Reduced production of myelin, a type of protective nerve fiber that is lost in diseases like multiple sclerosis, may also play a role in the development of mental illness. Myelin is an insulating material that wraps around the axon, the threadlike part of a nerve cell through which the cell sends impulses to other nerve cells. Depriving mice of social contact reduced their myelin production. Does this make MS a "lonely" disease?

Researcher Michael Brown tested the effects of a protein that causes inflammation when cells are damaged on the cells that line blood vessels in both African-Americans and Caucasians, to determine whether the inflammation affected the cells differently.

Your immune system, which protects you from disease, likes you to be dirty and happy (or does it)? A new study shows that men who are hostile and prone to frequent intense feelings of anger and depression could be harming their immune systems, making them more vulnerable to health problems like heart disease.

Researcher Steven Boyle studied over 300 male Vietnam veterans who were part of a larger 20-year study on the effects of Agent Orange. For the study, besides physical tests, the vets underwent a standard psychological test used to assess hostility, depression and anger.
