Abstract

Transgenic mice expressing DQA1(*)0301 and DQB1(*)0302 (HLA-DQ8) molecules in class II-deficient Ab°mice are susceptible to collagen-induced arthritis (CIA). To evaluate the role of the H2-E molecule (a homolog of HLA-DR) in DQ-restricted arthritis, the H2-E gene was introduced into DQ8.Ab°mice to generate DQ8/E+.Ab°mice. Expression of the E molecule protects DQ8.Ab°mice against arthritis. In vitro studies using draining lymph nodes from mice primed with bovine type II collagen (BII) showed that the response to BII in both transgenics is DQ and CD4 restricted. Challenge with BII in vitro leads to production of high levels of IFN-γ in DQ8 and IL-4 in DQ8/E+ mice. We have hypothesized that the H2-E molecule modulates the T cell repertoire and changes the cytokine balance, resulting in protection of disease.
