Neutralizing the SARS-CoV-2 sugar coat

Researchers identify two sugar-binding proteins that impede the viral entry of circulating SARS-CoV-2 variants. The team, spearheaded by researchers at IMBA — Institute of Molecular Biotechnology of the Austrian Academy of Sciences — may have found the “Achilles’ heel” of the virus, with potential for pan-variant therapeutic interventions. The findings are now published in the… Continue reading Neutralizing the SARS-CoV-2 sugar coat

Shared antibodies may push COVID-19 variants, study finds

Researchers at Vanderbilt University Medical Center have found that people recovering from COVID-19 and those vaccinated against the causative virus, SARS-CoV-2, produce identical clones, or groups, of antibody-producing white blood cells. Their discovery, reported this week in the journal Cell Reports, sheds light on the selection pressures driving the emergence of SARS-CoV-2 variants that have… Continue reading Shared antibodies may push COVID-19 variants, study finds
