Thiol-based mucolytics show potent allosteric inhibition of SARS-CoV-2-ACE2 binding via disulfide reduction

A compelling report, recently released on the bioRxiv* preprint server, describes unexpectedly powerful inhibition of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by thiol-based mucolytic compounds P2119 and P2165, by preventing the virus spike from binding to its host cell receptor, the angiotensin-converting enzyme 2 (ACE2).

Dimeric IgA antibodies help identify recent SARS-CoV-2 infection

A fascinating new study, released as a preprint on the medRxiv* server, adds a highly appealing tool to the armory of detection techniques for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Its validation could allow the early and accurate detection of recent or active infection, which is valuable in tracing contacts and preventing forward transmission of the virus.

Scientists identify natural SARS-CoV-2 super immunity against 23 variants

The antibodies are capable of neutralizing a wide range of SARS-CoV-2 variants even at sub-nanomolar concentrations. In addition, the combinations of these antibodies reduce the risk of generating escape mutants in vitro. The study is published in the journal Science.

Novavax COVID-19 vaccine demonstrates ~90% efficacy against SARS-CoV-2

The findings reveal that the two-dose regimen of the vaccine is almost 90% effective against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Moreover, the vaccine shows high efficacy against the B.1.1.7 variant (Alpha) of SARS-CoV-2.

Rapid quantification of SARS-CoV-2 Spike-specific T cells by direct peptide stimulation of whole peripheral blood

To understand both the correlates of protection induced by vaccinations and the necessary immune responses to manage the COVID-19, researchers from Singapore used an alternative method to closely evaluate the kinetics and magnitude of specific T cell responses to SARS-CoV-2 infection. Their work was posted to the bioRxiv* preprint server while awaiting peer review.

Phylogenetic network analysis reveals recombinant origin of the SARS-CoV-2 alpha (B.1.1.7) variant

Researchers from the U.S. recently used the phylogenetic network approach to analyze the origin of the VOC202012/01 (alpha) or the PANGO Lineage B.1.1.7 variant, which was first reported in U.K. in 2020 and soon spread to other countries. This study is published on the bioRxiv preprint server while the paper undergoes peer review.

Researchers develop random priming amplification method for whole-genome sequencing of SARS-CoV-2 and H1N1

Researchers from the UK recently compared the performance of 4 different random priming amplification methods to recover SARS-CoV-2 RNA. In method 1 (H-P), the reverse transcriptase (RT) step included random hexamers, whereas, in methods 2-4, RT incorporated an octamer primer with a known tag. This study is published on the bioRxiv preprint server.
