The influence of environmental factors on a mouse model for neuropsychiatric disorders

The development of neuropsychiatric disorders is based on a complex interaction between genetic risk factors as well as pre-, peri-, and postnatal environmental factors. From humans it is well known that a maternal infection during pregnancy elevates the offspring’s risk to progress neuropsychiatric disorders in later life. Although the developmental risk is higher a second negative hit as a catalyst is necessary to manifest the disorder (cp. “two-hit hypothesis of schizophrenia”). Thus, a well established mouse model of viral-like infection is used to mimic the acute phase of a viral infection on pregnant dams (1st hit). They are exposed to either polyI:C or vehicle treatment and the offspring will be kept either in a chronic stress paradigm (2nd hit) or in standard housing conditions. The dissertation project aims at dissecting the contribution of pre- and postnatal environmental factors on the development of schizophrenia-like behavioural deficits, e. g. social behaviour, locomotor response to psycho stimulants or prepulse inhibition. To investigate neuronal correlates underlying these phenotypes further investigations including a) adult neurogenesis, b) the diversity of interneurons as marker for cortical inhibition and c) the myelinisation of nerve cells during neuronal development will be realized.
