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.

Summary
Heroin addiction is a major health and societal problem in Australia. It is consistently associated with an adverse impact upon individual users, their families, and communities. It is a chronically relapsing condition for which few, if any effective prevention and treatment strategies exist. Moreover, why an individual initiates and maintains heroin taking remains unclear.

It is consistently associated with an adverse impact upon individual users, their families, and communities. It is a chronically relapsing condition for which few, if any effective prevention and treatment strategies exist. Moreover, why an individual initiates and maintains heroin taking remains unclear. Stress and negative emotions have a strong impact on heroin use. Stress may drive some individuals to start using heroin, stress increases the pleasurable effects of heroin and stress increases the aversive effects of heroin withdrawal. These effects will encourage addiction and discourage addicts from seeking treatment. Stress can also cause an otherwise drug-free individual to relapse to heroin addiction despite having been drug-free for some time. In this project we will study why stress has such a large impact on heroin addicts and heroin addiction. We will test the hypothesis that heroin use actually produces profound alterations in the neural network in the brain which controls responses to stress. This project uses a simple animal model of heroin addiction whereby rats are injected with morphine to study the regulation of several genes which are important in responding to stress. We will also study how this exposure and changes in gene expression alter neurobiological, cardiovascular, and behavioural responses to stress. This project will identify parts of the brain that are altered during heroin addiction, and will also identify why heroin addicts are more vulnerable to stress than the general population. Therefore, this project will help us to identify targets for therapeutic intervention (both psychological and pharmacological) and possibly disrupt the addictive cycle.Read moreRead less

This Proposal continues the development of the initial Type 1 Diabetes Clinical Research Network (CRN), launched by JDRF in June 2011 with a $5m grant from the Australian Government.
The principal goal of the CRN is to positively impact the life of people with T1D in Australia through the support and promotion of clinical research. A further electoral commitment of $35m over 5 years will enable further progress towards finding a cure for T1D, including delivering better and faster access to new therapies and treatments that can help prevent and manage the disease.

Real-time imaging of the initiation of adaptive immunity in vivo. Understanding the first few hours of an immune response is fundamental to understanding how the human immune system functions. The immune system mounts our responses to infectious diseases, but can also cause autoimmune disease, allergy, and organ graft rejection. We will study how naive antigen-specific T cells first contact antigen in lymph nodes using 2-photon intravital microscopy. The research has the potential to change the ....Real-time imaging of the initiation of adaptive immunity in vivo.

The immune system mounts our responses to infectious diseases, but can also cause autoimmune disease, allergy, and organ graft rejection. We will study how naive antigen-specific T cells first contact antigen in lymph nodes using 2-photon intravital microscopy. The research has the potential to change the way we think about the clonal selection of lymphocytes, the fundamental theory underlying our understanding of the immune system.Read moreRead less
Development of chaperonin 10-based second generation biopharmaceuticals for treatment of inflammatory diseases. Diseases caused by malfunctioning of the body's immune system (inflammatory diseases) such as rheumatoid arthritis, psoriasis and Crohn's disease cause illness in all cultures and societies, and impose financial strain on health care providers. Current treatment relies on biopharmaceuticals that block inflammatory mediators in the body or with pharmaceuticals such as anti-inflammatory ....Development of chaperonin 10-based second generation biopharmaceuticals for treatment of inflammatory diseases. Diseases caused by malfunctioning of the body's immune system (inflammatory diseases) such as rheumatoid arthritis, psoriasis and Crohn's disease cause illness in all cultures and societies, and impose financial strain on health care providers. Current treatment relies on biopharmaceuticals that block inflammatory mediators in the body or with pharmaceuticals such as anti-inflammatory drugs; both these treatments may have serious side effects. Cpn10 suppresses the body's inflammatory response while maintaining immune function to combat infections. The project seeks to develop new, safe and effective biopharmaceuticals based on Cpn10 for the treatment of a variety of chronic inflammatory diseases and autoimmune disorders.Read moreRead less
NOVEL THERAPEUTICS FOR AUTOIMMUNE DISEASE USING MOUSE SCREENING MODELS. The project aims to use experimental models of human autoimmune disease in the mouse for the testing of developmental isoflavonoid compounds produced by the Industry Partner, for protective effects against autoimmunity. The murine models proposed will duplicate human autoimmune cardiomyopathy, systemic lupus erythematosus and multiple sclerosis, encompassing both organ-specific and systemic autoimmune diseases.

Investigating the atomic structure of an immune cell inhibitory receptor. T cells play a key role in the adaptive immune system, whose reactivity must be controlled to prevent aberrant reactivity. Central to the function of T cells is the T cell antigen receptor, and a host of co-stimulatory molecules, co-receptors and inhibitory receptors.

Central to the function of T cells is the T cell antigen receptor, and a host of co-stimulatory molecules, co-receptors and inhibitory receptors. This proposal, in partnership with Immutep Ltd, aims to gain a basic understanding of the structure and function of a key inhibitory receptor found on T cells, termed the Lymphocyte activation gene-3 (LAG-3). The proposal utilises a combination of cellular immunology and structural biology to gain insight into the form and function of the LAG-3 molecule. Ultimately this fundamental knowledge can be used by the biotechnology industry.Read moreRead less
