Encephalitogenic regions for the Lewis rat within the myelin basic protein.

The sequence, phe lys asn ile val thr pro arg thr pro pro pro ser gln gly lys gly arg gly leu ser ser arg phe ser trp gly ala glu gly gln isolated from the peptic digestion of guinea pig myelin basicprotein is able to produce EAE in Lewis rats. The synthetic peptide phe lys phe gly gly arg asp ser arg, an analog of residues 154-162, is encephalitogenic in Lewis rats when B. pertussis is used as the adjuvant.
