Characterization of lab-produced neutralizing antibodies targeting SARS-CoV-2

A new study led by Hans-Martin Jäck of the Friedrich-Alexander University Erlangen-Nuremberg in Germany engineered clusters of neutralizing monoclonal antibodies using a transgenic mouse model. A unique characteristic for the antibodies was the different ways it bound to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the overall reduction in the viral spread for […]

Plant-derived compound isorhamnetin may have antiviral potential against SARS-CoV-2

The lack of new or repurposed drugs to treat patients with severe or critical coronavirus disease 2019 (COVID-19) has been one of the biggest hurdles to reducing mortality rates in the ongoing pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A new study, published online in the journal Drug Development Research, describes […]

P681 mutation has little impact on transmissibility in the SARS-CoV-2 UK variant, finds study

The rollout of vaccines is on in an attempt to achieve population immunity against the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, the recent emergence of several variants that have altered transmissibility, infectivity and virulence characteristics has cast doubt on the feasibility of this goal. A […]

CAL20.C SARS-CoV-2 variant skyrocketing in California evades host immune response

The effect of different neutralizing antibodies, both vaccine-elicited and from convalescent sera, suggests new variants are emerging that can evade the human immune response. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to host cells via its spike protein, which has two parts, the S1 and S2 subunits. The S1 subunit has the receptor-binding […]

Can universal vaccines and treatments against future SARS-CoV-2 variants be developed?

Evolutionary ecology theory offers avenues to anticipate the future behavior of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen. The repeated emergence of more infectious and possibly more virulent variants of SARS-CoV-2 shows that the virus is adapting under selective pressure. Although there has been a lot of discussion on how biodiversity-related events facilitate […]

Research provides insights on why redheads exhibit altered sensitivity to pain

New research led by investigators at Massachusetts General Hospital (MGH) provides insights on why people with red hair exhibit altered sensitivity to certain kinds of pain. The findings are published in Science Advances. In people with red hair (as in numerous other species of animals with red fur), the pigment-producing cells of the skin–called melanocytes–contain […]

Both mRNA vaccines protect against emerging variants of SARS-CoV-2

Researchers in the United States and Canada have conducted a study showing that just a single dose of either the Pfizer-BioNTech or Moderna vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is likely to protect against emerging variants. The SARS-CoV-2 virus is the agent responsible for the coronavirus disease 2019 (COVID-19) pandemic that continues […]
