Summary
If successful, our approach will potentially have a major impact on the treatment of diabetic retinopathy and possibly on all diabetic vascular diseases. A single injection might only be necessary to prevent the development of diabetic retinopathy, which would represent a significant weapon in the management of patients. In addition, successful application of secretion gene therapy in the eye might open up the possibility to introduce the same concept for the treatment of larger organs undergoin ....If successful, our approach will potentially have a major impact on the treatment of diabetic retinopathy and possibly on all diabetic vascular diseases. A single injection might only be necessary to prevent the development of diabetic retinopathy, which would represent a significant weapon in the management of patients. In addition, successful application of secretion gene therapy in the eye might open up the possibility to introduce the same concept for the treatment of larger organs undergoing microvascular changes as a result of diabetes.Read moreRead less
Abnormal growth of blood vessels is a central feature of number of blinding conditions of the eye. Although there are treatments available that reduce the sudden loos of vision in a majority of people with advanced age related macular degeneration, about 20% fail to respond and half gradually loose vision. This project will determine the effectiveness of treating vascular diseases of the retina with a novel therapy that is quite different to that currently available.
Dynamic Trafficking Of Amino Acid Transporters At Synapses And Their Role In Regulating Neurotransmission

Summary
Brain cells release chemical neurotransmitters to activate their neighbours. The most abundant neurotransmitter is glutamate, which mediates most of the communication in the brain. Following release, this neurotransmitter must be rapidly recycled to prevent levels being depleted and neurotransmission failing. The subject of this grant is to understand what molecules and pathways are used to recycle glutamate in the brain, and how its supply is controlled to sustain continual brain activation.
Improving Bionic Device Safety And Performance With Conductive Hydrogels

Summary
Bionic devices are being developed to treat a variety of neural disorders including blindness. Conductive hydrogels (CHs) are a new soft material developed by the CI to improve device performance and safety. This project will explore CH technologies with an aim of producing flexible organic electronics for high resolution devices, such as the bionic eye. Collaboration will be sought through industry, academia and clinical researchers to accelerate technology translation from bench to bedside.
Astroglial Remodelling Of The Interhemispheric Midline Is Regulated By Deleted In Colorectal Cancer (DCC) Signalling And Is Required For Corpus Callosum Formation

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.
Nfi Genes Regulate The Switch Between Neurogenesis And Gliogenesis During Cortical Development

Summary
Cells within the brain fall into two categories; neurons or glia. Importantly, both derive from a common progenitor population, the radial glia, during development. Early in development radial glia produce neurons, while later they generate glia. The genes which control the switch from neuron production to glia production remain poorly defined. I propose to investigate how this switch is controlled in radial glia, focussing on a family of proteins known to regulate gene transcription.
