Understanding Novel Viral Host Interactions That Modulate Innate Immunity

Summary
Lethal viruses such as coronaviruses (MERS, SARS-CoV-1, SARS-CoV-2), Dengue, Zika, Hendra, and Nipah have developed effective mechanisms of replication by dampening the host immune system. Here we will examine how viruses carry out these immune evasion functions, and test antiviral drugs that can prevent these effects in a highly specific manner. If this idea can be proved, it will provide great promise for the development of new antivirals whilst minimising the toxic effects to the cell.
Understanding The Role Of Lipid In Membrane Permeabilization By The Bcl-2 Family Executioner Proteins

Funding Amount
$626,524.00
Summary
Apoptosis is a form of programmed cell death that protects our bodies from dangerous cells, e.g cells infected with viruses or that might become cancerous. A network of protein families control this process and this work will understand how certain members regulate a crucial step in this cell death pathway. Our studies will reveal key insights into apoptosis at the molecular level and inform the development of therapeutics for diseases characterised by dysregulated cell death such as cancer.
Host-virus Protein Complexes In The Immune System Response To Influenza

Funding Amount
$316,449.00
Summary
This proposal will investigate the inhibition of the human immune response by viruses. Specifically, an enzyme, TRIM25, which ubiquitinates proteins important for signalling the viral immune response has recently been shown to be inhibited by the non-structural influenza protein NS1. The mechanism of this inhibition is unknown and is thus the subject of this project.
Engineering CYP17A1 Inhibitors For Castrate-resistant Prostate Cancer

Funding Amount
$519,428.00
Summary
As prostate cancer progresses it becomes resistant to first line treatments and the current second line treatments have untoward side effects. This proposal will provide proof of principal for new selective drugs to be developed. We propose an innovative strategy to develop new selective drugs for the treatment of prostate cancer. This new therapeutic approach will identify new compounds for patients specifically with castrate sensitive and resistant prostate cancer.
Peripheral Membrane Proteins In Health And Disease

Funding Amount
$640,210.00
Summary
Peripheral membrane proteins are critical for processes such as cell transport, signaling, neurosecretion and development. As such, their dysfunction can lead to many debilitating diseases including cancer, inflammation and neurodegeneration. This project will establish fundamental new knowledge about how peripheral membrane proteins regulate cell function, how their perturbation or mutation results in human disease, and will inform efforts to target them for future therapeutic outcomes.
Structural Studies On The Conjugative Apparatus Of The Gram-positive Bacteria, Clostridium Perfringens.

Funding Amount
$287,321.00
Summary
Antibiotic resistance is a worldwide health problem. It has severely reduced the effectiveness of many antibiotics driving up the health care costs and death rates associated with bacterial infections. This project aims to investigate how antibiotic resistance determinants are transferred in the pathogenic bacteria, Clostridium perfringens. By understanding the mechanism of antibiotic resistance transfer in bacteria we will be better armed to combat antibiotic resistance.
