Successful treatment of EAE in rhesus monkeys with MHC class II specific monoclonal antibodies
article
Experimental Allergic Encephalomyelitis (EAE) was induced in rhesus monkeys by subcutaneous immunization with calfbrain homogenate in complete Freunds adjuvant. Monkeys were treated with major histocompatibility complex (MHC) Class II specific monoclonal antibodies (MoAb) as soon as the first clinical EAE signs became apparent. Two different treatments were tested. One consisted of 10 daily injections of a mixture of two MHC Class II specific MoAb, reactive with a monomorphic structure of rhesus monkey Class II molecules. The other consisted of 10 daily injections of Genox3.53, specific for HLA-DQW1. This MoAb crossreacts well with monkeys and also detects a polymorphism in this species and is presumably reactive with the RhLA-DQW1 antigen. Both MoAb treatments could modify the clinical course of EAE favourably. Untreated animals invariably died within 3 d of the onset of clinical EAE signs. Only one of the three monkeys treated with the monomorphic MHC Class II MoAb preparation died within 3 d, and the other two survived significantly longer than untreated animals. Both animals treated with Genox3.53 survived significantly longer than untreated control animals. Although only a few animals were tested, these results clearly show the possible beneficial influence of MHC Class II specific MoAb on a T-cell mediated autoimmune disease. © 1988.
