The immune system is equipped with an armoury of ways to recognise and kill cancer cells. However, the many checks and balances that regulate detrimental immune responses such as allergies and autoimmune diseases can contribute to immune escape. We are investigating how the immunosuppressive environment in head and neck cancer is maintained, how cells normally associated with allergies participate in this process, and are working on ways to unleash aspects of the granulocytic and allergic inflammatory response to kill solid tumors.
Disease focus: Head and neck cancer
The human body must recognise an array of foreign microorganisms to protect against infection. Airway mucosal tissue is a specialised barrier capable of protecting against infection while allowing airflow into the lungs and absorption of oxygen. Likewise, the skin is the largest barrier tissue in our body and provides both physical and immunological protection from infection. Allergies occur when detrimental immune responses occur in the quest for protection. This can often be against environmental allergens such as pollen or against usually harmless microorganisms. Our laboratory is seeking to understand what causes inflammation and allergies to develop at barrier surfaces and define new treatments for these kinds of diseases.
Viral respiratory infections are associated with development of childhood asthma and barrier dysfunction in latter life, but little is known about how bacterial and viral sensing might program the airway epithelium to potentiate asthma. We are investigating whether exposure to microorganisms including bacteria, fungus and viruses reprogram airway tissue progenitor cells to potentiate inflammatory airway disease.
Disease focus: Chronic rhinosinusitis, Asthma, Eosinophilic granulomatosis with polyangiitia (formerly called Churg-Strauss syndrome), and atopic and autoimmune skin diseases.
