Sweet discovery offers protection against killer viruses

Washington, Nov 4 (ANI): A new research suggests that a purified form of a product modified from simple sugar molecules can eradicate killer viruses by mobilizing white blood cells.

When a team of European researchers sought to discover how a class of antiviral drugs worked, they looked in an unlikely place: the sugar dish.

The new suggests that a purified and modified form of a simple sugar chain may stop fast-acting and deadly viruses, such as Ebola, Lassa, or Marburg viruses, in their tracks.

This compound, called chlorite-oxidized oxyamylose or COAM, could be a very attractive therapeutic option because not only did this compound enhance the early-stage immune defenses in mice, but because of sugar’s abundance, it is derived from easily obtainable sources.

“We modified and purified a safe drug from natural sources and discovered how it can protect against deadly virus infections,” said Ghislain Opdenakker, M.D., a researcher involved in the study from the Laboratory of Immunobiology at the Rega Institute for Medical Research and the University of Leuven in Belgium.

To make this discovery, researchers infected mice with a virus that kills in less than a week. When one group of these infected mice was treated with an unpurified version of the compound, about half of the infected mice were protected from the effects of the virus.

Researchers then purified the compound and treated another group of infected mice. In that group, more than 90 percent survived the deadly infection.

These results suggest that the purified compound almost completely blocked the killer virus by speeding the response of the body’s fast-acting immune cells, called white blood cells or leukocytes, at the early stage of infection.

The study appears in the Journal of Leukocyte Biology. (ANI)
