Immediate Cooling And Emergency Decompression (ICED) For The Treatment Of Spinal Cord Injury: Pilot, Safety And Feasibility Studies
Funder

Funding Amount
$600,008.00
Summary
Victims of Spinal Cord Injury are young, have severe paralysis, complex needs and high lifetime costs. Although urgent surgery greatly improves outcome, it is difficult to achieve because of logistical difficulties. To expand the time window for early surgery, it is proposed to immediately cool patients. This project will conduct the pilot studies necessary before commencing a clinical trial of immediate cooling and emergency decompression (ICED) in patients with cervical spinal cord injuries.
Effectiveness Of Ghrelin Receptor Agonists To Limit The Extent Of Tissue Damage Caused By Traumatic Injury To The Central Nervous System

Funding Amount
$592,002.00
Summary
Ghrelin is a naturally occurring compound that under adverse conditions can activate specific receptors on cells around the body to enhance their survival. These receptors are also present in the spinal cord, but ghrelin doesn't enter the spinal cord. We will investigate a new group of compounds that can enter the spinal cord and activate these receptors to see if this can reduce the amount of damage that occurs after a spinal cord injury. Less tissue damage would mean less permanent disability.
Targeting The Complement Activation Fragment C5a To Improve The Outcome From Spinal Cord Injury

Funding Amount
$406,838.00
Summary
This project will focus on the development of a new drug that is designed to attenuate the harmful inflammatory response that follows from spinal cord injury (SCI). The experiments will determine if the therapeutic targeting of an immune receptor molecule, called C5aR, can protect compromised neural tissues after injury against harmful inflammation and degeneration whilst also explore the mechanism behind the therapeutic effect.
Hypothermia Prior To Decompression For Treatment Of Acute Spinal Cord Injury

Funding Amount
$294,163.00
Summary
In spinal cord injuries, the cord is compressed as a result of vertebral injury. Urgent relief of compression improves outcome, however, is difficult because of the complexity of pre-surgical management. Our data demonstrate that hypothermia stops compressive spinal cord injury, allowing decompression to be performed in a period that will benefit most patients. This project aims to undertake the studies necessary before beginning a human trial of hypothermia prior to decompressive surgery.
Can Exercise Early After Spinal Cord Injury Prevent Deterioration Of Muscle And Bone?

Funding Amount
$775,049.00
Summary
Spinal cord injury leads to a profound deterioration of the muscles and bones in the paralysed limbs. This project will examine the effects of exercising the paralysed limbs as early as possible after injury to prevent muscle and bone loss rather than restoring the tissues once changes have occurred. The time course and mechanisms underlying the microstructural decay of bone over the first year after injury will also be examined to provide a basis for determining fracture risk in this group.
The Role Of Presynaptic Inhibition In Neuropathic Pain

Funding Amount
$466,045.00
Summary
Inhibitory nerve cells in the spinal cord are thought to play an important role in governing the interaction between painful and non-painful stimuli. Defects in this process underlie allodynia, an important symptom of neuropathic pain. We will use recent advances in genetic techniques (optogenetics) to manipulate and study how inhibitory nerve cells separate touch and pain signalling in the spinal cord of normal and neuropathic animals.
Identifying Novel Molecular Targets For Treating Chronic Pain.

Funding Amount
$402,952.00
Summary
Chronic pain is very common, with one in five Australians suffering long-term pain that is serious enough to cause disability. It is extraordinarily difficult to treat. Medicines used to treat normal pain symptoms are usually ineffective on chronic pain patients because the cause of the pain is different. The aim of this project is to identify new drug targets in the spinal cord that are specific for chronic pain so we can develop new medicines to reverse the symptoms safely and effectively.
Excitatory Interneurons: A Sensory Amplifier For Pathological Pain
Funder
National Health and Medical Research Council
Funding Amount
$649,848.00
Summary
Changes to the nervous system during pathological pain remain poorly understood. This poses a barrier to new and more effective pain therapies. We have recently shown that a population of excitatory nerve cells, which express a protein called calretinin, form an amplifier network within the spinal cord that enhances pain signalling. This application will determine how calretinin-positive nerve cells contribute to pathological pain and can subsequently be targeted to provide pain relief.
CSF Physiology: Flow In The Spinal Cord And Subarachnoid Space

Funding Amount
$375,775.00
Summary
Fluid flow in the brain and spinal cord is important in health and disease. Increased fluid leads to hydrocephalus and spinal cord cysts. Impaired flow through the brain and cord contributes to Alzheimer's disease and other disorders. How fluid flows through the brain and spinal cord is poorly understood. We will study important aspects of flow in the spinal cord and how flow is affected by obstructions in the fluid pathways.
Why Macrophages Promote Heterotopic Ossifications Following Spinal Cord Injuries
Funder

Funding Amount
$586,950.00
Summary
A frequent complications of brain and spine injuries is the formation of bones outside of the skeleton called "heterotopic ossifications", particularly around joints such as the knee, hip, elbow or shoulder. They grow over a few months to become so large (up to 2 kg) that they block muscles and joints, increasing pain, morbidity and dependance. This project is to understand why heterotopic ossifications form in patients with spine injuries aiming to discover effecttive treatments.
