The main goal of this study was to analyse genetic factors and pathway involved in depressive disorders using mice as animal models. I inactivated FGFR2 in the entire CNS from day 11.5 of embryonic development in mice and my histological analysis revealed cerebellar malformations. I could show that these cerebellar phenotypes are due to developmental defects, probably caused by abnormal Bergmann glia development and morphology. Furthermore, I showed that the restricted inactivation of FGFR2 in forebrain neurons in adult mice altered depression-like behaviour and the acute response to the antidepressant fluoxetine in the forced swim test. Thus, FGFR2 could play a causative role in depressive disorders and mediate behavioural effects of antidepressants. Additionally, I applied the RNAi technique to generate P2RX7 “knockdown” mice as a new model for Depression.
