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.

Researchers discover how long-term memory T cells are formed after Covid-19

Exposure to SARS-CoV-2 by infection or vaccination generates immune cells that provide long-term immunity. These long-lived memory T cells play a key role in preventing severe cases of Covid-19. Researchers at the University of Zurich have now discovered how these memory T cells form.

Omicron variant inefficient in causing diseases than other COVID-19 variants, study reveals

Scientists from the Department of Microbiology at the University of Hong Kong (HK) have found that the Omicron variant of SARS-CoV-2 replicates less efficiently and causes fewer diseases than other variants of COVID19.

COVID-19 vaccines prompt the body to make long-lasting T cells against different variants

Scientists at La Jolla Institute for Immunology (LJI) have found that four COVID-19 vaccines (Pfizer-BioNTech, Moderna, J&J/Janssen, and Novavax) prompt the body to make effective, long-lasting T cells against SARS-CoV-2.

Researchers use cryo-EM to rapidly characterize antibodies at atomic level

Scripps Research scientists have found a mechanism that may be able to bypass one of the critical steps in current vaccine production.

Study provides insight into replication and transcription machinery of ranaviruses

Nucleo-cytoplasmic large DNA viruses (NCLDVs) of the genus Ranavirus (family iridoviridae) have been isolated from aquatic species such as reptiles, amphibians, and bony fish. Poikilotherms are at risk from these promiscuous infections.

Memory T cells formed after prior infection or vaccination respond to omicron variant

The omicron variant can partly evade the antibody response provided by vaccination or infection with previous variants of SARS-CoV-2.

Study identifies respiratory syncytial viral protein that mediates RSV-induced autophagy

A viral protein might contain information that could be used to avoid pneumonia due to the body’s overactive response to respiratory viruses, such as COVID-19.

Non-neutralizing antibodies likely to protect against COVID, says study

Non-neutralizing antibodies may also be crucial in giving protection against COVID-19, according to a recent study from Lund University in Sweden.

Researchers discover a key mechanism used by Zika virus to evade cell’s antiviral response

The world knows SARS-CoV-2 intimately now, but there are more than 200 virus species capable of infecting humans and causing disease.

Researchers discover a gene variant that protects against severe COVID-19 infection

An international metastudy led by researchers at Karolinska Institute in Sweden has identified a specific gene variant that protects against severe COVID-19 infection.

Researchers identify new potential drug target that may block SARS-CoV-2 infection

In the quest for new treatments for COVID-19, a team led by researchers at UC San Francisco has identified a new potential drug target that may block infection by SARS-CoV-2. The protein, called BRD2, regulates the ACE2 receptor, which the novel coronavirus relies on to gain entry to its host's cells.

Synthetic antibody demonstrates Omicron detection along with all other variants of concern

MIP Diagnostics Ltd. has today announced that its synthetic SARS-CoV-2 antibody (COVID-19 nanoMIPTM) can detect the Omicron variant as well as previously proven Alpha, Beta, Delta and Gamma variants of the COVID-19 virus.
