Memory T lymphocytes are distinct from antigen-inexperienced naïve T cells in that memory T cells can respond more rapidly when they re-encounter a pathogen. Work over the past decade has begun to define the epigenetic underpinnings of the transcriptional component of the memory T cell response. An emerging theme is the persistence of an active chromatin signature at relevant gene loci in resting memory T cells, even when those genes are transcriptionally inactive. This gives strength to the concept of gene poising, and has shown that memory T lymphocytes are an ideal model in which to further define various mechanisms of epigenetic poising.
