摘要："BackgroundEpigenetic remodeling at effector gene loci has been reported to be critical in regulating T cell differentiation and function. However, efforts to investigate underlying epigenetic mechanisms that control T cell behaviors have been largely hindered by very limited experimental tools, especially in humans.ResultsIn this study, we employed a flow cytometric assay to analyze histone acetylation at single-cell level in human T cells. The data showed that histone acetylation was increased during T cell activation. Among T cell subsets, terminally differentiated effector memory T (TEMRA) cells robustly producing effector cytokines were hyper-acetylated. Conversely, these TEMRA cells had lower expression levels of TCF-1, a key transcription factor for maintaining stem cell features. Pharmaceutical inhibition of histone acetylation using a small molecule C646 restrained the production of effector molecules, but retained stem cell-like properties in T cells after expansion.ConclusionsPer-cell histone acetylation is associated with terminal differentiation and poor stemness in human T cells. These observations suggest a new approach to enhance the stem cell-like properties of T cells and improve the efficacy of immunotherapy."
