Targeting Central Inflammation To Combat Obesity And Obesity-related Cognitive Dysfunction

Funding Amount
$470,144.00
Summary
The current obesity epidemic means many of us will suffer from overweight or obesity for at least some of our lives. My findings show obesity can cause inflammation throughout the brain including in regions related to learning and memory. Here I hypothesize that obesity induces long-term changes in the brain’s immune cells, that this can explain why we see susceptibility to cognitive decline in obese individuals, and that we can reverse these negative effects by targeting these immune cells.
Long-term Physical Exercise Improves Cognitive Performance Through Neuroimmune Modulation
Funder
National Health and Medical Research Council
Funding Amount
$493,586.00
Summary
This research investigates for how long exercise needs to carried out in order to be beneficial for cognitive function. We choose an animal model which simulates chronic brain inflammation as seen during aging processes of humans and during many inflammatory diseases affecting brain function. This research will unravel the long-term immunomodulatory and protective effects of exercise on brain function as well as the short-term anti-inflammatory effects on brain function.
Defining The Role Of Inflammation In Depression During Aging

Funding Amount
$736,820.00
Summary
This proposed research investigates the bidirectional relationship between inflammation in the central nervous system (CNS) and depression during normal aging processes. It is assumed that inflammatory processes in the CNS will induce the development of depression and vice versa, that depression will lead to increased inflammation in the body. In addition, the research will study the genetic background and gene expression of inflammation contributing to both aging processes and the onset of depr ....This proposed research investigates the bidirectional relationship between inflammation in the central nervous system (CNS) and depression during normal aging processes.

The Role Of Metals In Healthy Brain Aging: Identification Of Novel Compounds To Prevent Age-related Cognitive Decline
Funder
National Health and Medical Research Council
Funding Amount
$789,733.00
Summary
This grant will explore the basic mechanisms that underlie normal learning and memory. Specifically, we are focussing on how the modulation of metal levels may occur with age, and how this may cause or at least contribute to age-related cognitive impairment. We are also examining a novel therapeutic compound for the treatment of cognitive dysfunction. This work will have implications for both normal and pathological ageing.
‘Chemobrain’: Neuroimmunological Consequences Of Chemotherapy-induced Mucositis And Opioid Palliation In Development Of The Condition
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
Approximately 46% of cancer patients receiving chemotherapy will experience cognitive impairment. The development of this condition may be linked to another common gut side-effect of chemotherapy- mucositis. The treatment of mucositis pain by potent painkillers called opioids may also increase the risk of cognitive change. This project will determine the nervous system changes occurring in mucositis to identify targets for drug intervention to prevent development of cognitive decline.
Electrical Stimulation With A “Random Noise” Pattern: A New Approach For The Treatment Of Depression
Funder
National Health and Medical Research Council
Funding Amount
$523,160.00
Summary
This study is a world first, examining the use of a novel technology to treat depression by stimulating the brain mildly and non invasively. The study will examine the effectiveness of a 4-week course of Transcranial “Random Noise” Stimulation to treat depression, and will also measure whether improvement in mood is accompanied by a restoration of brain plasticity or adaptability.
Inflammation plays both protective and damaging roles in Alzheimer’s disease (AD), so to identify a long lasting and effective treatment, it is important that we better understand the underlying processes. Our studies implicate a cytokine called interleukin-18 (IL-18) as a factor that accelerates AD pathology. Here we propose to study the mechanisms by which this cytokine alters basic cell biological functions and how these changes affect AD pathogenesis.
Biomaterials For The Direct Reprograming Of Reactive Astrocytes Into Functional Neurons
Funder
National Health and Medical Research Council
Funding Amount
$630,500.00
Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.
Molecular Imaging To Advance Treatment Of Dementia
Funder
National Health and Medical Research Council
Funding Amount
$412,419.00
Summary
Molecular imaging using a scan technique called positron emission tomography, enables detection and measurement of specific pathological features of disease such as the amyloid plaques of Alzheimer’s disease. This project will develop this technology for other aspects of brain disorders including dementias, Parkinson’s disease, traumatic brain injury and schizophrenia and use it to assist development of therapies and improve clinical diagnosis nation wide.
