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.

Cytokine storms in COVID-19 patients may prevent the development of long-term immunity

Shiv Pillai, MD, Ph.D., investigator in the Ragon Institute of MGH, MIT and Harvard and professor at Harvard Medical School (HMS), recently published a paper in Cell showing that that high levels of some cytokines seen in COVID-19 patients, as part of a cytokine storm, may prevent the development of long-term immunity to SARS-CoV-2, the virus that causes COVID-19.

Study shows how herpesvirus invades human cells and causes chickenpox

Inspite of several years of research, scientists are still clueless about how herpesviruses penetrate the human cells.

Study shows age is a major risk factor for dying from COVID-19 infection

According to a study, genes that play a significant role in enabling SARS-CoV-2 to penetrate the heart cells become more active as people age.

Surface structure of SARS-CoV-2 virus offers insights for development of therapeutics

At the start of a COVID-19 infection, the coronavirus SARS-CoV-2 docks onto human cells using the spike-like proteins on its surface. The spike protein is at the centre of vaccine development because it triggers an immune response in humans.

LJI scientists tracked down rare stem cells that generate neutrophils in humans

Neutrophils are the warriors of the immune system. They are always ready to spring to action to help heal injuries or fight off disease. Unless, that is, something goes wrong in their developmental process.

Study investigates how Ebola virus adapts to bat and human cells

A new study by researchers from The University of Texas Medical Branch at Galveston uncovered new information on why the Ebola virus can live within bats without causing them harm, while the same virus wreaks deadly havoc to people.

Novel gene editing approach removes latent herpes simplex virus 1

Infectious disease researchers at Fred Hutchinson Cancer Research Center have used a gene editing approach to remove latent herpes simplex virus 1, or HSV-1, also known as oral herpes.

Influenza viruses can spread through the air on dust, fibers

Influenza viruses can spread through the air on dust, fibers and other microscopic particles, according to new research from the University of California, Davis and the Icahn School of Medicine at Mt. Sinai.

Researchers detect robust T cell response in patients with mild COVID-19 infection

Mild cases of COVID-19 pandemic can activate strong responses from memory T cells, even when detectable virus-specific antibody responses are absent.

Study shows how proteins act as a defense mechanism to protect their own DNA

Viruses usually inject their DNA into a host cell to multiply. As soon as this foreign material penetrates the intracellular fluid, it activates a defense mechanism called the cGAS-STING pathway.

Study shows how viruses escape the immune system

Scientists from the University of Otago have gained a deeper understanding of how viruses work and escape the immune system. The team is presently using this finding to find out more about the COVID-19 pandemic.

High-speed AFM enables real-time visualization of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

Novel receptor protein can be a promising treatment for COVID-19

A novel receptor protein that binds to the SARS-CoV-2 virus and prevents it from entering cells may hold promise for treating COVID-19 and other coronavirus-related diseases, according to research published online Aug. 4 in the journal SCIENCE.

Antibodies from natural controllers appear to play crucial role in eliminating hepatitis B virus

Infections in humans caused by the hepatitis B virus (HBV) represent a major public health problem. Despite the availability of effective protective vaccines, more than 250 million individuals worldwide are chronically infected according to WHO estimates.

Researchers use supercomputer to gain new insights into hepatitis B virus

Researchers at the University of Delaware, using supercomputing resources and collaborating with scientists at Indiana University, have gained new understanding of the virus that causes hepatitis B and the "spiky ball" that encloses the virus's genetic blueprint.

Study identifies a protein that facilitates spread of SARS-CoV-2 virus through cells

Eric Ross and Sean Cascarina, biochemistry and molecular biology researchers at Colorado State University, have released a research paper identifying a protein encoded by SARS-CoV-2, the virus that causes COVID-19, that may be associated with the quick spread of the virus through cells in the human body.

Study shows MARCH8 protein protects against infection through antiviral mechanisms

A protein known as MARCH8 protects humans from infection by tagging the vesicular stomatitis virus for destruction, while simply holding the HIV hostage.

COVID-19 Prevention Network announces two trials to evaluate monoclonal antibodies

The COVID-19 Prevention Network (CoVPN) today announced two Phase 3 trials to determine whether monoclonal antibodies (mAbs) can prevent SARS-CoV-2, the virus that causes COVID-19.

Adapting the equipment and expertise of agtech labs could help combat pandemics

Just as redeploying a fleet of small British fishing boats helped during the Battle of Dunkirk, marshalling the research equipment and expertise of the many agtech labs around the world could help combat pandemics, say the authors of a just-published article in Nature Biotechnology.
