Affinity of antigen-specific IgG distinguishes multiple sclerosis from encephalitis

Both groups of patients showed antigen-specific oligoclonal bands locally synthesised in the CSF. When the affinity distribution of the antigen-specific IgG was measured...

Zusammenfassung:The characteristics of antigen-specific IgG in patients with multiple sclerosis and patients with encephalitis have been compared. Both groups of patients showed antigen-specific oligoclonal bands locally synthesised in the CSF. When the affinity distribution of the antigen-specific IgG was measured there was a marked difference between the two groups. Encephalitis patients had high affinity antibody against the causative antigen. This was consistent with the antibody undergoing affinity maturation as a result of the immune system fighting a primary infection. Multiple sclerosis patients lacked high affinity response. This lack of high affinity antibody was also seen in those encephalitis patients when antigens other than the causative antigen were studied.
