Für meine Familie For my family
Acknowledgements First and foremost I would like to thank Prof. Stephan Kröger for giving me the opportunity to perform my PhD Thesis in his laboratory. I want to thank him for his constant supportfor sharing his great knowledge in neuroscience and for sharing his experience on giving a talk. He was always friendly and patient. He was encouraging me, following my project with great interest, discussing with me and guiding me to the right direction whenever necessary. Thank for the relaxing environment in his lab, so that I enjoyed the process on doing research. Thanks to Prof. George Boyan for being my supervisor from the Department of Biology and member of my thesis committee meeting; contributing ideas and copious discussion. Thanks to Dr. Ilona Kadow for being on my thesis committee, and being an excellent example, doing science with kids, this encouraged me a lot. I would also like to thank Prof. Magdalena Götz and the Graduate School HELENA at the Helmholtz Centre for funding my PhD and allowing me to take part in conferences. I am truly grateful to Dr. Shuo Lin and Prof. Markus Rüegg for the kind collaboration and breeding agrin knockout mice for me. Thanks to Prof. Veit Witzemann for nice discussions, both scientifically and non- scientifically and for providing transgenic mice. Thanks to Prof. Martin Kerschenstener for providing Thy1-YFP 16 mouse line. I would also thank to Monica, Michele, Miriam, Yvonne and all colleagues in our THS44 animal faculty, for taking care of my mice. Thanks to Dr. Ahmed Messoudi and Dr. Anja Bochtler for the great collaboration and discussion and thanks to Dr. Lydia Sorokin, Dr. Wilko Altrock, Prof. Rüdiger Rudolf and Prof. Claire Legay for sharing antibodies. I want to thank Katja Peters for excellent technical support, moreover, for improving my German. I would also like to thank Ines Mühlhahn for helping me in CsCl DNA preparation, in using devices with her excellent guidance. Great thank to Lana Polero, Elsa Melo and Suada Ajanovic for taking care all the small things, which are actually very important, such as contract extension, registration for business trip etc.
I am truly glad to have had a lot of great scientific discussions with Alex Pevzner, Julia Meltoranta, Andormachi Karakatsani, Anna Schick, Christiane Gasperi, Vivian Westermayer, Marta Wesolowski, Rebeca Sadler and Sarah Feldkirchner. Thank you for all the lab girls, for the nice time we spend together, thank you for your encouragement, your care and your smile. Thanks to Julia for professional photo shootings, thank Christiane for sharing wonderful classic music, thank Alex, Katja and Marta to have so much fun in the lab, thanks to Becky to correct my English, thank all of you, lovely girls. Special thanks to my companion in arms ---- Andromachi, we spend most time together, complaining to each other, encouraging each other, discussing with each other, now we are almost reach the destination, just persisting the last distance. Of course, I also want to thank my friends in the neighbour lab, Sergio Gascon, Felipe Ortega de la O, Francesca Vigano, Aditi Deshpande, Sophia Bardehle, Elisa Murenu and Sofia Grade. Thanks for sharing your opinions, for discussion, for chatting, for all the time we spent together. Lastly, I want to thank the most important people in my life: thanks to my husband, Jun Li for always believing in me, encouraging me and for his constant support. Thank you for giving me our lovely daughter! Thank my daughter, Feiya to forgive me away from her for so many hours every day. I am most thankful to my parents and parents in law. It is you, my mother and my mother in law, who was travelling from China at least 24 hours to Munich every six months and stayed with me for three month alternately. You were not only taking care of my child, but also taking care of me, so that I could be concentrated in my PhD thesis. Without you, I would not have managed to complete my PhD. Thank all of you so much!!! Yina Zhang
