Summary
Antibiotic resistance (AR), as highlighted by the WHO, is the most pressing medical need of the 21C – some infections are now untreatable. Our research will focus on the new "superbug" NDM-1 positive E. coli. We will correlate AR and pathogenicity and explore the evolution of these "superbugs" using state-of-the-art sequencing. This research will benefit Australian medicine by predicting timelines of AR epidemics and by conducting the first analyses on the virulence potential of these strains.
Mosquito-borne alphaviruses such as Ross River and chikungunya viruses cause widespread epidemics and exert extreme pressure on the public health systems of affected regions. Alphaviruses spreads to joints and triggers a severe disease in those affected. There are no effective treatments or vaccines. The project will investigate virus-host interaction at the bite site. The outcome will be new knowledge to treat infection at the mosquito bite site to prevent joint disease.
Novel Insights Into The Pathobiology Of Alphavirus Infections

Summary
Infections with mosquito-borne viruses are increasing at an alarming rate worldwide. Ross River virus is endemic in parts of Australia, PNG and Pacific islands, while chikungunya virus is distributed globally and causes recurrent pandemics that involve millions of people. These viruses cause severe musculoskeletal disease for several months after infection. This project aims to establish how these viruses interact with the human host to cause disease and may provide a basis for new treatments.

Summary
Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTI) and sepsis. Recently, a highly virulent clone of UPEC (E. coli ST131) that is resistant to multiple types of antibiotics has emerged and spread worldwide. This project uses genomic and high-throughput functional analysis methods to understand E. coli ST131 virulence and resistance. The outcomes of the work will be a better understanding of how E. coli ST131 causes disease, and potentially new treatment regim ....Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTI) and sepsis.

Identifying Mitochondrial Genome Variants Associated With Familial Migraine Susceptibility

Funding Amount
$443,273.00
Summary
New therapeutic targets for migraine are desperately needed. Although studies have identified some migraine genes there remains considerable underlying genetic variation to be characterised. This study aims to identify functional variants in the mitochondrial genome that contribute to migraine susceptibility, utilising the isolated Norfolk Island population. Outcomes will determine the significance of the variants identified, potentially leading to new diagnostics.
Identifying Novel Gene Mutations For Molecular Diagnosis Of Familial Hemiplegic Migraine

Funding Amount
$623,460.00
Summary
This proposal aims to identify novel FHM genes by undertaking an NGS screen of the whole exome of 209 FHM patient samples. We will test the pathological relevance of detected novel mutations by functional analysis in human cell models and using patient-specific stem cell techniques. Using whole genome NGS technology to identify novel mutations will assist in the design and development of a comprehensive NGS approach to diagnose and differentiate this severe neurological disorder.
High Penetrance Deleterious Mutations In Blinding Glaucoma

Funding Amount
$1,345,055.00
Summary
This project aims to identify the genes most commonly mutated in individuals with advanced glaucoma. Identification of such genes will lead to improved understanding of glaucoma pathogenesis, a better ability to predict risk, and the identification of drug targets for novel therapies.
This study is aimed at identifying genetic variants that influence susceptibility to migraine. We plan to use DNA samples already collected from families with multiple migraine affected individuals and sequence a region on the X chromosome that has previously been identified as harbouring a migraine susceptibility gene. This project will identify gene(s) that contain variants contributing to migraine.
Delayed Radial Glial Maturation Linked To NFI Deficiency As An Underlying Cause Of Cortical Defects In Humans And Mice

Funding Amount

Summary
The timely generation of neurons and glia is important for brain development and consequently brain function throughout life. Nuclear factor I (NFI) genes are important for regulating the production of neurons and glia, and people with disrupted NFI genes have severe cognitive and motor deficits. Using human genetic data and mouse models, we will analyse how disrupting these genes affects brain development, and changes the overall structure and wiring of the cerebral cortex as well as behaviour.
Astroglial Remodelling Of The Interhemispheric Midline Is Regulated By Deleted In Colorectal Cancer (DCC) Signalling And Is Required For Corpus Callosum Formation

Funding Amount

Summary
The integration of information between the brain hemispheres occurs via a large bundle of connecting nerve fibres called the corpus callosum. People with a genetic mutation in DCC display mirror movement disorder and some have a severe brain defect where the corpus callosum fails to form, but at present we don’t understand the function of this gene. In this study we will investigate how DCC functions in early brain development to regulate corpus callosum formation and mirror movement disorder.
