Abstract

Rheumatoid arthritis (RA) is an autoimmune disease that causes painful inflammation of the synovium of the patient’s joints. However, current treatments for RA have a variety of drawbacks. They often are ineffective, expensive, invasive, risky, cause an immune response, and/ or only provide short term relief. Thus, we developed a new treatment for preventing inflammation: TNF-receptors anchored onto exosome surfaces. Exosomes are nanovesicles that are naturally secreted by most of the cells in our bodies. The many benefits of using exosomes include non-immunogenicity, natural stability in the body, and non-invasiveness. We have demonstrated that exosome membrane bound TNF-receptors have the ability to prevent inflammation in mammalian cells. The success of this project could lead to a clinically effective treatment of rheumatoid arthritis as well as other inflammatory diseases by opening the doors to further research and development of exosomal therapies.
