Scientists explore structure of SARS-CoV-2 receptor-binding domain with G485R mutation

Researchers at the Bio21 Institute and Department of Biochemistry and Pharmacology, The University of Melbourne, studied the structure of a SARS-CoV-2 spike receptor-binding domain (RBD) with a G485R mutation. This mutation is a residue and not directly involved in interactions with the angiotensin-converting enzyme 2 (ACE2) residues but found in the Β1´/Β2' loop region.

How resistant is the SARS-CoV-2 Brazilian variant to antibodies?

Researchers based at the University of Oxford, UK, have shown that the P.1 Brazilian variant of SARS-CoV-2 is less resistant to natural or vaccine acquired antibody responses than the B.1.351, South African, variant, despite sharing convergent mutations.

The role of S-acylation in the enhancement of SARS-CoV-2 infectivity

A new study published on the bioRxiv server focuses on the role of S-acylation in the SARS-CoV-2 infection cycle. It has also characterized Spike acylation and has also identified other acylated viral proteins and host enzymes involved in the process of infection. Further, it has also revealed the importance of acylation in viral biogenesis and infection.

COVID-19-related lockdowns disproportionately impact women, UK study finds

An increasing number of research works have highlighted how women are disproportionately affected by the COVID-19 pandemic globally. Disease outbreaks impact men, women, and other genders differently.

Vaccinating the elderly first for COVID-19 saves most lives

A short paper authored by Goldstein, Cassidy, and Wachter, recently published online in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS), demonstrates mathematically that vaccinating the oldest first, in fact, ultimately saves both the most lives and the most life-years.

Risk of SARS-CoV-2 infection as UK schools reopened in 2020 was very low, say researchers

A study conducted by Public Health England has found that the risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – was very low among both students and staff as primary schools partially and fully reopened over the latter half of 2020.

Researchers explore difference in reactions to SARS-CoV-2 infection between children and adults

The COVID-19 pandemic has claimed over 2.67 million lives in less than a year and a half. However, it is uncommon in children, with less than 2% of the cases being in individuals below the age of 19. Most of these are of mild severity, with the clinical features of severe COVID-19 being rare in this age group.
