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
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.
The effect of competition and doctor heterogeneity on prices charged by doctors. Prices charged by doctors can have important effects on health care costs, access to health care and health status. This research will examine the determinants of prices charged by doctors. The results will be important in understanding the pricing practices of doctors and their impact on health care costs.
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. 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 way we think about the clonal selection of lymphocytes, the fundamental theory underlying our understanding of the immune system.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

Mechanism of transmission of calcium waves by glial cells. This research concerns determining the fundamental properties of cells that occupy about 70% of the brain, the glial cells. Two very important discoveries on glial cells have recently been made, namely that they can convey information in the form of patterns of waves and that they possess molecules on their surface membranes that have been implicated in psychotic disorders. One such molecule is called the D2 receptor and its malfunctioni ....Mechanism of transmission of calcium waves by glial cells. This research concerns determining the fundamental properties of cells that occupy about 70% of the brain, the glial cells. Two very important discoveries on glial cells have recently been made, namely that they can convey information in the form of patterns of waves and that they possess molecules on their surface membranes that have been implicated in psychotic disorders. One such molecule is called the D2 receptor and its malfunctioning has been implicated in schizophrenia. Our research will determine the way in which information is propagated in the glial system of the brain and also illuminate the function of several of the molecules found on the surface of the glial cells.Read moreRead less
