Summary
Malaria is one of the world's most devastating infectious diseases and is caused by a parasite called Plasmodium falciparum. AMA1 is a parasite surface protein crucial for blood cell invasion but how it works is not understood. We are investigating if AMA1 plays a role in helping the parasite sense when it has contacted a blood cell and should invade. Discovering how parasites attach to and invade bloods cells is a priority for the development of anti-parasite drugs and vaccines

Summary
Significant gains have been made in the past decade in reducing falciparum malaria morbidity and mortality using artemisinin-base combination therapy (ACT) and insecticidal nets. However the recent emergence of artemisinin resistance threatens these achievements. This project will develop and use a mathematical model of malaria transmission incorporating resistance to the drugs in ACTs to investigate the probability and rate of spread of resistance into new areas endemic for malaria.
We will investigate malaria, a parasitic disease that kills over 630,000 people a year. We will explore the function of proteins responsible for cleaving and activating a cascade of proteins important in infection of humans and transmission of the parasite to mosquitoes. We will characterize the proteins involved in these critical events, as they are potential targets for drugs.

Malaria is one of the biggest scourges of mankind. This project aims to translate the available genomic data into functional insights using frontier technology to identify new intervention targets for P. falciparum infection. Developing novel targets against malaria is important from a humanitarian point of view, and also to safeguard Australia and its neighbouring regions against the social and economical implication of this disease. The malaria parasite seeks shelter from the host immune system by hiding in red blood cells, but at the same time it has to stay in contact with the blood environment. This is achieved by export of virulence factors onto the surface of malaria parasite-infected red blood cells, which are essential for the maintenance of malaria infection. Without these virulence factors the body's immune system can get rid of the malaria parasites by itself. For display on the surface the proteins have to pass several membranes and are transferred through the red blood cell. The whole transport and assembly process of the virulence factors into functional units is very complex and requires several helper and co-helper molecules. With the deciphering of the malarial genetic code it became obvious that the parasite displays an unusual large number of co-helper molecules, which are putatively exported into the red blood cell. We will generate transgenic parasites deficient in the expression of these exported co-helper proteins and assess their role on the pathogenesis of this debilitating infectious disease.Read moreRead less
Dissecting The Molecular Basis Of The Malaria Parasite-Erythrocyte Tight Junction Complex

Summary
The parasites that cause malaria disease must invade the human red blood cell to complete their lifecycle. Invasion requires the formation of a complex interface between parasite and red cell called the Tight Junction. However, this structure's molecular makeup is entirely unknown. Our research will use a combination of state-of-the-art microscopy and genetics to define, for the first time, the junction's organization, providing a critical platform for the development of a malaria vaccine.
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.
