Identification and development of novel vaccine candidates for malaria

Funded Activity Summary

The aim is to improve methods of preventing and treating malaria by understanding the basic biological mechanisms the pathogen that causes the most severe form of human malaria, uses to invade and survive in the host erythrocyte, and survives in the hostile environment of the blood, as this determines disease outcome. I have outlined an ambitious program for the next five years that will utilize our basic knowledge of how this parasite infects and causes disease to identify novel vaccine candidates from the genome of P. falciparum. This represents a major task that will not only provide new information for the malaria field but also identify the most promising candidates that will be pursued into clinical development. I will use two strategies; firstly, a consortium will be formed that brings together expertise that will credential the P. falciparum genome. This provides our experience in functional genomics with EHIME University who have developed methods to express correctly folded P. falciparum proteins in a high throughput system using wheat germ in vitro translation and University of Pennsylvania who have expertise in bioinformatics of the malaria genome. It provides the critical mass and expertise required for a major project. We have developed novel methods for expression of protein domains on the surface of the P. falciparum-infected erythrocyte and this has important utility for analysis of function and immune responses to these proteins. To utilize and develop these tools I will build a critical mass of expertise by forming a consortium between Australian scientists together with Papua New Guinea Institute of Medical Research, KEMRI Institute for Geographic Medicine (Kenya), Harvard University and the Swiss Tropical Institute (Switzerland). This consortium will provide access to malaria endemic areas and the expertise in fieldwork and epidemiology to fully utilize the parasite lines we will construct. The formation of these consortia will greatly strengthen our ability to identify the most promising candidates for clinical development. This will also have great benefit to Australia by increasing the internationalization of our science and therefore access of our researchers to other expertise and also provides a means for networking outside of this country. To foster and increase our leadership in malaria I will develop a Functional Genomics facility that will provide the capacity to construct large panels of transgenic parasites and the ability to develop new genetic tools. Additionally, I will develop a specialized microscopy facility at WEHI to provide the advanced equipment required for visualizing molecular events in live cells. This facility will include a number of instruments including a Line scanner confocal that will be essential for following cellular events such as protein trafficking in live parasite lines.
