Novel RNA-based therapy for treatment of autoimmune diseases

Loss of immunological self-tolerance followed by attack of self-reactive T cells to target organs plays a major role in the formation of autoimmune diseases such as multiple sclerosis (MS). In a very recent study published in Science, our researchers (in collaboration with Johannes Gutenberg University Medical Center and BioNTech) employed a non-inflammatory RNA vaccine that targets self-antigens to antigen presenting cells without inducing co-stimulation. This therapy was able to modulate self-reactive T cells, induce regulatory T cells and re-establish self-tolerance leading to suppression of the disease in various mouse models of MS. The results of this study may help the development of potent therapies against complex autoimmune diseases.
