Interesting study on which species may be infected by SARS-CoV-2

The team from the University of Cambridge and the Pirbright Institute found that the Spike protein on SARS-CoV-2 engages with the host cell receptor angiotensin-converting enzyme 2 (ACE2) across a wide range of animals, even though the Spike binding site shows a between-species variation in its amino acid composition.

Infants tested positive for COVID-19 mostly have mild illness with fever

A report from Ann & Robert H. Lurie Children's Hospital of Chicago shows that infants under 90 days of age who tested positive for COVID-19 tend to be well, with little or no respiratory involvement. Fever was often found to be the primary or only symptom.

Direct structural link between SARS-CoV-2 and essential fatty acid

Now, a new study published on the preprint server bioRxiv in June 2020 reports the discovery of a novel free fatty acid (FFA) binding pocket on the SARS-CoV-2 virus that could explain in part the viral effects of hyperinflammation, immune modulation, and membrane structure.

Balanced B and T cell response required to control SARS-CoV-2

A new study by researchers in the Netherlands and published on the preprint server bioRxiv in June 2020 describes the differences in T and B cell responses seen in patients with severe COVID-19.

COVID-19 plasma therapy safe and improves survival, says large study

Researchers working on COVID-19 therapy with plasma from convalescent patients have found that it is safe and effective and improves the chances of survival among those who are severely ill. The new study titled, “Safety Update: COVID-19 Convalescent Plasma in 20,000 Hospitalized Patients,” is published as a preprint for the journal Mayo Clinic Proceedings.

Italy’s sewage water shows SARS-CoV-2 present prior to reported outbreak in Wuhan

Italian researchers have found traces of the novel coronavirus SARS-CoV-2 in sewage wastewater that indicates that the virus may have been in circulation since December 2019. This controversial discovery shows that even before the first case was reported in Wuhan, China, in late December 2019, the virus had already arrived in northern Italy.

How an ignored white blood cell may cause COVID-19 deaths

News-Medical speaks to Professor Lola Eniola-Adefeso about her research investigating how an ignored white blood cell may cause COVID-19 deaths.

Characterizing "re-positives" in recovered COVID-19 patients

The novel coronavirus pandemic has been spreading silently or explosively in almost every country of the world, causing almost half a million deaths and nearly 8.5 million reported cases in just six months. While much is known about the virus and the illness by now, far more remains unclear. One such is the prevalence and persistence of antiviral immunity following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Discovery of biomarkers that can influence COVID-19 severity

The novel coronavirus, now called the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), is the causative agent of the dreaded coronavirus disease (COVID-19). It was first discovered in Wuhan City, China, back in late December 2019 and has since then spread throughout the globe.

Human trials to commence using SARS-CoV-2 antibodies from cow's blood

The coronavirus pandemic has sparked a sense of urgency as it actively spreads across the globe. The number of reported cases has now surpassed 8.46 million people, with a death toll of more than 453,000. Scientists and pharmaceutical companies are racing to develop an effective treatment and vaccine against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Nanosponges attract coronavirus away from lung cells, study shows

Imagine if scientists could stop the coronavirus infection in its tracks simply by diverting its attention away from living lung cells? A new therapeutic countermeasure, announced in a Nano Letters study by researchers from Boston University's National Emerging Infectious Diseases Laboratories and the University of California San Diego, appears to do just that in experiments that were carried out at the NEIDL in Boston.

Blood types and COVID-19 risk confirmed

Blood type may play a pivotal role in driving disease severity among coronavirus disease (COVID-19) patients. Genetic analysis of COVID-19 patients has shown that people with blood type O seemed to be protected against severe disease. In contrast, those with blood type A may experience complications tied to the viral infection.

Crystal structure of SARS-CoV-2 protease-inhibitor in complex with a Chinese herb Shikonin

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has been spreading rampantly over the whole world, infecting millions of people (over 8.45 million at last count), with over 452,000 deaths, as of June 19, 2020. It causes a broad spectrum of disease manifestations, from asymptomatic disease to severe or even fatal respiratory symptoms.

Novel SARS-CoV-2 antibody cocktail impeccably mimics human antibody response

By using both humanized mice and convalescent patients, the researchers from the US and Singapore successfully generated non-competing and highly potent monoclonal antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein that could potentially be combined to form antibody cocktails. Their groundbreaking paper is published in the leading research journal Science.

First genome-wide CRISPR screen reveals genes that control SARS-CoV-2 infection

By performing a genome-wide CRISPR screen on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), U.S. researchers identified novel proviral genes and pathways, and highlighted host genes that may regulate coronavirus disease (COVID-19) pathogenesis, as well as revealing potential targets for novel treatment approaches. Their findings are currently available on the bioRxiv* preprint server.
