"Escape mutations" could help SARS-CoV-2 evade immune attack

Researchers in the United States have identified mutations within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – that can reduce antibody binding to the virus, potentially mediating its escape from immune attack.

RNA-binding proteins may suppress antiviral defenses against SARS-CoV-2

Conducted by researchers in South Korea at the Institute for Basic Science and the International Vaccine Institute, a new study published on the preprint server bioRxiv in November 2020 describes the many host proteins that bind with the ribonucleic acid (RNA) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and regulate the replication of the virus.

New findings could improve investigation of T cell response to COVID-19

Researchers in the United States have made an important discovery about the processing and presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral peptides that provides a better understanding of the immune response to coronavirus disease 2019 (COVID-19) and may help facilitate the design of improved vaccines.

Study shows SARS-CoV-2 cell receptor is a novel target of the gamma-secretase enzyme complex

Based on structural similarities with other targets of the gamma-secretase system, researchers from Columbia University Irving Medical Center in the United States show that the SARS-CoV-2 receptor for cell entry may be affected by its proteolytic activity. Their results are currently freely available in a bioRxiv preprint paper.

Antibody responses against seasonal common cold coronaviruses may protect against SARS-CoV-2

With the use of an accurate high throughput assay, researchers from the Weizmann Institute of Science and Magen David Adom Blood Services in Israel showed substantial inter-individual variability and antibody cross-reactivity against seasonal coronaviruses upon SARS-CoV-2 infection, with important implications for immune surveys and vaccines. The study is currently available on the medRxiv* preprint server.

Antibodies against prevalent endemic human coronaviruses may provide cross-protection to SARS-CoV-2

Researchers from Qatar have demonstrated that antibody repertoires against endemic human coronaviruses are qualitatively different in children when compared to the general adult population, as well as healthy adult blood bank donors – and they may also provide cross-protection against epidemic/pandemic strains.

An entire trimeric S-protein of SARS-CoV-2 is necessary for protective immune response

Researchers from Seattle Children's Research Institute and the University of Washington described a high-throughput and rapid technique to quantify circulating levels of functional antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), suggesting that the entire viral spike protein should be used to characterize the immune response. Their paper is currently available on the medRxiv* preprint server.
