Multiple sclerosis is an autoimmune disease caused by the body's attack on its own myelin, the substance surrounding and protecting the nerve cells. A viral cause of the disease has been previously studied and reported. Identical twin studies have indicated that the cause may lie beyond genetics,

with less than a third of twin siblings acquiring the disease when the other twin has been diagnosed.The dual virus theory, reported in Nature Science Updates, proposes that the disease occurs when a virus that has proteins resembling myelin initially attacks the body, followed by an infection by a nonmyelin-resembling agent. The initial infection programs CD4+ immune cells to recognize myelin as a foreign tissue, while the second infection stimulates the production of interleukin-12, stimulating the primed CD4+ killer cells, which then attack the myelin, causing the disease known as multiple sclerosis. A number of viruses can stimulate nterleukin-12, including the viruses that cause respiratory infections.The University of Utah Salt Lake City research team infected mice who were susceptible to the disease with a genetically engineered virus containing myelin-like surface proteins, and observed no damage to the

nerve cells as would occur in MS. The mice were later infected with a cowpox virus with no similarity to myelin proteins, and they rapidly developed MS symptoms. Research team member Robert Fujinami summarized, "No one virus has been ascribed as a cause for MS One virus silently primes for autoimmune disease that is then triggered by later viral infections." Researchers hope to identify the viruses involved in the disease so that antiviral therapies or a preventive vaccine can be developed.Learn more from those who have beaten MS, read testimonials: http:///messages/MS-testimonialsTo UNSUBSCRIBE, send blank message to: mscured- List Archives: mscured/messagesWeb Siteshttp://www.ms-diet.org/http://ourworld.cs.com/cah819http://www.ms-selfhelp.orghttp://CureZone.com/diseases/ms/http://www.naturalms.comhttp://CureZone.com/dental/http://www.btinternet.com/~mscentre.oxfordhttp://www.sensiblehealth.com/http://WaterCure2.comSuccess Stories:http://www.curezone.com/Dangerously_Healthy/http://www.wendys-ms-site.com/http://home.san.rr.com/iamshouse/http://www.megahits.com/healthy/page2.htmhttp://www.direct-ms.org/roger.htmlhttp://www.direct-ms.org/roger2.htmlHave a nice day !
