How fast has the Omicron strain been spreading in South Africa?

Scientists have shown the exponential growth of the Omicron strain found in Gauteng. They reported the doubling time of this strain to be equal to 3.38 days by analyzing its growth from November 8 to December 5, 2021. Based on the mutation accumulation profile, researchers revealed that this strain began to diverge between October 28 and November 5, 2021.

15 Dec 2021

SARS-CoV-2 patients exhibit high specialized pro-resolving molecule serum levels

In a new study, researchers compared the serum levels of bioactive lipids in a cohort of 50 in-patients who had confirmed symptomatic SARS-CoV-2 infection with that of a control group.

Machine learning method for determining impact of mutations in the SARS-CoV-2 RBD on binding and antibody escape

Deep mutational learning (DML) is a technique developed by researchers from multiple institutions that combines experimental yeast display screening of RBD mutagenesis libraries with deep sequencing and machine learning.

14 Dec 2021

Omicron variant may strike double vaccinated

Largely, scientists are skeptical that the Omicron variant can infect vaccinated individuals. However, a new study published on the medRxiv* preprint server has conducted neutralization assays using an Omicron isolate obtained from patients residing in the United Kingdom.

Cellular properties of SARS-CoV-2 spike protein RBD in virus-infected African green monkey kidney epithelial cells

Researchers from the Biological Defence Programme of Singapore have investigated six of these antibodies.

13 Dec 2021

Genetic-code expansion technique to potentially create next-generation vaccine candidate

A new experiment devised a novel method to manipulate virulent viruses in conventional laboratories and validated the prophylactic effect of this method in two mouse models.

13 Dec 2021

Study demonstrates SARS-CoV-2 ORF6 localization and interferon antagonism as independent events

Researchers deploy mutagenesis studies to investigate the relationship between ORF6 localization and IFN antagonism.

12 Dec 2021

Even if SARS-CoV-2 Omicron evades antibodies, immunity still exists

Researchers determined antibody-mediated neutralization efficacy against the authentic SARS-CoV-2 Omicron variant.

12 Dec 2021

First locally acquired infection of Omicron variant confirmed in San Diego

Officials at the San Diego County Health and Human Services Agency, working in collaboration with scientists at University of California San Diego and Scripps Research, have announced the second confirmed case — and first locally acquired infection — of the Omicron variant of SARS-CoV-2, the virus that causes COVID-19.

12 Dec 2021

Mutational landscape of SARS-CoV-2 Omicron variant

New research suggests mutations on the receptor-binding domain of the Omicron variant exert indirect effects that reduce antibody binding to epitopes and promote immune evasion.

10 Dec 2021

Study finds sarbecoviruses circulating in wildlife outside Asia can infect human cells

A recent study tested the RBD of 2 sarbecoviruses found in Russian horseshoe bats and other clades 3 viruses for their ability to invade the human cell.
