Sylviane Muller MAE and others published a paper titled ‘Autophagy as an emerging target for COVID-19: lessons from an old friend, chloroquine’. Autophagy is the body’s mechanism to degrade and recycle old cellular components (organelles, proteins and cell membranes). The authors discuss how chloroquine (CQ) and hydroxychloroquine (HCQ) inhibit autophagy and could have potential therapeutic value in the treatment of COVID-19 patients.
Sylviane Muller MAE in collaboration with others published a paper titled ‘Neutrophilia and NETopathy as key pathologic drivers of progressive lung impairment in patients with COVID-19’. Severely ill patients experience acute respiratory distress with high levels of neutrophils and multiple cytokines causing an exaggerated inflammatory response. In this review, the authors discuss the need to develop therapies that inhibit neutrophil recruitment, activation, degranulation, and neutrophil extracellular trap (NET) release.
The COVID Human Genetic Effort is an international consortium of scientists around the world aiming to discover genetic differences between young patients with no underlying medical conditions that develop severe COVID-19 and patients that remain resistant even after repeated exposure to SARS-CoV2. Guiseppe Novelli MAE is part of the consortium and co-author of the paper ‘Inborn errors of type I IFN immunity in patients with life-threatening COVID-19’.

This review offers a useful summary of strategies for dealing with the COVID-19 pandemic in democratic countries. It includes information on the virus, how it affects humans, the routes of transmission and therapies for the disease. This pandemic playbook is a useful resource in the current pandemic and will be useful in the future when another pandemic might arise.
Giuseppe Novelli MAE is part of the COVID Human Genetic Effort and co-author of the paper ‘Life-threatening COVID-19: defective interferonsunleash excessive inflammation’. This paper discusses how severe COVID-19 pneumonia increases sharply after 65 years of age and how genetic defects as well as autoantibodies against type I interferons contribute to disease severity in at least 10% of critical cases.
Valerie O’Donnell MAE, in collaboration with others, published an evidence review titled ‘Potential role of oral rinses targeting the viral lipid envelope in SARS-CoV-2 infection’. This review examines published research on enveloped viruses including coronaviruses, showing that chemicals found in mouthwashes can damage the lipid membrane of enveloped viruses. The authors assessed existing mouthwash formulations for their potential ability to damage the SARS-CoV-2 lipid envelope in vitro. The evidence suggests the use of mouthwash could be an effective defence against COVID-19 and further research in this area is needed. This review was the first paper published by the journal FUNCTION.

Clinical neurological symptoms include dizziness, disturbed sleep, cognitive deficit, hallucinations and depression. COVID-19 damage to neural cells may increase the risk of neurodegenerative diseases like dementia.
