Targeting Toxoplasma Gondii Latent Stages Responsible For Chronic Disease

Funding Amount
$697,107.00
Summary
Many microbial pathogens become resistant to host immune response and drugs by entering a slow-growing, dormant state. These stages are commonly responsible for long term, chronic infections. We will investigate the molecular basis of dormancy in Toxoplasma gondii, which infects one in three people. These studies will identify metabolic pathways that are essential for dormancy with the view of developing new therapies for treating long term, recurrent infections.
Identification Of Novel Strategies To Mediate Immunity Against Intracellular Pathogens

Funding Amount
$325,084.00
Summary
The immune system consists of two arms - innate and adaptive. Current vaccine strategies rely mainly on adaptive features of the immune system to mediate immunity against pathogens. Many pathogens have evolved sophisticated strategies to manipulate the adaptive immune system to render it ineffective. This project will investigate microbial detection by the innate immune system, and aims to discover novel, more effective strategies to mediate immunity against intracellular pathogens.
Exported Malaria Kinases And Red Blood Cell Remodeling

Funding Amount
$408,710.00
Summary
Malaria is a serious disease affecting half the world's population and every year, more than a million people (mostly children) die as a result of the infection. Our work will help us to understand how malaria parasites alter human red blood cells and make them stick in organs such as the brain. Preventing infected red cells from becoming stiff and sticky by developing new drugs will open up new lines of attack to combat this devastating disease.
The Mechanism Of Action Of New 5-nitroimidazole Drugs Which Are Effective Against Metronidazole-resistant Giardia

Funding Amount
$292,216.00
Summary
We have discovered new 5-nitroimidazole drugs which can overcome giardial resistance to metronidazole, the most prescribed 5-nitroimidazole drug to treat giardiasis. We will focus on defining mechanisms of action of these new 5-nitroimidazole drugs in the anaerobic gut protozoan parasite Giardia. Using biochemical techniques, we will determine whether our potent new drugs are activated more efficiently by the same mechanisms as metronidazole or by novel enzyme pathways in the parasite.
Evolution And Targeting Of Polysaccharide Biosynthesis In Leishmania Parasites

Funding Amount
$449,484.00
Summary
Leishmania are parasitic protozoa that cause devastating diseases in humans. This proposal will identify the enzymes involved in the biosynthesis of an unusual carbohydrate reserve material that accumulates in pathogenic stages of these parasites. Information on the structure and mode of action of these enzymes will be used to develop novel drugs that will be tested for anti-parasite activity.
SBP1 And Altered Structure And Function Of Malaria-infected Red Blood Cells
Funder
National Health and Medical Research Council
Funding Amount
$439,550.00
Summary
Malaria is a serious disease affecting half the world's population. Every year, more than a million people (mostly children) die as a result of being infected with malaria parasites. Our work will help us to understand how the parasites alter normal human red blood cells and make them stick in organs such as the brain. Preventing the red blood cells from becoming sticky with new drugs will open up new lines of attack to combat this devastating disease.
Fetal Immune Response To Vertical Transmission Of Toxoplasma Gondii

Funding Amount
$320,891.00
Summary
Toxoplasma gondii is a parasite that is a leading cause of human abortion and congenital infections of newborns. In addition, recent research implicates Toxoplasma in diagnoses of schizophrenia and other neuromental conditions. Study of Toxoplasma, it's transmission and effects of infection and development of tools such as vaccines and diagnostic technologies will lead to an improvement in health of mothers, newborns and the wider population.
