Multiple Sclerosis (MS) is known as a chronic demyelinating pathology of the central nervous system. The most accepted MS pathogenesis theory assigns the main role to demyelination of myelin-proteolipid shells due to inflammationrelated with autoimmune reactions. One of the features of MS patients is the enhanced synthesis of oligoclonal IgGs in the bone marrow Cerebrospinal Fluid (CSF). By antigen-specific immunoblotting after isoelectrofocusing of IgGs, oligoclonal IgGs in CSF of MS patients were revealed only against the components of Epstein-Barr virus and Chlamydia. However, there was still unknown to which human auto-antigens in MS patients oligoclonal IgGs may be produced. Here it was first shown that in the CSF of a narrow percentage of MS patients, oligoclonal IgGs are produced against their own antigens: DNA (24% patients), histones (20%), and myelin basic protein (12%). At the same time, the CSF of MS patients contains a very large amount of auto-IgGs-abzymes that hydrolyze DNA, histones, and myelin basic protein, which during isofocusing, are distributed throughout the gel from pH 3 to 10. It is concluded that these multiple IgGs-abzymes, which are dangerous to humans since stimulate development of MS, in the main are non-oligoclonal antibodies.

It was recently shown that IgGs from sera of multiple sclerosis (MS) patients are active in the hydrolysis of DNA and myelin basic protein (MBP). We first analyzed the relative concentration of antibodies against five histones (H1, H2a, H2b, H3, and H4) in the cerebrospinal fluid (CSF) and serum of patients with MS. The relative concentrations of blood and CSF IgGs against histones and their activity in the hydrolysis of five histones varied greatly from patient to patient. However, all 28 IgG preparations were hydrolyzed from one to five histones. Relative activities and correlation coefficients among the activities of IgGs from serum and CSF in the hydrolysis of five histones (H1, H2a, H2b, H3, and H4), DNA, and MBP were calculated. It was shown that auto-IgGs from CSF and sera of MS patients are extremely heterogeneous in their affinity to histones, MBP, and DNA. The heterogeneity of IgG-abzymes hydrolyzing DNA, MBP, and histones from CSF and sera was also demonstrated using their isoelectrofocusing. The isofocusing profiles DNase, MBP-, and histone-hydrolyzing activities of IgGs may be very different for various individuals, but the total IgG subfractions with all their activities are distributed from pH 3 to 10.
