Abstract [en]

The B cell response to central nervous system (CNS) myelin and myelin basic protein, as well as total numbers of IgG secreting cells, was studied in acute experimental allergic encephalomyelitis using a nitrocellulose immunospot assay. The method was able to detect single plasma cells secreting antibodies. Cells secreting antibodies against myelin antigens were detected in regional lymph node cell suspension by day 5 post-immunization (p.i.). At that time no anti-myelin antibodies were detected free in serum. Later, at day 15 p.i., specific antibody secreting cells were found in bone marrow and spleen indicating a generalization of the immune response. The B cell response became partly sequestered to the target of immune attack since an increased number of IgG secreting cells was detected among mononuclear cells recovered from the CNS. Studies of cellular secretion of antibodies rather than free levels in body fluids may be a more accurate reflection of the in vivo B cell response. These findings may be generally considered in studies of B cell mediated immunity in neuroinflammatory diseases.
