Understanding the neuronal mechanisms underlying inherited epilepsies. Epilepsy is a serious disease that impacts severely on individuals and the community as a whole. Conservative estimates suggest a financial cost of more than $2 billion per annum. Drug treatment for this disease is often not adequate. Recent advances have allowed scientists to determine mutation in human genes that cause epilepsy. New models of epilepsy based on this knowledge will allow us to better understand what causes e ....Understanding the neuronal mechanisms underlying inherited epilepsies. Epilepsy is a serious disease that impacts severely on individuals and the community as a whole. Conservative estimates suggest a financial cost of more than $2 billion per annum. Drug treatment for this disease is often not adequate. Recent advances have allowed scientists to determine mutation in human genes that cause epilepsy. New models of epilepsy based on this knowledge will allow us to better understand what causes epilepsy enabling us to devise new and potent therapeutic strategies to treat the disease.Read moreRead less
Neurons isolated from embryonic stem cells as functional models for drug discovery. By using gene expression-based selection criteria embryonic stem cells can be driven to differentiate into specific neuronal lineages which show many of the morphological characteristics and immunocytochemical features of neurons in culture. There is, however, comparatively little evidence indicating that these stem cell-derived neurons actually behave as neurons. Our aim is to characterise and contrast four ne ....Neurons isolated from embryonic stem cells as functional models for drug discovery. By using gene expression-based selection criteria embryonic stem cells can be driven to differentiate into specific neuronal lineages which show many of the morphological characteristics and immunocytochemical features of neurons in culture. There is, however, comparatively little evidence indicating that these stem cell-derived neurons actually behave as neurons. Our aim is to characterise and contrast four neuronal cell cultures established with gene-based selection criteria. These cultures will be characterised by gene expression, immunocytochemistry, radiolabelled neurotransmitter release, electrophysiology and Ca2+ imaging studies. This study will highlight the functional effects of gene selection procedures upon stem cell-derived neurons.Read moreRead less
