Interferon beta in the treatment of multiple sclerosis: mechanisms of action
1Department of Oncology and Clinical Neurosciences, Faculty of Medicine, University of Calgary, Alberta, Canada.
Abstract:
Interferon beta (IFN-beta) has been shown in several clinical trials to have efficacy in MS. Its mechanism of action, however, remains unclear. In this review, several biological activities of IFN-beta are highlighted, including its inhibitory effects on proliferation of leukocytes and antigen presentation. Furthermore, IFN-beta may modulate the profile of cytokine production toward that of the anti-inflammatory phenotype, and this appears to occur in the systemic circulation and within the CNS. Finally, IFN-beta can reduce T-cell migration by inhibiting the activity of T-cell matrix metalloproteinases. These activities are likely to act in concert to account for the mechanism of IFN-beta in MS.

- To elucidate the potential mechanisms underlying IFN-beta's efficacy in multiple sclerosis (MS).
- To consolidate current knowledge on how IFN-beta modulates the immune response in MS.
Main Methods:
- Literature review of preclinical and clinical studies on Interferon beta (IFN-beta).
- Analysis of biological activities including immune cell proliferation, antigen presentation, and cytokine profiles.
- Examination of IFN-beta's effects on T-cell migration and matrix metalloproteinase activity.
Main Results:
- IFN-beta inhibits leukocyte proliferation and antigen presentation.
- IFN-beta promotes an anti-inflammatory cytokine profile in both systemic circulation and the central nervous system (CNS).
- IFN-beta reduces T-cell migration by inhibiting T-cell matrix metalloproteinases.
