Nodal Function In Peripheral Neuroinflammatory Disorders: Target Antigens, Functional Significance And Treatment Response

Funding Amount

Summary
Inflammatory neuropathies are autoimmune disorders which produce severe disability and represent a costly burden to the healthcare system, but the causes remain unknown. Recent evidence from our team suggests that antibodies against parts of the peripheral nerve at the node of Ranvier are involved. The project aims to identify these specific targets and monitor treatment responsiveness, stabilise nerve function and prevent persistent disability.
Prevention Of Beta Cell Destruction In Type 1 Diabetes By Immunotherapy Using Parasite-derived Molecules.

Summary
To prevent type 1 diabetes, compounds that avert the autoimmune destruction of beta cells are needed. We are exploiting the potential of ñworm therapyî by mimicking the beneficial immune effects of parasite worm infection. We have identified the molecules that the parasite uses to influence host immune responses. We have demonstrated that these novel immune-modulatory worm molecules prevent diabetes in a mouse model. This offers great potential for the development of therapeutic interventions.
Neuronal Substrate Of Choice In The Rat Whisker System

Funding Amount
$405,851.00
Summary
Humans and other animals can optimise their goal-directed behaviour by linking stimuli or actions to consequent positive and negative rewards. How does an animal generate such associations, and make decisions in the natural environment where the associations are often uncertain, at times contradictory, and continuously changing? This project uses rat whisker system as an animal model to identify the neuronal basis of perceptual decision making and the role of context.
THE EFFECT OF STRESS AND ENVIRONMENTAL ENRICHMENT ON DISEASE PROGRESSION IN MESIAL TEMPORAL LOBE EPILEPSY
Funder

Funding Amount
$578,201.00
Summary
Mesial temporal lobe epilepsy, the most common form of drug-resistant epilepsy in adults, is a progressive neurodegenerative condition for which there is currently no effective disease modifying treatment. This proposal will explore whether co-morbid stress accelerates disease progression in MTLE, and whether targeting stress pathways by medical and environmental manipulations can mitigate against this.
A Multi-national Trial To Predict Treatment Response In Subtypes Of Depression
Funder
National Health and Medical Research Council
Funding Amount
$387,489.00
Summary
Treatment of MDD using trial and error can have serious consequences. It can prolong the patient’s suffering (depression is associated with substantial morbidity, and mortality), prolong their absence from work and other productive activity and increase the burden on their family-carers. This multi-national study will collect genetics, brain function and behavioural data from a large number of participants, allowing for sensitive predictors of response to be determined.
Predictors Of Response To Antidepressants: Utility Of Behavioural, Neuroimaging And Genetics Data

Summary
Major depressive disorder (MDD) is projected to cause the second greatest global burden of disease by 2020, highlighting the urgent need for valid predictors of effective treatment response. Currently, there are no accurate predictors of response to antidepressants in MDD, and successful treatment relies greatly on 'trial and error'. This process is demanding on health resources, and may be a factor in the high suicide rates in depressed patients. Previous research on treatment response has been ....Major depressive disorder (MDD) is projected to cause the second greatest global burden of disease by 2020, highlighting the urgent need for valid predictors of effective treatment response. Currently, there are no accurate predictors of response to antidepressants in MDD, and successful treatment relies greatly on 'trial and error'. This process is demanding on health resources, and may be a factor in the high suicide rates in depressed patients. Previous research on treatment response has been limited by recruitment of small, heterogeneous patient samples, lack of placebo control, and a failure to examine task related activity in brain imaging studies. Perhaps one of the more troubling aspects of research that aims to predict treatment response to antidepressant medications is the use of commonly used outcome measures such as the Hamilton Rating Depression Scale (HAM-D), which were developed long before current classification systems of depression came into use. The US Federal Drug Administration has recently identified what they call a translational gap such that behavioural and biological measures are the most robust for detection of disorders such as depression, yet these measures remain to be translated into clinical tools that can be used to evaluate treatment. The aim of the current study therefore is to determine whether genetic variability is related to treatment outcome as defined by a more objective outcome measure (facial expression perception) using a randomised controlled design. The study will also determine whether brain measures (fMRI, EEG) enhance the prediction of SSRI response to both clinical and behavioural measures, over and above the genetic contribution.Read moreRead less
The Role Of Corticothalamic Feedback On The Response Dynamics Of Thalamic Neurons

Funding Amount

Summary
A fundamental question in neuroscience is how the brain selectively processes sensory information to generate a reliable representation of the world. Positioned in the centre of the brain, the thalamus plays a key role in sensory processing. This project investigates how the interaction between thalamus and cortex shapes the selection and gating of sensory information. This is a fundamental question in basic neuroscience with the potential to increase our knowledge about attentional deficits.
Microeconomic effects of Australian natural disasters. This project aims to describe and identify the effects of Australian natural disasters – such as the Black Saturday bushfires and the Brisbane floods – on important microeconomic outcomes, including health, education and employment. Natural disasters have profound economic and social effects on individuals and communities. This project intends to bring evidence on how disasters affect individuals and how the effects can be lessened. The proj ....Microeconomic effects of Australian natural disasters. This project aims to describe and identify the effects of Australian natural disasters – such as the Black Saturday bushfires and the Brisbane floods – on important microeconomic outcomes, including health, education and employment. Natural disasters have profound economic and social effects on individuals and communities. This project intends to bring evidence on how disasters affect individuals and how the effects can be lessened. The project expects to inform policy-makers on these critical issues by analysing field, survey and administrative data on individuals before and after past disasters.Read moreRead less
