The cerebrospinal fluid in subacute sclerosing panencephalitis and multiple sclerosis

The intrathecal immune response in multiple sclerosis: a different concept of 'specificity'

A hypothesis is presented in which the immune response in multiple sclerosis is conceived as a primary response to an auto-antigen located within the immune system (e.g. a certain allotype or HLA epitope) which shows subsequent or simultaneous specificity for a greater number of nominal antigens [corrected]. The increased tendency of [corrected] such antibodies to self-aggregation might play a critical role in the pathogenesis.

Cerebrospinal fluid in multiple sclerosis: relationships between immunoglobulins, leucocytes and clinical features

Cerebrospinal fluid (CSF) from 120 patients with multiple sclerosis was analyzed by polyacrylamide gel electrophoresis, as well as routine laboratory microscopy and assays of total protein and immunoglobulin G (IgG). Negative correlations were found between leucocyte counts and patient age, duration of disease and time from last clinical relapse. There was a positive correlation between the leucocyte count and amount of gammaglobulin. A correlation between gammaglobulin content and degree of disability was found. With increasing duration, the gammaglobulin concentration rose only if there was increasing disability. In terms of correlations with clinical features, differences existed depending on whether IgG was assayed immunologically or by electrophoresis and densitometry. Evidence of increased blood: CSF barrier permeability (transudation of high molecular weight proteins) was found in patients with progressive disease. The presence of oligoclonal bands was the CSF abnormality most frequently encountered.
