Helper versus cytotoxic T lineage decision in the thymus has been studied as a model for silencing of alternative lineage genes. While the transcription factor RUNX3 is required for the initiation of Cd4 silencing in developing CD8 T cells, it is unknown how silencing of Cd4 and other helper T lineage genes is maintained. We show that the histone methyltransferase G9a is necessary for silencing of helper T lineage genes in proliferating mouse CD8 T cells. Despite normal initial Cd4 downregulation, G9a-deficient CD8 T cells de-repress Cd4 and other helper lineage genes during repeated division in lymphopenia or in response to tumor Ag. However, G9a was dispensable for continued silencing of those genes in CD8 T cells that respond to infection by L. monocytogenes. These results demonstrate that G9a facilitates maintenance of cellular identity of CD8 T cells during cell division, which is further reinforced by inflammatory signals.
