Nerve cell survival is dependent on both growth-promoting factors and factors released by neurotransmission, which can promote recovery in neurodegenerative conditions by overriding cell death pathways. The molecule responsible for activating death pathways in the nervous system is called p75. This project will investigate how p75 results in cell death, how synaptic signals can prevent the activation of the p75 death pathway and whether blocking p75 function can limit neurodegeneration.
Studying The Two Hit Hypothesis Of Psychiatric Illness: Role Of Brain-derived Neurotrophic Factor (BDNF)

Summary
Psychiatric illnesses such as schizophrenia and depression are caused by at least two major disrupting events in development: one during early brain development and one during-after puberty. We will use animal models of schizophrenia, induced by administering stressors such as maternal separation, corticosterone or cannabinoid treatment at different stages of their lives. These animal models will be used to further investigate antipsychotic treatment therapies

Summary
Schizophrenia is characterized by psychosis, social and occupational dysfunction and cognitive deficits. Males are more often diagnosed and more severely impaired than females. Onset in males is most frequent during adolescence, a time of increasing sex hormones. We ask, how do sex hormones act on the adolescent male brain to impact the onset and symptoms of schizophrenia? The answer will allow development of gender and age-specific interventions to prevent onset or ameliorate symptoms.

Summary
Demyelinating diseases of the central nervous system such as multiple sclerosis have a lifelong impact and devastating impact on quality of life. We have identified that a growth factor, brain derived neurotrophic factor (BDNF), plays an important role in promoting myelination during development. We will investigate the potential of translating these findings into effective clinical treatment, by characterising the efficacy of BDNF in promoting CNS remyelination after a demyelinating insult.
