An entire trimeric S-protein of SARS-CoV-2 is necessary for protective immune response

Researchers from Seattle Children's Research Institute and the University of Washington described a high-throughput and rapid technique to quantify circulating levels of functional antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), suggesting that the entire viral spike protein should be used to characterize the immune response. Their paper is currently available on the medRxiv* preprint server.

Study: Only a minority of Geneva population has been infected by Covid-19 pandemic

A study carried out among 2'766 people by the University Hospitals of Geneva (HUG), the Geneva Centre for Emerging Viral Diseases, and the University of Geneva (UNIGE), Switzerland, reveals that, at the time of the decline of the Coronavirus pandemic, only 10.8% of the Geneva population had been infected with Covid-19.

Type III interferons can increase risk of bacterial "superinfections" in the lung, research shows

Interferons and other cytokines produced by the immune system are important defenses against viral infections, but as we have seen in COVID-19, they can also contribute to damaging, potentially life-threatening lung inflammation.

Females mount stronger T-cell response to SARS-CoV-2

A new study published on the preprint server medRxiv in June 2020 shows that immune cells, antibody levels, cytokine levels, and viral loads contribute to the sex difference seen in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Study looks at type I diabetes and COVID-19

Researchers from the United States have analyzed the information on type I diabetics and COVID-19. Their study titled, "Type 1 Diabetes and COVID-19: Preliminary Findings From a Multicenter Surveillance Study in the U.S.," is published in the latest issue of the journal Diabetes Care.

Anticardiolipin antibodies and COVID-19

A new study has shown that anticardiolipin antibodies are associated with the novel coronavirus infection or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19.

Deep UV LED inactivation of SARS-CoV-2 - fast and effective

The ongoing pandemic has aroused considerable effort to find methods to prevent and control the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19 disease. Rapid inactivation devices would be of great help in this area, to prevent viral transmission through aerosols and contact with infected surfaces.

COVID-19 produces lung inflammation in non-human primate experiments

A new study published on the online preprint server bioRxiv in June 2020 reports the successful use of three primate species to model the infection, pathogenesis, and clinical features associated with COVID-19. The research provides useful and immediately available models to test new vaccines and treatments.

Innovative effort solves health system's shortage of nasopharyngeal swabs

An innovative effort launched in April and led by a fellow in the UCLA Biodesign program has yielded positive results, solving the health system's shortage of nasopharyngeal swabs - a key element in COVID-19 testing - at a time when Southern California is seeing a rise in new cases and new deaths per day.

New strategy may facilitate development of multi-epitope peptide vaccine against SARS-CoV-2

By combining T and B lymphocyte analysis with manufacturability heuristic, researchers from the US and Germany proposed a set of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine peptides to use in subsequent animal studies and clinical trials. Their paper is currently available on the bioRxiv preprint server.

Deep vein clots in critical COVID-19 illness

A new research paper published in the journal JAMA Network Open in May 2020 reports a high incidence of deep vein clots in patients with severe COVID-19 at a single French medical center. This could indicate the need for systematic anticoagulant therapy in these patients as a preventive measure.

Study reports a low prevalence of COVID-19 in pregnant women

New data from two studies show the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among pregnant women is low, but they still need to take extra precautions.

Study finds very low level of SARS-CoV-2 in two San Francisco Bay areas

A new study published on the preprint server medRxiv in May 2020 reports a very low prevalence of antibodies in two separate populations living in the San Francisco Bay Area.

ACE2 receptors for SARS-CoV-2 in human eye

Since its emergence in Wuhan, China, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly over most of the world’s inhabited regions, causing millions of cases and hundreds of thousands of deaths. The primary symptoms of COVID-19, the disease caused by SARS-CoV-2, are fever, dry cough, and tiredness.

Children with COVID-19 presenting with sudden severe lung disease

Even as the COVID-19 pandemic continues to seek out new victims, puzzling new presentations are further confusing the situation. A new study published online in The Lancet Rheumatology in May 2020 reports a case of severe COVID-19 in a child who rapidly developed acute respiratory distress symptoms without prior respiratory symptoms. This case should alert clinicians to consider this diagnosis in children as well.
