Stroke Induced Disturbances In Glymphatic Clearance: Implications For Brain Repair?
Funder

Funding Amount
$491,688.00
Summary
We have made a remarkable discovery that the ability of the brain to clear waste proteins is significantly impaired after stroke. This may have important implications for development of dementia and milder changes in thinking late after stroke. We already have some clues regarding potential mechanisms. In this project we will further investigate these mechanisms and their effects on the brain and develop our understanding of potential ways to reverse the clearance problem to develop treatments.
Microglial Paralysis In Post-stroke Neurodegeneration: Help Or Hindrance?
Funder
National Health and Medical Research Council
Funding Amount
$512,351.00
Summary
Dementia and cognitive decline may occur months or years after a stroke, associated with delayed loss of brain cells in different brain regions. We recently discovered that the cells responsible for protection and repair of brain, called microglia, become paralysed in these regions. We will use a live-imaging microscope to determine whether the microglial paralysis causes brain cell death. We will also determine if a commonly used stroke prevention drug can worsen the microglial paralysis.
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

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.
Lysosomal Dysfunction As An Inhibitor Of Vitamin B12 Utilisation In Neurodegenerative Diseases
Funder

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.

Funding Amount
$687,975.00
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.
Targeting Post-synaptic Tau To Treat Alzheimer's Disease

Funding Amount
$1,686,311.00
Summary
We have previously identified post-synaptic tau as being critical in mediating toxicity in Alzheimer's disease brains. This project aims at understanding the exact underlying molecular mechanisms and, more importantly, developing novel drugs to block early toxicity that initiates cascades that eventually lead to brain atrophy and dementia. To achieve this aim, this project will generate and utilize models of Alzheimer's disease in combination with a broad range of latest analytical tools.
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.
