Research shows a unique T cell receptor repertoire in MIS-C patients

Children with coronavirus disease 2019 (COVID-19) sometimes develop the Multisystem Inflammatory Syndrome in Children (MIS-C), which is associated with high morbidity. The underlying T-cell associated mechanism is described by researchers in a new study published on the preprint server bioRxiv in November 2020, as a response to superantigen activation.

Behavioral responses to COVID-19 differ by age, study shows

A new study from the USC Leonard Davis School of Gerontology shows that the behavioral responses to COVID-19 differed by age.

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.

Smell and taste changes in general population may indicate COVID-19 spread

Self-reports of smell and taste changes provide earlier markers of the spread of infection of SARS-CoV-2 than current governmental indicators, according to an international team of researchers.

CDC says wearing facemask protects self and others from COVID-19

Throughout the pandemic, health experts have recommended the use of face masks to protect oneself from the virus. Now, the U.S. Centers for Disease Control and Prevention (CDC) stated that the wearing of masks protects not only the wearers but also everyone around them from contracting COVID-19.

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.

Uracil point mutations found in SARS-CoV-2 variants alter innate immune responses

Tohoku University scientists have found that human editing enzymes are likely behind a type of mutation in the COVID-19 virus that stimulates the release of pro-inflammatory molecules called cytokines by immune cells in the body.

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*.

Study identifies genetic risk for fatal blood clots in IBD patients

Blood clots are the biggest cause of death in patients with inflammatory bowel disease (IBD) ─ ulcerative colitis or Crohn's disease. In a retrospective study recently published in the journal Gastroenterology, Cedars-Sinai investigators found that a combination of rare and common genetic variants in some IBD patients significantly increased their risk of developing clot-causing thromboembolic diseases.

New study highlights the burden of post-COVID fatigue

More than half of people with acute COVID-19 infection continue to have persistent fatigue 10 weeks after their initial illness, according to a new study published November 9 in the open-access journal PLOS ONE by Liam Townsend of Trinity College Dublin, Ireland and colleagues.

Effectiveness of vitamin C against COVID-19 depends on its natural transporter levels

High doses of vitamin C under study for treating COVID-19 may benefit some populations, but investigators exploring its potential in aging say key factors in effectiveness include levels of the natural transporter needed to get the vitamin inside cells.

Researchers use machine learning algorithm to identify common respiratory pathogens

The ongoing global pandemic has created an urgent need for rapid tests that can diagnose the presence of the SARS-CoV-2 virus, the pathogen that causes COVID-19, and distinguish it from other respiratory viruses.

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.

Research examines changes in physical activity, sitting and sleep during Scotland's COVID lockdown

A new study by researchers at the University of Strathclyde, published as a preprint on the medRxiv* server, examined changes in 24-hour movement behaviors across three designated period blocks: from 1) pre-lockdown (T1) to the 1st UK national lockdown (T2); and 2) first UK national lockdown to initial easing of lockdown (T3).

Parents normalize children's symptoms to discount COVID-19, study finds

A new study by researchers from King's College London explores parental perceptions of COVID-19-like symptoms in their children and attitudes towards isolating them from others in the household when they are feeling unwell.

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.
