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.
A new type of CRISPR platform that leverages the benefits of a compact RNA-editing protein could result in enhanced diagnostic tests for COVID-19.
A recent study has identified differences in immune pathway activation to influenza infection between people of European and African genetic ancestry.
Global provider of human and animal biospecimens - AMSBIO offers a custom procurement service enabling researchers to source specific biofluid and tissue samples which are not already available in their extensive biorepository.
A plant-based antiviral treatment for Covid-19, recently discovered by scientists at the University of Nottingham, has been found to be just as effective at treating all variants of the virus SARS-CoV-2, even the highly infectious Delta variant.
With around 256 million cases and more than 5 million deaths worldwide, the COVID-19 pandemic has challenged scientists and those in the medical field. Researchers are working to find effective vaccines and therapies, as well as understand the long-term effects of the infection.
Recent research reveals how genetic variations associated with severe cases of COVID-19 impact the immune cells.
Scientists from the University of Colorado Anschutz Medical Campus recently identified how an RNA molecule from a virus develops a complex, three-dimensional structure, and is capable of changing its shape to hijack host proteins.
While dendritic cell immunoreceptor (DCIR) is known to mediate inflammation and bone metabolism, ligands that bind DCIR and the mechanisms underlying DCIR activity remain poorly understood.
A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes — immune system cells also known as helper T cells — produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at significantly higher levels than for those who are unvaccinated.
When the pro-inflammatory pair, a receptor called CCR2 and its ligand CCL-2, get together, it increases the risk of developing type 1 diabetes, scientists report.
Scientists from the Wistar Institute revealed how major features on the surface of HIV-infected cells help the disease avoid detection by the immune system.
INTEGRA’s VOYAGER adjustable tip spacing pipette is supporting crucial experimental work in longitudinal HIV studies.
In light of frequent false positives, a team of Canadian researchers has shown that rapid antigen tests for SARS-CoV-2 work only when manufacturer instructions are followed.
A new viral tomato disease that broke in the past few years has threatened tomato production across the globe.
A group of researchers recently discovered a compound that reveals potential in alleviating the symptoms of coronavirus infections.
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.
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.
Around 3%–10% of the individuals infected by the SARS-CoV-2 experience moderate to severe disease.
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.
RNAs are best known as the molecules that translate information encoded in genes into proteins with their myriad of activities.
