Research Theme: Phenotyping of murine mutant models of human disease


Keywords: mouse mutant, disease models, cerebellum, primary cilium, medulloblastoma

During my graduation thesis and PhD work I had the opportunity to learn the basics of cellular and molecular biology in mouse model systems, with particular attention to the early stages of embryonic development and transcription activation mechanisms. In the last decade, I have been working on the production and functional characterization of novel mouse mutant models of brain development and related disorders. In particular, I studied the role of Gpr37L1, an orphan G-protein coupled receptor, which specifically modulates cerebellar cell proliferation and differentiation, with an emphasis to the role of the primary cilium in the regulation of cell proliferation in physiological and pathological conditions. Recently I also had the opportunity to deepen my knowledge of confocal microscopy and analysis of images acquired with post-processing programs.

In addition, I have been participating in the histopathology screening pipelines of the International Mouse Phenotyping Consortium (IMPC;, the INFRAFRONTIER European Union’s Landmark Infrastructure ( and related International Consortia (EUMORPHIA, EUMODIC, EUCOMM-EUCOMMTools, PHENOSCALE, etc.), for large-scale, integrated and standardized production, primary and specialized phenotyping, dissemination of mouse mutant strains as novel in vivo model of human diseases.
