Summary
Pulmonary artery hypertension (PAH) is a fatal disease primarily affecting young adults. It is caused by a defect in cells that form the vessel that carries blood from the heart to the lungs. We will use stem cells made from the skin of PAH patients to examine why the blood vessel cells from these patients fail to function normally.

Summary
In Australia, coronary heart disease (CHD) causing heart attacks remains the largest cause of death, claiming a staggering 28,000 lives a year. Oxidative stress, resulting from increased production of oxygen free radicals in arteries, is an important cause of CHD, heart attacks and strokes. We seek to understand how such oxyradicals are produced in the key cells that form the lining of all arteries, known as the vascular endothelium.

Oxidative stress, resulting from increased production of oxygen free radicals in arteries, is an important cause of CHD, heart attacks and strokes. We seek to understand how such oxyradicals are produced in the key cells that form the lining of all arteries, known as the vascular endothelium. By using novel DNA-type molecules (known as anti-sense) developed in our laboratory, which block a particular gene causing oxidative stress, we will determine whether this gene is responsible for the formation of oxyradicals in human and mouse cells grown in culture. In addition, we will explore whether this gene is turned on by factors known to be involved in CHD. Finally, we will also investigate whether the good cholesterol known as HDL can act to prevent oxidative stress in human cells, as we discovered it appears to do in living arteries in vivo. If we find it has the same protective effect in endothelium, we will determine how it does this, and which component proteins of the HDL particle are important. This might suggest new treatments to prevent acute events leading to heart attack and stroke, and possibly new applications where damage appears to result from acute oxidative stress, such as in the brain soon after a stroke has occurred. We also have a plan to develop antisense drugs that will target the important gene specifically in the affected endothelium. In addition, we have other specific new drugs that will block this system in arteries. Simultaneously we will be testing the role of this gene in mouse and rabbit models of artery disease, for both our types of drugs might provide valuable new therapeutic agents to target the underlying cause of CHD and not just its symptoms as current drugs do.Read moreRead less
Defining The Impact Of Universal Iron Interventions In Young Children: A Randomized Controlled Trial In Rural Bangladesh

Funding Amount
$2,794,373.00
Summary
Although nearly half of the world's young children are anaemic, evidence regarding the best approaches to correct this problem are limited. New data even suggests that the conventional approaches (iron supplements, multiple micronutrient powders) may even be harmful. We will perform the definitive trial which will confirm the existence and magnitude of any benefit (and harm) from these interventions in young Bangladeshi children. This trial will inform global policy on anaemia control.
Benefits And Safety Of IRon Supplementation With MAlaria Chemoprevention To Children In Malawi (IRMA) - A Randomised Controlled Trial

Summary
Anaemia and malaria frequently coexist in low income settings e.g. sub-Saharan Africa and Asia. Iron interventions aim to reduce anaemia but exacerbate malaria. We aim to test whether iron is made safe by coadministering malaria prevention, and whether these interventions improve child health outcomes especially cognitive development, while ensuring malaria resistance does not emerge.
Stem Cell Based Strategies For Re-establishing T Cell Immunity In Aging And Disease.

Summary
The thymus is the organ responsible for producing T cells, a key cell type in the body’s immune system. Certain cancer treatments damage the thymus, compromising the immune system and leaving patients susceptible to opportunistic infections. This proposal will develop clinically applicable strategies for generating functional human thymic mini-organs that could eventually help restore the immune system of people receiving treatment for cancer.
The Role Of Copper In Ubiquitin-dependent Protein Degradation In Alzheimer's Disease

Funding Amount
$588,622.00
Summary
Ubiquitin’s are small proteins that tag other proteins in a process known as “Ubiquitination”. Often this is to target them for degradation once they are no longer needed i.e. to take out the rubbish. This process is disrupted in Alzheimer’s disease (AD), which may contribute to the disease. This project aims to find out if copper, an essential metal for life, is required for this process. Drugs that are designed to deliver copper to brain cells have been effective in small AD clinical trials.

Summary
There has been a dramatic and unexplained increase in food allergy over recent decades. The increase in food allergy may relate to a concordant increase in early vitamin D insufficiency, however this hypothesis has never been directly tested. This project will use existing/funded samples from two NHMRC funded studies to conduct a detailed investigation of (i) the determinant and predictors of early life vitamin D insufficiency; and (ii) the association of vitamin D insufficiency and food allergy ....There has been a dramatic and unexplained increase in food allergy over recent decades.

Summary
Anaemia, malaria and HIV affect millions of people worldwide, but interactions between these conditions are poorly understood. A haematologist with training in public health, my interest is in finding ways to control the enormous global burden of anaemia. My research will focus on how iron status influences infection with malaria and HIV. It will provide evidence for anaemia control guidelines and help improve global policies for controlling iron deficiency where these infections coexist.
