Enhancing The Immune Response To Disordered Malaria Antigens

Summary
Half of the worlds population live at risk of malaria, and the disease kills half a million people a year, predominantly young children. Despite recent progress, a vaccine with the efficacy required to help control and ultimately eradicate malaria remains out of reach. This project studies an important class of proteins likely to form part of a future malaria vaccine, and will develop new ways to improve their effectiveness as vaccine components.
It is estimated that one quarter of people over the age of 65 suffer from some form of memory impairment, mostly in the form of AlzheimerÍs disease. The enormous economic and social costs of the disease and an aging population make it a major health problem. This work will lead to atomic structures of proteins centrally involved in the disease, thus increasing our understanding of the molecular mechanisms of the disease and form the basis for the design of drugs to combat it.
Resolving And Targeting The Complex Molecular Mechanisms Underlying GPCR Signalling

Funding Amount
$1,071,370.00
Summary
Receptors are located on the surface of all human cells to allow our cells to respond to their environment. Over 30% of prescription drugs act through particular receptors called GPCRs, however effective drugs without side effects are difficult to develop because we do not have a deep understanding of how GPCRs transmit complex signals. In this proposal we seek to resolve the atomic-level details of GPCR signalling to assist in the development of better drugs for a diverse range of diseases.
Rational Development Of Novel Analgesics For The Treatment Of Chronic Pain

$595,945.00
Summary
Chronic pain is a major global health problem that currently affects over three million Australians. There are few drugs available for treatment of chronic pain and most have significant side-effects. Individuals lacking a particular type of ion channel known as Nav1.7 are completely insensitive to pain, but are otherwise normal. Block of this channel therefore appears to be an ideal avenue for pain relief. This project aims to produce selective Nav1.7 blockers that can be used as analgesics for ....Chronic pain is a major global health problem that currently affects over three million Australians.

A New Class Of Anti-Malarial Agents Targetting Apical Membrane Antigen

Funding Amount
$597,598.00
Summary
Malaria is a major global health problem that imposes a substantial burden on the world’s most vulnerable societies. The invasion of host cells by malaria parasites represents an attractive target for therapeutic intervention, and Apical Membrane Antigen 1 (AMA1) plays an essential role in this process. Agents that bind to a key interaction site on AMA1 prevent host cell invasion and thus represent starting points for the development of a new class of anti-malarial drugs.
Inhibitors Of Inducible Nitric Oxide Synthase (iNOS) Regulation As A Basis For Novel Anti-Infective Agents

Funding Amount
$643,735.00
Summary
The human enzyme iNOS generates reactive nitrogen species that are required for the intracellular killing of pathogens such as bacteria and parasites. Recently, we showed that the SPSB proteins are key regulators of this important enzyme, and that interfering with this regulation enhanced the anti-microbial actions of iNOS. This project will develop small molecule inhibitors of the SPSB-iNOS interaction for use as novel anti-infective agents in humans.
Understanding How Toxins Interact With Lipid Membranes And Ion Channels
Funder
National Health and Medical Research Council
Funding Amount
$598,220.00
Summary
Chronic pain affects one in five Australians and current treatments have limited effectiveness, with only about one third of patients getting meaningful, pain relief. The aim of the current project is to create alternative treatments for pain that can potentially lead to the reduced suffering and improvement of life quality of many Australians. To achieve this aim we propose to study how spider toxins interact with cells and deactivate sensor targets responsible for chronic pain.
Understanding How Perforin Forms Pores: The Role Of Calcium And Lipids.
Funder
National Health and Medical Research Council
Funding Amount
$797,813.00
Summary
This grant aims to study perforin, a key part of the mammalian immune system. The work will facilitate the development of perforin inhibitors. It is anticipated that these data will be of utility in developing first in class drugs to improve the success of bone marrow transplantation.
Burkholderia Pseudomallei Disulfide-forming Proteins: Structure, Function And Inhibition
Funder
National Health and Medical Research Council
Funding Amount
$707,032.00
Summary
Our research will lead to a better understanding of melioidosis, a disease endemic to Northern Australia and which impacts indigenous communities at twice the rate of the rest of the population. This project will also aim to generate new compounds with the potential for development as treatments against this devastating disease.
Defining The Molecular Mechanisms Of Lyssavirus Replication And Immune Evasion: The P Protein Axis
Funder
National Health and Medical Research Council
Funding Amount
$900,995.00
Summary
Lyssaviruses such as rabies virus (RABV) and Australian bat lyssavirus cause rabies disease, which has the highest case-fatality rate of known infectious diseases, causing >60,000 human deaths/year. Critical to this is a protein produced by the virus that is important for both viral growth and evasion of the host's immune defences. This project aims to understand the molecular mechanisms underlying these processes, which may lead to new approaches to combat currently incurable viral diseases.
