SARS-CoV-2 launches multipronged attack against host cell protein synthesis, study finds

An interesting new study throws a flood of light on how SARS-CoV-2 accomplishes its mission to infect and replicate within host cells while evading the host immune response.

Digital warm-start CRISPR assay enables sensitive quantitative detection of SARS-CoV-2 in clinical samples

In a recent medRxiv* preprint paper, researchers from the University of Connecticut Health Center in the United States unveil their digital warm-start CRISPR (WS-CRISPR) method for stringent and sensitive quantitative detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in clinical samples of patients with coronavirus disease (COVID-19).

Repeat infection following COVID-19 recovery may not pose risk to close contacts

Researchers in China have conducted a study suggesting that people who have recovered from coronavirus disease 2019 (COVID-19) may not pose a risk to close contacts if they become reinfected with the causative agent severe acute respiratory syndrome coronavirus (SARS-CoV-2).

Hydrogen therapy may help severely ill COVID-19 patients

Researchers from the Department of Critical Care Medicine, Sichuan Provincial People's Hospital, Chengdu in China, have explored the possibility of using hydrogen therapy on severely ill COVID-19 patients. The team published their study's findings, titled "Hydrogen: A Potential New Adjuvant Therapy for COVID-19 Patients," in the latest issue of the journal Frontiers in Pharmacology.

New rapid algorithm could help trace hospital-derived SARS-CoV-2 infections

A new study reports a rapid method that uses two different routes to swiftly trace the onset of infection to a putative hospital source. This could be immensely helpful for preventing and controlling infection, once validated.

Ultrasound reveals a possible role of SARS‐CoV‐2 in acute testicular infection

A single-center study from Wuhan in China presents ultrasound imaging evidence supporting the notion that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause infection of the testis or epididymis – and put patients at risk for further complications. The paper can be found in the Journal of Ultrasound in Medicine.

COVID-19 treatments for people with early infection should be prioritized

COVID-19 treatments for people with early infection are needed urgently, according to a JAMA Viewpoint article by National Institute of Allergy and Infectious Diseases (NIAID) Director Anthony S. Fauci, M.D., and colleagues.

How SARS-CoV-2 blocks immune response

An international research team has confirmed the mechanism by which the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). Their article titled, “SARS-CoV-2 Orf6 hijacks Nup98 to block STAT nuclear import and antagonize interferon signaling,” is published in the journal Proceedings of the National Academy of Sciences.

An analysis of genetic diversity of D614G mutation in SARS-CoV-2

A new study published in the preprint server bioRxiv in November 2020 reports that the effect of the mutation is minimal, in terms of pathogenicity or altered response to neutralizing antibodies elicited against the native virus strain.

16 new lineages of SARS-CoV-2 emerge in South Africa despite lockdown

Published in a recent medRxiv* paper, researchers from South Africa, the United Kingdom, and Brazil found that these mutations in SARS-CoV-2 lineages are localized to South Africa. These unique strains, not found elsewhere in the world, are thought to have contributed around 42% to the country's total infection rate.

Study reveals molecular mechanism that increases the invasiveness of radioresistant cancer cells

Scientists have revealed the molecular mechanism regulating the trafficking of lysosomes that increases the invasiveness of radioresistant cancer cells following radiotherapy.

SARS-CoV-2 is mainly spread in households and household-like settings

Ten months into the coronavirus disease (COVID-19) pandemic, health experts have a good understanding of how the virus spreads. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads through respiratory droplets and aerosols and enters the body through the mouth, nose, and eyes.

Nasal spray formulation of ivermectin for COVID-19 shows promise in pigs

Researchers in Argentina have conducted a pre-clinical study demonstrating the safety and pharmacokinetic performance of a new nasal spray formulation designed to suppress the replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

26 Oct 2020

Antigenic imprinting of sarbecovirus

A recent study published on the preprint server bioRxiv* in October 2020 shows that the design of a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) must consider the prior history of exposure to coronaviruses since these affect the antibody response to the virus.

Comparative analysis reveals common vulnerabilities across coronaviruses

Three lethal human respiratory syndromes associated with coronavirus (CoV) infections have emerged in the past two decades. They are severe acute respiratory syndrome (SARS) in 2002, Middle East respiratory syndrome (MERS) in 2012, and coronavirus disease 2019 (COVID-19) in 2019.
