A. A Breakthrough In Multiple Sclerosis Research

Narrator: This is Science Today. Researchers have discovered the body's own antibodies play a major role in the development of multiple sclerosis. Previously the immune system's killer T-cells were thought to be the main culprit. But Dr. Claude Genain, a neurology professor at the University of California, San Francisco, literally caught antibodies in the act of destroying the myelin sheath, which protects vital nerve fibers of the spinal cord and brain.

Genain: That has never been shown before in human MS The implications of this are by combining the previous therapies that are efficient against T cells and some therapies that are efficient against antibodies, we will most likely end up with a much more efficient treatment for the disease.

Narrator: Genain hopes to develop molecules that mimic antibodies that bind to myelin.

Genain: But do not have their detrimental effect on the myelin sheath and we are hoping that these molecules will be able to compete with antibodies to prevent the antibodies to create the damage.
