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.

Study explains the compatibility of bacteria and virus in the human gut

The proverb “all things in moderation” holds good not only for food and drink but also for the cluster of microorganisms found inside the human gut.

Advanced cryo-EM reveals stunning details of viral RNA replication complex structure

For the first time, scientists at the Morgridge Institute for Research have generated near atomic resolution images of a major viral protein complex responsible for replicating the RNA genome of a member of the positive-strand RNA viruses, the large class of viruses that includes coronaviruses and many other pathogens.

UC Davis Health tests new antibody combination as potential treatment for COVID-19

Timothy Albertson, chair of internal medicine and specialist in pulmonary and critical care, is leading efforts at UC Davis Health to test a new antibody cocktail (REGN-COV2) as a prevention and treatment for COVID-19.

Study shows how the coronavirus disarms the body’s innate immune system

Scientists have established how SARS-CoV-2 suppresses the production of proteins in infected cells and how this virus effectively disarms the immune system.

Researchers find a way to prevent SARS-CoV-2 virus from binding to cells

On July 1, the Texas A&M Engineering Experiment Station's (TEES) National Center for Therapeutics Manufacturing (NCTM) received funding from the National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL) to help find a way to prevent the SARS-CoV-2 virus from binding to cells, protecting people from future infections.

Small, compact Cas proteins found in bacteriophages are ideal for gene editing

The DNA-cutting proteins central to CRISPR-Cas9 and related gene-editing tools originally came from bacteria, but a newfound variety of Cas proteins apparently evolved in viruses that infect bacteria.

SARS-CoV-2 protein effectively shuts down host protein production, shows study

A detailed study of a SARS-Cov-2 protein, Nsp1, with a central role in weakening the host anti-viral immune response shows that it effectively shuts down production ofproteins in the host.

Using blood samples to detect positive COVID-19 cases in 20 minutes

World-first research by Monash University in Australia has been able to detect positive COVID-19 cases using blood samples in about 20 minutes, and identify whether someone has contracted the virus.

Type 1 interferon deficiency in the blood could be a hallmark of severe COVID-19

Approximately 5% of people with Covid-19 progress to a severe or critical form, including the development of severe pneumonia that progresses to acute respiratory distress syndrome.

New method reveals the dynamics of HIV Gag-protein lattice structure

Viruses are scary. They invade our cells like invisible armies, and each type brings its own strategy of attack. While viruses devastate communities of humans and animals, scientists scramble to fight back.

Study uncovers virus-specific T cell immunity in recovered COVID-19 and SARS patients

The T cells, along with antibodies, are an integral part of the human immune response against viral infections due to their ability to directly target and kill infected cells.

Study shows genetic factors may influence the susceptibility to COVID-19

A new Cleveland Clinic study has identified genetic factors that may influence susceptibility to COVID-19. Published today in BMC Medicine, the study findings could guide personalized treatment for COVID-19.

Viral load peaks in early stages of COVID-19, study shows

In a retrospective study, investigators from New York University Langone Health found that the quantity of SARS-CoV-2 (viral load) collected from patients in the emergency department is significantly higher in patients with fewer or milder symptoms who did not require hospitalization--the opposite of what might be expected.

Psychological distress may indicate the penetration of COVID-19 virus into the central nervous system

Depressed mood or anxiety exhibited in COVID-19 patients may possibly be a sign the virus affects the central nervous system, according to an international study led by a University of Cincinnati College of Medicine researcher.
