Prof. Michel Revel, MD, PhD

Director, Co-Founder

Prof. Revel is Professor Emeritus of Molecular Genetics at the Weizmann Institute of Science. His research on Interferon, its mechanisms of action and the isolation of the human Interferon-beta gene, have led to the development of Interferon-beta therapy for the treatment of multiple sclerosis, Rebif®, Blockbuster drug marketed worldwide.

In recent years, Prof. Revel's laboratory focused on hESC and succeeded to produce nerve myelinating cells that, when transplanted in myelin-deficient animals, have regenerated the myelin coating.
