Viral Immunity and Immunopathology Research Group
Research Group Head
The Viral Immunity and Immunopathology group focuses on understanding the mechanisms involved in the induction and regulation of inflammation during severe and fatal viral infections and develop life-saving therapies.
One focus is influenza A virus, the virus responsible for the ‘flu’. There is a continual threat that novel influenza viruses will emerge in humans with devastating consequences for global health and the economy. Highly pathogenic influenza viruses currently circulate in wild birds and sporadic infections of humans do occur with high mortality rates of 40-60%. Experts predict a future ‘bird flu’ pandemic is inevitable and without effective drugs we are currently ill-prepared.
Our immune system plays a critical role in limiting and resolving viral infections. However, excessive inflammation elicited during severe viral infections leads to the development of life-threatening disease. Patients often present to hospital with severe disease, several days after the onset of symptoms. There are currently no effective or targeted drugs or therapies in use to limit immunopathology and disease at this stage of the infection.
Utilising a range of preclinical models and techniques, Associate Professor Tate and her team aim to gain a greater understanding of the mechanisms involved in the induction and regulation of a hyperinflammatory response and identify novel therapeutic targets and treatment strategies that limit hyperinflammation. Critically, through strong and productive collaborations with industry we endeavour to bring our discoveries to the clinic.
