Blocking function of a blood-clotting protein may help prevent or treat periodontal disease

Blocking function of a blood-clotting protein prevented bone loss from periodontal (gum) disease in mice, according to research led by scientists at the National Institute of Dental and Craniofacial Research, part of the National Institutes of Health.

Impact of the rapid spread of the SARS-CoV-2 Omicron variant in Southern Africa

A new study has focused on the genomic profile and early transmission dynamics of Omicron. This study revealed the dominance of the Omicron variant in regions with high levels of population immunity.

Researchers reveal an unrecognized pathway promoting long-term survival of T cells

They are at the forefront in the fight against viruses, bacteria, and malignant cells: the T cells of our immune system. But the older we get, the fewer of them our body produces.

Exploring why children have milder COVID-19 infections compared to adults

A new study has revealed that an activated pre-exposure innate interferon response in airways together with significantly reduced systemic interferon-stimulated populations are associated with relatively milder severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children.

Exploring immunity and severe disease caused by the SARS-CoV-2 Omicron variant

A new study describes the findings of a seroprevalence survey intended to establish the infection rates and the incidence of severe COVID-19 through December 15, 2021, in Gauteng, a crowded province that compresses a quarter of the country’s people into less than 2% of its area.

Assessing the clinical severity of the SARS-CoV-2 Omicron variant

A recent preprint examines the proportion of Omicron infection and the risk of severe disease with this variant of SARS-CoV-2.

Pediatric hospital admissions rise with omicron SARS-CoV-2 variant

A new study examines the impact of the Omicron variant on hospitalizations among children in South Africa.

23 Dec 2021

Study reports that children develop sustained cross-reactive adaptive immunity against coronaviruses

A new study shows that both antibody and cellular arms of the adaptive immune response against SARS-CoV-2 are displayed strong, sustained, and cross-reactive against other coronaviruses, in young children than the immune responses in adults.

The transmission dynamics of SARS-CoV2 Omicron variant

In a recent study posted to the medRxiv* preprint server, researchers developed a coronavirus disease (COVID-19) model-inference system in South Africa to determine transmission dynamics and immune evasion associated with severe acute respiratory syndrome-associated coronavirus disease (SARS-CoV-2) Omicron variant.

How the SARS-CoV-2 Delta variant grew to dominate the UK epidemic

Researchers examine SARS-CoV-2 genomes in England to evaluate the effectiveness of COVID-19 policies.

Decline in protection against SARS-CoV-2 Omicron in prior infected and fully vaccinated

In a recent study posted to the medRxiv* preprint server, researchers investigated the distribution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta and Omicron variants among coronavirus disease 2019 (COVID-19) positive individuals who were either naive, fully vaccinated, or had a previous infection to further investigate possible escape from vaccine- or infection-induced immunity by Omicron compared to Delta.

Scientists develop methods to quantify the transmissibility of new COVID-19 variants

As the discovery of the new omicron variant illustrates, new COVID-19 variants will continue to regularly emerge.

T-cell response to Omicron after an mRNA COVID vaccine booster

In a recent prospective observational study posted to the medRxiv* preprint server, researchers determined Omicron variant-associated T cell responses before and after a third dose of messenger ribonucleic acid (mRNA) vaccination against coronavirus disease (COVID-19) in anti-CD20-treated multiple sclerosis (MS) patients.

Infect, replicate, and rapidly mutate: Computational virus modeling study

A new bioRxiv* preprint study led by Barbara A Jones of IBM Research-Almaden in San Jose, California, used computational modeling to investigate how viruses rapidly mutate as well as how they respond or adapt to different host conditions. They observed a range of behaviors from glassy dynamics, bimodal quasispecies distributions, and periodic steady states.
