Summary
Neurotrophic factors are potent proteins that have the ability to keep nerves alive. They have therefore been used in clinical trials to treat motor neuron disease, but without success. A major reason for this appears to be the way in which the neurotrophic factors are delivered. Direct injections into the blood stream are a convenient way of getting these large proteins into the bloodstream, but this is not their normal mode of action. These proteins are normally provided by cells adjacent to t ....Neurotrophic factors are potent proteins that have the ability to keep nerves alive. They have therefore been used in clinical trials to treat motor neuron disease, but without success. A major reason for this appears to be the way in which the neurotrophic factors are delivered. Direct injections into the blood stream are a convenient way of getting these large proteins into the bloodstream, but this is not their normal mode of action. These proteins are normally provided by cells adjacent to the nerves. We have designed a system that more closely resembles this physiological mode of action which involves the delivery of neurotrophic factor genes, via the bloodstream, to the affected nerves. Once inside the nerves the factors are produced on site and, following their secretion, act locally and directly on the injured nerves.Read moreRead less

Summary
Neurotrophic factors are powerful agents found in very low amounts throughout the nervous system. Their role is to keep nerves alive, to assist in connecting nerves together and to help maintain the health of nerves. Usually this is achieved by each factor being bound at the end of the long nerve processes and transported back to the nucleus to regulate the metabolism of the nerve. We have discovered one factor, the protein Brain Derived Neurotrophic Factor or BDNF, in one nerve type which is tr ....Neurotrophic factors are powerful agents found in very low amounts throughout the nervous system. Their role is to keep nerves alive, to assist in connecting nerves together and to help maintain the health of nerves. Usually this is achieved by each factor being bound at the end of the long nerve processes and transported back to the nucleus to regulate the metabolism of the nerve. We have discovered one factor, the protein Brain Derived Neurotrophic Factor or BDNF, in one nerve type which is transported in the opposite direction. The project outlined plans to demonstrate the function of this unique transport by showing how BDNF can be released from nerves to act on neighboring cells.Read moreRead less
Effects Of Muscle Inflammation On Sensory Neuron Excitability

Summary
Muscle pain is a common and poorly treated health problem for many Australians. This project examines the properties of nerves that sense muscle pain and looks at how these change during inflammation, a common cause of muscle pain. We are looking specifically at jaw muscles, which are one of the most common sites of chronic muscle pain. By understanding how muscle nerves are changed by injury, we hope to be able to develop treatments to prevent or reverse these changes.
