Neurotransmitter transporters are very good drug targets because modulation of their activity can lead to up and down regulation of neurotransmitter concentrations and thereby influence signalling pathways in the brain. This can be very useful in treating various neurological disorders and also altering normal brain functions such as learning and memory.

This can be very useful in treating various neurological disorders and also altering normal brain functions such as learning and memory. In this project we will develop a detailed understanding of how glutamate transporters work and in so doing will be in a better position to design subtype and transporter-specific compounds. These compounds will be very useful in defining the role of glutamate transporter subtypes in normal and pathological states and may be useful in treating neurological disorders such as Alzheimer's disease, schizophrenia, ishaemia following a stroke, and motor neurone disease.Read moreRead less
Molecular Dissection Of The Munc18c:Syntaxin4 Complex Required For Insulin-regulated Exocytosis In Adipocytes

Funding Amount

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.
Molecular Basis For RIG-I Like Receptor Activation Of The Innate Immune Pathway.

Funding Amount
$564,770.00
Summary
This project is to understand how proteins in the cell detect the presence of invading viruses, and pass on the message for the cell to produce defence molecules. The overproduction of these defence molecules can lead to inflammatory diseases. This research will help us to understand the process of the innate immune response in cells and how we might control it in disease states.
Immunological Changes During Pregnancy And The Impact On Viral Hepatitis Infection

Summary
Hepatitis B virus (HBV) can cause long term health problems particularly affecting the liver and can be passed from mother to baby. Despite the availability of a HBV vaccine babies can still become infected. During pregnancy there are changes in a woman’s immune system which may impact on HBV infection and make transmission to the baby more likely. This research aims to explore the changes in a woman’s immune system and the impact this has on risks for hepatitis and transmission to the baby.
Mechanism Of Activation Of JAK2 By A Class 1 Cytokine Receptor

Funding Amount
$562,742.00
Summary
Cytokine receptors regulate key processes such as red/white blood cell formation, stature, adiposity and lactation. They use JAK kinases to signal to regulated genes. Here we will use sophisticated technologies able to observe single molecules and crystallography to uncover the mechanism used by these receptors to signal into the cell using a well characterised, simple cytokine receptor, the growth hormone receptor.
