Suppression and reversal of allergic encephalomyelitis in guinea pigs with a non-encephalitogenic analogue of the tryptophan region of the myelin basic protein.
J Immunol. 1976 Jan; 116(1):126-30.JI

Abstract

The administration of synthetic peptide S42 leads to suppression and reversal of experimental allergic encephalomyelitis (EAE) induced in guinea pigs by myelin basic protein. Peptide S42 contains a linear sequence of 21 amino acid residues, H-Phe-Ser-Trp-Gln-Lys-Phe-Ser-Trp-Gln-Lys-Phe-Ser-Trp-Gln-Lys-Phe-Ser-Trp-Gln-Lys-Gly-OH, made up of four repeating unit sequences of H-Phe-Ser-Trp-Gln-Lys-OH in addition to a C-terminal glycine. Injected at relatively high doses, peptide S42 is non-encephalitogenic. It induces delayed-type hypersensitivity which is not followed by EAE, and elicits delayed-type hypersensitivity responses in peptide S42, encephalitogenic trytophan peptide, or BP-challenged animals for either of the three antigens. The repeating unit sequence of peptide S42 is analogous to the encephalitogenic tryptophan region of the BP molecules . The sequence homology is responsible for cellular recognition of this antigen by the skin test assay and suggests in vivo interaction between peptide S42 and EAE-inducing cells leading to suppression and reversal of disease.
