Laura Ciapponi, Principal Investigator

I received my Ph.D. in Genetics and Molecular Biology at the Research Institute of Molecular Biology Laboratory (IRBM) and the Sapienza University of Rome, for my work on the IL-6 receptor complex properties in the laboratory of Gennaro Ciliberto. Then, I left for Germany, where I performed my postdoctoral studies at the European Molecular Biology Laboratory (EMBL), in the laboratory of Dirk Bohmann, moving to the Drosophila melanogaster model system, that will be the landmark for my entire future scientific carrier. I used Drosophila first for studying the mechanisms of differential activation of AP1 transcription factors by the JNK or MAPK pathways and, more recently, for the understanding of the crosstalk between DNA repair, telomeres protection and maintenance of mitotic chromosome stability. Lately, I am using Drosophila as model system for studying neurodegenerative diseases and, in particular, for the dissection of the pathogenic mechanisms of the Myotonic Dystrophy of type 2 (DM2), of the human primary microcephaly (MCPH) and of the Amyotrophic Lateral Sclerosis (ALS).
