Scientists from France and Belgium gained insights into the structure and function of a central liver protein: NTCP, a cellular-entry pathway for bile salts – but also for certain hepatitis viruses.
SARS-CoV-2 depends on the broadly antiviral interferon-induced human transmembrane proteins , to enter human cells and replicate inside them.
Two years after infection with COVID-19, half of patients who were admitted to hospitals still have at least one symptom, according to the longest follow-up study to date.
Researchers developed a new microfluidic chip with broad applications for detecting viruses, pathogens, bacteria and other biomarkers in liquid samples.
Dormant herpesviruses induce their reactivation via a previously unknown cellular mechanism mediated by a viral microRNA, Würzburg researchers discovered.
UV radiation is one of the go-to methods for preventing the spread of SARS-CoV-2. But what UV dosage kills the virus? What wavelength? How long? A new study answers many of those questions.
In 2020 and 2021, the death toll associated with Covid-19 was approximately 14.9 million, according to the World Health Organization. However, the global distribution has been far from equal.
Cognitive impairment as a result of severe Covid-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, scientists found.
Six in ten people with Covid-19 still have at least one symptom a year later, a new study has found. Furthermore, symptoms that don’t clear up after 15 weeks are likely to last at least a year.
Using mass spectrometry and chromatography techniques, UK researchers have developed an approach to predict infection severity among Covid-19 patients, as well as potential outcomes.
A global analysis of nearly 6 million Covid-19 deaths finds an increase in mortality at weekends compared to weekdays. Bureaucratic and reporting delays alone do not explain this, researchers report.
By comparing the infectious viral load caused by ancestral SARS-CoV-2 as well as by the Delta and Omicron variants, scientists highlight the benefits of vaccination.
A platform for studying how the human immune system responds to hepatitis C infection by combining microfluidic technology with liver organoids could speed the hunt for a vaccine.
COVID-19 measures such as school closures and ‘high-traffic and mixing’ areas had the strongest association, providing clues for new intervention approaches.
The tool has made it possible to detect SARS-CoV-2 in exudate from symptomatic patients with a sensitivity of 100% and a specificity of 87.5%
Scientists have confirmed that an inhaled form of COVID vaccine can provide broad, long-lasting protection against the original strain of SARS-CoV-2 and variants of concern.
Researchers have developed an inexpensive, non-toxic coating for almost any fabric that decreases the infectivity of the virus that causes COVID-19 by up to 90 per cent.
Scientists have investigated the effectiveness of various common hand disinfectants against hepatitis E. They were able to show that most formulations do not completely inactivate the virus.
Researchers have developed a device that removes one of the biggest bottlenecks preventing quick, reliable malaria diagnosis.
A connection between the Epstein-Barr virus and multiple sclerosis has long been suspected. A new study provides ‘compelling evidence of causality’.
In both the mice and organoids, cytokines suppressed tumor growth after treatment, and defense cells migrated to the brain region affected by the tumor, alerting the immune system to its existence.
Researchers have developed a diagnostic for SARS-CoV-2 that is capable of differentiating between COVID-19 and the garden-variety bug with fast turnaround.
Scientists at have designed a quantum sensor to detect SARS-CoV-2 faster, cheaper, and more accurate than the current gold-standard technique, PCR.
An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants.
In experiments using saliva samples from COVID-19 patients, the gum, which contains the ACE2 protein, neutralized the virus.
