A Novel Role For Proteolysis In Promoting Inner Ear Cell Injury And Hearing Loss

Summary
Nearly 40% of hearing loss is attributable to traumatic noise exposure. This project will test a new idea that cells in the inner ear are damaged and die via noise-induced proteolysis, and investigate whether a similar mechanism operates during age-related hearing loss. It will open new avenues for therapies to preserve hearing where trauma is unavoidable, or has occurred through accident or incident.
Targeting Neuroserpin-plasmin Interactions To Protect The Retina In Glaucoma

Summary
Glaucoma causes blindness and despite our best treatment many patients continue to progress. A new approach is needed to protect the cells that die in the retina. We have established that a common protease – plasmin – is involved in the process, and a protein that normally regulates it – neuroserpin – is downregulated in the disease. We aim to modify neuroserpin using an ocular gene therapy approach and show it could be used as a novel therapy in glaucoma.

Summary
Traumatic brain injury (TBI) is a significant cause of mortality and morbidity in Australia, affecting approximately 21,800 Australians annually. A large number of survivors have permanent neurological deficits, causing adverse effects on lifestyle and family relationships and placing a significant burden on the health system. In this project we will address a novel means to improve TBI outcome by targeting two linked enzyme systems that together have been shown to be deleterious in this conditi ....Traumatic brain injury (TBI) is a significant cause of mortality and morbidity in Australia, affecting approximately 21,800 Australians annually.

Regulation Of Inflammation And Coagulation By Microparticles Containing SerpinB2

Summary
SerpinB2 is a protein that is abundant during many types of inflammation. However, what this protein actually does remains an enigma. We have found that SerpinB2 is associated with microparticles; small particles found in everyone’s blood, that are used by cells to communicate with each other. We believe inappropriate levels of SerpinB2 on these microparticles change both inflammation and blood clotting; a contention with implications for several diseases including pre-eclampsia and cancer.
Investigating The Role Of SERPINB6 In Cochlear Function And Deafness

Summary
In 2010 a novel genetic mutation was identified that causes progressive hearing loss in humans, however, it was not established why this mutation leads to the disease. We propose that the mutation renders cells of the inner ear more susceptible to death caused by noise trauma. We will investigate this in a mouse model of the human condition. This could lead to the development of therapies that prevent hearing loss.
