- AB Immunization of a limited number of rodent strains with central nervous
- system-derived Ags induces experimental allergic encephalomyelitis
- (EAE). In contrast to susceptible female SJL mice, age-matched males are
- resistant to actively induced EAE. The ability of immunization with
- neuroAg to induce Ag-specific T cell activation in resistant male mice
- was examined. Ag-specific T cell proliferation was found following
- immunization of both male and female SJL mice. Draining lymph node
- cytokine mRNA patterns demonstrated that immunization of EAE-resistant
- male mice resulted in a Th2-type pattern. By contrast, immunization of
- EAE-susceptible female mice resulted in a Th1-type pattern. Priming of
- Th1- and Th2-type responses was confirmed by analysis of cytokines
- secreted following Ag-specific proliferation. In contrast to the
- transfer of myelin basic protein (MBP)-specific Th1-type T cells derived
- from female mice, which induced acute and relapse EAE, transfer of
- MBP-specific Th2-type T cells derived from male mice resulted in no
- clinical or histologic evidence of EAE. A mixture of MBP-specific Th1
- and Th2 type cells was transferred to naive recipients to determine if
- the neuroAg-specific Th2-type cells exerted a regulatory influence on
- EAE. Acute disease was partially eliminated and relapses were completely
- eliminated in these recipients. Analysis of spinal cords showed the
- presence of both Th1 and Th2 cytokine mRNAs. These data are consistent
- with both the ability of Th2-type cells to suppress autoimmunity and a
- homeostatic mechanism of T cell regulation based on the cross-regulation
- of Th1 and Th2 cells in the maintenance of peripheral tolerance.
