title: Modulation of experimental autoimmune uveoretinitis by adoptive transfer of cells from rats immunized with anti-S-antigen monoclonal antibody.
abstract: Preimmunization of rnu/+ rats with the mouse monoclonal antibody S2D2 against retinal S-antigen (S-Ag) leads to an anti-idiotypic (anti-Id) response and to protection against experimental autoimmune uveoretinitis (EAU) provoked by a subsequent challenge with S-Ag in complete Freund's adjuvant (CFA). Suppression of EAU can be passively transferred using lymph node and/or spleen cells from donors with active anti-Id immunity to naive rnu/+ recipients, prior to immunization with bovine S-Ag in CFA. In contrast, passive administration of IgG from S2D2-immunized rats did not produce suppression. High levels of anti-Id S2D2 antibodies were found: (1) in rats presenting an inhibited EAU after sensitization with S2D2 or after passive transfer of anti-S2D2 cells prior to the S-Ag immunization; and (2) in rats with a severe EAU after transfer of anti-S2D2 IgG associated with anti-S2D2 cells prior to the S-Ag challenge. No effect on the anti-S-Ag antibody level could be detected. These experiments suggest that EAU, a mostly T cell-dependent disease, can be down regulated by anti-Id lymphoid cells.
