If you, or someone you love, seek treatment for influenza or viral pneumonia more than 48 hours after the onset of symptoms, no specific cure is currently available. Sadly, this reality will mean death for many previously healthy people, as it did for many Australians during the 2017 flu season. But there may be hope.

Extending the reach of antivirals and treatment for viral pneumonia

Dr Guna Karupiah, Associate Professor of Biomedicine in the UTAS School of Medicine, is an expert in immunology and virology. He has devoted his career to researching the immune response to pox and influenza virus infections. In a major breakthrough, Dr Karupiah’s latest research has revealed that antivirals will effectively treat influenza pneumonia long after 48 hours post-onset of symptoms if they are used in combination with anti-inflammatory drugs – at least it has, to date, with mice.

‘One logical conclusion behind these findings is that our immune response is actually preventing these antivirals from working,’ Dr Karupiah said. ‘Inflammation is an important part of the body’s response against any viral infection, and pneumonia is excessive inflammation of the lung, produced when the immune system goes out of control. If it’s a new strain of virus, which our body has not been exposed to previously, the immune system overreacts to control the infection and inadvertently causes a lot of damage through inflammation. That is where the anti-inflammatories can be effective.

‘We will need to do more animal experiments to ensure that our findings are robust and reproducible. The next step would be to get funding for clinical trials in humans. That’s a while away, but it’s a big finding because we’ve been able to demonstrate it in two different viral models. If we reduce inflammation long after the onset of symptoms, we can actually make the antivirals work.’

Drawing on previous research

Dr Karupiah has extensive experience in working with mousepox, an excellent small animal surrogate model for smallpox. The mousepox model has been crucial to understanding why the smallpox virus killed up to 40 per cent of infected individuals. The mousepox virus is a mouse pathogen and has co-evolved with mice, just as the smallpox virus has co-evolved with humans. Both viruses have close similarities in terms of respiratory infection, disease and pathogenesis and are also in the same virus family.

Based on the success of the mousepox model, which provided an insight into the pathogenesis of viral infections, Dr Karupiah applied some of the findings to his research into influenza pneumonia. As had been shown by others previously, the antiviral drugs didn’t work in mice in the influenza model post-onset of symptoms, just like they don’t in humans. But when anti-inflammatory drugs were used in combination with the antivirals, the mice could be treated and fully recovered. The anti-inflammatory drugs that were used are already available for use in humans.

‘I decided to work on the antivirals because there is a huge gap in what is needed,’ Dr Karupiah said. ‘There is a lot of research in laboratories around the world in making vaccines more effective, but there’s not much going on in terms of how we can treat an individual who is already infected and presents to a doctor long after the onset of symptoms.

‘So there is a lack of treatment for people who are infected with influenza and develop pneumonia, but this problem is not unique to influenza. We’ve done this research with the mousepox model as well. We also know that, for example, the chickenpox virus can be reactivated as shingles in some adults, but the antivirals don’t work if those individuals present to a doctor 48 to 72 hours post-onset of symptoms. So my thinking is that what we’ve been able to show with the pox virus and the influenza virus models is probably going to be applicable to other viral infections as well.’

Since joining UTAS in 2016, Dr Karupiah has also been teaching in the School of Medicine. Previously he worked as a postdoctoral fellow at the National Institutes of Health (NIH, USA) at the Laboratory of Viral Diseases and then the Laboratory of Immunopathology, before returning to Australia to lead successful labs at the University of Sydney and the Australian National University.

Associate Professor Guna Karupiah (Guna) is internationally regarded as an expert on immunity to pox and other generalized viral infections. The significance and impact of his research is evidenced by the highly competitive fellowships he has held, invitations to national and international conferences and workshops, invitations to expert or advisory panels, professional activities and peer review involvement.

His current interests and research projects are immunological memory (humoral immunity), viral infection induced immunopathology (viral pneumonia, cytokine storm) and viral immune evasion.


Guna trained as a microbiologist (BSc Hons) and then specialised in medical virology and epidemiology (MSc) at the University of Malaya. After completing his PhD in viral immunology at the John Curtin School of Medical Research (JCSMR), Australian National University (ANU), he worked as a postdoctoral fellow at the National Institutes of Health (NIH, USA) at the Laboratory of Viral Diseases and then the Laboratory of Immunopathology. After returning to Australia, has headed successful labs at the University of Sydney and the ANU. He joined the School of Medicine, University of Tasmania in January 2016.

Research Themes

Guna’s research aligns with the University’s research theme of Better Health.The long-standing focus of his research has been to understand the mechanics of an optimal immune response to viral infection with the ultimate goal of developing new efficacious vaccines and ways of intervening in the disease process if infection takes hold. As the host immune response has co-evolved with pathogens, meaningful investigations require appropriate virus-host models and this principle has guided his work. He strongly believes that understanding immune mechanisms at the molecular level through basic research using animal models is a key for translation into innovative and usable outcomes for treating infectious diseases in humans.

Current projects

1. Why do live viral vaccines induce life-long, protective antibody responses?

Vaccination with live viral vaccines provides life-long immunity. In contrast, inactivated vaccines induce short-lived antibody responses. In this project, the molecular and cellular basis for these differences will be investigated, utilizing novel recombinant viruses as well as transgenic, mutant and wild type mice to address some fundamental questions in immunology. It will involve techniques in immunology, virology, molecular biology and proteomics. This project is relevant for developing improved vaccination strategies.

2. A novel approach to treatment of viral pneumonia

Viral infection-induced pneumonia is a consequence of an over-exuberant immune response associated with dysregulated inflammatory cytokine production. There are no specific treatments available for viral pneumonia. We have developed a novel regime for treatment of viral pneumonia and preliminary results indicate that a combination of an antiviral plus a second compound is very effective in significantly reducing viral load, lung pathology and increasing survival even if treatment is started after onset of symptoms. This project will investigate the mechanisms through which the combination therapy ameliorates pneumonia and will assess the effectiveness of additional compounds. The project will utilize various strains of influenza A virus, wild type, gene knockout and gene knockin mice and will involving immunology, virology, molecular biology, cell signaling and histopathology techniques.

3. Mechanisms of protection of the host by virus-encoded TNF receptor homolog

Tumor necrosis factor (TNF) is a type II transmembrane cytokine (mTNF) expressed on activated cells and cleaved by a metalloproteinase to yield the soluble form (sTNF). Poxviruses encode TNF receptor (vTNFR) homologs of the extracellular domain of mammalian TNFR, which can potentially subvert the host immune response. Ectromelia virus (ECTV), an orthopoxvirus closely related to variola virus (smallpox virus) and a natural mouse pathogen, encodes a vTNFR that is secreted. This project will investigate how vTNFR modulates the host response using genetically engineered mutant viruses and gene knockout/knockin mice. It will use immunology, virology, molecular biology and cell signaling techniques. This project is highly relevant to anti-TNF therapies currently used to treat chronic inflammatory diseases.

4. Mouse and viral schlafen genes in infection and immunity

Some members of the family of human and mouse schlafen (Slfn) genes are involved in the activation and differentiation of immune cells. The mechanisms through which the Slfn proteins mediate their activities or the proteins they interact with are not known. Variola virus (VARV, the causative agent of smallpox in humans) and ectromelia virus (ECTV), a mouse-specific virus causing a smallpox-like disease (mousepox) are both poxviruses, which encode homologs of the mammalian schlafen genes. This project will investigate the mechanisms through which viral schlafen gene expression modulates the host immune response. It will utilize novel, genetically engineered mutant viruses and gene knockout/knockin mice involving immunology, virology, molecular biology and cell signaling techniques.

Novel combination therapy for effective virus control and amelioration of influenza pneumonia (2019)$23,875
There is currently no treatment available for viral pneumonia. We have developed a novel combination therapy for effective control and amelioration of influenza pneumonia. The drugs we use are currently used in humans, however not for the purpose described in the application. We do not yet know the mechanisms through which the combination treatment affords protection, and if the drugs can be administered through the respiratory route to treat influenza pneumonia effectively.We do not yet know the mechanisms through which the combination treatment affords protection, and whether the drugs can be administered through the respiratory route to treat influenza pneumonia effectively. These questions form the basis of the application. An understanding of both the mechanism(s) through which the treatment works, as well as determining an effective and practical route of delivery, will result in targeted, efficacious, and feasible clinical solutions to treatment of influenza pneumonia.
