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.

Scientists discover new antiviral drug against paramyxovirus

A new antiviral drug that is effective against a broad range of human pathogens in the paramyxovirus family, such as the human parainfluenzaviruses and measles virus, has been discovered by researchers in the Institute for Biomedical Sciences at Georgia State University.

New mutation in common flu subtype helps evade immune response

Strains of a common subtype of influenza virus, H3N2, have almost universally acquired a mutation that effectively blocks antibodies from binding to a key viral protein, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.

Study may provide a therapeutically safer strategy for gene editing

The CRISPR gene editing system is a robust tool specifically developed for the targeted editing of genomes. While this tool has considerable therapeutic potential, it is associated with improper editing of “off-target” sites.

Structural analysis of SARS-CoV-2 spike protein offers clues about the virus' evolution

Researchers at the Francis Crick Institute have characterized the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.

Researchers identify protective antibodies for rare, polio-like disease in children

Researchers at Vanderbilt University Medical Center, Purdue University and the University of Wisconsin-Madison have isolated human monoclonal antibodies that potentially can prevent a rare but devastating polio-like illness in children linked to a respiratory viral infection.

Study highlights the role of hematopoietic immune cells in gene regulation

More often, the human body is viewed as a “machine” containing specialized components: immune cells protect against pathogens, organs contribute physiological functions, and soft tissue and bones give structure.

Mineral-coated microparticles are better vehicles for promising mRNA-based therapy

University of Wisconsin-Madison researchers have developed a safer and more efficient way to deliver a promising new method for treating cancer and liver disorders and for vaccination -- including a COVID-19 vaccine from Moderna Therapeutics that has advanced to clinical trials with humans.

COVID-19 makes platelets 'hyperactive' and more prone to form deadly blood clots

Changes in blood platelets triggered by COVID-19 could contribute to the onset of heart attacks, strokes, and other serious complications in some patients who have the disease, according to University of Utah Health scientists.

Scientists develop CRISPR-assisted method to detect RNA-binding proteins in living cells

While scientists still don't fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation.

Wild strains of salmonella find a backdoor entry into plants

As the world wrestles with the coronavirus (COVID-19) pandemic, which arose after the virus jumped from an animal species to the human species, University of Delaware researchers are learning about new ways other pathogens are jumping from plants to people.

Study shows promise for developing novel COVID-19 therapeutics

A protein known as polymerase is used by SARS-CoV-2—the coronavirus that is responsible for causing the worldwide COVID-19 pandemic—to replicate its genome within the infected human cells.

Even the sickest COVID-19 patients produce T cells to fight back the virus

A new study from researchers at La Jolla Institute for Immunology and Erasmus University Medical Center shows that even the sickest COVID-19 patients produce T cells that help fight the virus.

Lab-grown 'mini-brains' can be infected by SARS-CoV-2 virus

A multidisciplinary team from two Johns Hopkins University institutions, including neurotoxicologists and virologists from the Bloomberg School of Public Health and infectious disease specialists from the school of medicine, has found that organoids (tiny tissue cultures made from human cells that simulate whole organs) known as "mini-brains" can be infected by the SARS-CoV-2 virus that causes COVID-19.
