There is a clear need for more effective, safe and at the same time orally available treatment options. Here we review the potential of fumaric acid esters (FAE) as a new therapeutic option for MS. FAE have been claimed to possess immunomodulatory properties and are already in clinical use as second-line therapy for severe systemic psoriasis. They also displayed beneficial effects in experimental autoimmune encephalomyelitis (EAE), a model mimicking many aspects of MS. In addition, FAE may also act on the blood-brain barrier and exert neuroprotective properties via activation of anti-oxidative pathways. A first magnetic resonance imaging (MRI) based Phase II study in relapsing-remitting MS (RRMS) revealed a dose-dependent, significant reduction of brain lesion activity for BG-12, a dimethyl FAE compound. Currently, two multicentre, Phase III studies for testing clinical efficacy in RRMS are initiated. In view of their profile, FAE compounds may have the potential to add to our therapeutic options in RRMS in the future.</p>","PeriodicalId":86075,"journal":{"name":"International MS journal","volume":"15 1","pages":"12-8"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"27605246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been a renewed interest in the potential roles of both antibody-dependent and antibody-independent B-cell responses in multiple sclerosis (MS) and its animal model. Accumulating data suggest that the contribution of B-cells and their secreted products to central nervous system (CNS) inflammatory diseases may relate to the abilities of B-cells to (1) differentiate into plasmocytes that produce antibodies, (2) function as antigen-presenting cells, contributing to Tcell activation, (3) produce effector cytokines that may modulate the local immune environment, (4) harbour the Epstein Barr virus in a chronically activated state, and (5) play a role in formation and maintenance of new lymphoid foci within the CNS. Understanding the biological and clinical impact of selective B-cell interventions such as rituximab (Rituxan, Genentech Inc., San Francisco, CA, USA) becomes of particular interest. This review will present the rational for B-cell based therapies in MS and related diseases and preliminary data suggesting a therapeutic benefit in MS and related diseases.

This review describes the various events observed in these primordial MS lesions in recent studies using immunocytochemistry, magnetic resonance spectroscopy and gene-activation analysis. Despite the various controversial mechanisms proposed to explain the findings, all seem to require the presence of an as-yet undiscovered primary provoking antigen, which is most probably being processed internally by immune systems of the central nervous system.
