Summary
There is a strong association between allergy and asthma. This association been almost universally assumed to be causative. However, recent evidence suggests an alternative explanation ie., that the abnormal epithelium in asthma allows or facilitates sensitization to airborne allergens. This project will test this alternative hypothesis using human lung tissue and an animal model.

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.

The Molecular Basis For The Initiation Of Squamous Differentiation And How It Is Disrupted In Oral Cancers

Summary
Squamous cancers of the mouth, nose and throat occur due to defects in the cells that line these regions. We have shown that a major defect is that the lining cells are unable to stop growing and mature into cells that provide a barrier against the environment. In this proposal we will undertake studies to identify why these cancers cells do not mature properly. In doing so we will be able to identify new strategies that may be used to treat patients with this frequently deadly cancer.
Fibroblast Senescence As A Driver Of Pulmonary Fibrosis

Summary
Idiopathic pulmonary fibrosis (IPF) has no cure. Currently we think that IPF develops like normal wound healing, but the normal “braking” mechanisms in the myofibroblasts (the cells that produce the connective tissue) don’t work, such that too much connective tissue is produced and oxygen transfer to the blood is stopped. We have identified a protein we think stops, the myofibroblasts from dying. Reducing the activation of this protein should return the myofibroblasts function to normal.
Mechanobiology Of Epithelial Homeostasis In Health And Disease

Summary
Epithelial tissues, such as the lung, fundamentally protect the body from its external environment. For this, they must detect and respond to danger. My work has discovered a new biological system where cells monitor changes in mechanical forces as a sign of danger. Diseases such as inflammation and cancer occur when this detection system fails. This Fellowship builds on my lab’s pioneering work to understand how force is used to sense danger, and how disease occurs when it goes awry.
