Multivalent nanobodies show improved neutralization activity against SARS-CoV-2

A state-of-the-art engineering approach toward improving the neutralizing activity of a cross-reactive nanobody, previously generated against the original SARS virus, showed it can be an attractive and viable option against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study is published in the journal Advanced Therapeutics.

COVID vaccines generate antibodies in saliva

Researchers in the United States and Canada have conducted a study showing that the vaccines developed by Pfizer-BioNTech and Moderna to protect against coronavirus disease 2019 (COVID-19) generate local antibody responses in the salivary gland that are independent of the systemic immune response.

Vaccination may protect against SARS-CoV-2 infection at the eye surface

Researchers in Australia have conducted a study showing that vaccination against coronavirus disease 2019 (COVID-19) induces key antibodies at the eye surface that may help to protect against the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Two monoclonal antibodies broadly neutralize SARS-CoV-2 variants of concern

Researchers in the United States and Canada have described the structural basis and mode of action for two monoclonal antibodies that potently neutralize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Monoclonal antibody could inform development of pan-coronavirus vaccines

Researchers in the United States have demonstrated the potential of a monoclonal antibody to inform the design of pan-coronavirus vaccines that could prevent the outbreak of future pandemics such as coronavirus disease 2019 (COVID-19).

The role of natural killer cells in the fight against coronavirus infection

This study proposes a mathematical framework to analyze the effect of the viruses on type I interferon (IFN-I) signaling, which is part of the innate immune response. IFN-I brings about natural killer cell activation, which in turn causes the activation of macrophages.

Study finds only 15% of rural health care workers have SARS-CoV-2 antibodies

Antibody testing of health care workers in three rural counties in eastern South Dakota and western Minnesota showed only 15% of the study participants had antibodies to the novel coronavirus.

Study shows COVID-19 organ-specific outcomes depend on anti-spike glycoprotein antibodies

A recent study from the University of Rochester reveals how the biodistribution kinetics and the affinity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for many different organs in the human body can be affected by antibodies targeting viral spike glycoprotein. The paper is currently available on the bioRxiv* preprint server while it undergoes peer review.

“Sybodies” protect against SARS-CoV-2 in hamster model

Researchers in China, The Netherlands, France, and Switzerland have identified synthetic nanobodies or “sybodies” that exhibit potent neutralizing activity against severe acute respiratory syndrome coronavirus (SARS-CoV-2) – the agent responsible for the ongoing coronavirus disease 2019 (COVID-19) pandemic.
