These diseases are caused by infection with the larval stages of tapeworm parasites which have a worldwide distribution and cause substantial human morbidity and mortality.

These diseases are caused by infection with the larval stages of tapeworm parasites which have a worldwide distribution and cause substantial human morbidity and mortality. The parasites are transmitted to humans from animals. Methods for control of transmission of infection currently rely on public education and anthelmintic treatment of animals. These measures are often ineffective and there is an urgent need for new tools to help control transmission of these important diseases. Previous research has shown that the animal hosts of these parasites can be protected from infection by vaccination. Prevention of infection in the parasites' animal hosts has the effect of breaking the parasite life cycle and indirectly removes the source of infection for humans. This project will further develop an existing vaccine against hydatid disease, will develop a new vaccine against cysticercosis and will participate in initial international parasite control campaigns based on application of these vaccines.Read moreRead less
Immunological Prevention Of Cysticercosis And Hydatid Disease

Summary
Cysticercosis and hydatid disease are caused by infections with the larval stages of tapeworm parasites. They are zoonotic diseases, transmitted to humans from animals. This project aims to develop practical vaccines to assist with the prevention of these diseases in humans. We will vaccinate the parasites' natural animal hosts and, thereby, break the parasite life-cycles, indirectly and inexpensively preventing the diseases being passed to humans.
Understanding The Development Of Humoral Immunity To Malaria Merozoites

Summary
We will examine the acquisition of antibody responses to various P. falciparum surface antigens and their association with reduced risk of re-infection and symptomatic malaria in a treatment re-infection study of children from a malaria endemic area of Papua New Guinea. The effector mechanisms by which protective antibodies control parasite burden will be idendify. Defining the antigenic targets and effector mechanisms of immunity is essential for developing anti-malarial vaccines.
The Role Of Parasite Adhesins In Plasmodium Falciparum Invasion Of Human Erythrocytes

Summary
Invasion of red blood cells is essential for the survival of malaria parasite within the human host. Red blood cell invasion is mediated by recognition of parasite proteins to specific blood surface receptors. My research focuses on understanding these parasite protein-host receptor interactions with emphasis on translating these findings as novel approaches for the prevention and treatment of malaria.
A Helminth-derived Peptide Is A Novel Prophylactic And Therapeutic Treatment For Autoimmune Disease

Funding Amount
$658,778.00
Summary
Parasitic worms (helminths) secrete molecules that possess a remarkable ability to skew the mammalian immune system towards anti-inflammatory responses. We have expoited a novel peptide secreted by helminths, which offers tremendous potential for the development of novel prophylactic and therapeutic treatments for a range of immune-mediated conditions. The overarching aim of this project is to further elucidate the mechanism of action and to determine the peptide’s clinical application.

Cysticercosis and hydatid disease are caused by infections with the larval stages of tapeworm parasites. They are life-threatening zoonotic diseases, transmitted to humans from animals and are most common in people living in poor countries.

Regulation Of Immune Mechanisms By Pathogen Cysteine Proteases

Funding Amount
$424,676.00
Summary
To survive, parasites have evolved many strategies to control the human immune system. We have identified an enzyme secreted by parasites that can manipulate cells of the immune system, subsequently preventing the development of inflammatory responses. We will investigate the mechanism involved and determine whether this enzyme could be exploited for therapeutic purposes to switch off inflammation in autoimmune disease such as type-1 diabetes.
Therapeutic Potential Of Hookworm Secreted Molecules For The Treatment Of Human Autoimmune Diseases

Funding Amount

Summary
In developed countries, the increased incidence of allergic and autoimmune diseases has been related to the decreased prevalence of parasitic infections. The present research will explore the role that parasite molecules play in mechanisms that regulate the immune response of their vertebrate hosts and test their potential to become novel therapeutics for the treatment of inflammatory diseases.
Effector Export In P. Falciparum Infected Human Erythrocytes

Funding Amount
$1,066,920.00
Summary
We will investigate malaria, a parasitic disease that kills over 450,000 people a year. We will explore how the parasite identifies, invades and remodels the host cells in which it lives, scavenging nutrients and hiding from the immune system. We will characterize the proteins involved in these critical events, as they are potential targets for drugs. We will study how parasites cause disease and how the host responds to infection.

Summary
In this project the world’s most effective vaccines against diseases caused by parasites will be translated from the laboratory to the clinic. The vaccines prevent transmission of parasites from livestock animals to humans. During the next 5 years the vaccines will be produced on a large scale and evaluated in field trials. The products of this research program will make a major contribution to reducing the number of people suffering from parasitic cysts.
