Novel SARS-CoV-2 variants partially resistant to infection- and vaccine-induced immunity, study finds

A recent study conducted by a team of scientists in the Netherlands has revealed that while severely affected hospitalized COVID-19 patients and vaccinated individuals are capable of neutralizing the B.1.1.7, B.1.351, and P.1 variants of SARS-CoV-2, a significant proportion of non-hospitalized patients with less severe COVID-19 remain susceptible to these viral variants.

Could higher carnitine levels in the blood protect against severe COVID-19?

Researchers at the MRC Integrative Epidemiology Unit (IEU), Bristol Medical School, University of Bristol, Bristol, UK, found that carnitine and its derivative acetyl-carnitine provide a protective effect against severe COVID-19. Doubling of carnitine or acetyl-carnitine is tied to a 40-percent reduction risk of disease progression.

Could certain genes be associated with a loss of smell in some COVID-19 patients?

Researchers at the 23andMe COVID-19 Team, who help search for genetic links associated with the severity of COVID-19, found that the genes UGT2A1 and UGT2A2 may be associated with the loss of smell in those infected with SARS-CoV-2.

Could semen quality indicate SARS-CoV-2 insult susceptibility in polluted areas?

In a recent review in Environmental Science and Pollution Research, Italian researchers focused on “the evidence that correlates the degree and type of pollution with the increased susceptibility of many countries to this pandemic and proposes human semen as an early marker of the environmental health and the general health of individuals.” Their observations are based on a robust body of experimental evidence.

New vaccine candidate with RBD and N protein targets protects against SARS-CoV-2 in preclinical trials

A recent study published in the journal Science Advances, explores the immunization of RBD with the P2 epitope of tetanus toxoid, to enhance its immunogenicity, and also tests the benefit of N protein in the vaccine.

Coronavirus strain associated with dogs found in humans

Coronavirus strain associated with dogs found in swabs taken from pneumonia patients in Malaysia.

Can immunity form and interaction with seasonal coronaviruses influence SARS-CoV-2 epidemiology?

A new study hypothesizes that cross-protection from seasonal epidemics of HCoVs could not only affect SARS-CoV-2 transmission but also protect children from the disease.

Could 3D printed swabs be used to collect COVID-19 test samples?

Researchers have evaluated 3D printed sample collection swabs made in-house and found them to be a reliable alternative to commercial swabs.

SARS-CoV-2 can be neutralized by UV-A and UV-B

Since the end of the 1800s, Ultra-violet (UV) light has been widely documented for its germicidal properties. The UV-C light produced by low-pressure mercury tubes is widely used for disinfecting wastewater, closed environments, and biological products and is well-established, safe, and economical. UV light can have a germicidal effect on bacteria and viruses.

Novel antibody engineering approach

Scientists from the Johns Hopkins University School of Medicine, USA, have recently developed an Antibody Display technology by grafting the second extracellular domain of tetraspanin12 (Tspan12EC2) and the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein on the heavy chain complementarity-determining region 3 (CDR3).

Global land-use changes are creating "hot spots" for potential emergence of new coronaviruses

Global land-use changes -- including forest fragmentation, agricultural expansion and concentrated livestock production -- are creating "hot spots" favorable for bats that carry coronaviruses and where conditions are ripe for the diseases to jump from bats to humans, finds an analysis published this week by researchers at the University of California, Berkeley, the Politecnico di Milano (Polytechnic University of Milan) and Massey University of New Zealand.

Researchers identify kite-shaped molecules that block SARS-CoV-2 cell entry after attachment

They have identified a group of kite-shaped compounds that are highly specific to SARS-CoV-1 and SARS-CoV-2. These compounds demonstrate high potency in inhibiting SARS-CoV-2 infection at early entry steps. The study is currently available on the bioRxiv* preprint server.

Researchers find natural metabolites help SARS-CoV-2 escape antibodies

An international team of scientists has identified a human molecule — biliverdin — as a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) target. The binding of the heme metabolite to the N-terminal domain of SARS-CoV-2 is associated with the virus’s ability to dodge the immune system by suppressing antibody binding to the spike protein.

CDC study finds contact tracing helps prevent further cases of COVID-19

The study “Estimates of cases and hospitalizations averted by COVID-19 case investigation and contact tracing in 14 health jurisdictions in the United States” is available as a preprint on the medRxiv* server, while the article undergoes peer review.

Study confirms poor immunogenicity in hemodialysis patients receiving single dose BNT162b2 vaccine

Researchers from Ontario, Canada, recently conducted a prospective observational study to determine the SARS-CoV-2 antibody response in chronic hemodialysis patients following one vs. two doses of the BNT162b2 COVID-19 vaccine. The results were compared to health care worker controls and convalescent serum.

Scientists explain possible causes of anaphylaxis following mRNA COVID-19 vaccination

New research from a team of scientists at the Centre for Research in Molecular Modeling, Department of Chemistry and Biochemistry, Concordia University in Canada, has aimed to determine the potential causes of anaphylaxis or allergic reactions reported in some individuals after receiving COVID-19 vaccines, including the mRNA vaccines by Pfizer-BioNTech and Moderna.

Compelling evidence of SARS-CoV-2 exposure and neutralizing antibodies in domestic cats in Peru

Although Peru is one of the countries most affected by the pandemic, no studies had been conducted to investigate SARS-CoV-2 seroprevalence among domestic cats. Recently, researchers from Peru demonstrated the presence of neutralizing antibodies for the receptor binding-domain (RBD) of the SARS-CoV-2 spike protein in cats in Lima, Peru. The owners of the cats in the study had confirmed SARS-CoV-2 infection.

Antibody cocktail effectively inhibits SARS-CoV-2 in the rhesus macaque model

Researchers from the US tested the prophylactic potential of a combination of 2 mAbs administered 3 or 75 days before respiratory challenge in rhesus macaques. They used the rhesus macaque model to test the added benefit of combinatory parenteral administration of 2 high-affinity anti-SARS-CoV-2 mAbs - C144-LS and C135-LS. These mAbs were developed to neutralize the virus and tweaked to improve their pharmacokinetics.

ALG-097111 potently inhibits SARS-CoV-2 replication in Syrian Hamster model in vivo

A team of researchers from the US and Belgium applied a structure-based approach with early monitoring of cathepsin L inhibition along with SARS-CoV-2 3CLpro inhibition. They identified a potent and selective SARS-CoV-2 3CLpro inhibitor, ALG-097111, which has proven activity against SARS-CoV-2 in SARS-CoV-2 hamster models in vivo. This study is published in the journal, Biochemical and Biophysical Research Communications.

Study offers longitudinal roadmap of immune activation and resolution in mild COVID-19

Researchers from the US recently profiled the longitudinal immune response in mild COVID-19 patients starting with early time points of 1-15 days post-infection through convalescence to over 100 days after onset of symptoms.
