Summary
The pancreas is the major digestive organ in the body. It is located in the abdomen, draped across the spine behind the stomach. Pancreatic cancer is a leading cause of death in this country and in Western Society in general. Most patients with this disease survive only a few months after diagnosis. Even for those in whom a curative operation is undertaken, survival is poor. Chemotherapy and radiotherapy (alone and in combination) result in, at best, limited benefit. Clearly, there is a need for ....The pancreas is the major digestive organ in the body. It is located in the abdomen, draped across the spine behind the stomach. Pancreatic cancer is a leading cause of death in this country and in Western Society in general. Most patients with this disease survive only a few months after diagnosis. Even for those in whom a curative operation is undertaken, survival is poor. Chemotherapy and radiotherapy (alone and in combination) result in, at best, limited benefit. Clearly, there is a need for novel approaches to this lethal disease. The proposed project involves an examination of the local tissue reaction around pancreatic cancer. This tissue reaction is usually prominent and the cells involved may determine the extent of local and distant spread of the cancer. Modulation of this tissue reaction may limit pancreatic cancer growth and thus improve outcome.Read moreRead less
Allergen-sensitzation And Environmental Exposures In Early Life Interact Synergistically To Alter Lung Growth

Summary
Asthma develops as the result of complex interactions between genetic susceptibilities and environmental exposures. Approximately 40% of 6-year-old children in Perth are sensitized to inhaled allergens, however, only half of these have asthma. Allergic sensitization per se is therefore insufficient for the development of persistent asthma. A second hit, associated with lung inflammation in early life, increases this risk several fold. This second hit could come from viral infection or from other ....Asthma develops as the result of complex interactions between genetic susceptibilities and environmental exposures. Approximately 40% of 6-year-old children in Perth are sensitized to inhaled allergens, however, only half of these have asthma. Allergic sensitization per se is therefore insufficient for the development of persistent asthma. A second hit, associated with lung inflammation in early life, increases this risk several fold. This second hit could come from viral infection or from other inflammatory stimuli such as exposure to cigarette smoke, air pollutants and vehicle exhaust emissions. The timing of this second hit may well be important, particularly if it is early while the lungs are still growing and developing. The aim of this project is to examine interactions between allergen sensitization and exposure to environmental hazards in early life using a mouse model of allergic inflammation. We will test the hypothesis that the combination of allergic sensitization and viral infections in early life alter lung growth, airway function and airway hyperresponsiveness, however, exposure to air pollutants can not provide the 'second hit required to induce persistent asthma. Determining the role viral infection and environmental pollution have early in life may provide us with a strategy for intervention that could prevent life-long changes in respiratory function and airway hyperresponsiveness.Read moreRead less
