Virus News and Research

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.

Supercomputer simulations help uncover the mechanism for HIV replication

Viruses lurk in the grey area between the living and the nonliving, according to scientists. Like living things, they replicate but they don't do it on their own. The HIV-1 virus, like all viruses, needs to hijack a host cell through infection in order to make copies of itself.

B.1.1.7 variant of SARS-CoV-2 spreading quickly in the United States

The faster-spreading B.1.1.7 variant of SARS-CoV-2 first detected in the United Kingdom, the coronavirus that causes COVID-19, is quickly on its way to becoming the dominant variant of the virus in the United States, according to a study from scientists at Scripps Research and the COVID-19 test maker Helix.

Virus-cell interaction may explain the high infection rate of COVID-19 virus

Bioengineering scientists have now detected a formerly unknown interaction between the spike (or “S”) protein of SARS-CoV-2 and receptors in human cells.

Salivary gland cells could play role in SARS-CoV-2 virus transmission

Scientists have shown that SARS-CoV-2, the virus that causes COVID-19, can infect specific cells in the salivary gland in the mouth.

Antibody used for COVID-19 therapy can no longer inhibit new SARS-CoV-2 variants

Cell culture studies show that mutated viruses are less susceptible to inhibition by antibodies from recovered or vaccinated individuals.

Silencing a key protein to “domesticate” COVID-19 virus

When cells in the human body are invaded by a virus, they send a signal to adjacent cells to boost their antiviral defenses to stop the spread of infection.

Hormone drugs may help disarm coronavirus spike protein and stop disease progression

Hormone drugs that reduce androgen levels may help disarm the coronavirus spike protein used to infect cells and stop the progression of severe COVID-19 disease, suggests a new preclinical study from researchers in the Abramson Cancer Center at the University of Pennsylvania and published online in Cell Press's iScience.

New genetic engineering strategy largely reduces tau protein levels in Alzheimer’s animal model

A genetic engineering approach has helped scientists to drastically decrease the levels of tau protein.

Study shows how human viruses are better adapted to infect certain tissues

The world’s first systematic study has explained how SARS-CoV-2 and other human viruses are more adapted to infect specific types of tissues..

Key protein regulates cells’ innate defense mechanisms

Scientists from the University of Illinois Chicago (UIC) have found that heparanase (HPSE) is an important regulator of innate defense mechanisms of cells.

Study on AEG12 mosquito protein could lead to therapeutics against deadly viruses

Researchers have found that AEG12, a mosquito protein, strongly suppresses the class of viruses causing dengue, yellow fever, Zika, and West Nile.

Mutant peptides derived from SARS-CoV-2 hamper activation of CD8+ killer T cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

Three new COVID-19 variants can evade antibodies that act against original virus

New research at Washington University School of Medicine in St. Louis indicates that three new, fast-spreading variants of the virus that cause COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic.

SARS-CoV-2 can make itself unrecognizable to immune response by T-killer cells through mutations

The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection. In addition to antibodies, the so-called T-killer cells, are also responsible for detecting viruses in the body and eliminating them.

New ways proposed to overcome barriers in COVID-19 response

An international research team is calling for better consolidation of bioinformatics, viral genetics, and public health to allow for better pandemic responses.

Genomics study examines the impact of COVID-19 on care homes

Care homes are at high risk of experiencing outbreaks of COVID-19, the disease caused by SARS-CoV-2. Older people and those affected by heart disease, respiratory disease and type 2 diabetes - all of which increase with age - are at greatest risk of severe disease and even death, making the care home population especially vulnerable.
