The brain exerts a restraining influence over the heartbeat via the vagus nerves. This is known as cardiac vagal ‘tone’. It is strong when we are healthy but weak when we are sick. It has a positive influence on the health of the heart and perhaps the body generally. Vagal tone comes from the brain but, despite over 150 years’ research, nobody knows exactly where. Using a novel technique, we can track down its origins. This important basic knowledge may lead to ways to improve health.
Radiosensitisation Of Diffuse Intrinsic Pontine Gliomas By Modulating Glucose Metabolism
Funder

Funding Amount
$325,000.00
Summary
Diffuse intrinsic pontine glioma (DIPG) represents the most aggressive cancer of childhood with no effective treatment available and radiotherapy is the only form of treatment that offers a transient benefit. We have successfully grown the first DIPG cells in the laboratory and found a new approach to radiosensitise them by targeting glucose metabolism. We will build on these findings and develop this treatment strategy to make this novel therapy available to children with this deadly disease.
Targeting Mitochondrial Metabolism In Diffuse Intrinsic Pontine Gliomas As A Novel Therapeutic Strategy

Summary
Diffuse Intrinsic Pontine Glioma (DIPG) represents the most aggressive cancer of childhood, with no effective treatments available, and almost all children dying within one year of diagnosis. We have successfully grown the first DIPG cells in the laboratory and found a new approach to attack them, by specifically targeting the cell's power source - the mitochondria. We will build on these findings and develop this treatment strategy with the aim to make this novel therapy available to children w ....Diffuse Intrinsic Pontine Glioma (DIPG) represents the most aggressive cancer of childhood, with no effective treatments available, and almost all children dying within one year of diagnosis.

A 3D Cross-Modality Atlas Of The Human Brainstem For Scientists And Clinicians

Funding Amount
$363,455.00
Summary
Recent technical advances dramatically improved imaging of the human brainstem. However, there are limited frameworks for interpreting the images. The project will address this by acquiring high quality MRI anatomical and MR microscopy data from postmortem brains and registering these with structures in Atlas of the Human Brainstem (Paxinos and Huang, 1995) where almost 500 brain areas are delineated. Our work will assist with the diagnosis of brain disorders and facilitate clinical research.
Brainstem And Hypothalamic Function And Anatomy In Migraine

Funding Amount
$652,828.00
Summary
Migraine is a disabling condition characterized by mostly unilateral throbbing head pain and a range of associated neurological symptoms. The underlying mechanisms responsible for the initiation of migraine remains unknown. We aim to determine brain anatomy and activity patterns in migraineurs throughout the migraine cycle. An understanding of the mechanisms responsible for migraine will aid in better treatment development.
PACAP: The Mechanism Underlying Sleep Apnoea-induced Hypertension

Funding Amount
$505,117.00
Summary
10% of Australians suffer from sleep apnoea; a cause of high blood pressure. Untreated, high blood pressure causes heart failure, kidney failure and stroke. A major cause of high blood pressure is an increased amount of nerve activity that controls the heart and blood vessels. In this proposal we will investigate how a brain chemical, called PACAP, affects nerve activity and blood pressure in a model of sleep apnoea. This information may lead to new and better treatments for high blood pressure.
Reduction Of The Cardiovascular Response Of Psychological Stress Through Blockade Of Orexin’s Action On One Of Its Receptors.

Funding Amount
$394,925.00
Summary
Anxiety, fear of challenges, frustration are part of modern life stressors. Our body reacts to these stressors by increasing blood pressure and heart rate, which in turn can harm our cardiovascular system and precipitate cardiovascular accidents. In this project we test a new class of drugs that act on a neurochemical system implicated in these particular responses. If our hypothesis is correct, one of these drugs could be used to relax the cardiovascular system and protect it in times of stress ....Anxiety, fear of challenges, frustration are part of modern life stressors.

Cancer Anorexia/cachexia: Mechanisms For Anorexia And Appetite Regulation By Tumour Derived MIC-1/GDF15

Funding Amount
$643,060.00
Summary
We have recently discovered that MIC-1 is a new appetite suppressive agent which when overproduced in some diseases like cancer, causes severe weight loss. This project sets out to determine the mechanisms it employs in regulation of appetite centres in the brain.
