Active Induction of Experimental Autoimmune Encephalomyelitis in C57BL/6 Mice

: The protocol in this chapter presents a method to actively induce experimental autoimmune encephalomyelitis (EAE), one of the most widely used animal models to study efficacy of potential drugs for treatment of multiple sclerosis. Multiple sclerosis is an inflammatory, demyelinating disease of the central nervous system and the most common cause of chronic neurological impairment in young people. In this model EAE is induced in female C57BL/6 mice by immunization with an emulsion of myelin oligodendrocyte glycoprotein (fragment 35-55) in complete Freund's adjuvant, followed by administration of pertussis toxin in phosphate-buffered saline. EAE is evidenced by ascending flaccid paralysis with inflammation targeting the spinal cord.
