Plasmodium vivax is a parasite that invades the youngest of human red blood cells. Our work will reveal how this malaria parasite enters our blood cells and the molecular mechanisms that allows successful invasion. This proposal will redefine our understanding of P. vivax invasion and explore novel ways to block its entry into red blood cells and therefore prevent malaria infection.
Combating Infectious Diseases By Harnessing Macrophage Functions

Summary
Infectious diseases present a persistent global health threat. For patients with life-threatening diseases caused by bacterial pathogens, antibiotics provide the last resort. Antibiotic resistance, even for newly developed antibiotics, is widespread within the bacterial community. New strategies are urgently needed to combat most bacterial infections. This proposal will investigate a new strategy to train and boost our immune systems to combat infectious diseases.
How Does ROCK ‘education’ Of Fibroblasts Drive Neoplastic Progression In The Breast?

Summary
The spread of cancer from one part of the body to another (metastasis) is the main cause of cancer-related death. Metastasis is assisted by the abnormal behaviour of a population of cells called cancer-associated fibroblasts (CAFs). We have identified that activation of an enzyme called ROCK in breast cancers causes an increase in the number of CAFs. We plan to find out how ROCK activation causes this increase in CAFs and find new targets against which breast cancer therapies can be developed.

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.
Functional Analysis Of The Toxoplasma Myosin Driving Tissue Dissemination And Host Cell Invasion

Summary
The single-celled parasite Toxoplasma gondii is the cause of Toxoplasmosis and is an important basis of eye disease, congenital birth defects and illness in immunocompromised individuals. To perpetuate infection T. gondii moves through tissue and invades host cells using a molecular motor, termed the 'glideosome'. We will reveal how the glideosome produces the force required for movement and characterise its critical features. Our work will provide a foundation in which to model novel drugs that ....The single-celled parasite Toxoplasma gondii is the cause of Toxoplasmosis and is an important basis of eye disease, congenital birth defects and illness in immunocompromised individuals.

Nasal Epithelium As A Portal Of Entry For Burkholderia Pseudomallei, With Special Reference To Neurological Melioidosis

Summary
Melioidosis is a potentially fatal disease of manly tropical Australia and SE Asia and an emerging disease worldwide. It disproportionately affects indigenous Australians. It is caused by a bacterium found in soil and water and infection may be by inhalation in the rainy season. One manifestation of melioidosis is neurological symptoms. This project seeks to establish sites and pathways of infection resulting from inhalation, including the pathway from nasal mucosa to brain.
Characterising The Tumour Suppressive Function Of Myoepithelial Cell Stefin A In Ductal Carcinoma In Situ

Summary
Ductal carcinoma in situ (DCIS) is a pre-invasive stage of breast cancer, whereby the tumour cells remain restrained by myoepithelial cells that surround breast ducts. Predicting which cases of DCIS will later develop invasive cancer is difficult, meaning that the majority of patients have treatment. Stefin A is a protease inhibitor in myoepithelial cells shown to block cancer invasion and we aim to test the function of this protein in DCIS and its potential as a prognostic marker.
The placenta is essential for fetal-maternal exchange and healthy pregnancy however the factors that are required for the placenta to form are poorly understood. We will investigate how the placenta develops in mice and which are the most important factors that are required for a health placenta to form.
Colorectal Cancer Membrane Protein Interactomics [A Major Discriminator Of Clinical Outcome]

Funding Amount
$643,778.00
Summary
This project studies the molecular causes of colorectal cancer (CRC) malignancy because CRC is the 2nd most common malignancy by incidence and cause of death in the Western world. It currently results in 13.1% of Australian cancer deaths. The aim of this NHMRC project is to gain a detailed understanding of how particular cell membrane proteins interact with each to give cancer cells the ability to invade and spread.
Defining The Role Of Microphthalmia-associated Transcription Factor (MITF) In Melanoma Heterogeneity By Real-time Cell Cycle Imaging

Summary
Metastatic melanoma is highly therapy-resistant. Modern targeted therapy is promising but suffers from rapid onset of drug resistance. Tumours consist of zones of fast growing cells next to zones of dormant cells. This tumour heterogeneity is one of the reasons for cancer drug resistance, as cells in different growth states respond differently to drugs. By understanding the causes of tumour heterogeneity we will set the basis for innovative clinical approaches against this devastating disease.
