Virus News and Research

RSS

A virus is a microscopic infectious agent that can reproduce only inside a host cell. Viruses infect all types of organisms: from animals and plants, to bacteria and archaea. Since the initial discovery of tobacco mosaic virus by Martinus Beijerinck in 1898, more than 5,000 types of virus have been described in detail, although most types of virus remain undiscovered. Viruses are ubiquitous, as they are found in almost every ecosystem on Earth, and are the most abundant type of biological entity on the planet. The study of viruses is known as virology, and is a branch of microbiology.

New gene editing tool helps analyze the mysterious quirk of bacteria

While the CRISPR-Cas9 gene editing system has become the poster child for innovation in synthetic biology, it has some major limitations.

Study reveals SARS-CoV-2 spike protein can trigger long-term gene expression changes

According to the findings of a recent cell study, the SARS-CoV-2 spike protein can trigger long-term gene expression changes.

Study shows a possible link between pesticide exposure and increased COVID-19 susceptibility

Researchers have discovered a possible connection between increased vulnerability to COVID-19 infection and exposure to organophosphate pesticides.

Low-dose administration of MERS DNA vaccine protects against COVID-19

The Wistar Institute has developed a synthetic DNA vaccine candidate for Middle East respiratory syndrome coronavirus (MERS-CoV).

New AI model predicts targets for previously unmapped T cells against coronavirus

A research team has created an AI technique that can bind immune cells to their targets and uncouple the types of white blood cells that identify SARS-CoV-2.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

SARS-CoV-2 infection produces antibodies that can destroy infected cells

Research teams investigated the antibodies generated in people with symptomatic or asymptomatic SARS-CoV-2 infection.

Study identifies mechanism that enables SARS viruses to efficiently replicate in infected cells

Researchers have now identified how SARS viruses improve the production of viral proteins in infected cells such that new copies of the virus can be produced.

Study offers new ways to think about the immune system

Scientists have discovered new methods to interpret the immune system, as part of a new study reported in the Nature journal.

Sampling environmental DNA and RNA could help determine the presence of pathogens

Conventional techniques lack the potential to easily sample wider geographical areas and huge numbers of individuals.

Study finds raised levels of specific immune cells in asymptomatic people with COVID-19

The largest study of its type in the UK has identified differences in the immune response to COVID-19, between people with no symptoms, compared to those suffering a more serious reaction to the virus.

Interferon-stimulating genes control SARS-CoV-2 replication

Researchers have found a set of human genes that combat infection due to SARS-CoV-2, the virus responsible for causing COVID-19.

Antibodies may not inhibit SARS-CoV-2 variants from minks

It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells and represents the central point of attack for antibodies.

Supercomputer simulations reveal the behavior of dominant G form SARS-CoV-2 strain

Large-scale supercomputer simulations at the atomic level show that the dominant G form variant of the COVID-19-causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, compared to other variants.

Study reveals how some antibodies can effectively disable ebolaviruses

Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses--and now, scientists at Scripps Research have illuminated how these antibodies can disable the viruses so effectively. The insights may be helpful for developing effective therapies.

Ebola virus protein changes shape by using human RNA

The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape--and biologists are taught that defined shape dictates the protein's destined function. Tens of thousands of singular shapes drive the tens of thousands of needed functions.
