Monoclonal antibody effective against norovirus

25.07.2013
Researchers from the National Institute of Allergy and Infectious Diseases (NIAID) provide the first proof of concept data showing that a monoclonal antibody can neutralize human norovirus.

This research, which could one day lead to effective therapies against the virus, was published online ahead of print in the Journal of Virology.

"We initiated this work because there is presently no virus-specific treatment or vaccine to control the norovirus illness," says Kim Y. Green, a researcher on the study. "Our working hypothesis was that a highly specific norovirus antibody that binds to the outer surface of the virus particle might prevent the ability of the virus to infect susceptible host cells."

The team first isolated genes from chimpanzee immune cells encoding norovirus-specific antibodies. They then converted these into human-compatible full-length immunoglobulin molecules. They successfully tested two of the antibodies against norovirus infection in chimpanzees.

"An effective therapeutic antibody might be explored as both a treatment for norovirus gastroenteritis, and as a disease prevention strategy," says Green. "Consider a developing outbreak scenario in which food-handlers, healthcare workers, deployed military, or travelers could reduce risk of infection, incapacitation, and spread if a safe and inexpensive treatment is immediately available."

Norovirus causes roughly 20 million cases of acute diarrhea and vomiting annually in the US, alone, according to the US Centers for Disease Control and Prevention (CDC). While in most people, symptoms last a day or two, for those with impaired immune systems, and the young and the aged, norovirus can be life-threatening. It is responsible for an estimated 70,000 hospitalizations and 800 deaths annually, and roughly one in 15 Americans get the disease every year. It is unusually contagious, via the fecal-oral route. People who have had norovirus remain highly contagious for at least three days after symptoms abate.

A copy of the manuscript can be found online at http://bit.ly/asmtip0713b. The paper is scheduled to be formally published in the September 2013 Journal of Virology.

Journal of Virology is a publication of the American Society for Microbiology (ASM). The ASM is the largest single life science society, composed of over 39,000 scientists and health professionals. Its mission is to advance the microbiological sciences as a vehicle for understanding life processes and to apply and communicate this knowledge for the improvement of health and environmental and economic well-being worldwide.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
