Researchers on the trail of a treatment for cancer of the immune system

Danish researchers from the University of Copenhagen have become the first in the world to regulate a special receptor or bio-antenna that plays a vital part when the Epstein Barr herpes virus infects people and when this infection appears to be mutating into cancer of the immune system. Using a biochemical blueprint and a tiny bio-molecule the Danish researchers have succeeded in blocking the receptor concerned. This will make it possible to adjust and regulate the memory cells of the immune system. The discovery has just been published in the Journal of Biological Chemistry.

Infection with Epstein Barr means that the B cells, which are the primary memory cells of the immune system, are hi-jacked. When the virus has penetrated, researchers observe an excess of a special bio-antenna, a receptor known as EB12, suddenly sprouting from the surface of the B cells. But why they do so remains a mystery.

The receptors are a vital component of the way cells communicate with their surroundings via hormones and other bio-molecules, for example, but in a body consisting of millions of cells and transmitters it can be hard to determine the part each molecule plays.
