How SARS-CoV-2 infects the brain

While there is no official explanation on how SARS-CoV-2 travels to the brain, a new review published in the journal Fluids and Barriers of the CNS concluded that there is insufficient evidence on COVID-induced neurological problems coming from a direct invasion of SARS-CoV-2 into the brain.

Exhausted T cells linked to increased risk of COVID-19 mortality

New research led by Nadia R. Roan of Gladstone Institutes and the University of California, San Francisco, finds a correlation between high numbers of inflammatory CXCR4+ T cells and regulatory T cells specific to SARS-CoV-2 and dying from infection. In contrast, people who recovered from severe COVID-19 illness were more likely to have many SARS-CoV-2-specific T cells that perform homeostatic proliferation.

Study proves effectiveness of Artemisia annua against SARS-CoV-2 in vitro

A multinational research group has been the first to show the excellent activity of artemisinin-based treatment against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human cell lines – including a specific type of lung cells. Their findings were recently published in the journal Scientific Reports.

Past SARS-CoV-2 infection enhances mRNA vaccine-induced neutralization of variants of concern

Researchers in the United States have conducted a study suggesting that individuals previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibit better neutralizing activity against variants of concern following vaccination against coronavirus disease 2019 (COVID-19) than previously uninfected vaccinees.

Neutralizing antibodies persist against SARS-CoV-2 at least a year after infection

Researchers in Finland have conducted a study showing that the neutralizing bodies generated following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – generally persist for at least a year.

Iodine derivative kills SARS-CoV-2 within 90 sec

A recent study estimated the virucidal efficacy of EID for oral/nasal decontamination of known or suspected cases of COVID-19.

Researchers develop new tool to simulate the impact of SARS-CoV-2 strains and vaccines

The MOMAT research group from Universidad Complutense de Madrid has worked with Universidad de Almería, to develop a mathematical model that simulates the impact of SARS-CoV-2 strains and vaccines together, combined with many other biological and social processes in the propagation of COVID-19.

Thai study looks at CoronaVac vaccine vs. natural immunity to SARS-COV-2 variants

A new study evaluates the efficacy of vaccine- and infection-induced antibodies against SARS-CoV-2 variants.

Antibody levels remain high nine months after SARS-CoV-2 infection, study shows

Testing of an entire Italian town shows antibody levels remain high nine months after SARS-CoV-2 infection, whether symptomatic or asymptomatic.

Scientists deconstruct the protein-based machine responsible for SARS-CoV-2 replication

In February 2020, a trio of bio-imaging experts were sitting amiably around a dinner table at a scientific conference in Washington, D.C., when the conversation shifted to what was then a worrying viral epidemic in China.

Study: Second dose of COVID-19 vaccine induces a powerful boost to the immune system

The second dose of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a study led by investigators at the Stanford University School of Medicine.

Novel coronavirus found in UK horseshoe bats

A coronavirus related to the virus that causes Covid-19 in humans has been found in UK horseshoe bats - according to new collaborative research from the University of East Anglia, ZSL (Zoological Society of London), and Public Health England (PHE).

Study suggests children develop short-term humoral immunity following SARS-CoV-2 infection

A single-center, cross-sectional epidemiological survey conducted in Israel has recently pointed out that antibodies induced by natural SARS-CoV-2 infection in children start declining just after 4 months of acute infection. However, their seropositivity rates are not impacted by school reopening. The study has recently been published in the journal Acta Paediatrica.

Dysbiosis in gut microbiota may cause severe secondary infection in COVID-19 patients

An interesting study led by scientists in the U.S. has recently revealed that the microbial community in the gut is directly affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that virus-mediated gut microbiome dysbiosis may cause severe secondary infections in coronavirus disease 2019 (COVID-19) patients. The study is currently available on the bioRxiv* preprint server.

Do mRNA-based COVID-19 vaccines induce memory T cell response similar to natural infection?

A team of scientists from the United States has recently compared the epitope-specific T cell response after natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or vaccination in both naïve and previously infected individuals.

Analysis shows the amount of testing for COVID-19 matters more than the sensitivity of the tests

Results from sensitive RT-PCR tests can be similar in accuracy to the less sensitive antigen tests, providing valuable insight for testing policies.

Stronger and longer SARS-CoV-2 RBD-ACE2 binding associated with glycans in new study

A new study has been published on the bioRxiv* preprint server, which focuses on the mechanism behind the binding of SARS-CoV-2 with the host receptor, using a molecular dynamics approach. The authors of this study aim to highlight the role of glycans in initiating the interaction between S and ACE2.

Researchers conduct molecular dynamic study of SARS-CoV-2 spike glycoprotein and human skin model interactions

Currently, there is a lack of understanding of the physico-chemical features of the interaction between coronaviruses and different surfaces. However, new research has been published on the bioRxiv* preprint server that documents the molecular details of the interaction between the human skin and SARS-CoV-2.

Health impacts of lockdowns unlikely to be worse than the impact of COVID-19 pandemic

Although lockdowns are undoubtedly associated with health harms, their impact on health is unlikely to be worse than the impact of the COVID-19 pandemic itself, concludes a review published in the online journal BMJ Global Health.

Inhibition of SARS-CoV-2 by bentonite-based nasal spray

Therefore, the nose is an important target for prophylaxis and also for therapy. In a recent study posted to the bioRxiv* preprint server, Fabio Fais et al. developed a safe and easy-to-use nasal spray, AM-301, a medical device marketed as Bentrio, to protect against infection by SARS-CoV-2 and potentially other viruses.
