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 identifies potent neutralizing antibodies against SARS-CoV-2

A joint research team led by Sunney Xie, Director of Beijing Advanced Innovation Center for Genomics at Peking University has successfully identified multiple highly potent neutralizing antibodies against the novel coronavirus SARS-CoV-2, the causative virus of the respiratory disease COVID-19, from convalescent plasma by high-throughput single-cell sequencing.

GlobalData highlights a downturn in worldwide meat market due to COVID-19 pandemic

The activity of meat manufacturers across North America continues to generate a lot of noise, with some processing plants from major companies such as Tyson and JBS resuming operations. Continued turbulence among meat packing players is likely to damage consumers’ trust in associated food products, says GlobalData, a leading data and analytics company.

Study shows how ocean virus captures the metabolism of carbon-storing bacteria

Below the surface of the ocean, a virus is stealing the metabolism of the most abundant organism present on Earth. That might be attractive to those who breathe above the ocean’s surface.

X-ray experiments reveal antibody to block entry of SARS-CoV-2

As scientists across the globe race to develop a vaccine against SARS-CoV-2, the coronavirus that causes COVID-19, an international team led by Davide Corti at Vir Biotechnology and David Veesler at the University of Washington has been working around the clock on a complementary approach - identifying neutralizing antibodies that could be used as a preventative treatment or as a post-exposure therapy.

Study shows coronavirus does not induce cross-protective immune antibodies

According to researchers, patients infected with severe acute respiratory syndrome coronavirus (SARS-CoV) or SARS-CoV-2 generate antibodies that adhere to the other coronavirus; however, the cross-reactive antibodies are not actually cross-protective, as far as cell-culture experiments are concerned.

Smokers More Likely To Express ACE2 Protein That SARS-COV-2 Uses

Researchers report that smoking increases the gene expression of ACE2, the protein that binds SARS-CoV-2, which may promote COVID-19 infection.

Study offers a benchmark for testing potential vaccines for COVID-19

Globally, researchers are racing against time to design a vaccine to guard against the COVID-19 infection, and epidemiologists are taking efforts to predict the way the coronavirus pandemic will spread until the availability of such a vaccine.

Computational methods can help design protein-based vaccines

Vaccines are regarded as an effective intervention to stop the spread of infectious diseases. They produce antibodies by activating the immune system.

Coronavirus attacking microRNA numbers reduce with age

A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.

New type of antigen-presenting immune cell discovered

With a discovery that could rewrite the immunology textbooks, an international group of scientists, including the teams of Bart Lambrecht, Martin Guilliams, Hamida Hammad, and Charlotte Scott (all from the VIB-UGent Center for Inflammation Research) identified a new type of antigen-presenting immune cell.
