Summary
Urinary tract infections (UTI) are common infectious diseases in humans. Uropathogenic Escherichia coli (UPEC) cause most UTI. UPEC produce factors that promote their survival and influence disease such as flagella. We have identified anti-inflammatory responses as a key element of UTI and have shown that these responses contribute to control of UTI. In this project, we will investigate how the UPEC flagella component, FliC, contributes to anti-inflammatory responses and what this means for UTI.
Dissecting Immune Responses To Salmonella Infection

Summary
Successful treatment of Salmonella infections requires a detailed understanding how Salmonella growth is controlled. This project will examine the role of white blood cells, will reveal how they contribute to the control of Salmonella infections and will test novel treatment options. The outcome of this project will significantly advance our understanding of immune responses against Salmonella.
Understanding Sperm Motility For Infertility And Contraceptive Purposes

Summary
Male infertility is a significant clinical problem affecting one in twenty Australian men. The most common feature associated with this condition is defects in sperm motility. Regulation of sperm motility occurs through the epididymis and upon ejaculation. This study will examine how two kinases, essential for flagella bending, regulate sperm motility. Through the tools developed, we will investigate further defectives in infertile individuals with impaired sperm motility.
Characterisation Of Novel Cilia Proteins And Roles In Human Disease

Funding Amount
$339,410.00
Summary
Cilia and flagella are tiny hair-like structures attached to the surface of most cells in the body. They perform different roles in many different organs including the brain and play key roles in our sensory systems. This project aims to identify and characterise components of cilia in order to better understand the causes of disorders where the cilia do not function properly.
The Function Of Gametogenenin In Male Fertility And Embryogenesis

Funding Amount
$537,579.00
Summary
We have identified gametogenetin as novel protein involved in sperm production and in the very earliest stages of embryo survival. It is found within the sperm tail where it binds to cysteine-rich secretory protein 2. The aim of this project is to further refine the biochemistry of GGN using a combination of binding studies, expression analyses and the characterization of two unique mouse models. This project has direct relevance to the causes of human infertility and contraceptive development.
