Injections of zika virus destroys brain tumors
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.

Molecular diagnostic test for Covid-19, Flu, RSV receives CE mark
A new rapid molecular diagnostic test from Cepheid has received the CE mark for distribution in the European market. The test, called Xpert Xpress CoV-2/Flu/RSV plus, is designed for qualitative detection of the viruses causing Covid-19, Flu A, Flu B, and respiratory syncytial virus (RSV) infections from a single patient sample. The new plus version of the test provides a third gene target for…

Viruses leave traces long after the infection is over
Viruses do not always kill the cells they infect. Researchers at the University of Basel have discovered in experiments with mice that cells have the power to self-heal and eliminate viruses. However, these cells undergo long-term changes. The findings may provide a hint as to why cured hepatitis C patients are more susceptible to liver cancer for years after.

'Nano traps' to lock up and neutralize viruses
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell…

Prediciting viral infections with microscopy & deep learning
When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluoresence images from live cells, researchers at the University of Zurich have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage.

Long Covid symptoms likely caused by Epstein-Barr virus reactivation
Epstein-Barr virus (EBV) reactivation resulting from the inflammatory response to coronavirus infection may be the cause of previously unexplained long Covid symptoms—such as fatigue, brain fog, and rashes—that occur in approximately 30% of patients after recovery from initial Covid-19 infection. The first evidence linking EBV reactivation to long Covid, as well as an analysis of long Covid…

Mild COVID-19 induces lasting antibody protection
Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all the while.

How retroviruses become infectious
Understanding every step in the life cycle of a virus is crucial for identifying potential targets for treatment. Now, scientists at the Institute of Science and Technology (IST) Austria were able to show how a virus from the retrovirus family – the same family as HIV – protects its genetic information and becomes infectious. Furthermore, they show an unexpected flexibility of the virus. This…

Worm infestation in the gut can lower viral defenses
Infection with parasitic intestinal worms (helminths) can apparently cause sexually transmitted viral in-fections to be much more severe elsewhere in the body. This is shown by a study led by the Universities of Cape Town and Bonn. According to the study, helminth-infected mice developed significantly more severe symptoms after infection with a genital herpes viruses (Herpes Simplex Virus). The…
