Men hold secret to protect women from multiple sclerosis

Men are much less likely to get multiple sclerosis (MS) than women, and one reason is that they are protected by high levels of testosterone. Scientists have now discovered how it works. They have identified a guardian molecule — triggered by testosterone — that appears to protect males from disease. When female mice with disease are treated with this protective molecule, their symptoms were eliminated. The findings could lead to a new therapy for MS.Original Article
