The oral administration of myelin basic protein (MBP) to Lewis rats prior to an encephalitogenic challenge resulted in total inhibition or a significant delay in the onset of experimental autoimmune encephalomyelitis (EAE). In vitro lymphocyte proliferative responses to MBP were significantly decreased in MBP-fed rats when compared with vehicle-fed controls. Suppression of EAE and in vitro proliferative responses to MBP were observed to be antigen specific, since oral feeding of a control protein exerted no suppressive effect. Moreover, the specificity of MBP-induced oral tolerance was shown to be species specific, since feeding guinea pig MBP (GPMBP) or human MBP (HuMBP) induced protection only against a GPMBP or HuMBP challenge, respectively. Conversely, Lewis rats could not be orally tolerized to the self antigen rat MBP.
