Amid tough global competition, Melbourne has again confirmed
its position as Australia’s pre-eminent biomedical destination by
securing almost 20% of the prestigious worldwide medical research
awards announced by the US-based Howard Hughes Medical Institute (HHMI).
Eight Melbourne scientists including six from The Walter and Eliza
Hall Institute of Medical Research (WEHI) have today been named HHMI
International Research Scholars. Each scientist will receive a five-year
research grant of between AUD$466,000.00 and $666,000.00.
Nearly 500 scientists from 62 countries applied for the awards, which
were eventually made to 42 scientists in 20 countries - including
the eight in Melbourne, the only Australian city to receive awards apart
from one award shared with Hobart. Among other countries outside the US,
France received six, while Switzerland and Canada received four each.
The HHMI is awarding a total of AUD$23.3 million worldwide to tackle infectious
and parasitic diseases such as malaria, tuberculosis, haemorrhagic fevers
and anthrax. The objective is to stimulate international efforts to understand
the underlying mechanisms of diseases, to help identify potential new drug
targets and to develop vaccines.
In Washington, DC, HHMI President, Thomas R. Cech, says,
“Through its international program, HHMI is supporting scientists of the highest
quality in their home countries. We also bring these international scholars together
with each other and with other scientists in the HHMI community to create an
international network of scientific excellence.”
Malaria expert Professor Alan Cowman, Head of the
Infection and Immunity Division at The Walter and Eliza Hall Institute, says,
“On a world scale, these awards from the HHMI demonstrate the tremendous strength
of basic biomedical research in Melbourne and at WEHI in particular. The funds
granted will accelerate our search for more effective drugs and vaccines for
malaria, which infects and debilitates about 10% of humanity and kills around
2 million people every year.”
Melbourne’s newly-announced HHMI International Research Scholars:
Professor Alan Cowman; WEHI: to investigate how Plasmodium
falciparum, which causes the most lethal form of human malaria, invades mature
red blood cells. This information will be important in determining the potential
of proteins involved in the process as vaccine and drug candidates.
Dr Brendan Crabb; WEHI: to study merozoite surface proteins,
the prime targets of immune responses and the leading vaccine candidates for
control of the deadly malarial parasite, Plasmodium falciparum. Specifically,
his group will use genetic technologies to study the relative importance of
specific merozoite antigens.
Professor Simon Foote; WEHI and the Menzies Research Institute, Hobart:
to determine how the host defends itself against malaria resistance by infecting
genetically similar mice carrying rare mutations and studying the mutations that
allow animals to survive infection. This research will yield insights into host
response to malaria.
Dr Louis Schofield; WEHI: to study the role of innate
immunity and the parasite toxin in susceptibility and resistance to severe
malaria. It is hoped that determining the role of the toxin and innate
responses in disease, and the role of anti-toxin antibodies and counter-regulatory
mechanisms in clinical immunity to malaria, will provide a rational basis for
the development of interventions that prevent malaria fatalities.
Dr William Heath; WEHI: to investigate the effects
of the interaction between malarial parasites and dendritic (antigen-presenting)
cells, which initiate immunity, on the ability of malaria to overcome the
efforts of a competent immune system. He will study which specific types
of dendritic cells capture malaria and how these immune cells are affected
by a fully-fledged infection by Plasmodium falciparum.
Dr Gabrielle Belz; WEHI: to investigate the mechanisms
by which antigen presenting cells induce the body to produce elevated
numbers of CD8+ memory T cells during acute and persistent viral infections.
These memory T cells are vital to long-term protection of the body against
subsequent viral infection.
Professor Geoff McFadden; The University of Melbourne:
to investigate a tiny and vital organelle, the apicoplast, within the malaria
parasite. The aim is to understand how drugs that disrupt the apicoplast work
and how the apicoplast is powered.
Associate Professor Alex Andrianopoulos; The University of Melbourne: to
investigate the human pathogen Penicillium marneffei, a fungus that can grow
in either a unicellular or multicellular form, depending on the temperature
surrounding it; and to determine the genes controlling this change of form
at the molecular and cellular level.
