Previous studies have shown that differential susceptibility to actively induced experimental allergic encephalomyelitis (EAE) and experimental allergic orchitis (EAO) exists among various BALB/c substrains. Of eight substrains studied for EAE and 13 for EAO, BALB/cJ mice are phenotypically the most resistant to disease induction. Resistance to both diseases is controlled by single recessive mutations unlinked to any of the known alleles distinguishing BALB/cJ mice. In this study, segregation analysis employing a second generation backcross population shows that resistance to both EAE and EAO is due to a mutation in a common immunoregulatory gene. The role of immunoregulatory cells in controlling EAE resistance was examined using adoptive transfer protocols. BALB/cJ mice immunized with spinal cord homogenate plus adjuvants generate immunoregulatory spleen cells (SpC) that, when transferred to naive BALB/cByJ recipients, reduce the incidence and severity of EAE. Treatment of such cells with either cytotoxic monoclonal anti-Thy1.2 or anti-CD4 plus C' before transfer abrogates the ability of BALB/cJ SpC to inhibit disease. In contrast, neither SpC from adjuvant-immunized BALB/cJ nor spinal cord homogenate- plus adjuvant-primed BALB/cByJ donors influences the incidence or severity of disease observed in recipients. In addition, the role of environment in influencing susceptibility to EAE and EAO in BALB/c mice is documented. Taken together, these results support the existence of a common disease susceptibility locus in the pathways leading to two autoantigenically distinct CD4+ T cell-mediated, organ-specific, autoimmune diseases.
