Epigenetic profiling reveals developmental traits of adult thymus-derived Vγ4+ γδ T cells


ABSTRACT: Recent advances in next-generation sequencing technologies elucidated gene regulatory networks and TCR signaling molecules underlying functional differentiation into γδ1 and γδ17 cells that now provide valid resources to define developing CD24+ γδ, γδ1 and γδ17 cells. The γδ1 cell subsets express key transcription factors of cytotoxicity and IFNγ-production, such as Tbx21 (encoding T-bet) and Eomes, as well as natural killer receptor (NKRs). Development of γδ17 cells is favorable in the early life period, regulated by Notch signaling and a network of transcriptional regulators including cMaf, Sox13, Blk, and Rorc that are essential for functional differentiation. However, detailed knowledge about molecular programs of Vγ4 cells, including their potential to become γδ1 or γδ17 cells during adult thymus development, is lacking. Here we employed transcriptional and epigenetic analysis of Vγ4 cells under steady-state conditions and after induction of de novo T cell development from adult thymus precursor cells.
