Unraveling Mechanisms Of Liver Transplant Tolerance

Funding Amount
$694,822.00
Summary
Liver transplants are unique amongst solid organs as they are spontaneously accepted across different individuals and induce acceptance of other organs from the same donor co-transplanted at the same time. Using a new mouse liver transplantation model, this proposal will elucidate how the liver tissue performs this function and identify new markers associated with tolerance in the blood of mice. This knowledge will be used to identify liver transplant patients with reduced rejection risk.
Deciphering How TCR Affinity Regulates CD4 T Cell Help In Immunity And Autoimmunity

Funding Amount
$850,885.00
Summary
Immune responses require the coordinated interaction and cross-talk between two types of white blood cells known as CD4 and CD8 T cells. A dysregulated interaction between these cells could be the cause of autoimmune and persistent infections by pathogens leading to chronic diseases. The aim of this proposal is to provide a deeper understanding of CD4/CD8 T cell interactions to improve immune outcomes in many chronic diseases in which interaction between these two immune cells is critical.
Transgenerational Effects Of Male Obesity - Mechanisms And Interventions

Funding Amount
$829,143.00
Summary
Childhood obesity is associated with obesity in either parent, and obese children tend to become obese adults, forming an intergenerational cycle that promotes obesity. We have identified paternal obesity as an important novel target for intervention to stop the progression of the obesity epidemic. This project investigates supplementation of obese fathers with folate to prevent the adverse impact of paternal obesity on subsequent generations.
We have discovered a single tumour factor which causes cancer cachexia, a wasting condition that is one of the worst complications of malignancy, for which there is no current effective treatment. We have developed antibodies which effectively block this condition in preclinical models and have produced human/humanised version of this. This application is to characterise these human antibodies to allow us proceed to clinical trials.
Deciphering Mechanisms Of Liver Allograft Tolerance

Summary
The liver has paradoxical properties: it is the site of effective immune responses to pathogens, but under some circumstances, it is known to induce harmless immune responses. Liver transplants are more readily accepted than other organ grafts in the absence of immunosuppressive drugs but little is known about the mechanisms that prevent an effective response. This proposal aims to unravel these mechanisms. This project will have important implications for transplantation studies.
De Novo Mutations And The Pathogenesis Of Childhood-onset Autoimmune Disease
Funder
National Health and Medical Research Council
Funding Amount
$1,406,510.00
Summary
This project aims to reveal the gene abnormalities that cause devastating autoimmune diseases to develop in some children, such as Type 1 diabetes, juvenile arthritis and autoimmune destruction of blood cells. The project will use new technologies to identify alterations in the DNA sequence of a child compared to either of their parents, and to test suspicious DNA alterations in laboratory mice in order to understand the gene effects and evaluate new treatments.

Summary
The obstructive sleep apnoea syndrome (OSA) refers to a condition in which throat blockage occurs during sleep leading to breathing difficulties, including cessation of breathing for short periods of time. OSA effects both men and women but is amongst the commonest of chronic disorders of adult males, occurring in 5% of men over the age of 45 years. In the proposed studies we will examine the effect of the pressure in the tissues surrounding the throat on the ability of the throat to stay open a ....The obstructive sleep apnoea syndrome (OSA) refers to a condition in which throat blockage occurs during sleep leading to breathing difficulties, including cessation of breathing for short periods of time. OSA effects both men and women but is amongst the commonest of chronic disorders of adult males, occurring in 5% of men over the age of 45 years. In the proposed studies we will examine the effect of the pressure in the tissues surrounding the throat on the ability of the throat to stay open and allow breathing. The major outcome of the animal studies is increased knowledge concerning mechanisms whereby collapsing forces are applied to the upper airway. This will give insights into potential factors influencing upper airway collapse during sleep in OSA patients. Of particular importance will be our studies on the effects of jaw position on the pressure exerted on the walls of the throat since the use of an intra-oral device to hold the jaw forward during sleep is one of the treatments used to prevent throat blockage during sleep. The studies in humans will examine, for the first time, the notion that the mass (weight) of the neck has a direct effect on the severity of sleep disordered breathing. If neck mass has a substantive influence on sleep disordered breathing then strategies aimed at reducing neck mass (fat) may provide a new therapeutic approach to the management of OSA patients.Read moreRead less
BioPolymer Fibres For Remodelling Mdx And Damaged Muscle

Summary
This project aims to generate new, smart polymers for use in re-building muscle that has degenerated due to disease and-or trauma damage. The merger of smart polymers with biologically based solutions and cells has great potential to improve outcomes of treatments of damaged muscle in diseases such as Muscular Dystrophy.

OSAHS affects both men and women but is amongst the commonest of chronic disorders of adult males, occurring in ~4% of men over the age of 45 years. In the proposed studies we will develop a computer model of the function of the throat during breathing. A particular focus of our model will be the influence of the properties of the tissue that form the walls of the throat. Our goal is to construct a computer model that will be useful in identifying specific features of throat function that make people susceptble to the development of OSAHS. In this manner we hope to provide a tool that can be used to develop new approaches to the treatment and prevention of OSAHS.Read moreRead less
