Most emerging infectious diseases affecting people are zoonotic — they make the jump from other animals to humans. Transmission, however, is a two-way street. These zoonotic diseases can also jump from humans to other animals. Even if a disease is eradicated in humans, it can live on in animals that act as reservoirs, ensuring that […]Continue Reading ...
NASA has come up with a warning about herpes zoster or shingles being activated among crew aboard the Space Shuttle and the International Space Station missions. The problem was highlighted in a study that appeared in the latest issue of the journal Frontiers in Microbiology. Varicella zoster virus or varicella-zoster virus (VZV) is one of […]Continue Reading ...
Scientists have shown that different segments of a virus genome can exist in distinct cells but work together to cause an infection. The findings, published in the open-access journal eLife, upturn a fundamental model in virology that a virus genome enters and replicates within a single cell and then moves on to replicate in another. […]Continue Reading ...
A team of researchers from Scripps Research and Janssen Research & Development LLC has discovered an orally active small molecule that neutralizes influenza A group 1 viruses, the most common flu strains. Scientists uncovered the potential therapy in a large chemical library and optimized lead compounds to produce JNJ-4796. Now they have proven its effectiveness […]Continue Reading ...
Researchers at Duke-NUS Medical School and their colleagues have identified a surprising interaction between dengue and Zika viruses that sheds lights on the significant fetal brain abnormalities linked to Zika virus. The researchers found that fetal mouse brain damage was much worse if the mothers infected with Zika also had dengue antibodies. They further determined […]Continue Reading ...
Researchers have developed a new method for the creation of custom-made proteins that can bypass the protective coating of the HIV virus, allowing antibodies to neutralize the Env gene, which enables the virus to bind and enter human immune cells.

New evidence suggests that Chikungunya virus arrived in Brazil at least one year earlier than it was detected by public health surveillance systems. Scientists at the Center for Infection and Immunity (CII) at the Columbia Mailman School of Public Health and Fundação Oswaldo Cruz published their findings in the journal Scientific Reports. Blood samples collected […]Continue Reading ...
CRCHUM researchers are exploring a potential therapeutic approach Researchers at the University of Montreal Hospital Research Centre (CRCHUM) have shown that immunotherapy treatments against cancer could reduce the amount of virus that persists in people on triple therapy. In a study published in the journal Nature Communications, they show, in the cells of people living […]Continue Reading ...
As far as research is concerned, hepatitis E (HEV) had long led a shadowy existence – even though it is the main cause for acute viral inflammation of the liver. It causes an estimated 70,000 deaths annually. Professor Eike Steinmann and Dr. Daniel Todt from the Department for Molecular and Medical Virology at Ruhr-Universität Bochum […]Continue Reading ...
Dr Paulo Rocha from the University of Bath’s Department of Electronic & Electrical Engineering is developing a low-cost integrative sensing tool for early detection of Dengue virus, using a novel platform containing electrical sensors to investigate the behavior of human cells infected with Dengue virus. When someone is infected by the Dengue virus it produces […]Continue Reading ...
Reviewed by Matt Pullen, B.Sc.Mar 11 2019 Pilar Domingo, Ernesto Segredo, María Durán and Rafael Sanjuán, from the Institute of Integrated Systems Biology (I²SysBio), a mixed center of the University of Valencia and the Spanish National Research Council (CSIC), have shown that viruses behave altruistically to avoid the immune system. This research, published on Monday […]Continue Reading ...
The circulation of the dengue virus for the past sixty years in South-East Asia is relatively well known. For Zika, the situation is much less clear. In an attempt to shed light on Zika circulation, scientists from the Institut Pasteur and the CNRS, in collaboration with US teams and the Thai National Institute of Health, […]Continue Reading ...
A new way to create proteins that can sneak through HIV’s protective coating may be a step toward understanding the key components needed for developing a vaccine for the virus, according to researchers. Using computational modeling, a team of researchers led by Penn State designed and created proteins that mimicked different surface features of HIV. […]Continue Reading ...
Researchers at Cardiff University have used x-ray crystallography and computer simulation to get a closer look at how viruses bind cells and cause infection. The new insight could help in the development of drugs and therapies for infections and further advance the exploitation of viruses for medical treatments. The first author of the study, Alex […]Continue Reading ...
A research team from Tübingen and Göttingen has described in the renowned journal Cell Reports a new mechanism how the Ebola virus escapes the immune system. The virus causes infected cells to release decoys that inactivate neutralizing antibodies and prevent immune cells from releasing important messenger molecules. These findings could lead to the development of […]Continue Reading ...
