Structure And Functional Characterisation Of AB5 Toxins

Funding Amount
$574,890.00
Summary
The proposed research program, using a combination of structure and biochemical analyses, will provide insight into two novel AB5 toxins that represent a medically important family of proteins. This study will not only improve our fundamental understanding of AB5 toxins action but could lead to rational design of antimicrobials.
Genetic Validation Of Stat3 As A Tractable Pharmacological Target In Gastrointestinal Disease

Summary
Cancers of the stomach and the colon are a major health burden. One of the central signaling molecules that drives these cancers is called Stat3. Here we propose to use a novel strain of mice that allows us to experimentally dial down the amount of Stat3 protein and hence to predict how effective a future anti-Stat3 cancer drug will be.
Improving Clinical Translation In Stroke: Targeting Cerebral Oedema In A Large Animal Model

Funding Amount

Summary
A common and life-threatening complication of stroke is brain swelling which is the leading cause of death within one week of stroke and a predictor of poor outcome. Current treatments for brain swelling are inadequate. We have developed a drug that blocks the action of the neuropeptide substance P, which is involved in the development of swelling. We will assess the efficacy of this treatment to reduce brain swelling and improve long-term outcome in a relevant pre-clinical model of stroke.
Restoration Of Cognitive Deficits Induced By Diabetes Through The Modulation Of Cerebrovascular Integrity

Summary
Diabetes is a known risk factor for the development of dementia. However the details of this association have not been known. Recent evidence consistently shows that the integrity of blood vessels in the brain may be central to the onset of dementia, and consistently, damaged brain blood vessels are often reported in diabetic patients and animal models. This project is the first to target in restoring the integrity of those brain blood vessels in order to reverse diabetes-associated dementia.
The Involvement Of The Kynurenine Pathway In Blood Brain Barrier Disruption And Its Relevance For Neuroinflammatory Diseases
Funder

Funding Amount
$597,797.00
Summary
We aim to study the involvement of molecules deriving from the degradation of the essential amino acid tryptophan on the breakdown of the ñblood-brain barrierî (the cellular wall separating blood and brain) that is observed in several major brain diseases. Using specific drugs blocking the production or the effects of these toxic compounds we expect to be able to preserve the integrity of the blood brain barrier and so to limit brain inflammation and neuronal loss.
Identification Of Factors Critical For Maintenance Of The Epidermal Barrier

Funding Amount
$616,950.00
Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is the key structural component of the skin barrier and is essential for its integrity. We have identified a family of genes that are pivotal for epidermal barrier formation, maintenance and repair. This project examines the mechanisms that underpin the function of this family, and has broad ramifications in a host of dermatological conditions.

Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is essential for formation and repair of the skin barrier. We have identified a family of genes that are pivotal for skin development and function. Disruption of these genes has disastrous consequences, including loss of barrier function and the development of skin cancers. This project examines how these diseases occur.
Targeted Delivery Of CD39 To Ischaemic Brain Improves Outcomes In Stroke

Funding Amount
$895,780.00
Summary
Stroke is most likely caused by a clot in one of the large blood vessels supplying the brain. The approach is to save the 'at-risk' area of brain with drugs that break-down clots and by manual removal of clots. These treatments are limited by timely access within 4.5 hours to larger hospitals. We are trialing a new drug that protects the brain better on its own and may add to the benefit of current treatments. Moreover, it can be given in any rural setting.
The Effect Of Anti-fibrinolytic Drugs On Blood-brain Barrier Integrity And The Immune Response In Traumatic Brain Injury
Funder

Funding Amount
$870,476.00
Summary
This project aims to determine how a well known anti-fibrinolytic drug can improve the immune response and reduced blood brain barrier disruption following traumatic brain injury. We will also be testing additional drugs we have developed as well as a novel drug delivery system that better targets drugs to the damaged brain.
Blood-Brain Barrier Penetrating Antisense Therapy For Spinal Muscular Atrophy
Funder
National Health and Medical Research Council
Funding Amount
$635,005.00
Summary
Spinal muscular atrophy (SMA) is a genetic disease caused by the deficiency of a protein known as survival motor neuron.This results in the degeneration of motor neurons (nerve cells controlling muscles) leading to progressive muscle weakness, paralysis, and eventual death. Currently, there is no known cure for SMA. The aim of proposed research is to develop gene-modifying molecules that prevent degeneration of motor neuron and extend the life-span of mice as a potential therapy for SMA.
