Viral Immunity and Immunopathology

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 innate immune responses during viral infections.

One focus is influenza A virus (IAV), the virus responsible for the ‘flu’. There is a continual threat that novel influenza A viruses IAV will be transmitted from birds to humans, an occurrence called ‘cross-over’. These severe infections involving highly pathogenic IAV are associated with hyperinflammatory responses, immunopathology and high mortality rates (30-40 per cent).

Innate immune responses play an important role in providing protection during viral infections, such as those involving IAV. However, an overreaction of the innate immune system, such as that seen during severe IAV infection, causes cellular and tissue damage. 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 inducing and regulating a hyperinflammatory response in order to identify novel therapeutic targets.
