B Cells And Autoantibodies In The Pathogenesis Of Hypertension
Funder

Funding Amount
$853,340.00
Summary
This project aims to gain a better understanding of the causes of hypertension. Specifically, we will test the idea that activation of the immune system and the production of antibodies is a major cause of the blood vessel and kidney damage that leads to high blood pressure. Such findings could pave the way for new treatment approaches where drugs currently reserved for patients with autoimmune diseases (e.g. rheumatoid arthritis, gout) are re-purposed for the treatment of hypertension.
M2 Macrophage Polarization As A Cause Of Vascular Fibrosis And Stiffening In Hypertension

Funding Amount

Summary
Blood vessel stiffening is a hallmark of hypertension (A.K.A. high blood pressure) and is thought to be a major contributor to the clinical complications of the condition, which include heart failure, stroke and renal impairment. Here we will test the novel concept that this stiffening process is caused by certain types of white blood cells (macrophages), which enter the walls of blood vessels and signal the surrounding cells to produce a rigid scaffolding protein called collagen.
Evaluating The Anti-inflammatory, Anti-oxidant And Wound-healing Properties Of Australian Native Stingless Bee Cerumen From Trigona Carbonaria, And The Effects Of Bee Foraging Behaviours On Cerumen Bioactivity

Summary
I have a keen interest in evaluating the potential of natural products to promote wound-healing in humans. Cerumen, a resinous material produced by Australian native stingless bees, is easily obtained; however, the medicinal properties of this natural product have not been widely investigated. Therefore, the proposed PhD project aims to investigate the anti-inflammatory, anti-oxidant and wound-healing properties of Australian native stingless bee cerumen.

Summary
Chronic inflammatory lung diseases like asthma and smokers lung are treated with combinations of anti-inflammatory drugs. Powerful anti-inflammatory types of steroid drugs are used in more severe disease. Even these powerful drugs are sometimes not effective enough. Our work is developing an understanding of how inflammation limits the anti-inflammatory effects of steroids and we are devising ways to overcome this with new drugs.

The Importance Of Receptor Trafficking For Signalling Of Pain And Inflammation

Funding Amount
$787,604.00
Summary
Inflammation and pain are normal processes that are essential for survival: inflammation fights infections and pain allows avoidance of danger. These processes are normally tightly controlled and are transient. During disease, they become dysregulated and chronic. By understanding the normal processes of inflammation and pain, and by determining how dysregulation causes disease, we aim to develop new treatments for diseases that are a major cause of human suffering.
ROLE OF A DOWN SYNDROME-RELATED PROTEIN IN STROKE OUTCOME
Funder
National Health and Medical Research Council
Funding Amount
$931,302.00
Summary
This project will test whether a gene called DSCR1, which is present at a higher level in Down Syndrome individuals, might play a protective role in the outcome after stroke. We will identify the cells and molecular pathways that are involved in this protective effect in mice, with a longer term view of applying this information to the development of new types of targeted therapies for clinical stroke.
Chronic inflammation underlies common and debilitating diseases and causes pain by unknown mechanisms. There is an urgent need to gain a deeper understanding of the mechanisms of chronic pain, which will allow the development of improved therapies with fewer side-effects. Our research program investigates the mechanisms of pain that are associated with inflammatory bowel disease and irritable bowel syndrome, with the goal of developing more effective and selective therapies.
Airway Smooth Muscle And Fixed Airway Obstruction: Strategies For Softening Muscle

Funding Amount
$555,643.00
Summary
In severe asthma the airways don't relax fully making breathing more difficult. The inability to relax is being addressed by exploring the behaviour of isolated muscle cells. These cells are able to compact collagen gels. The mechanisms used to compact the gel are different to those that cause rapid muscular contraction. We aim to identify the molecules responsible for the gel compaction as a first step to identifying new drugs to treat the fixed airway obstruction in severe asthma.
Targeting Small Airways To Overcome Resistance To Therapy In Asthma

Funding Amount
$531,045.00
Summary
There is a pressing need to overcome resistance to current therapies for severe asthma. Targetting inflammation-induced changes in small airway contraction offers an alternative strategy. We have identified a novel bronchodilator that relaxes maximally contracted mouse small airways when current treatment is ineffective. We will demonstrate its efficacy in animal models mimicking key features of human asthma, and define new ways to improve outcomes in poorly-controlled asthma.
Inhibitors Of Secretory Phospholipases In Diet Induced Obese Rats

Funding Amount
$581,051.00
Summary
A new drug given to rats fed a high fat-carbohydrate diet shows very promising effects in preventing and treating abdominal obesity, insulin resistance, glucose intolerance, and other risk factors for diabetes and cardiovascular disease. This project will profile biochemical and pharmacological properties of the drug in more detail in order to track down molecular mechanisms of its action and potential therapeutic benefits, guided by studies on rats, biochemical markers, rat and human fat cells.
