Zika virus could be used to treat brain cancer

Recent outbreaks of Zika virus have revealed that the virus causes brain defects in unborn children. But researchers from Washington University School of Medicine in St. Louis and the University of California, San Diego report that the virus could eventually be used to target and kill cancer cells in the brain.

Diagnosing Zika

Commercial blood test proves reliable

The Society for Virology (GfV) which promotes virology through the increase and exchange of research within German speaking countries, as well as via cooperation with other scientific societies, announced this year that a new test can unambiguously confirm the diagnosis of a Zika virus infection – leading to fast diagnosis and identification of an infection.

Close contact not at fault for Zika spread

Saliva is no way to pass a Zika virus infection. According to researchers at the University of Wisconsin–Madison who conducted studies with monkeys, casual contact like kissing or sharing a fork or spoon is not enough for the virus to move between hosts.

Zika-vaccine receives boost

A promising Zika vaccine is on its way. Themis Bioscience GmbH (Vienna, Austria), a company specialised in vaccine development, has announced that the firm will receive One milion pounds sterling in funding by the innovation agency of the United Kingdom, Innovate UK, for the further development of this prophylactic vaccine and the conducting of a Phase 1 clinical trial.

Blood test alternative

Oral "Hep E" test could simplify detection tremendously

A saliva test developed by researchers at the Johns Hopkins Bloomberg School of Public Health nearly matches the performance of a blood test widely used to assess recent or past hepatitis E virus infections, a new study reports. The findings could offer an easier, less expensive alternative to gathering data for studying and eventually treating the disease, which infects an estimated 20 million…

Researchers create ‘Rosetta Stone’ to decode immune recognition

Scientists from St. Jude Children’s Research Hospital and Fred Hutchinson Cancer Research Center have developed an algorithm that functions like a Rosetta Stone to help decipher how the immune system recognizes and binds antigens. The research should aid development of more personalized cancer immunotherapy and advance diagnosis and treatment of infectious diseases.

An unusual 'friend' to help fight ovarian cancer

In some cases, the Lassa virus starts with a fever and general weakness, moving toward headache, muscle pain, possible facial swelling, deafness, and worse. About 15 percent of patients hospitalized with severe cases die. Lassa fever is contagious, endemic in West Africa, and Dr. Anthony van den Pol thinks he can use it to cure ovarian cancer.

Virologists are today’s universal necessities

Globalisation has been a defining term in this 21st century: with almost anybody able to visit any place at any time, diseases, viruses and bacteria can be travel companions. Thus virology is gaining increased attention. Professor Barbara Gärtner, President of the German Association of Virology, talks about the issues and challenges arising from this development.

White Blood Cells Control Virus Replication

Certain white blood cells play an important role in bringing a harmful virus under control after kidney transplantations. The results of a research group at the Department of Biomedicine at the University of Basel and University Hospital Basel could contribute to improving control of immunosuppression, avoiding transplant rejection and developing relevant vaccines.

Malaria Treatment

Soon to be Simpler, More Flexible, and More Efficient?

Malaria infections may soon be treated much more efficiently than they are at present. Researchers at the Universities of Bayreuth and Jerusalem have developed a novel drug release procedure for this purpose. The procedure enables the active ingredient Artemisone to be administered reliably at quantities and time intervals that are tailored exactly to the patients’ individual needs. The…

Viruses Overheard Talking to One Another

Viruses may be stealthy invaders, but a study at the Weizmann Institute of Science reveals a new, chatty side of some: for the first time, viruses have been found communicating with one another. This communication – short “posts” left for kin and descendants – helps the viruses reading them to decide how to proceed with the process of infection. The research was reported in Nature.

Evidence of Zika virus found in tears

Researchers have found that Zika virus can live in eyes and have identified genetic material from the virus in tears, according to a study from Washington University School of Medicine in St. Louis. The research, in mice, helps explain why some Zika patients develop eye disease, including a condition known as uveitis that can lead to permanent vision loss.

Researchers Find Herpes Strain in the Nervous System

There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring back and cause complications not typically associated…

Antibodies identified that thwart Zika virus

Scientists at Washington University School of Medicine in St. Louis have identified antibodies capable of protecting against Zika virus infection, a significant step toward developing a vaccine, better diagnostic tests and possibly new antibody-based therapies. The work, in mice, helps clarify recent research that also identified protective Zika antibodies but lacked important details on how the…

Zika: 1.6 million childbearing women are at risk

Research by scientists in the US and UK has estimated that up to 1.65 million childbearing women in Central and South America could become infected by the Zika virus by the end of the first wave of the epidemic. Researchers from the WorldPop Project and Flowminder Foundation at the University of Southampton and colleagues from the University of Notre Dame and University of Oxford have also found…
