[Immunomorphologic features of experimental allergic encephalomyelitis induced by the administration of tryptophan peptide].Biull Eksp Biol Med. 1989 Aug; 108(8):241-4.BE
Three patterns of EAE with different morbidity and mortality rates were induced in the guinea pigs inoculated with various doses of tryptophane peptide (TP) and complete Freund's adjuvant. TP-sensitized animals manifested the delayed type hypersensitivity (DTH) reactions to TP and circulating anti-TP and -BPF antibodies were not found, polypeptide fraction of myelin basic protein (BPF while a A correlation was revealed between the DTH-reactions and EAE development. Intracutaneous TP and BPF injections at the early period before the EAE onset resulted in reduction of morbidity rate from 90 to 50 per cent. For the first time with the help of modified Marchi method demyelination has been shown to be highly marked in CNS tissue process in CNS can be caused by cell-mediated immune of animals given TP. It is supposed that the demyelinating reaction to encephalitogenic fragment of BP molecule. The data indicate a possibility of EAE inhibition by means of TP and BPF injections in saline solution.
