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.

Monoclonal antibodies mitigate inflammatory consequences of SARS-CoV-2 exposure in macaques

Monoclonal antibodies protected aged, diabetic rhesus macaque monkeys from disease due to SARS-CoV-2 and reduced signs of inflammation, including in cerebrospinal fluid, according to a new study from researchers at the University of California, Davis.

SARS-CoV-2 virus may be able to infect the inner ear, study shows

Many Covid-19 patients have reported symptoms affecting the ears, including hearing loss and tinnitus. Dizziness and balance problems can also occur, suggesting that the SARS-CoV-2 virus may be able to infect the inner ear.

Study unravels unknown facts about SARS-CoV-2 infection

Around 3%–10% of the individuals infected by the SARS-CoV-2 experience moderate to severe disease.

Researchers develop new approach to selectively turn on gene therapies in target cells

Researchers at MIT and Harvard University have designed a way to selectively turn on gene therapies in target cells, including human cells. Their technology can detect specific messenger RNA sequences in cells, and that detection then triggers production of a specific protein from a transgene, or artificial gene.

New eToeholds could make RNA therapeutics more safer and effective

RNAs are best known as the molecules that translate information encoded in genes into proteins with their myriad of activities.

Novel genetic biomarkers accurately predict SARS-CoV-2 infection, says study

Researchers from the University of Colorado School of Medicine identified specific genetic biomarkers that reveal who is infected with COVID-19.

Correction of immune system's faulty timing may offer a new strategy to prevent severe COVID-19

Once an infection is under control, the body normally uses a biochemical messenger known as TGFβ to downgrade its immune response.

Horse hyperimmune antibody may be an efficient approach to combat SARS-CoV-2

A study conducted by a consortium of Brazilian researchers has demonstrated that a hyperimmune serum consisting of purified antibody fragments produced in horses may be an efficient approach to combat covid-19.

Junk DNA' plays a crucial role in early embryonic development in all mammals, study shows

Nearly half of our DNA has been written off as junk, the discards of evolution: sidelined or broken genes, viruses that got stuck in our genome and were dismembered or silenced, none of it relevant to the human organism or human evolution.

Scientists reveal the importance of circadian rhythm on the immune system

Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms.

Metabolic restoration could provide natural protection against HIV

The human immunodeficiency virus (HIV-1) particularly attacks CD4 lymphocytes, a type of white blood cell considered to be the conductor of the immune system.

Study identifies highly potent monoclonal antibody against all SARS-CoV-2 variants

Researchers identified a greatly potent monoclonal antibody that aims at the spike protein of SARS-CoV-2.

Pioneering gene therapy has long-lasting effects on children with deadly immune disorder

Over a decade ago, UCLA physician-scientists began using a pioneering gene therapy they developed to treat children born with a rare and deadly immune system disorder. They now report that the effects of the therapy appear to be long-lasting, with 90% of patients who received the treatment eight to 11 years ago still disease-free.
