Oligoclonal Immunoglobutins, Light Chain Ratios and Free Light Chains in Cerebrospinal Fluid and Serum from Patients Affected with Various Neurological Diseases

Several immunological parameters, of which the most important are the kappa-lambda ratios, the presence of free light chains and the double ring formation for kappa-chains in single radial immunodiffusion, were investigated in the cerebrospinal fluid and serum of patients affected with different neurological diseases. Parallels were run either with multiple sclerosis or subacute sclerosing panencephalitis. There seems to be a correlation between the frequency of the presence of free light chains and the degree of severity of the immunological process.
