Summary
Apoptosis is a form of cell suicide that is vital in human development and health by removing damaged or unwanted cells in a regulated manner. Disturbances in this pathway are known to be the cause of cancers and other diseases. This research will investigate how the pivotal step in cell death, termed mitochondrial outer membrane permeabilisation (MOMP) is regulated.
Unraveling The Dynamic Munc18a:Syntaxin1 Interaction Required For Neurotransmission

Summary
Membrane trafficking, the topic of the 2013 Nobel prize in Medicine, is required for delivery of cellular cargo. This research will investigate the interactions and structures of proteins from the neuronal membrane trafficking system. Understanding how this system operates will expand our knowledge of processes fundamental to learning and memory and may ultimately lead to development of selective therapeutics for treating a range of diseases.
Molecular Dissection Of The Munc18c:Syntaxin4 Complex Required For Insulin-regulated Exocytosis In Adipocytes

Summary
When blood glucose levels are high, insulin signals to fat and muscle cells to remove glucose from the blood. The uptake of glucose relies on membrane fusion events that deliver a specific glucose transporter protein to the cell surface in response to insulin signals. This process is affected in Type II diabetes. Our research will characterise the regulation of these membrane fusion events and will be important for understanding how insulin signals are communicated in health and disease.
The Role Of Intracellular Protein Trafficking In Alzheimer's Disease

Summary
Alzheimer’s disease (AD) is a progressive neurological disorder and is the most common cause of dementia. The development of therapies must be preceded by a thorough understanding of the molecular processes that underpin the disease. In this project we will examine the interactions between the Alzheimer’s precursor protein (APP) and the molecular machinery that controls its intracellular localization and breakdown to the toxic A? peptide that is central to disease pathology.
Understanding How Membrane Trafficking Controls The Levels Of Alzheimer's Disease Causing A? Peptides

Summary
Alzheimer’s disease is a progressive neurological disorder and is the most common cause of dementia. No effective treatments are currently available. The toxic amyloid peptide is central to disease pathology and is derived from breakdown of the Alzheimer’s amyloid precursor protein (APP). In this project we will examine the interactions between APP and the molecular machinery that controls its location in the cell and subsequent degradation.
The Role Of Protein Glycosylation In The Malaria Parasite

Summary
The parasites that cause malaria have unique proteins on their surface that are essential for infection of humans. These proteins are useful for making vaccines to train our immune system to recognize and block infection by the malaria parasite. Our latest research has shown that these proteins are modified with sugars that enhance parasite virulence. We are studying these modifications more closely to facilitate the development of improved malaria vaccines.
Many bacterial pathogens invade host cells to replicate and avoid detection by the host. These pathogens interact with the host and by manipulating it to its benefit they establish an environment to survive in. A detailed understanding of the targeted hosts pathways and which are essential for pathogen survival is knowledge that will allow future development of therapeutic intervention strategies.
