Summary
Movement of molecules within cells by a process known as membrane transport is critical for normal cell function and also exploited by bacteria to promote infection. The pathway that connects the import pathway to the export pathway is essential for the function of a large number of proteins, however this connecting pathway is poorly characterised. This study will define the machinery of this trafficking pathway, which will provide the ability to modulate biological processes and cytotoxicity.

Summary
Neurodegenerative disorders share a similar pathway to disastrous neurotoxicity, which occurs through the release of cytokines such as tumour necrosis factor-a (TNF) from glial cells. TNF controls inflammation but its excessive secretion in the brain is highly detrimental. The mechanism of TNF secretion is unknown but strategies aimed at reducing it have therapeutic potential. This grant proposes to study TNF discharge to find new ways to reduce secretion and confer protection in a stroke model.

Summary
Cytokines or chemical messengers released by cells are essential for controlling immune responses but, in excess, they cause Crohn's disease and arthritis. Our research aims to block cytokine release as a novel way to ameliorate disease. We have identified specific cellular proteins, called golgins, that can be targeted to reduce cytokines. Here, characterization of golgin mediated cytokine transport in cells and in a mouse disease model is necessary to translate these findings for human benefit
