Summary
Class I cytokine receptors include around 30 receptors with diverse functions such as controlling metabolism and inflammation. Cytokine receptors are molecular switches on cells that receive signals from other cells and transmit this signal into the cell’s nucleus to control the regulation of genes. This project will determine the molecular mechanisms involved in class I cytokine receptors and use this knowledge to develop novel ways to modulate these receptors for clinical applications.
GABA(B) Receptor Modulation Of Gastrointestinal Function In Health And Disease By Alpha-Conotoxins

Summary
Chronic visceral pain is a common and debilitating condition arising from numerous diseases that affect our internal organs. There is a desperate need for more information about the mechanisms responsible for signalling chronic visceral pain to provide therapies and potentially find a cure for it. Our research focuses on ?-conotoxins (small peptides from marine cone snail venom) as novel potential therapeutic agents for the treatment of chronic visceral pain.
Macrophage Polarisation And Control Of Pulmonary Inflammation.

Summary
As key immune cells, macrophages are polarised to phenotypes that turn inflammation on or off. In cystic fibrosis, defective macrophage polarisation enhances inflammation and prevents lung repair. We are defining the molecules and cellular pathways that control this process and identifying targets for existing drugs that can be used to reprogram macrophages and restore lung repair to improve patient outcomes.
Tissue Ferritin Acts As A Proinflammatory Mediator Of Hepatic Fibrosis In Chronic Liver Disease Via Multiple Receptors In Hepatic Stellate Cells Responsible For Both Binding And Signalling.

Funding Amount

Summary
Our research has identified a role for tissue-derived ferritin as a proinflammatory cytokine in hepatic stellate cell biology, the cells responsible for liver scarring (fibrosis) in Haemochromatosis. This proposal will identify the receptor responsible for eliciting ferritin's proinflammatory action and assess its role in fibrosis. This study will have implications in chronic liver diseases of varying aetiologies where elevated serum ferrritin is associated with inflammation.
