NIH scientists develop new sample preparation method to detect SARS-CoV-2

Scientists at the National Institutes of Health (NIH) have developed a new sample preparation method to detect SARS-Cov-2, the virus that causes COVID-19.

Penn researchers reveal complex details of T-cell responses to mRNA COVID-19 vaccines

Messenger-RNA (mRNA) vaccines against the coronavirus that causes COVID-19 provoke a swift and strong response by the immune system's T cells-;the heavy armor of the immune system-;according to a study from researchers in the Perelman School of Medicine at the University of Pennsylvania.

The newest disease detection tool for covid and beyond: Poop

Since reopening campus at the University of California-San Diego last summer, university officials have relied on the tried-and-true public health strategies of testing and contact tracing. But they have also added a new tool to their arsenal: excrement.

In rural America, twisting arms to take a covid vaccine first takes trust

Lee Wright was hard at work, constructing a nail salon near the city's abandoned hospital, when Jody Johnson stopped by to introduce himself on a recent afternoon.

Obtained SARS-CoV-2 immunity, naturally or via vaccination persists 12 months

In a research paper recently uploaded to the preprint server medRxiv* by Havervall et al. (August 12th, 2021), neutralizing antibody titers towards wild-type SARS-CoV-2 and several variants of concern in individuals having either been vaccinated or infected with mild COVID-19 one year earlier are assessed, finding a reduced neutralization capacity against some strains.

Response to a third SARS-CoV-2 vaccine dose amongst immunocompromised

In a research paper recently uploaded to the preprint server medRxiv* by Schrezenmeier et al. (August 12th, 2021) the potential benefit of three vaccine doses in either a homogenous or heterogeneous dosing regimen amongst kidney transplant patients is assessed, finding that the search for viable vaccination approaches amongst these patients remains an urgent medical need.

Researchers assess the genetic features of T-cell immunity development to SARS-CoV-2 variants

The continuing emergence of new SARS-CoV-2 mutations allows the virus to spread more effectively and evade antibodies. However, it is unclear whether new strains are capable of evading T-cell immunity-; one of the body's main lines of defense against COVID-19.

More than one in ten COVID-19 patients acquired the virus in a hospital during UK's first wave

More than one in ten COVID-19 patients in 314 UK hospitals caught the infection in hospital during the first pandemic wave say researchers conducting the world's largest study of severe COVID-19.

Clinical discussions on diet-associated NAFLD and COVID-19 mortality risk among PPI users

The August issue of The American Journal of Gastroenterology includes clinical discussions of diet-associated NAFLD risk and increased risk of mortality from COVID-19 among PPI users.

Primate study shows benefit of mRNA vaccine booster shot against SARS-CoV-2 variants

In a recent bioRxiv* preprint research paper, a large group of US scientists demonstrate how a booster dose of the mRNA-1273 vaccine can substantially improve both the potency and range of neutralizing antibody responses and mediate protection against upper and lower airway infection by a range of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern – even those relatively resistant to in vitro neutralization.

New system combines computer software and cryo-EM to determine 3D structures of RNA-only molecules

The single-stranded genetic material RNA is best known for guiding the assembly of proteins in our cells and carrying the genetic code for viruses like SARS-CoV-2 and HIV.

SARS-CoV-2 Spike may trigger production of antibodies that cross-react with human thrombopoietin to induce thrombocytopenia

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infected individuals often suffer from thrombocytopenia, a condition associated with low platelet counts. The cytokine thrombopoietin regulates platelet count. Previous studies have reported that thrombocytopenia can increase the coronavirus disease 2019 (COVID-19) mortality rate by about five times.

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.

COVID-19 prevention strategies for the U.S. food industry

A new study discusses the measures that should be taken to mitigate the risk of COVID-19 among food industry workers.

15 Aug 2021

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.

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.
