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.

How economic fallout due to COVID-19 puts global food security at risk

The ongoing COVID-19 pandemic has forced nations worldwide to implement unprecedented social measures to stem the rapid spread of the virus.

Re-engineering antibodies to fight SARS-CoV-2 infection

With millions of COVID-19 cases reported across the globe, people are turning to antibody tests to find out whether they have been exposed to the coronavirus that causes the disease.

Researchers show efficacy of phage cocktail therapy on wound infections

Australian researchers have shown how viruses can be used to save lives, developing the potential use of bacteriophages in bandages to treat life-threatening golden staph infections which may not respond to traditional antibiotics.

Understanding the structure of SARS-CoV-2 proteins may lead to novel drugs

COVID-19 is a disease caused by an RNA virus called SARS coronavirus 2 (SARS-CoV-2), that is, a virus that employs RNA to preserve its genetic data.

New methods to regulate enzymes involved in SARS-CoV-2 virus infection

A research team from the HSE University has designed innovative methods for controlling the expression of TMPRSS2 and ACE2 enzymes.

Rapid drug development yields potential treatment for yellow fever

Yellow fever, a hemorrhagic disease that is common in South America and sub-Saharan Africa, infects about 200,000 people per year and causes an estimated 30,000 deaths.

Cholesterol-lowering medication improves function of the coronary arteries

In a pilot study of people living with HIV or high levels of cholesterol, Johns Hopkins Medicine researchers found that a six-week course of a cholesterol-lowering medication improved the function of the coronary arteries that provide oxygen to the heart.

Study may lead to new therapeutic approaches against coronaviruses

The immune system secretes an endogenous protein that can strongly suppress coronaviruses, the pathogen that is responsible for causing the current pandemic.

Multiomics analysis reveals multiple characteristics of HIV-1-producing cells in vivo

For eradication of HIV-1 infection, it is important to elucidate the detailed features and heterogeneity of HIV-1-infected cells in vivo.

Supercomputer analyses point to a new pathway for COVID-19 inflammatory response

Analyses of lung fluid cells from COVID-19 patients conducted on a supercomputer point to patterns that may explain the body's response to SARS-CoV-2.

Scientists discover evolutionary lineage of SARS-CoV-2 virus

By reconstructing the evolutionary history of SARS-CoV-2, the virus that is responsible for the COVID-19 pandemic, an international research team of Chinese, European and U.S. scientists has discovered that the lineage that gave rise to the virus has been circulating in bats for decades and likely includes other viruses with the ability to infect humans.

Testing COVID-19 with FDA-approved drugs can improve outcomes for affected patients

A protein found in viruses that are responsible for causing SARS and COVID-19 infections is virtually identical.

Novel label-free imaging method can differentiate between quiescent and activated T cells

T cells are the immune soldiers at the frontlines of the battle with infiltrating pathogens that seek to cause disease. A new study published in Nature Biomedical Engineering describes a novel label-free imaging technique that can differentiate active T cells from those off duty.

EBV viral genome modifies the host epigenetic landscape to promote gastric cancer

The Epstein-Barr virus (EBV), one of the most common human viruses, is associated with about 8-10 per cent of stomach -- or gastric -- cancers, the third leading cause of cancer death globally.

28 Jul 2020

Heparin blocks SARS-CoV-2 infection in cell studies

In a test of antiviral effectiveness against the virus that causes COVID-19, an extract from edible seaweeds substantially outperformed remdesivir, the current standard antiviral used to combat the disease.

27 Jul 2020

Research identifies TLR7 gene that predisposes individuals to severe COVID-19

Current observations suggest that the coronavirus SARS-CoV-2 causes severe symptoms mainly in elderly patients with chronic disease.

27 Jul 2020

Experimental mRNA-based vaccine protects animals against SARS-CoV-2

An experimental messenger RNA (mRNA)-based vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) elicits protective immune responses in mice and non-human primates, researchers report on July 23rd in the journal Cell.

Coronavirus changes structure that prevents cells from detecting it

With an alarm code, we can enter a building without bells going off. It turns out that the SARS coronavirus 2 (SARS-CoV-2) has the same advantage entering cells. It possesses the code to waltz right in.

24 Jul 2020

Humans are mutating SARS-CoV-2, but natural selection enables the virus to bounce back

Scientists investigating the evolution of the virus that causes Covid19 say that its mutation seems to be directed by human proteins that degrade it, but natural selection of the virus enables it to bounce back. The findings could help in the design of vaccines against the virus.

New pathways that could help treat RNA viruses discovered

Researchers at the University of New Hampshire have identified new pathways in an RNA-based virus where inhibitors, like medical treatments, unbind.
