Nutrition Scientist; Dr Kathryn O’Sullivan looks at the role of gut bacteria and the microbiome as a “major weapon in fighting COVID 19 for the Hippocratic Post. Focusing on the gut may support our return to normality in more ways than expected. Scientists think that the bacteria in our gut could be a major weapon in […]
How stress can stop immune cells in their tracks: Researchers have discovered that signals produced by nerves in response to stress can stop immune cells from effectively fighting pathogens or tumours. Led by University of Melbourne Professor Scott Mueller, Laboratory Head at the Peter Doherty Institute for Infection and Immunity (Doherty Institute), the study made the […]

Get to grips with gut health: Five tips for a fit and healthy year: As we head into the spring/summer season, our list of goals is always the same: plan fun activities, get in shape, reduce stress levels and live more healthily in general. Given that we were somewhat robbed of our spring & summer […]
Severe COVID-19 risk factors: The course and severity of COVID-19 in individual patients is largely influenced by the interaction between the SARS-CoV-2 coronavirus and the human immune system. Normally, the antiviral immune response of natural killer cells (NK cells) is an important step in combating viral replication in the early phase of the infection. On […]
Immune system protects children from severe COVID-19: Children are protected from severe COVID-19 because their innate immune system is quick to attack the virus, a new study has found. • A new Peer-reviewed Melbourne-led study has found children are protected from severe COVID-19 because their innate immune system is quick to attack the virus • […]

Aggressive cancers could be treated with immunotherapies that direct the immune system to kill cancer cells with specific drug resistance-causing mutations, a major new study suggests. Drug resistance mutations which restore activity of the BRCA1 or BRCA2 genes as a way of avoiding the effects of drug treatment could leave tumours vulnerable to the effects […]

Recommendations led by a team of UK-based cardiac researchers receive endorsement from the European Section for Sports Cardiology & Exercise Published paper provides practical answers to key questions posed by the international sporting community, ahead of a phased return to some professional sports, such as the Premier League football Evidence shows that regular, moderate exercise […]
At this time there is no proven effective treatment for Covid-19. Historically, a viral pandemic has led doctors and scientists to focus on finding an effective anti-viral drug or an effective vaccine. Neither of these have been particularly fruitful. It seems this focus is not in the right place especially given the propensity for viral […]

‘- Aggressive stomach and gullet cancers evolve escape routes under selective pressure from immune system – Findings underline importance of cancer evolution, and could help optimise immunotherapy Aggressive, highly mutated cancers evolve escape routes in response to immune attacks in an ‘evolutionary arms race’ between cancer and the immune system, a new study reports. Gullet […]

Professor Scott Byrne, based at the University of Sydney in Australia, is one of a team of researchers around the world looking into how sunlight may affect human health in many ways which are not yet fully understood. Here he answers some questions about how UV rays could affect the body’s immune system How do […]
