Summary
Injury of the airway epithelium (cells lining the airways) is normally repaired by a process involving the deposition of specific proteins by the airway epithelial cells, promoting them to attach and migrate to cover the injury. These cells appear to be abnormal in asthmatics, in that they fail to repair. By studying specimens from healthy, allergic and asthmatic children we will determine the factors that influence the ability of these cells to repond to an injury in a normal manner specificall ....Injury of the airway epithelium (cells lining the airways) is normally repaired by a process involving the deposition of specific proteins by the airway epithelial cells, promoting them to attach and migrate to cover the injury.

Summary
White blood cells must be able to migrate to fight infection. For instance, immune responses are started by the migration of one type of white blood cells to the lymph node. Also, once activated white blood cells migrate out of the circulation to the site of infection where they can kill bacteria and viruses. This grant studies 2 proteins that control white blood cell migration. These proteins may one day be targets for drugs that either promote immunity or reduce inflammation.
Blood clotting is the underlying cause of heart attacks and strokes. We have discovered that the protein, ERp5, is essential for normal blood clotting. Our preliminary findings indicate that ERp5 controls the function of blood platelets in clotting. Our overall aim is to elucidate how ERp5 regulates platelet function. It is crucial that we understand how ERp5 functions in blood clotting if we are to effectively target it in disease.

Summary
Maintenance of skeletal muscle mass is essential for human health and locomotion. In ageing and cancer, loss of muscle mass leads to severe weakness and immobilization causing morbidity and mortality. This grant aims to characterise a novel gene that when deleted in mice leads to significant muscle damage. The molecular pathways within the cell that lead to the observed muscle damage will be investigated and this may provide insights into the pathways that control muscle damage and its regenerat ....Maintenance of skeletal muscle mass is essential for human health and locomotion.
