Abstract

GITR (glucocorticoid-induced TNF receptor) is a recently identified member of the TNF receptor superfamily. The receptor is preferentially expressed on CD4+CD25+ regulatory T cells and GITR signals break the suppressive activity of the subset. In this study, we wanted to reveal the in vivo function of GITR in chronic graft-versus-host disease (cGVHD), a lupus-like autoimmune disease. A single injection of anti-GITR monoclonal antibody (DTA-1) was effective in blocking the progression of cGVHD in the parent-into-F1 model. Treatment of DTA-1 significantly decreased levels of IgG1 anti-DNA autoantibody, inhibited glomerulonephritis, and increased survival. The DTA-1-mediated inhibition of autoantibody production correlated with deletion of B cells and could occur independently of CD4+CD25+ regulatory T cells. Our results indicate that anti-GITR monoclonal antibody may be used as a potential immunotherapeutic agent for preventing cGVHD.
