title: The compartmental IgM and IgA response within the central nervous system.
abstract: The diagnostic value of the locally synthesized IgA and IgM fractions in cerebrospinal fluid is described. The differentiation of the CSF immunoglobulins was performed with the help of a diagram that had been established on empirical grounds. Immunoglobulin G generally dominates the humoral immune response within the central nervous system, but in some diseases a comparatively strong participation of the other immunoglobulins was found: IgA in purulent meningitis and neurotuberculosis, IgM in tick-borne early summer meningoencephalitis. In meningopolyneuritis Bannwarth and mumps meningoencephalitis a broad three class response was found. The diagnostic significance of these findings is independent of the disease stage, since the compartmental immune response lacks the Nossal-Switch from IgM- to IgG- antibodies.
