Targeting NPY Mechanisms In Rodent Models Of Generalised Epilepsy
Funder

Funding Amount
$437,637.00
Summary
This project will provide important information regarding the pharmacological mechanisms by which NPY acts to suppress seizures in animal models of epilepsy. It will provide strategies regarding potential new treatments of absence epilepsy.
We will use genetically engineered mice to study brain circuitry in an effort to understand the anatomical basis of Huntington's disease and a number of other more common degenerative brain diseases similar to Parkinson's disease. We will look at the brain in detail to decipher how the injured brain repais itself by making new connections and by producing new cells. We will also study supporting cells in the brain to determine if they play a beneficial role in this injury repair process.

Summary
Motion is an everday visual experience, and in this project we are attempting to explain how our brains are able to detect the direction in which an object is moving. Surprisingly this is first accomplished within the retina, the light-sensitive system of neurons at the back of the eye. Thus the eyes are able to tell the brain in which direction an object is moving. So the question becomes, how do the eyes do it? We know that there is a special class of neurons, the direction-selective ganglion ....Motion is an everday visual experience, and in this project we are attempting to explain how our brains are able to detect the direction in which an object is moving. Surprisingly this is first accomplished within the retina, the light-sensitive system of neurons at the back of the eye. Thus the eyes are able to tell the brain in which direction an object is moving. So the question becomes, how do the eyes do it? We know that there is a special class of neurons, the direction-selective ganglion cells, which are able to detect the direction of image motion. The activity of these cells is increased by excitatory connections and reduced by so-called inhibitory connections. This project aims to identify the neural origin of the inhibitory connections, and discover how the excitation and inhibition work together to compute the direction of motion.Read moreRead less
Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS rese ....Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS research including epidemiology, immunology and neurobiology. Collaboration of 8 major Australian institutions is also important for this project and future studies. The team will have access to a new national MS GeneBank (platform) with samples from 2240 patients that should generate findings important to world-wide MS genetic knowledge.Read moreRead less
The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themse ....The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themselves and information that could help in the development of new and more effective drugs, and biomarkers to assist in the prediction of prognosis. Such advances would decrease the economic impact of these diseases and improve quality of life for those affected.Read moreRead less
New tools to activate and silence neural circuits. Many neurological disorders occur as a result of neuron cell death that is initiated by excessive levels of excitatory activity in central nervous system neurons. This project will develop and validate a new treatment for these disorders that involves silencing excessive neuronal activity using a safe, commonly prescribed drug.
Brain sodium channel: functional role of developmentally regulated alternative splicing. This project will identify the roles of neonatal and adult forms of a sodium channel in the function of neurons in the developing brain. Sodium channels are vital for brain function and this study will improve our understanding of the function of healthy brain as well as of underlying mechanisms of some neurological disorders.
