Host-targeting drugs offer new way to fight flu resistance

A drug that targets the host rather than the virus could get around the problem of anti-viral resistance. Every year, hundreds of thousands of people die of seasonal influenza, caused by infection with influenza A and B viruses.

Antiviral COVID-19 drug shows no benefit for Long COVID

Results from a clinical trial funded by the National Institutes of Health (NIH) and published today in the journal Lancet Infectious Diseases show that the antiviral drug, PAXLOVID, commonly prescribed to treat acute COVID-19, does not have an impact on Long COVID symptoms when compared to placebo.

Oral drug candidate blocks transmission of measles-like disease in ferrets

A new oral antiviral drug candidate administered either before or after direct contact or airborne exposure to canine distemper virus, which causes measles-like disease in ferrets, blocks transmission of the virus and reduces clinical symptoms, according to a study published in the journal Nature Microbiology by researchers in the Center for Translational Antiviral Research (CTAR) at Georgia State University.

New viral library helps scientists study thousands of proteins

To prevent viruses from sickening or killing us - whether it's an individual case of hepatitis B or a COVID pandemic - it's crucial to understand how the proteins they make initiate changes in our bodies that allow them to flourish.

Scientists discover 70 existing drugs that block deadly hantavirus infections

Researchers screened over 5,000 compounds and successfully pinpointed 70 existing drugs, including unexpected beta-lactam antibiotics, that effectively suppress Puumala orthohantavirus infection in human cells. This milestone drug-repurposing study provides an immediate, fast-tracked pipeline for developing the first approved treatments against life-threatening hantavirus diseases.

New oral antiviral drug candidate targets measles and Croup syndrome

A new oral antiviral drug candidate has been developed for the treatment of diseases caused by orthoparamyxoviruses, such as measles and Croup syndrome, according to a study published by researchers in the Center for Translational Antiviral Research at Georgia State University.

Paxlovid speeds recovery but does not reduce severe COVID outcomes in vaccinated adults

Paxlovid (nirmatrelvir-ritonavir) does not reduce hospital admissions or deaths in vaccinated adults at higher risk of severe COVID-19, despite helping them recover faster, according to results from two national trials published today in the New England Journal of Medicine.

Marburg virus enters human cells far more efficiently than Ebola

In a new study published in Nature, University of Minnesota researchers found that the Marburg virus, one of the world's deadliest pathogens with an average 73% fatality rate, is unusually efficient at getting inside human cells.

Bat viruses in Indochina Peninsula reveal viral diversity, PEDV origins, and spillover risks

Bats, critical reservoirs of viruses with significant cross-species spillover risks, have long been understudied in the Indochina Peninsula.

Study clarifies role of steroids in treating HSV encephalitis

A major UK clinical trial has shown that adding the corticosteroid dexamethasone to standard antiviral treatment for encephalitis (brain inflammation), caused by herpes simplex virus (HSV) does not improve long-term outcomes overall, although early use may lead to better recovery, and the treatment is safe for patients in whom encephalitis is suspected.

Virus shells use asymmetry to control RNA release and infection

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate imbalance in their shape that helps them infect their hosts.

Study reveals how viral social interactions shape resistance to antivirals

Interactions among viruses can help them succeed inside their hosts or impart vulnerabilities that make them easier to treat. Scientists are learning the ways viruses mingle inside the cells they infect, as well as the consequences of their socializing.

Uppsala researchers develop Trojan horse approach for medulloblastoma treatment

The malignant pediatric brain tumor medulloblastoma is driven by proteins deep within the cancer cells, for which there are often no effective drugs available.

Researchers develop a versatile tool for controlling gene activity

Investigators at Weill Cornell Medicine have developed a versatile and non-toxic technology for controlling the activity of any gene in a cell. Such "gene-switch" tools allow scientists to "turn on" or "turn off" a target gene to study how it works, model diseases and design new therapies.
