Summary
Cough is the most prevalent symptom of lung disease and the most common reason for people to seek medical advice. However, cough neural processes are poorly defined and as a result current cough therapies are largely ineffective making cough a significant unmet clinical problem. This project will novel viral strategies to dissect and manipulate cough neural pathways in the brain, providing insights into the neural processing of airway sensations and coughing.
Understanding The Role Of Caudal Auditory Belt Areas In Perception Of Complex Sounds

Summary
Although the auditory cortex is key to our understanding of several neurological conditions, including language impairments, the functions of many of its areas are still unknown. Using an animal model, we will examine the roles of different auditory areas in separating important sounds from noise. This is a critical role in coordinating our body’s responses to acoustic stimuli. This study will help clarify how these areas contribute to how we normally process sounds, and what deficits are likely ....Although the auditory cortex is key to our understanding of several neurological conditions, including language impairments, the functions of many of its areas are still unknown.

Role Of Macrophages In Uropathogenic E. Coli Infections

Funding Amount
$574,890.00
Summary
Urinary tract infections (UTI) are one of the most common types of infections in humans. They are also a major cause of septic shock, a condition with high fatality rates. Uropathogenic Escherichia coli (UPEC) are the major microbes causing UTI in humans. This project addresses the role of an immune cell type, the macrophage, in UPEC-mediated disease. The outcomes of this project will be a better understanding of how UPEC causes disease, and potentially new treatment regimes for UTI.
Organization Of Descending Auditory Projections From Inferior Colliculus To Cochlear Nucleus

Summary
Sensory information gains awareness by ascending brain pathways to reach consciousness. Descending projections, however, have grown in importance because of implications for feedback management of ascending signals. Studies of these pathways will provide insight into auditory processing with respect to selective volume control, calibration adjustments between the two ears, and the extraction of signals from background noise. The data could lead to new strategies for treating hearing disorders.
Extending The MIS BAIR Randomised Trial Of BCG To Prevent Childhood Allergy And Infection

Funding Amount
$939,504.00
Summary
BCG (used till recently to prevent tuberculosis) is a potential low cost and readily available vaccine which could reduce the rates of allergy and infection in Australian children. We propose to extend our existing NHMRC-funded trial, which studies whether BCG vaccinatinon given at birth prevents the development food allergy, eczema and infection in the 1st year of life, to see if this effect continues until 5yrs of age. At this age, we can also see if BCG vaccination at birth prevents asthma.
Priming, Recruitment And Retention Of Influenza Virus Specific CD8 T Cells In The Upper Airways

Funding Amount
$633,371.00
Summary
Influenza virus gains entry into the body by inhalation and initiates its replication cycle within the upper airways. This early stage of infection, when the amount of influenza virus is low, provides the ideal window of opportunity for an effective immune response to limit disease progression. In this proposal we will define the immunity that can be evoked within the upper airways and determine immune mechanisms left behind that can safeguard this region from this important respiratory pathogen
A Matter Of Life And Death: Defining Novel Interactions Between Uropathogenic E. Coli And Macrophages That Influence UTI Pathology

Funding Amount
$643,060.00
Summary
Urinary tract infections (UTI) are one of the most common types of infections in humans. Uropathogenic Escherichia coli (UPEC) are the major microbes causing UTI in humans. This project will define novel interactions between UPEC and macrophages, an important immune cell involved in the control of UTI. The outcomes of this project will be a better understanding of how UPEC causes disease, and potentially new treatment regimes for UTI.
The Dual-edged Sword Of Zinc As An Innate Immune Antimicrobial Weapon Against Uropathogenic E. Coli
Funder
National Health and Medical Research Council
Funding Amount
$784,428.00
Summary
Infectious diseases are a major global health threat, and urinary tract infections (UTI) are one of the most common infectious diseases. Most UTI are caused by uropathogenic E. coli (UPEC). In order to cause infections, UPEC must be able to overcome our body’s first line of defence, the innate immune system. This project seeks to understand how our innate immune system uses zinc to combat bacterial infections, and how UPEC is able to defend against such responses in order to cause disease.
Understanding Uropathogenic E. Coli-mediated Subversion Of Innate Immunity

Funding Amount
$932,536.00
Summary
Urinary Tract Infections (UTI) are one of the most common bacterial infections. Uropathogenic E. coli (UPEC) are the primary cause of UTI and increasingly associated with antibiotic resistance. UPEC use an array of strategies to overcome the innate immune system, which provides the first line of defence against infectious diseases. This project aims to understand how UPEC overcomes innate immunity, with the ultimate goal of devising new approaches for the treatment and prevention of UTI.
The Current Multidrug Resistant Escherichia Coli Pandemic: Exploring Novel Therapies Against The Predominant Culprit E. Coli ST131.
Funder

Funding Amount
$512,223.00
Summary
Escherichia coli ST131 is a pandemic superbug. Like MRSA, E. coli ST131 infections are resistant to multiple antibiotics and can become life threatening. This study will show how adhesion can be the 'Achilles' heel' of this global pathogen and how blocking E. coli ST131 adhesion offers an alternative therapy for multidrug resistant human infections. As we are left with no effective antimicrobials to treat E. coli ST131 infections, this work will provide novel outcomes that are sorely needed.
