    • Identifying cell-surface attachment factors and entry receptors for respiratory viruses

      In addition to influenza A virus (IAV), members of the Paramyxoviridae family cause significant respiratory disease in humans. These include mumps virus (MuV), human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) and parainfluenza viruses (PIV). Many respiratory viruses use cell-surface glycans (such as sialic acid and glycosaminoglycans) as attachment factors to concentrate virions at the cell surface, however little is known regarding the specific receptors utilised by these viruses to enter host cells. Patrick’s group uses a range of molecular, biochemical and virological approaches to identify specific cell surface virus receptors to characterise how they recognise and internalise viruses.

    • Identifying novel antiviral genes and understanding how they block influenza virus infection

      Alveolar macrophages are susceptible to seasonal IAV infection but block virus growth whereas monocyte-derived macrophages and airway epithelial cells support virus growth. Therefore, alveolar macrophages express (unknown) host factors that block seasonal IAV. Of interest, highly pathogenic avian influenza (HPAI) H5N1 does grow in alveolar macrophages and therefore evades restriction factors that block seasonal IAV. In Patrick’s laboratory, they are developing experimental approaches to examine individual host genes to assess their ability to block the growth of seasonal IAV. Moreover, they are investigating the viral determinants of HPAI H5N1 that allow them to evade these host restriction factors.

    • Brown Group

      Lorena’s group is dedicated to understanding different aspects of influenza virus structure and replication, as well as the host immune response to the virus that may impact on disease outcome. They study areas of vulnerability that can be targeted by vaccines and therapeutics to control seasonal and highly pathogenic isolates.


    • Deng Group

      While her team’s core task has always been on the molecular surveillance of influenza viruses and its methodology development, Yi-Mo’s group have been collaborating actively both within and outside the Centre on several research projects relating to the molecular characterisation and evolution of human or animal influenza viruses. 


    • Hurt Group

      Aeron’s research team at the WHO Collaborating Centre for Reference and Research on Influenza works on aspects of understanding the replication and transmission of drug resistant influenza viruses, characterising novel drug resistance mutations, and the global movement and evolution of human and avian influenza viruses.


    • Kedzierska Group

      Professor Katherine Kedzierska’s team researches the immunity to viral infections, especially the newly emerged influenza viruses. Her work spans basic research – from mouse experiments to human immunity, through to clinical settings, with a particular focus on understanding universal CD8+ T cell immunity to influenza viruses. Her studies aim to identify key correlates of severe and fatal influenza disease in high-risk groups including children, the elderly and Indigenous Australians.

    • Kent Group

      Stephen’s group studies immunity to HIV, influenza and SARS-CoV-2. They are analysing a variety of vaccine strategies, including nanoparticle-based vaccines. They are studying a series of immune responses to gain better insights into protective immunity to important viral pathogens. They are developing monoclonal antibody therapies for HIV, influenza and SARS-CoV-2 to improve the treatment of these infections. The Kent group works very closely with Dr Amy Chung’s laboratory at the Doherty Institute.

      Other work areas include:COVID-19, Immunology, HIV


    • Sullivan Group

      Sheena’s epidemiology group at the WHO Collaborating Centre for Reference and Research on Influenza undertakes research into understanding influenza vaccine effectiveness and the validity of the methods used to estimate it. The group also provides technical assistance to partners in the Western Pacific Region of the WHO. 

      Other work areas include:COVID-19, Immunology, Viral Infectious Diseases


    • Valkenburg Lab

      The Valkenburg laboratory investigates viral immunity to emerging viruses with pandemic potential: influenza viruses and SARS-CoV-2. Our work spans randomised control vaccine trials, observational studies of infected patients and animal models to decipher immune correlates to drive novel translational outcomes for specific diagnostics, targeted therapeutics and next generation vaccines for public health impact.

    • Wakim Group

      Linda’s group’s main research focus is understating the mechanism of action and regulation of expression of antiviral proteins. Linda’s group also aims to characterise CD8 T cell responses within the lung following virus infection. 

      Other work areas include:Immunology


    Clinical Research

    Anyone can be infected by influenza, but some people are more susceptible to infection, severe disease and clinical complications. Clinical studies at the Doherty Institute are focused on specific risk groups, seeking to understand characteristics of viruses and the immune system that result in increased susceptibility and clinical severity. In particular, current studies are considering:

    Doherty Institute researchers are also characterising immune responses to influenza vaccination or infection in various groups of people, including:
