Single cell RNA sequencing of Vγ4 and Vγ6 γδT cells from different tissue

IL17-producing γδ T cells (γδ T17) mainly develop in the prenatal phase and persist as long-living self-renewing effector cell in all kind of tissues. They express polyclonal T-cell receptors (TCR), comprising public Vγ4+ and Vγ6+ TCRs with germline-like rearrangements. In particular, Vγ6+ T cells have recently been found in a variety of tissues including enthesis, gingiva or skin. However, their exchange between tissues and the mechanisms of tissue-specific adaptation and residency remain poorly understood. Here, we profiled Vγ6+ T cells isolated from thymus, peripheral lymph nodes (pLN) and skin through single-cell RNA-seq technology and compared those to Vγ4+ T cells. Our data demonstrated that Vγ6+ T cells formed highly homogenous cell populations that could be separated by tissue-specific gene expression signatures. Sort Vγ4 and Vγ6 γδT cells from peripheral lymph nodes, ear skin and thymus, then do 3'-RNA single cell sequencing (10x genomics).
