Research suggests toll-like receptor 4 appears to play role in severe COVID

A group of researchers re-evaluated their previously proposed hypothesis, which stated that the TLR4 activated by the spike glycoprotein S1 domain increases ACE2 expression and, thereby, aids in COVID-19 infection.

Modeling the spread and development of SARS-CoV-2 outbreaks in the US

In a research paper recently uploaded to the medRxiv* preprint server, high-resolution contact data is utilized to characterize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in the USA, considering infections' mobility and seasonality and vaccination status seroprevalence within the population.

Direct evidence in hamsters shows SARS-CoV-2 is airborne

Evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted without contact by respiratory droplets and aerosols bearing the virus when coughing, sneezing, speaking, and breathing. The virus has been cultured from aerosols collected nearby COVID-19 patients, and such aerosols can linger in still air for hours.

Role of neutrophil-epithelial interactions in SARS-CoV-2 infection

Researchers discuss the relationship between airway neutrophils and SARS-CoV-2 infection to determine the impact that neutrophils have on COVID-19.

Utah warns of Delta variant eroding COVID vaccine effectiveness

A recent study finds a reduction in vaccine effectiveness against COVID-19 in Utah corresponding to the spread of the Delta variant in the region.

Certain intestinal bacteria induce cross-reactive IgA responses to the SARS-CoV-2 spike RBD

A new study finds that human gut bacteria can induce antibodies of the immunoglobulin A (IgA) subtype that cross-react with the SARS-CoV-2 spike RBD.

World-first trial of third dose COVID-19 booster vaccine shows improved protection in transplant patients

Scientists with the Ajmera Transplant Centre at UHN have conducted a first-in-the-world randomized placebo-controlled trial of third dose COVID-19 booster vaccine for transplant patients that shows substantially improved protection.

Enzyme acts as a sensor to find the hiding spots of viruses

While some types of RNA viruses cloak themselves to hide inside a cell and create copies of themselves, a "detective enzyme" might be attuned to their whereabouts. A slight variation in their genomic code gives some people's cells the capacity to produce this sensor.

Understanding how to regulate key enzyme may lead to new treatments for cancers, viral infections

A new study led by University of California, Irvine (UCI) researchers identifies two ways in which APOBEC3A - a vital enzyme that is responsible for genetic changes resulting in a variety of cancers while protecting our cells against viral infection - is controlled.

UC Davis joins with Pfizer for COVID-19 booster vaccine trial

As COVID-19 booster shots begin for those with compromised immune systems, researchers at the UC Davis School of Medicine continue to collect data from clinical trial participants.

Emergency Department sees a significant increase in COVID-19 cases during August 2021

The Emergency Department (ED) at UC Davis Medical Center saw a 33% increase in COVID-19 patients during the first week of August, providing treatment for 107 patients, up from 80 patients the week before.

‘I don’t want to risk my life for a paycheck’: Immunosuppressed people grapple with returning to work

Elizabeth Groenweghe got a kidney transplant 14 years ago. She now takes several medications to prevent her body from rejecting her transplant organ. But these medications also weaken her immune system, putting her at higher risk of becoming seriously ill if she catches covid-19.

L452R mutations may have triggered the emergence of several COVID-19 variants

Most of the recently risen coronavirus variants of interest or concern -- delta, kappa, epsilon, iota and lambda -- are universally carrying a mutation in amino acid L452 of the Spike protein that helps the virus bind to host cells.

WHO outlines the next series of studies on the origins of SARS-CoV-2 virus

Since the start of the COVID-19 pandemic, WHO has been working with the Member States and the scientific community to better understand how this pandemic began so that we can be better prepared for the next one.

Pfizer CEO to public: Just trust us on the covid booster

Pfizer CEO Albert Bourla was confident in June about the ability of his company's vaccine to protect against the highly contagious delta variant, as it marched across the globe and filled U.S. hospitals with patients.

Discovery of highly potent neutralizing monoclonal antibodies against SARS-CoV-2

A new study published in the journal Nature Communications has reported two neutralizing antibodies, namely, nCoVmab1 and nCoVmab2, which are potent against SARS-CoV-2.

How replication and recombination contribute to emergence of SARS-CoV-2 variants

The coronavirus disease 2019 (COVID-19) pandemic has been caused by the rapid outbreak of a novel coronavirus, namely, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). SARS-CoV-2 was first reported in late December 2019 in Wuhan, China. Since then, the virus has already claimed more than 4.3 million lives worldwide.

Advances in plant-made vaccines revive interest in plant-produced pharmaceuticals and edible drugs

Recent progress in developing and testing plant-made vaccines has revived interest in plant-produced pharmaceuticals, including edible drugs, for human use. Advances in technology and manufacturing could boost the uptake of therapeutics made in this way, say Hugues Fausther-Bovendo and Gary Kobinger in this Perspective.

SARS-CoV-2 variants containing L452R spike mutation more resistant to antibody-mediated neutralization

A team of scientists from Frankfurt, Germany, has recently explored the efficacy of vaccine- or infection-induced antibodies and therapeutic monoclonal antibodies in neutralizing kappa and delta variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Optical nanoscopy reveals how SARS-CoV-2 infection alters human airway cells

How do viruses reorganize host cells with spatial and molecular specificity? Researchers from the Netherlands provided new insights in a recent study posted to the bioRxiv* preprint server, where they use optical nanoscopy to look at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-triggered changes in primary human airway cells.
