who has helped me believe in myself at a time when no one could achieve it. Éline, I wish you all the best for the future, you can always call me. Anytime. I will also thank the expat members of team 2, Delphine and Gilles, and the one who is even further away, Bruno Cadot. I’m especially grateful to Gilles for the precious help and guidance since his arrival, and I am truly sorry for all the unlucky PCRs my cells have caused. Valérie Allamand, thank you for your reassuring presence in the lab, during evenings, during the weekends, thank you for your smile and for listening, and also… thank you for the milk! The YAP/TAZ part of this project could not have been realized without the help and expertise of Catherine Coirault. Thank you for the Flexcell and the various talks about YAP/TAZ shuttling, without you we would have been lost. This work was completed thanks to the receptiveness of the imaging platforms. A big thank you to the Cytometry and Imaging Platform of Gustave Roussy Institute, particularly to Corinne Laplace-Builhé and Sophie Salomé-Desnoulez. Thank you also to the imaging platforms of the Institut de Biologie Paris-Seine, Michaël Trichet for his enormous help in making metal replicas of our samples possible, and Susanne Bolte, Jean-François Gilles and France Lam for their expertise in fluorescence microscopy. I am also grateful to the Pitié-Salpêtrière cell imaging platform staff who often asked me if I wanted a bed installed next to their microscope. This work also relied on the biopsies given by patients affected by centronuclear myopathy or desminopathies. We are grateful to Muscle Tissue Culture Collection MTCC at Klinikum der Universität München for providing the p.R350P primary cells, and to Anne and Kamel of the Myology Institute’s immortalization platform for the immortalization of these cells and CNM patients’ myoblasts. I thank the Morphological Unit, especially Norma Romero, Michel Fardeau, Emmanuelle Lacène, Mai Thao Viou and Guy Brochier, for their precious help regarding the characterization of desmin anomalies in patients affected by AD CNM. Thanks also to Laura Julien of the vectorology platform regarding the production of the AAV used in this study. Pr. Onnik Agbulut, thank you for your smile, and for the precious help to this study by giving us desmin -/- mice. Page | 6 I am grateful to the members of thesis committee who have followed me through these years: Stéphanie Miserey-Lenkei, Guillaume Montagnac and Denis Furling. Stéphanie, I will not forget your precious advice. Marie-Claude Potier, thank you for your support, I carry a bit of the expertise acquired in your lab everywhere I go. I am grateful to the committee attributing doctoral contracts for believing in my project. I cannot end without thanking all the people who have carried me to hell and back: my mom, Mallory, Lucile, Emmanuelle, Georges, Clément and Guilhem Salines, Ronan, Aless, Sophie, the Gründ team, my favorite cousin Émilie, Alice, Julie, Gertrude, Florent, Capucine, Romain, Ségolène… This will seem strange but I’d like to thank my cat. He’ll understand. I owe more than a « thank you » to a person named Lola Salines. Lola, this work is dedicated to you, and I would like to write, as an opening to this thesis manuscript, all my gratitude, and all my love.
