title: Haplotype-specific suppression of experimental allergic encephalomyelitis with anti-IA antibodies.
abstract: Treatment with monoclonal antibodies directed against the IA antigens of the MHC is known to alter the course and prevent a number of experimental autoimmune diseases. To determine whether the treatment in vivo with anti-IA antibodies is haplotype-specific, we studied the development of EAE in F1 (SJL/J X BALB/c) mice following anti-IA antibody therapy. We report that treatment of animals with monoclonal antibody directed against the high responder allele product, I-As, was successful in preventing disease when therapy was begun either at the time of immunization with antigen, or following passive transfer of MBP-sensitized T cells. Therapy with antibody directed to the low responder allele product (I-Ad), while effective when used at the time of immunization with antigen, was ineffective following passive transfer of MBP-sensitized lymphocytes.
