| abstractText | H2 and HLA transgenes were utilized to clarify the role of class II genes in susceptibility to experimental autoimmune thyroiditis (EAT), a model for Hashimoto's thyroiditis (HT). Susceptibility was transferred by H2 class II transgenes to a resistant haplotype and by HLA-DRA/DRB1*0301 (DR3) transgene into class II-negative Ab0 mice. Mice with a HLA-DRB1*1502 (DR2) transgene remain resistant to mouse thyroglobulin (mTg)-induced EAT, illustrating the role of HLA-DRB1 polymorphism. A role for HLA-DQ polymorphism was shown with hTg-induced EAT in HLA-DQ*0301/DQB1*0302 (DQ8), but not HLA-DQ*0103/DQB1*0601 (DQ6), transgenic mice. Yet, both DQ8+ and DQ6+ mice were unresponsive to mTg. Single transgenes obviate the problems from DR/DQ linkage disequilibrium and may distinguish the degree of susceptibility and the response to shared or specific epitopes. The introduction of conserved Eak transgene into Ab0 mice reveals a new role for H2E molecules in EAT. Without H2A molecules, EalphaEbetab molecules and T cells respond to hTg or pTg with severe thyroiditis, but not to mTg, thus distinguishing self from nonself. However, IAb genes in resistant mice ameliorate Eak transgene-mediated thyroiditis, similar to the effect of Eak transgene on IAs-mediated EAT. Studies in HLA DQ/DR double transgenic mice simulating human haplotypes could reveal HLA class II gene interactions in HT. |
