McKeating Group
Established in 2017, the McKeating group in Oxford has been developing new methods to study the biology of hepatic liver disease. Recent advances include methods to identify the complex pattern of overlapping transcripts that are produced by viruses and new imaging approaches to visualise the genomes of HBV, HDV and other viruses within single cells. We are interested in the cellular basis of early infection events that define viral tropism and how this knowledge impacts pathogenesis and translates into new anti-viral strategies. We want to understand the simple, fundamental question of how, when and where do viruses replicate?
Viruses are intracellular pathogens and understanding host pathways that define susceptibility to infection and disease are essential for the design of new therapies. Viral replication is shaped by the cellular microenvironment and current projects focus on the spatial mapping of infected cells at single-cell resolution to identify the key factors that regulate virus tissue tropism.
Research Themes
Hepatitis viruses
Chronic hepatitis B and D viruses are a major cause of liver disease and cancer, with limited curative treatments. The liver is a naturally hypoxic organ and we have identified a role for hypoxia inducible factors to activate viral transcription. Our goal is to understand the hepatocyte-intrinsic and extrinsic pathways that define host susceptibility to these viruses. The frequency of infected cells in the liver is low and bulk RNA-sequencing approaches frequently overlook their complex transcriptomes. We have developed spatial transcriptional profiling methods to identify HBV and HDV infected hepatocytes and their uninfected neighbours. When combined with single molecule resolution imaging of viral RNAs, these exciting technologies allow us to study virus-host interplay at unprecedented detail.
Respiratory viruses
Globally respiratory infections are responsible for approximately 4.25 million deaths/year (pre-COVID), mostly in children and the elderly. Viruses are responsible for the majority of these infections and developing broadly active tools to fight these viruses is a priority. We have shown that hypoxia suppresses SARS-CoV-2 replication and inflammatory responses. We have recently extended these observations to Respiratory Syncytial virus and shown our HIF mimetic drugs potently inhibit infection by activating innate sensing and Interferon-signalling.
Research Funding
The McKeating lab are delighted to be amongst the recipients of a Wellcome Trust Discovery Award together with additional funding from the Medical Research Council and the Chinese Academy of Medical Science Oxford Institute. We aim to deliver an ambitious programme of research, applying cutting edge spatial technologies to study the mechanisms of persistence in both acute and chronic viral infection. We are excited to announce that we are welcoming applications for funded post-doctoral research positions.
