Scientists are said to have made a major breakthrough as they have found the chemical that enhances the symptoms of multiple sclerosis.

The chemical known as granulocyte-macrophage colony-stimulating factor is an immune system which is part of the body's defense against the disease.

According to two studies done by scientists from the University of Zurich and those from Thomas Jefferson University in Philadelphia, eliminating excess GM-CSF could help counter the deteriorating effects of MS and further relapses.

Professor Becher, of the University of Zurich, stated though it was easy to stop MS in mice, they waited until they were sick and had the disease, which can be likened to the most common form of MS.

The drugs which erased GM-CSF from their systems prevented relapses and improved their health.

However, trails on humans will commence during the end of this year, also it's said to take about seven years before the drugs hit the market.

The scientists intend to use the drugs against GM-CST to treat other diseases such as rheumatoid, arthritis and diabetes.

Dr. Doug Brown, of the MS Society, expressed that more work needs to be done as they need to understand the disease in humans, though they are contented with the trails and aspire to produce positive results.
