Funding Amount
$554,901.00
Summary
Vitamin B12 is required for red blood cell formation, DNA synthesis and normal neurological function. B12 deficiency contributes to age-related cognitive decline and Alzheimer’s disease. This research will provide important new information regarding the ageing process and the impact that brain changes associated with ageing and Alzheimer's disease have on B12 metabolism. It will provide important information related to the therapeutic potential of B12.
Defining The Mechanisms By Which ABCA7 And ApoE Control Alzheimer's Disease Risk. Functional Characterisation Of New Therapeutic Targets For Dementia Prevention And Treatment.

Summary
Alzheimer’s disease (AD) is the major cause of dementia and is currently without a curative treatment. An understanding of the pathways that lead to AD is urgently required to develop approaches for treatments. We have discovered new pathways by which proteins called ApoE and ABCA7 control AD. We now aim to define precisely how these proteins work in the brain and use this information to develop therapeutic approaches to treat AD in humans.
Is Kainate Receptor Dysfunction At The Core Of Multiple Sclerosis Neuropathology?

Summary
Multiple Sclerosis (MS) is a devastating disease. The current treatments for MS are not able to prevent the death of cells in the brain and are not able to prevent disability in MS patients. I have identified a family of genes that I predict are responsible for cell death in MS. I will determine what these genes do in the brain. My aim is to identify a target for new treatments to prevent cell death in MS.
Interactions Between Developmental NMDA Receptor Dysfunction, Genetic Vulnerability And Early-life Stress In Schizophrenia: Studies Of Dysbindin Mutant Mice And Living Individuals At High Risk Of Schizophrenia
Funder
National Health and Medical Research Council
Funding Amount
$347,457.00
Summary
This project will investigate two key pathways implicated in schizophrenia: glutamatergic (excitatory) neurotransmission and stress signalling. We will study how glutamatergic deficits emerge across postnatal development, in the presence or absence of early-life stress, in a schizophrenia-relevant mouse model, and investigate the interactions between stress and glutamatergic deficits in neuroepithelial cells from living individuals at high risk of schizophrenia.
Novel Pathomechanisms And Treatment Approaches In Alzheimer’s Disease And Related Forms Of Dementia
Funder
National Health and Medical Research Council
Funding Amount
$774,540.00
Summary
This fellowship will provide new insight into the molecular processes underlying onset and progression of common brain conditions, including Alzheimer’s disease, Frontotemporal dementia and Motor Neuron Disease. Furthermore, new therapeutic targets for these diseases will be developed and tested in model systems, to facilitate future translation into clinical application, and to overcome the lack of treatments.
Pathogenesis And Therapeutic Modulation Of Aggressive Behaviour In A Mouse Model Of Autism Spectrum Disorder
Funder
National Health and Medical Research Council
Funding Amount
$583,015.00
Summary
This project focuses on understanding the causes of aggressive behaviour in mice that have a human gene mutation found in autism. Aggressive behaviour is common in autism patients and can have severe consequences on education and employment opportunities. These mice also show excess dampening of brain function (inhibition). This project will test if aggression in these mice is caused by altered inhibition.
Experience-dependent Cellular Plasticity And Cognitive Deficits In Mouse Models Of Schizophrenia

Summary
Schizophrenia is a brain disorder involving psychiatric symptoms which include abnormalities of cognitive processes. We are using mouse models to understand the cause of cognitive deficits, at the level of molecules and cells. One discovery we have made is that the generation of new neurons, from adult neural stem cells, are abnormal in a specific brain region of these mice. This research will provide new information regarding the cause of cognitive deficits, and will have implications for the d ....Schizophrenia is a brain disorder involving psychiatric symptoms which include abnormalities of cognitive processes.
