Interactions between SARS-CoV-2 S protein and ACE2 receptor using fluorescence correlation spectroscopy

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is initiated by an interaction between the human angiotensin-converting enzyme type 2 (ACE2) receptor and the SARS-CoV-2 spike (S) protein. This interaction closely resembles the mechanism of infection by SARS-CoV, the causative agent of SARS. However, in comparison, the interaction of the S1 subunit of SARS-CoV-2 with […]

Virus-like particles reveal unexpected mechanism for increased fitness and spread of SARS-CoV-2

Researchers in the United States have developed a new model for testing mutations in the four structural proteins of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19). Testing of the proteins for their effects on viral assembly, packaging and host cell entry provided a previously unanticipated explanation […]

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 […]

Researchers explore how N501Y mutation in SARS-CoV-2 increases viral transmissibility

Researchers at Erasmus University Medical Center in The Netherlands have explored how and why new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), have exhibited heightened infectivity. Study: Experimental evidence for enhanced receptor binding by rapidly spreading SARS-CoV-2 variants. Image Credit: Design_Cells / Shutterstock They suggest […]
