Genome-wide Association Studies To Identify Major Genetic Determinants Of 5 Blinding Eye Diseases Using Pooled DNA

Funding Amount
$562,193.00
Summary
This project aims to find important genes for 5 diseases that can lead to blindness. We will use a cost-effective approach where samples from a large number of individuals with a given disorder are pooled (mixed together) and then compared on gene chips covering the whole genome to a pool of people who do not have the disease. Differences identified between the groups will point to genes causing that disease. We will identify any major genes for the 5 diseases being studied.
Mechanisms Of Novel TLR9 Mediated Intraocular Inflammation

Summary
Corneal opacities and scarring due to microbial and parasitic infections are a major cause of blindness globally. Novel studies in our lab have shown that topical application of bacterial/viral DNA alone to the cornea can cause previously unrecognised inflammation in the retina. Understanding the mechanisms of this retinal inflammation and how to block it may help in the design of novel treatments for a number of blinding conditions.
Making Sense Of Novel Ocular Neuroimmune Interactions.

Summary
It is becoming clear that the interaction between corneal nerves and immune cells underpin many inflammatory conditions of the ocular surface. Despite this increased interest, very little is known about the relationship between corneal nerves and immune cells in this outermost layer of the eye. This project will investigate the relationship between corneal nerves and immune cells during health and corneal inflammation to identify therapeutic targets to treat corneal disease.
Mapping The Dynamics Of Corneal Stem Cell During Aging And After Wounding And Transplantation

Summary
Restoring vision in patients with corneal blindness is our focus. Before this can be achieved we need to understand how corneal stem cells function. For many reasons these studies cannot be performed in man, so we engineered a mouse in which the location, migration, division, differentiation, death of these cells can be followed indefinitely. This information will allow us to improve current therapeutic options and develop new clinical solution for patients with blinding corneal disease.
Gene Identification For Keratoconus - A Blinding Eye Disease

Funding Amount
$912,880.00
Summary
Keratoconus is a common eye disease where the cornea at the front of the eye progressively becomes thinner and bulges out, resulting in severe visual impairment in young people. This project is investigating the genetic causes of keratoconus in a large collection of Australian patients. We aim to be better able to predict who will develop the disease and treat them earlier, as well as be able to target treatments to the causes of disease.
Cultivated Corneal Endothelial Cell Implants For Restoring Vision

Summary
Thousands of Australians each year receive a corneal tissue transplant from the eyes of a deceased organ donor. In the majority of cases these transplants are performed to restore structure and function to the most posterior layer of the cornea – the corneal endothelium. The reliance upon donor tissue, however, presents significant logistical and safety issues. Our goal is therefore to develop improved strategies for treating diseases of the corneal endothelium using cultivated tissue implants.
A Novel Mesenchymal Stromal Cell And Biomaterial For Corneal Reconstruction

Funding Amount
$508,611.00
Summary
Our research group has identified a new cell type (L-MSC) with the potential to treat a variety of eye diseases. We have also developed a novel material from a protein found in silk, that has potential as a vehicle for delivering healthy cells into diseased eyes. The present project will build upon these promising results by evaluating the properties of L-MSC necessary for clinical use and by testing the feasibility of our new cell delivery system.
Anti-vascular Endothelial Growth Factor-B As A Biologic For Treating Eye Disease

Funding Amount
$464,295.00
Summary
We plan to show that an engineered antibody fragment against vascular endothelial growth factor-B is an effective therapeutic drug for two eye diseases, corneal neovascularization and age-related macular degeneration. The innovative aspects of this approach are that it may be safer, and have a different spectrum of activity, than existing ophthalmic anti-angiogenic agents. Furthermore, it may be effective for corneal disease when administered as an eye-drop.
