Our Research
Our laboratory studies cellular mechanisms utilised and modified by viruses during their replication. We currently study viruses from important families of human and veterinary pathogens: herpesviruses, polyomaviruses, and bunyaviruses.
Herpesviruses are large and complex enveloped dsDNA viruses that are ubiquitous pathogens of vertebrates and establish life-long latent infections in their hosts. Infections by the nine known human herpesviruses are associated with many serious diseases including certain lymphomas and life-threatening conditions in immuno-compromised patients. Herpesviruses encode a large number of multi-functional proteins that cause dramatic or subtle modifications of host cells enabling the evasion of antiviral responses and efficient production of new virions.
Polyomaviruses are small non-enveloped dsDNA viruses that are ubiquitous pathogens in humans and can establish life-long persistent infections with regular asymptomatic virus shedding. While polyomavirus infections are generally benign in immuno-competent hosts they are known to cause serious disease in immuno-compromised patients including haemorrhagic cystitis, polyomavirus-associated nephropathy, Merkel cell carcinoma, and progressive multifocal leukoencephalopathy.
Bunyaviruses are enveloped segmented negative-strand RNA viruses that are commonly transmitted by arthropods and includes many neglected tropical disease pathogens such as Rift Valley fever virus, Crimean-Congo haemorrhagic fever virus, and Oropouche virus. In collaboration with colleagues at São Paulo University we are investigating virus-cell interactions involved in the morphogenesis and egress of Oropouche virus, one of the most common arboviruses that infects humans in South America.
