In order to explore the T‐cell repertoire to myelin basic protein (BP) of both multiple sclerosis (MS) patients and healthy subjects (HS), we raised BP reactive T‐cell lines from blood mononuclear cells of eight MS patients and five HS. Thes lines were trigered in vitro by human BP. When analyzing their patterns of recognition of human BP versus heterologous BP, we could observe differences between healthy subjects and MS patients. Whereas T‐cell lines from healthy subjects developed a response to heterologous BP, which was in most cases equal or higher than that elicited by human BP, T‐cell lines from most MS patients displayed a low response, or no response at all, to one or several of the heterologous BP tested. A low response to bovine BP was only observed in active cases, whereas decreased responses to rat and/or monkey BP were observed both during remission and during active disease. This may indicate that T‐cell repertoire to BP in MS patients differs from that of healthy subjects. BP‐reactive T‐cell clones were obtained by limiting dilution from two healthy subject lines. Their pattern of response to heterologous BP as compared to human BP suggest that T‐cell from the same individual can recognize different BP epitopes.
