The Immunoregulatory Role of the Endogenous Cannabinoid Anandamide. Anandamides are naturally occurring fatty acids that act at the cannabinoid receptor expressed in the brain and periphery. A new proposal by our research group challenges traditional models of the disease process by suggesting that the anandamide system is an important imunoregulatory system that can be targeted by invading pathogens. We propose that disruption to the anandamide system, by bacteria or viruses acting at the rece ....The Immunoregulatory Role of the Endogenous Cannabinoid Anandamide. Anandamides are naturally occurring fatty acids that act at the cannabinoid receptor expressed in the brain and periphery. A new proposal by our research group challenges traditional models of the disease process by suggesting that the anandamide system is an important imunoregulatory system that can be targeted by invading pathogens. We propose that disruption to the anandamide system, by bacteria or viruses acting at the receptor to block immunological responses, contributes to chronic illness states. At this point we have good evidence that anandamides are immunoregulators, however, we have very little knowledge of their precise physiological role. The aim of this research is to begin to characterise the immunoregulatory role of the anandamide system. This project will provide a comprehensive understanding of this endogenous control system, the immunological properties of which have not previously been described. The outcome of this research may lead to the identification of new avenues for the development of pharmaceutical interventions that can target this system.Read moreRead less

Summary
Novel postsynaptic functions of the microtubule-associated protein tau. The protein tau is present in abnormal deposits in brains of individuals with dementia. The main aim of this project is to unravel and understand in detail new roles of tau in neurons and thus shed new light into normal brain function. Understanding these new functions of tau will aid in identifying new ways to treat these debilitating diseases.
Cellular mechanisms that protect against copper-bound beta-amyloid. This project will investigate some of the brain’s own mechanisms for protecting itself against Alzheimer’s disease. Understanding these mechanisms will be important for developing future therapeutic strategies for treating Alzheimer’s disease.

Summary
Fluorescence microscopy with optical tweezers: imaging cellular responses. Life relies on the ability of our cells to receive and respond to signals with pinpoint accuracy, involving both chemical and mechanical signals. This equipment will allow scientists to expose cells to both types of signals and measure the response at an unprecedented level of accuracy for the first time.

Imaging cell and tissue architecture using confocal and super-resolution microscopy: This project aims to understand how the architecture of cells and tissues is controlled. This is because the organisation of biological space underpins the function of cells, tissues and organisms. This project will test the role of identified parts of cell architecture in regulating specific animal functions/pathologies. It will do this by using new microscope technologies which are at the frontier of visualising cell structure in isolation and in the context of tissue including application to the living animal. The dynamic organisation of structures in cells will be imaged in living tissue. Novel insights into structure/function relationships in the body will impact the health industry and generate opportunities for new diagnostics and therapeutics. Read moreRead less
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

The consortium brings together laboratory, neuroimaging and computational expertise in a comprehensive framework for imaging the mouse brain. This will help researchers to study mouse models of genetic and acquired disorders across the life-span. Remote viewing and analysis capabilities will help overcome the 'tyranny of distance', increasing national access to the facility. Repositories of digitised images will increase the availability of valuable research material to other Australian and international researchers.Read moreRead less
CD4 T cell programming by neonatal and early-life infection. T lymphocytes (T cells) are white blood cells that play a critical role in protecting the body from infection. Before T cells can function they need to be programmed so that they can specifically respond to an infectious agent (a type of bacteria or virus). Inappropriate programming can lead to disease. Whether T cells respond to an infectious agent or foreign substance in a protective or destructive manner may critically depend on the ....CD4 T cell programming by neonatal and early-life infection. T lymphocytes (T cells) are white blood cells that play a critical role in protecting the body from infection. Before T cells can function they need to be programmed so that they can specifically respond to an infectious agent (a type of bacteria or virus). Inappropriate programming can lead to disease. Whether T cells respond to an infectious agent or foreign substance in a protective or destructive manner may critically depend on the age that an individual first encounters the infection. Our project will identify critical periods in life that direct T cell programming to subsequent protective or destructive responses, providing new insights into the developing immune system that may be exploited to treat disease or develop vaccines.Read moreRead less

Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function that occur during development of addiction and relapse that are critical for development of better strategies to treat the disorder.
