“As glucosamine is able to effectively suppress acute EAE, has
low or absent toxicity, and has been safely used in humans orally, our study suggests a potential use for this drug alone or in
combination with other disease-modifying immunotherapies to enhance their efficacy and reduce their doses in MS and possibly other autoimmune disorders. Furthermore, because glucosamine functions not simply as an immunosuppressant, but as a mild immunomodulator, administration of glucosamine provides a novel immunoregulatory approach for autoimmune disorders.
