Probing sexual transformation of the human malaria parasite, Plasmodium falciparum, using novel imaging modalities. Malaria parasites adopt a characteristic banana shape prior to sexual recombination; without this shape change disease transmission via mosquitoes cannot occur. This project will use advanced imaging technologies to study sexual recombination of malaria with a view to preventing the millions of deaths due to malaria each year.
Post-genomic investigation of the relict plastid and mitochondrion of malaria parasites. Malaria is a major global health problem. The malaria parasite has two substructures, a relict chloroplast and a mitochondrion, that are excellent targets for new and existing drugs. However, we do not know the key functions of these two compartments. The entire genetic blueprint (genome) is now available for the malaria parasite and I propose to determine exactly which parts of the genome service the rel ....Post-genomic investigation of the relict plastid and mitochondrion of malaria parasites. Malaria is a major global health problem. The malaria parasite has two substructures, a relict chloroplast and a mitochondrion, that are excellent targets for new and existing drugs. However, we do not know the key functions of these two compartments. The entire genetic blueprint (genome) is now available for the malaria parasite and I propose to determine exactly which parts of the genome service the relict chloroplast and mitochondria. This will sketch out a picture of their inner workings. Armed with this information we can take a rational approach to seeking an Achilles? Heel of malaria against which parasite-specific drugs can be developed.Read moreRead less
Investigating why malaria parasites have a unique translocon. This project aims to explore the mechanism that enables malaria parasites to thrive in their host cells. Parasites that cause the disease malaria reside inside erythrocytes, a very basic cell that lacks a vesicular trafficking pathway. To survive and thrive in this environment, the parasite has evolved a completely unique cell biological phenomenon termed PTEX to transport its proteins into the host cell. The aim of this project is to ....Investigating why malaria parasites have a unique translocon. This project aims to explore the mechanism that enables malaria parasites to thrive in their host cells. Parasites that cause the disease malaria reside inside erythrocytes, a very basic cell that lacks a vesicular trafficking pathway. To survive and thrive in this environment, the parasite has evolved a completely unique cell biological phenomenon termed PTEX to transport its proteins into the host cell. The aim of this project is to determine how this novel PTEX machinery exports proteins into erythrocytes and whether PTEX is also required for parasite survival during the initial stages of a host infection when malaria reside in hepatocytes.Read moreRead less
Composition, assembly and functions of the pellicle of apicomplexan parasites: a structure pivotal to disease transmission and progression. Apicomplexan parasites are successful agents of disease (e.g. malaria) due to their superb ability to quickly invade host cells and generate many more parasites. This project will study the dedicated structures beneath the parasite cell covering that are responsible for these abilities to help refine strategies for combating apicomplexan diseases.
