  One of the world’s largest multiple sclerosis centers


Narrator:    This is Science Today. The Multiple Sclerosis Center at the University of California, San Francisco, is one of the largest MS centers in the world. Dr. Ari Green is the assistant director of the center, which has 12 clinicians and about eight laboratory scientists who are dedicated full-time to understanding the disease.

Green:    We take care of approximately 4,000 to 5,000 patients with multiple sclerosis from across the western United States and really around the world as a referral center. And we have been the center for a number of clinical trials to investigate new therapies for MS, but also what we would like for our group to be is at the cutting edge of both ways of treating the disease as well as ways of tracking and predicting what will happen with the disease.

Narrator:    Green says MS is one of the most challenging diseases to understand because it's at the nexus of two of the most complicated biological systems that exist — the brain and the immune system. For Science Today, I'm Larissa Branin.
