New findings could improve STI vaccinations
In a new study, researchers from King’s College London have shown how skin vaccination can generate protective CD8 T-cells that are recruited to the genital tissues and could be used as a vaccination strategy for sexually transmitted infections (STIs), such as HIV or herpes simplex virus.

Trapping viruses inside a cell: harmful or helpful?
Viruses are often used as vehicles for delivery in gene therapy because they’re engineered not to damage the cell once they get there, but neglecting to consider how the virus will exit the cell could have consequences. Some viruses use a molecule called heparan sulfate to help them attach to cells. The molecule, found in many different kinds of cells (including those from animal tissue), could…

Enterovirus infections: The disease is rare and research scant
Neurological complications due to infections with (novel) enteroviruses are rarely the focus of medical research. Thus, an article published in the German medical journal Der Nervenarzt (published at the Medizinische Hochschule Hanover (MHH) – has created quite a stir. We spoke with one of the authors, Professor Martin Stangel, about current clinical practice in terms of enterovirus.…

Seeing the unseeable life inside a virus
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 Baker from Cardiff University’s School of…

Asian mosquitos go West – and tropical diseases come along
Rising temperatures due to global warming are creating a permanent habitat in Europe for mosquitos from Asia. The Asian tiger mosquito (Aedes albopictus), or Aedes japonicas, are important vectors for the transmission of pathogens previously only found in tropical regions, like dengue fever, West Nile fever and the Chikungunya virus.

Why the flu is especially dangerous for kidney failure patients
In patients with kidney failure, influenza-like illness (ILI) likely contributes to more than 1,000 deaths per year. The finding, which comes from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN), points to the importance of protection against, surveillance of, and, where possible, treatment of such infections in patients with kidney dysfunction.…

Heat it and read it
You’re sweating and feverish and have no idea why. Fortunately, Sandia National Laboratories scientists have built a device that can pinpoint what’s wrong in less than an hour. Unlike most medical diagnostic devices which can perform only one type of test — either protein or nucleic acid tests — Sandia’s SpinDx can now perform both. This allows it to identify nearly any cause of…

Researchers discover Ebola-related virus carried by bats
Researchers from Singapore’s Duke-NUS Medical School, in collaboration with scientists in China, have identified and characterised a new genus of filovirus from a Rousettus bat in China. Their findings were published in the journal Nature Microbiology. Bat-borne viruses around the world pose a threat to human and animal health. Filoviruses, especially Ebola virus and Marburg virus, are…

Pathway Ebola virus uses to enter cells pinpointed
The new outbreak of the deadly Ebola virus declared just last week in eastern Democratic Republic of Congo is believed to have claimed more than 30 victims so far, highlighting the continued urgency to find a way to stop the pathogen from killing the people it infects. A new study is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to…

‘Why not take a risk?’ belief boosts antibiotic overuse
Antibiotics are mostly prescribed for acute respiratory infections (ARIs), yet most of these infections are viral. A new study shows that inappropriate antibiotics prescriptions are widespread, contributing dangerously helping antibiotic-resistant organisms to grow. Overuse could be due to attitudes among patients and clinicians, current George Washington University research suggests.

Defense against viruses or autoimmune disorder?
The first defense line of the body against virus infections is composed of so-called restriction factors. SAMHD1, one of such restriction factors, does not only play a role in the defense against viruses but also in the development of autoimmune disorders and cancer. The question of which effect SAMHD1 exertsin the cell is decided by addition or removal of phosphate groups.

Could a new pig virus be a potential threat to humans?
A recently identified pig virus can readily find its way into laboratory-cultured cells of people and other species, a discovery that raises concerns about the potential for outbreaks that threaten human and animal health.

Little-known bacteria might grind Zika and dengue infections to a halt
A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. Wolbachia are bacteria that occur widely in insects and, once they do, inhibit certain pathogenic viruses the insects carry. The problem with using Wolbachia broadly to protect humans is that the bacteria do not normally occur in mosquitoes…

Cats could help in development of anti-HIV drugs
Feline AIDS is caused by the Feline Immunodeficiency Virus (FIV), which is very similar to the HIV-1 virus that affects millions of humans. While FIV does not infect humans, many groups research the virus to benefit cats, and perhaps more importantly, because of its many parallels with the AIDS virus. Despite the use of dedicated drugs, HIV-1 manages to thrive and multiply within the cell and…
