摘要：We have produced hybridoma antibodies directed against immunoglobulins present in the cerebrospinal fluid of a patient with multiple sclerosis (MS). One hybridoma antibody recognized an idiotypic determinant of an immunoglobulin population [an idiotype (Id)] which constituted approximately 1% of the immunoglobulin present in the cerebrospinal fluid. The Id focused in the pH range 8.0-8.4. It was present at roughly 10- to 15-fold higher relative (compared to total immunoglobulin) concentration in cerebrospinal fluid than in serum of the homologous MS patient. The Id could not be detected in three cerebrospinal fluid samples and 28 serum samples of heterologous MS patients or in the serum of 43 optic neuritis patients. The Id persisted in the homologous MS patient at increased concentration over the entire (6 years) observation period. The Id could be shown to react with a Theiler murine encephalomyelitis virus strain WW which was isolated from mice after inoculation with periplaque white matter from brain in a histologically confirmed case of MS.
