Abstract

Peptide p259-271 of the human acetylcholine receptor α-subunit, preferentially stimulates T cells of patients with myasthenia gravis (MG) and is an immunodominant epitope for T cells of BALB/c mice. A p259-271 specific T cell line of BALB/c origin was established and was shown to induce experimental MG in naive mice. Seven analogs of p259-271 were synthesized, and two of them were found to inhibit the p259-271 specific proliferative responses of the line and of p259-271 primed lymph node cells. Moreover, the most efficient inhibitor, analog 262Lys, prevented the MG related manifestations in mice inoculated with the line, and might be of potential value for the treatment of MG.
