Abstract

γδ T cells have been shown to have immunoregulatory functions in several experimental autoimmune models. A mutation of the Foxp3 gene leads to the absence of regulatory T cells (Tregs) and a fatal systemic autoimmune disease in scurfy mice. Transfer of scurfy lymphocytes to RAG deficient (RAG(-/-)) recipients reproduces the inflammatory phenotype of the scurfy donor, including hepatitis and pneumonitis. In this study, we show that TCRα(-/-) recipients, which lack αβ T cells but have γδ T cells and B cells, are significantly protected from the hepatitis and pneumonitis, but not the dermatitis, induced by adoptive transfer of scurfy lymphocytes. Cotransfer of γδ T cells, but not B cells, prevented hepatitis and pneumonitis in RAG(-/-) recipients of scurfy lymphocytes. γδ T cells in the TCRα(-/-) recipients of scurfy cells markedly expanded and expressed a highly activated (CD62L(lo)CD44(hi)) phenotype. The activated γδ T cells expressed high levels of CD39 and NKG2D on their cell surface. A high frequency of scurfy T cells in TCRα(-/-) recipients produced IL-10, suggesting that γδ T cells may enhance suppressor cytokine production from scurfy T cells in TCRα(-/-) recipients. This study indicates that γδ T cells may contribute to the maintenance of immunological homeostasis by suppressing autoreactive T cells in liver and lung.
