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.

New study reveals metabolic signature of SARS-CoV-2 infection involving signs of multi-organ damage

SARS-CoV-2 can lead to a broad range of symptoms, from absolutely nothing to multi-organ failure, severe respiratory stress, and eventually death.

Protein inhibitors neutralize SARS-CoV-2 infection in cell culture

Using innovative computer-based approaches, researchers have developed protein inhibitors that block the interaction between the SARS-CoV-2 virus and human cell receptor ACE2.

Researchers review the role of macrophage activation syndrome in COVID-19

A major percentage of COVID-19 cases have become so severe that hospital admissions have become mandatory for both monitoring and treatment.

Computer-designed proteins protect lab-grown human cells from SARS-CoV-2

Computer-designed small proteins have now been shown to protect lab-grown human cells from SARS-CoV-2, the coronavirus that causes COVID-19.

Study shows a new way to capture “live” images of immune cells inside the lungs

A team of researchers from the University of Calgary has identified a new method to capture “live” pictures of immune cells within the lungs.

Researchers develop cellular roadmaps to predict the body’s susceptibility to coronavirus

A new study has created promising roadmaps to predict how the novel coronavirus infects organs and detects the factors that could limit the infection.

Zika virus infection during pregnancy can cause severe abnormalities in the fetus

Zika virus infection during pregnancy can cause severe abnormalities in the fetus, including malformations such as microcephaly. In a small proportion of cases, the disease may lead to miscarriage and perinatal death.

Researchers investigate cellular factors that could be significant for COVID-19 infection

An infection with the coronavirus SARS-CoV-2 can affect multiple organs. With this in mind, researchers of the German Center for Neurodegenerative Diseases (DZNE) and Cornell University in the US have investigated cellular factors that could be significant for an infection.

Study shows cell surface proteins in placental tissue prevent COVID-19 transmission

Scientists from the Maxwell Finland Laboratory for Infectious Diseases at Boston Medical Center have discovered properties in the placental tissue that may play a significant role in inhibiting the transmission of COVID-19 infection from a mother, who has the novel coronavirus, to her fetus.

Researchers develop new gene therapy for congenital blindness

Retinitis pigmentosa is the most prevalent form of congenital blindness. Using a retinitis pigmentosa mouse model, researchers from Ludwig-Maximilians Universitaet (LMU) in Munich have now shown that targeted activation of genes of similar function can compensate for the primary defect.

3 Sep 2020

Combined point-of-care nucleic acid and antibody test can speed up COVID-19 detection

A Cambridge hospital has piloted the use of combined rapid point-of-care nucleic acid and antibody testing for SARS-CoV-2 infection after researchers at the University of Cambridge showed that this approach was superior to virus detection alone for diagnosing COVID-19 disease.

Study reveals a successful strategy to fight influenza

For a long time, influenza scientists have largely focused their studies on the epithelial cells that line the lungs.

2 Sep 2020

Researchers identify an effective treatment for severe cases of COVID-19 infection

Scientists are trying to figure out how SARS-CoV-2 leads to a range of symptoms that appear to persist long after the active viral infection.

Study shows neutralizing antibodies can protect against SARS-CoV-2 virus

In May, a fishing vessel exited a port and returned with the first-ever proof that neutralizing antibodies offer protection from being re-infected by SARS-CoV-2.

Decisions of small-scale poultry farmers can influence the spread of deadly virus

Small-scale poultry farmers in Vietnam tend to respond to viral outbreaks of highly pathogenic avian influenza (HPAI) by rapidly selling their birds as a way to avoid financial loss, according to a new study by an international team of researchers.

Researchers explore the structure and dynamics of biological nanomachine

Cells that are infected by a virus or carry a carcinogenic mutation, for example, produce proteins foreign to the body.

Understanding skin damage caused by rubbing could lead to better topical skin treatments

Understanding the skin damage caused by rubbing could lead to better topical skin treatments and help prevent the formation of new routes for viral and bacterial infection.

New cellular pathway can protect cells from infection by Ebola virus, coronavirus

Discoveries from the Benaroya Research Institute at Virginia Mason (BRI) have identified a new cellular protection pathway that targets a common vulnerability in several different pandemic viruses, and collaborators at Case Western Reserve University, Boston University School of Medicine and MRIGlobal have shown that this pathway can protect cells from infection by Ebola virus and coronaviruses, like SARS-CoV-2.
