Summary
In normal individuals, special cells in the pancreas - beta cells - secrete insulin. Insulin controls blood glucose. However, in diabetes, these beta cells have failed and are unable to perform their function, possibly due to faulty energy production. This project examines the underlying biochemical processes, in particular the energy requirements for insulin secretion. If we can repair this fault, it could identify novel targets for the treatment of diabetes.
Functional And Structural Studies Of A Glycosyltransferase Essential For Complex Glycolipid Biosynthesis In Mycobacteria

Summary
Tuberculosis (TB) kills more than three million people each year while the causative bacterial species, Mycobacterium tuberculosis, infects one-third of the entire human population. An alarmingly high rate of TB exists in Australia's indigenous population. This proposal aims to identify and characterise essential processes involved in synthesis of the outer coat of the bacterium which are potential targets for new drugs for the treatment of this devastating disease.

Summary
Tuberculosis (TB) is one of the most devastating diseases in human history. TB kills approximately two millions people each year worldwide, more than any other disease caused by a single infectious agent. The disease has re-emerged in recent years due to the AIDS epidemic and the appearance of TB bacteria that are not killed by currently available antibiotics.

TB kills approximately two millions people each year worldwide, more than any other disease caused by a single infectious agent. The disease has re-emerged in recent years due to the AIDS epidemic and the appearance of TB bacteria that are not killed by currently available antibiotics. New antibiotics must be developed to combat this global health threat. This requires the identification of targets on the bacteria on which antibiotics can act. One particularly attractive target is the outer coat of the bacterium. Several existing antibiotics target the bacterial coat, yet the ways in which coat is assembled are poorly understood. Two related compounds in the bacterial coat, and unique to TB bacteria, are called PIMs and LAMs. The structures of these compounds are known, and the compounds appear to be essential for the survival of the bacteria in the human host. However, the mechanisms by which PIMs and LAMs are made by the bacteria are very poorly understood. The aim of our research proposal is to better understand the process by which these compounds are made. If this process can be blocked by an antibiotic, then this represents a potential anti-TB therapy which could save millions of lives worldwide.Read moreRead less
