Researchers have identified two types of white blood cells that are thought to cause multiple sclerosis by attacking nerve tissue. The finding is considered a crucial step toward treating the disease.

In a study published in the current issue of Proceedings of the National Academy of Sciences, the research team reported that they isolated the white blood cells, or lymphocytes, that appear to attack myelin, a protein that covers and protects nerve cells. The loss of myelin is the key event in the progression of multiple sclerosis.
