Study provides new insights for understanding dynamic changes in immune responses to COVID-19

A KAIST immunology research team found that a specific subtype of macrophages that originated from blood monocytes plays a key role in the hyper-inflammatory response in SARS-CoV-2 infected lungs, by performing single-cell RNA sequencing of bronchoalveolar lavage fluid cells.

‘Wisdom and fear’ lead 90% of U.S. seniors to covid vaccines

Amid the latest surge in covid-19 cases and hospitalizations, the United States on Tuesday hit a milestone that some thought was unattainable: 90% of people 65 and older are at least partly vaccinated against the disease.

Nasal version of AstraZeneca SARS-CoV-2 vaccine prevents infection in animal models

Scientists evaluate the use of ChAdOx1 nCoV-19 as a potential intranasal (IN) vaccine candidate in hamster and rhesus macaque models.

Study shows COVID-19 organ-specific outcomes depend on anti-spike glycoprotein antibodies

A recent study from the University of Rochester reveals how the biodistribution kinetics and the affinity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for many different organs in the human body can be affected by antibodies targeting viral spike glycoprotein. The paper is currently available on the bioRxiv* preprint server while it undergoes peer review.

Flagging potential molecular predictors of response to biological therapies in ulcerative colitis

Several individuals suffering from bowel diseases like ulcerative colitis fail to respond to conventionally used biologic therapies.

Study sheds light on oral vaccine failure in mouse model of chronic gut disorder

A chronic gut disorder that occurs in regions with poor sanitation disrupts intestinal immune responses and impairs oral vaccine effectiveness in a mouse model of the disease, according to research led by UPMC Children's Hospital of Pittsburgh and University of Pittsburgh School of Medicine scientists.

Unvaccinated and vaccinated have similar viral load in communities high in SARS-CoV-2 delta

The findings reveal that vaccinated and unvaccinated individuals exhibit similar viral loads following delta infection and that vaccine breakthrough cases have the potential to transmit infection to others. The study is currently available on the medRxiv* preprint server.

National Qatari study shows vaccination reduces risk of spreading SARS-CoV-2 infection

A team of scientists from Qatar and the United States has recently studied the viral transmission potential of individuals with primary severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, reinfection, or vaccine breakthrough infection.

CHOP researchers identify two proteins that could be used for a potential NTHi vaccine

Scientists at Children's Hospital of Philadelphia have identified two proteins that could be used for a potential vaccine against nontypeable Haemophilus influenzae (NTHi).

Study shows efficacy of Pfizer-BioNTech and Moderna vaccines against SARS-CoV-2 delta variant

Researchers in Singapore have conducted a study showing that the messenger RNA- (mRNA) based coronavirus disease 2019 (COVID-19) vaccines developed by Pfizer-BioNTech and Moderna are highly effective at protecting against symptomatic and severe disease following infection with the rapidly spreading B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Cancer vaccine reduces tumor burden, improves survival in animal model of Lynch syndrome

A new strategy for developing vaccines against cancer showed promise in a proof-of-concept study led by scientists at Weill Cornell Medicine, NewYork-Presbyterian and Heidelberg University Hospital.

Researchers discover titanium oxide nanoparticle that recognizes SARS-CoV-2’s non-structural protein 1

A pioneering study reports on the interaction of a tailored titanium oxide nanoparticle (NP) with the full-length SARS-CoV-2 non-structural protein 1 (nsp1). This should be of value in developing new therapeutic tools against coronaviruses that act by targeting their proteins. It could also help map the structure of activated proteins.

Polyuridine sequence of mouse coronavirus can be targeted to prevent host cell death

A new study reports the use of a modified deoxyribonucleic acid (DNA) oligonucleotide that has a 3’ polyadenine (polyA) tail to bind to the 5’-polyU tract in the mouse coronavirus (MHV-A59). Treatment of mouse cells infected with MHV-A59 with this molecule led to a marked reduction in cell deaths.

2 Aug 2021

Could novel biosensors facilitate SARS-CoV-2 antiviral drug research?

An intriguing new study presents a novel approach to biosensor-based evaluation of promising drugs that could inhibit the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via its 3C-like protease (3CLpro), a viral protease.

2 Aug 2021

Public and private SARS-CoV-2 T cell receptors may be crucial for pan-coronavirus vaccines

Researchers have just established a structural basis for two spike glycoprotein epitopes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are restricted to human leukocyte antigen (HLA) A2 molecules. More specifically, they are involved in the presentation of antigenic peptides to specific T lymphocytes and recognized by public and private T cell receptors. The research is currently available on the bioRxiv* preprint server.

Amid covid booster debate, West Virginia to check immunity of vaccinated nursing home residents

West Virginia raced ahead of the country last winter to get people in nursing homes vaccinated against covid-19, but with cases and hospitalizations on the rise again, state officials want to know whether immunity levels are falling for residents who had their shots.
