An improved tetravalent antibody blocks SARS-CoV-2 infection

A new study published on the preprint server bioRxiv* in June 2020 shows the potential of a new fusion molecule called a biparatopic protein to inhibit viral interaction with the host cell ACE2 receptor. This could lead to therapeutic applications.

Norway pulls coronavirus contact tracing App due to privacy concerns

Amid the coronavirus pandemic, many countries have launched contact tracing apps to help contain the spread of the virus. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across most of the world, now infecting more than 8.17 million people; hence, extensive contact tracing is a vital tool to prevent its vast spread.

Research team generates comprehensive developmental map of human T-cells

Chintan Parekh, MD, of The Saban Research Institute of Children's Hospital Los Angeles, has led a team of investigators that generated a comprehensive roadmap for how T-cells develop in the human thymus.

Combination of antibodies and internal radiation can help fight cervical cancer

The sugar coating on cancer cells helps them thrive, and a new study indicates patients with cervical cancer who make antibodies to those sugars appear to do better when they also receive internal radiation therapy.

Scientists develop molecules that can remodel gut bacteria to a healthier state

Scientists at Scripps Research have developed molecules that can remodel the bacterial population of intestines to a healthier state and they have shown--through experiments in mice--that this reduces cholesterol levels and strongly inhibits the thickened-artery condition known as atherosclerosis.

Testing reveals 11 percent of people in Geneva infected with SARS-CoV-2

Now, a team of researchers at Geneva University Hospitals has found that less than 11 percent of the population in Geneva has contracted the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their research is published in the journal The Lancet.

Inhaled steroids reduce ACE2 expression in COPD lungs

A new study by scientists at Imperial College London, University of Newcastle and Prokarium, and published on the preprint server bioRxiv* in June 2020 examines the role played by inhaled corticosteroids (ICS) in the risk of acquisition of COVID-19 infection by COPD patients.

An inverse relationship between smoking and COVID-19

Researchers at the University of Washington and Stanford University School of Medicine have reported a significant inverse relationship between current smoking and coronavirus disease 2019 (COVID-19) mortality rates across forty countries.

BCG vaccination strengthens the immune system

A tuberculosis vaccine developed 100 years ago also makes vaccinated persons less susceptible to other infections. While this effect has been recognized for a long time, it is not known what causes it.

Combination of nelfinar and amodiaquine shows promise for treating COVID-19

Six months into the COVID-19 pandemic, more than 7.4 million people have been infected, and more than 410 000 have died. As yet, there is no treatment or vaccine for the disease.

GlobalData: New Zealand’s aggressive approach to control COVID-19 spread has proven to be effective

After a little over 100 days since the first confirmed case of COVID-19 reported on 28 February 2020, New Zealand has lifted almost all restrictions after reporting no active cases in the country.

Tuberculosis and polio vaccines may offer temporary protection against SARS-CoV-2

As the world grapples with the coronavirus disease (COVID-19) pandemic, scientists race to develop an effective vaccine to protect against the deadly SARS-CoV-2 virus. While potential vaccines are still being developed and tested, researchers propose that existing vaccines could give the immune system a temporary boost to ward off infection.

Remdesivir prevents replication of SARS-CoV-2 in human intestinal organoids

A new German study published on the preprint server bioRxiv* in June 2020 shows that the drug remdesivir can reduce the replication of SARS-CoV-2 in human intestinal organoids.

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.

Early neutralizing response to SARS-CoV-2 dominated by IgA antibodies

Researchers from France and the U.S. demonstrated how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection could induce an early and vigorous virus-specific IgA response that paves the way for the production of SARS-CoV-2 IgG antibodies, with even better neutralizing properties. Their paper is currently available on the medRxiv preprint server.

NIAID and Moderna scientists describe SARS-CoV-2 vaccine development

Researchers at the National Institute of Allergy and Infectious Diseases and Moderna Inc., have described the potent neutralizing effects of a candidate vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is currently being tested in a phase II trial.

New experiment could help attenuate inflammatory reactions during severe Covid-19 cases

The fourth parabolic flight organized by the UZH Space Hub takes off today from Dübendorf airfield. A reorganization taking into account Corona safety measures has made this possible.

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.

UNC scientists develop new kind of antibody test for COVID-19

As the COVID-19 pandemic continues with many thousands of new infections reported each day, there is a need for widely applicable surveillance testing to gain a better understanding of infection rates, especially the number of infections in people with mild or no symptoms, who can still be carriers.
