SARS-CoV-2 mutated spike proteins show variations in cell entry

A new study by Japanese scientists published on the preprint server bioRxiv* in June 2020 shows that the D614g mutation in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein can enhance the infectivity of the virus while leaving it vulnerable to neutralization by antibodies.

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.

Scientists isolate powerful SARS-CoV-2 -neutralizing antibodies from COVID-19 patients

A new study has shown that potent antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could help protect against COVID-19 infection. Preliminary results in animal studies have so far proven successful. The study titled, "Isolation of potent SARS-CoV-2 neutralizing antibodies and protection from disease in a small animal model," was published in the latest issue of the journal Science.

Antibiotic X-206 effective against SARS-CoV-2 in vitro

The current study published on the preprint server bioRxiv aims to understand how these compounds affect SARS-CoV-2 in vitro. The researchers from Aarhus University in Denmark examined 11 natural PEIs, with a single synthetic analog, screening them for inhibitory activity against the CPE of SARS-CoV-2 infecting cultured cells with overexpression of TMPRSS2, a serine protease that is instrumental in cleaving the spike protein of the virus.

Researchers develop a simple tool for making mouse models of COVID-19

Until there are effective treatments or vaccines, the COVID-19 pandemic will remain a significant threat to public health and economies around the world. A major hurdle to developing and testing new anti-viral therapies and vaccines for COVID-19 is the lack of good, widely available animal models of the disease.

Key factors to "flattening the curve": Western Washington state's COVID-19 experience

Despite having the first confirmed case of coronavirus and the first major COVID-19 outbreak in the United States, the state of Washington implemented a response plan that kept its death rate the lowest among all states that have had major outbreaks.

New discovery could open door to next generation malaria vaccine

In an unprecedented first, scientists at Seattle Children's Research Institute have developed a genetically attenuated parasite (GAP) that arrests late in the liver stage of human malaria.

Study reports structure of enzyme activator for high pathogenic avian influenza

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the current pandemic of COVID-19, is the focus of many investigators seeking to find an effective vaccine or therapeutic. Among the potential targets are various protease enzymes suspected of allowing the virus to gain entry to host cells and establish a successful infection.

New model predicts patients’ likelihood of testing positive for COVID-19

Cleveland Clinic researchers have developed the world's first risk prediction model for healthcare providers to forecast an individual patient's likelihood of testing positive for COVID-19 as well as their outcomes from the disease.

Multilevel interventions improve overall rate of HPV vaccinations

New research from Boston Medical Center shows that providing education and training to pediatric and family medicine providers about the importance of human papillomavirus vaccines, in tandem with healthcare systems changes including starting an HPV vaccination series before the age of 11, improves the overall rate of HPV vaccinations among adolescent patients.

Human antibodies provide powerful protection against SARS-CoV-2 in animal tests

A team led by Scripps Research has discovered antibodies in the blood of recovered COVID-19 patients that provide powerful protection against SARS-CoV-2, the coronavirus that causes the disease, when tested in animals and human cell cultures.

Tracing coronavirus habitats with genomics

Now, a new study by researchers at the University of Ottawa and published on the preprint server bioRxiv in June 2020 reports the differences in genomes of viruses that are exposed to antiviral proteins vs. those that are not. This host-derived pressure on the virus to adapt may help devise newer ways to build an effective vaccine.

UIC clinical trial to soon test a vaccine for COVID-19

The University of Illinois at Chicago will soon test a vaccine for COVID-19.

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.

Tumor-resident T cell levels underlie improved survival in throat cancer patients

Research led by the Centenary Institute has discovered that immune cells accumulating within the tumor environment, called tumour-resident T cells, are a critical determinant in survival rates of patients suffering from throat cancer.

Study shows 1 in 15 parents is hesitant about routine childhood vaccines

A national study measuring parental attitudes toward vaccinations found 6.1% were hesitant about routine childhood immunizations while nearly 26% were hesitant about the influenza vaccine.

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.

Glycans "lock and load" the SARS-CoV-2 spike protein for infection

A new study by scientists from the University of California San Diego, USA and Maynooth University, Ireland and published on the preprint server bioRxiv* in June 2020 reports preliminary results showing that the spike protein of the SARS-CoV-2, as well as its glycan coat, has “hitherto unseen functional and structural” properties. These may be useful in designing novel therapeutics to target this molecule.
