520 |a Mucosal administration of low doses of myelin basic protein (MBP) peptide 68-86 (MBP 68-86) or anti-inflammatory cytokine IL-10 effectively prevented experimental allergic encephalomyelitis (EAE), but failed to suppress the disease if given after 7 days postimmunization (p.i.), i.e., after T cell priming had occurred. We anticipated that combined administration of autoantigen and IL-10 can treat incipient EAE. Lewis rats with EAE actively induced with MBP 68-86 and complete Freund's adjuvant received 120 microg MBP 68-86 + 200 ng IL-10 per rat per day from day 7 p.i. and for 5 consecutive days. These rats showed later onset, lower clinical scores, less body weight loss, and shorter duration of EAE than rats receiving MBP 68-86 or IL-10 only or PBS. EAE amelioration was associated with decreased infiltration of ED1(+) macrophages and CD4(+) T cells within the central nervous system and with decreased proliferative responses of lymph node cells, indicating that combined administration of MBP 68-86 and IL-10 induced immune hyporesponsiveness. IFN-gamma secretion as well as IFN-gamma, TNF-alpha, IL-4, and IL-10 mRNA expression by lymph node MNC was down-regulated in the treated rats. Immune hyporesponsiveness, rather than immune deviation or regulatory mechanisms, seems to be responsible for the protection of EAE after autoantigen + IL-10 administration by the nasal route
