Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs

01.02.2006


A "starry sky" map linking the myriad interactions between the influenza virus and its human host will help guide researchers in creating new anti-viral drugs, say researchers at UT Southwestern Medical Center.



The on-line map, part of a project called Reactome, is intended to teach scientists about parts of the influenza lifecycle they might not be familiar with, and to help researchers look at specific reactions and figure out ways to block them.

"Understanding how influenza reacts with its host is really critical for the rational design of anti-viral drugs and new vaccines," said Dr. Richard Scheuermann, professor of pathology at UT Southwestern.


Reactome, online at www.reactome.com, was created in 2004 and includes a variety of biochemical pathways for processes such as cell death in several species, primarily human.

Individual reactions are shown as separate items, which are linked by arrows to associated reactions. The diagrams resemble constellations; hence the "starry sky" nickname.

The influenza pathway component and a simultaneous HIV database going online mark the first time Reactome has displayed interactions between an infectious pathogen and its host, Dr. Scheuermann said.

Pathogens such as influenza have evolved to use hosts to promote their growth, while at the same time blocking the host reactions that recognize and respond to infection. Each year, for example, winter is marked by the outbreak of flu caused by new viruses that the human immune system doesn’t recognize.

The new Reactome influenza database outlines a typical virus life cycle, which will be updated as more research becomes available.

"In the future, the goal is to build out all of the host-pathogen reactions," Dr. Scheuermann said.

UT Southwestern’s participation was part of the BioHealthBase Bioinformatics Resource Center project, a collaboration between Dr. Scheuermann’s lab and a bioinformatics software engineering team at Northrop Grumman Information Technology funded by the National Institute of Allergy and Infectious Diseases.

Reactome is an NIH-funded collaboration between Dr. Lincoln Stein’s laboratory at Cold Spring Harbor Laboratory in New York and the laboratory of Dr. Ewan Birney of the European Bioinformatics Institute, part of the European Molecular Biology Laboratory, in Hinxton, UK.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
