Multiple Sclerosis afflicts more than 2.5 million people worldwide. MS is an autoimmune disease that affects the central nervous system, and more particularly, the myelin material that surrounds and protects individual nerve fibers. The body's own immune system attacks the myelin, leaving behind lesions and scarring that interrupt electric impulses traveling to and from the brain. No cure exists for MS, but various treatments are available to improve the quality of life for those living with the disease.


Mark D. Mannie, PhD, of the Department of Microbiology and Immunology at the Brody School of Medicine at East Carolina University, recently developed a unique fusion protein that, when tested in the widely accepted experimental autoimmune encephalomyelitis (EAE) rat and mouse model, produced dramatic tolerogenic effects. Rats and mice whether pretreated or treated following exposure to the EAE stimulating agent, exhibited decreased incidence, reduced symptoms, and delayed onset of attack.

Inventor Profile

Dr. Mark Mannie is a professor in the Department of Microbiology and Immunology at East Carolina University. His primary research interest is to advance a novel class of tolerogenic vaccines as a therapy for mutiple sclerosis. These vaccines consist of cytokine-neuroantigen (NAg) fusion proteins that act to restore homeostatic self-tolerance in EAE. Click to learn more...
