Role of CD5+ B-1 cells in EAE pathogenesis.
Hybridoma cell lines producing natural autoantibodies (NAA), generated from A.SW mice with progressive experimental autoimmune encephalomyelitis (P-EAE), have been shown to cause demyelination and renal pathology when injected into naive mice. To investigate the relative contribution of these antibodies to disease pathogenesis, B-1 cells, the major producers of NAA, were depleted by hypotonic shock. Depletion of B-1 cells during the effector phase of EAE significantly decreased the severity of demyelination and overall pathology in the brain. There was also a decreased incidence of P-EAE and a decrease in clinical score. Depletion during the induction phase of the disease resulted in an increase in the incidence of P-EAE and in the clinical score. Overall, B-1 cells were found to modulate EAE pathogenesis.
