Discovery of novel hidden gene in SARS-CoV-2

A team of researchers from Germany, Taiwan, and the United States has identified and characterized a new hidden gene in SARS-CoV-2 that is also present in Guangxi pangolin coronaviruses – though, curiously, absent in closely related pangolin and bat coronaviruses.

Spike-based DNA vaccine shows excellent protection against SARS-CoV-2 in a hamster model

A study conducted at the United States Army Research Institute of Infectious Diseases shows how a relatively simple full-length DNA vaccine against spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can elicit neutralizing antibody response in an animal model – even after a single shot with simple jet injection technique.

Host genetic "super-variants" may increase COVID-19 death risk

Researchers at Yale University have identified genetic variants among people of white British ancestry that may increase the risk of dying from coronavirus disease 2019 (COVID-19) – the illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Rheumatoid arthritis may increase risk of dying from COVID-19

Researchers in New Zealand and Australia have conducted a study showing that people with rheumatoid arthritis may be at an increased risk of death if they develop coronavirus disease 2019 (COVID-19) after becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Low prevalence of SARS-CoV-2 specific antibodies in Lubbock, Texas

A recent study published in the Journal of Primary Care and Community Health has assessed the prevalence of antibodies developed specifically against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in front-line workers in Lubbock, Texas. According to the study findings, immunoglobulin G (IgG)-specific anti-SARS-CoV-2 antibodies have been detected in only 0.73% of the participants.

Research tracks humoral immunity response over eight months post COVID-19 infection

Researchers from Chongqing Medical University have tried to answer one of the burning questions regarding the longevity of immune response to coronavirus disease 2019 (COVID-19): How long does immunity last after infection? Their study looked at the lasting effects and continued immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) over eight months after recovery from the infection.

Nafamostat mesylate initially reduces SARS-CoV-2 viral loads in hamsters, study finds

Researchers have found that nafamostat mesylate, when injected in the nasal cavity of Syrian hamsters, can decrease initial SARS-CoV-2 viral loads in their nose. However, this effect was temporary and further testing is required to determine clinically significant effects. The research group's findings are available on the preprint server bioRxiv*.

How SARS-CoV-2 blocks immune response

An international research team has confirmed the mechanism by which the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). Their article titled, “SARS-CoV-2 Orf6 hijacks Nup98 to block STAT nuclear import and antagonize interferon signaling,” is published in the journal Proceedings of the National Academy of Sciences.

Nearly 1 in 5 COVID-19 survivors develop mental illness within 90 days

A new study has found that people who have COVID-19 may have an increased risk of being diagnosed with a psychiatric disorder, including anxiety and depression, within 90 days after diagnosis.

COVID-19-associated pulmonary aspergillosis caused by aspergillus fumigatus

A new study published on the preprint server bioRxiv in November 2020 discusses the characteristics of COVID-19 associated pulmonary aspergillosis (CAPA).

SARS-CoV-2 spike glycoprotein optimized for conditions present in human airways

Researchers from Belgium and Germany demonstrated how the spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is fine-tuned towards the temperature and protease conditions of the human airways, which in turn enhances viral transmission and subsequent pathology. Their study is available on the bioRxiv* preprint server.

Endothelial cells resistant to SARS-CoV-2 infection

A team of scientists from Imperial College London has conducted a series of in vitro studies to investigate the susceptibility of endothelial cells to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the causative pathogen of coronavirus disease 2019 (COVID-19).

Critically ill COVID-19 patients experience novel platelet-activating immune complexes, study finds

Canadian researchers from McMaster University, Ontario, have pinpointed platelet activating immune complexes in coagulation disorders associated with coronavirus disease 2019 (COVID-19), the condition caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Severe COVID-19 linked to age, body mass index and ABO blood group

With the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infecting over 50 million people worldwide with hundreds of thousands experiencing severe respiratory illness, researchers have been trying to find the factors associated with severe disease. From the start of the pandemic in March this year, several studies have indicated heart disease, high blood pressure, diabetes, obesity, etc. could be linked to severe disease. Now German researchers have published a study on the association between severe respiratory infection caused by SARS CoV-2 and factors such as age, body mass index (BMI) and ABO blood group.

Identifying SARS-CoV-2 spike protein mutations resistant to antibodies

Using a set of different monoclonal antibodies, researchers determined different mutations in the SARS-CoV-2 spike protein that leads to resistance. Understanding these resistant mutations is important in developing effective therapeutic strategies.

Exosome-mediated mRNA delivery generates broad immune response to multiple SARS-CoV-2 proteins

Recently, researchers from The Johns Hopkins University School of Medicine, Baltimore, MD, USA, and Capricor Therapeutics, Inc., Beverly Hills, CA, USA, described a new approach to SARS-CoV-2 vaccine development using exosomes to deliver mRNAs that encode the antigens from multiple structural proteins of the virus.

After SARS-CoV-2 antibodies fade B and T-cells persist

Now, an international team of thirty researchers from Sweden, Italy, Germany, the USA, and China aimed to determine the longevity of the immune response against SARS-CoV-2, particularly the specific memory B-cell and T-cell responses over time in convalescent COVID-19 patients.
