This project is about the way that the brain controls reproduction. It is important because there is no known cause for infertility in a significant number people with such a problem. The project should inform us on new ways to manage particular forms of reproductive failure.
Gonadotropin Inhibitory Hormone (GnIH); A Negative Regulator Of Reproduction
Funder
National Health and Medical Research Council
Funding Amount
$752,936.00
Summary
Gonadotropin inhibitory hormone (GnIH) is a short peptide of 8 amino acids that is produced by the brain and acts in a negative manner on brain and pituitary cells that control reproduction. This project aims to elucidate the role of GnIH in normal physiology and in states of stress and negative metabolic state. Work will be carried out in various species to define the function of the peptide and also to investigate ways that it can be utilised to prevent reproduction.
THE EFFECT OF STRESS AND ENVIRONMENTAL ENRICHMENT ON DISEASE PROGRESSION IN MESIAL TEMPORAL LOBE EPILEPSY

Funding Amount
$578,201.00
Summary
Mesial temporal lobe epilepsy, the most common form of drug-resistant epilepsy in adults, is a progressive neurodegenerative condition for which there is currently no effective disease modifying treatment. This proposal will explore whether co-morbid stress accelerates disease progression in MTLE, and whether targeting stress pathways by medical and environmental manipulations can mitigate against this.
The Influence Of NF-KB In The Development Of Autoimmunity And Cancer In Fas/FasL Mutant Mice

Summary
Apoptotic cell death is an essential process in the human body, it removes useless and dangerous cells, preventing autoimmune disease and cancer. Apoptosis is activated when the surface receptor Fas is stimulated by its ligand, FasL, but defective signalling causes disease associated with deregulated NF-?B activation. We will investigate how faulty FasL-induced apoptosis cooperates with deregulated NF-kB activation or defective Aire (immunological tolerance orchestrator) results in autoimmunity.
The Role Of NOD Proteins In T Cell Development And Function.

Summary
The long-term goal of this project is to understand the role of NOD proteins in the T cell branch of the immune system. Distorted T cell responses can lead to over-activation and autoimmunity, or host susceptibility to microbial infection. This project aims to provide a deeper understanding of NOD proteins in chronic inflammatory diseases like Crohn’s disease, where altered NOD signaling may generate intrinsic T cell defects, in addition to altered microbial sensing and host protection by the in ....The long-term goal of this project is to understand the role of NOD proteins in the T cell branch of the immune system.

PACAP: The Mechanism Underlying Sleep Apnoea-induced Hypertension

Funding Amount
$505,117.00
Summary
10% of Australians suffer from sleep apnoea; a cause of high blood pressure. Untreated, high blood pressure causes heart failure, kidney failure and stroke. A major cause of high blood pressure is an increased amount of nerve activity that controls the heart and blood vessels. In this proposal we will investigate how a brain chemical, called PACAP, affects nerve activity and blood pressure in a model of sleep apnoea. This information may lead to new and better treatments for high blood pressure.
Applying Quantitative Immunology To The Analysis Of Complex Genetic Diseases

Funding Amount
$864,596.00
Summary
The immune response of each individual varies. For some, the response invoked by foreign challenge is weak, leading to a lifetime of difficulty with infection. For others, the response is stronger, yielding excellent immunity, but opening the potential for overactive responses to self-material and autoimmune disease. We have a new theory for how the health of our immune system can be measured and we aim to apply it to understand the genesis of the many different forms of human immune diseases.
Functional Analysis Of A Novel Genetic Mouse Model For Congenital Growth Hormone Deficiency
Funder
National Health and Medical Research Council
Funding Amount
$519,131.00
Summary
Pituitary Hormone deficiency is not uncommon and is associated with poor growth, metabolism and fertility. Some cases of this disorder arise due to genetic changes that compromise the ability of the pituitary gland to make or secrete growth hormone (GH). Using cutting-edge genomics technology, we have generated a new genetic mouse model of GH deficiency. The aim of this project is to understand the function of this novel GH _regulating gene in mice and in humans.
Defining The Molecular Regulators Of Apoptotic Cell Disassembly And Their Role In Cell Clearance And Lupus-like Autoimmune Disease

Funding Amount
$773,848.00
Summary
In humans, billions of cells will die daily as part of normal turnover in various organs. It is vital that dying cells are rapidly removed as their accumulation has been linked to autoimmunity and inflammation. To aid efficient removal of dead cells, dying cells can disassemble into smaller fragments for neighbouring cells to engulf. We aim to understand the machinery that controls how dying cells can disassemble into smaller pieces and their function in cell clearance and autoimmunity.
The Mechanism For Combined Immunodeficiency And Autoimmunity Due To STK4-deficiency And Its Broader Application To Human PIDs

Funding Amount
$648,371.00
Summary
Why do some patients develop autoimmune diseases such as lupus where the immune system makes antibodies that attack its own body? To answer this, we plan to study a disease where a gene responsible for making antibodies is defective. Patients with mutations in the STK4 gene are unable to regulate the selection processes by which only the right cell is chosen to make antibodies. Understanding how STK4 works may help us unlock the mystery of what causes lupus.
