title: A molecular Trojan horse: hijacking the bone marrow to treat autoimmune diseases.
abstract: Autoimmune diseases such as multiple sclerosis, type 1 diabetes, systemic sclerosis, and rheumatoid arthritis affect approximately 5% of the population and are characterized by a destructive immune response directed to self-tissues. Treatments are often designed to dampen the immune system and are therefore associated with unwanted side effects. A major challenge is to find a cure that does not compromise normal immune function. From our understanding of how the immune system develops, it is clear that mechanisms designed to eliminate or maintain control over self-reactive clones are critical for normal health. These key concepts form the crux of many experimental strategies currently aimed at abrogating the autoimmune response. In this review, we focus on the strategy of harnessing the bone marrow compartment through genetic manipulation directed at promoting ectopic autoantigen expression. Our experience with this strategy is presented in the context of reports in the literature and we argue for the potential benefit of translating this approach to the treatment of human autoimmune disease.
