Interferon-beta is a remarkably pleiotropic molecule. Antiviral, pro- and antiproliferative, pro- and antiapoptotic, and complex immunoregulatory activities have all been described. The precise mechanism(s) that underlie the beneficial effects of interferon-beta in multiple sclerosis remain poorly understood; this has hindered progress in the search for more effective therapies. An increasing body of literature supports the hypothesis that interferon-beta-mediated changes in the production and activities of the immunoregulatory cytokines interleukin-12 and interleukin-10 are important to the therapeutic benefits of interferon-beta in multiple sclerosis. These data are reviewed here.
