Many drugs modulate the function of proteins imbedded in cell membranes. Extensive research has been undertaken to better understand drug interactions with these proteins to improve drug therapies, but there has been relatively little progress in understanding the role of the cell membrane. This project will investigate how the cell membrane influences protein function and then use this information to develop novel drugs for the treatment of neurological disorders.
Investigating The Link Between Oxidative Stress And Biomechanical Integrin Activation In Diabetes

Summary
Diabetes represents a serious healthcare problem globally. A large proportion of deaths associated with diabetes can be attributed to the development of blood clots in the circulation of the heart and brain (heart attack/stroke). The blood clotting mechanism is ‘hyperactive’ in diabetes, although the reason for this is not well defined. In this proposal we will investigate a new mechanism promoting blood clots, and will investigate innovative approaches to reduce this clotting mechanism.
Understanding Sphingolipid Mediators Of Insulin Resistance

Summary
Sphingolipids are a class of lipid metabolites that have a variety of functions within cells. It has been known for some time that an accumulation of excess lipid, including certain sphingolipids, can adversely impact insulin action and glucose metabolism in cells. In this project we will a combination of strategies to test the hypothesis that the sphingolipid profile can be manipulated to have favourable effects on metabolism.
Alcoholic Chronic Pancreatitis: Induction, Progression And Reversal

Funding Amount
$632,211.00
Summary
Pancreatitis (inflammation of the pancreas) is a serious complication of alcohol abuse. Patients suffer from severe and often intractable abdominal pain, maldigestion and diabetes, We have recently shown that gut toxins (endotoxins) may act as a trigger factor for pancreatitis in alcoholics. The proposed project aims to characterise the effects of gut toxins on the pancreas during alcohol abuse so as to identify pathways that may be therapeutically targeted to prevent or retard the disease.
Regulation Of Secretion Of The Fungal Virulence Determinant, Phospholipase B

Summary
Serious systemic infections due to fungi have increased dramatically in the past few years, especially in people with poorly functioning immune systems. Treatment of these conditions is problematic because the few drugs which are available are not highly effective, and-or cause significant side-effects. Little is understood of how fungi cause disease, and this problem must be addressed if these infections are to be contained. We have discovered that the enzyme, phospholipase B (PLB), is secreted ....Serious systemic infections due to fungi have increased dramatically in the past few years, especially in people with poorly functioning immune systems. Treatment of these conditions is problematic because the few drugs which are available are not highly effective, and-or cause significant side-effects. Little is understood of how fungi cause disease, and this problem must be addressed if these infections are to be contained. We have discovered that the enzyme, phospholipase B (PLB), is secreted by the disease-causing fungus, Cryptococcus neoformans, and that it is important in enabling the fungus to invade the host's cells and spread around the body from the lungs to the brain, where it can cause meningoencephalitis. PLB is also produced by other disease-causing fungi. The mechanism of PLB secretion is completely unknown. In this project we aim to determine the pathways involved in PLB secretion with the intention of exploiting steps unique to pathogenic fungi, for the future design of new anti-fungal drugs.Read moreRead less
