Abstract
IL-17-producing γδ T cells express oligoclonal Vγ4+ and Vγ6+ TCRs, mainly develop in the prenatal thymus, and later persist as long-lived self-renewing cells in all kinds of tissues. However, their exchange between tissues and the mechanisms of their tissue-specific adaptation remain poorly understood. Here, single-cell RNA-seq profiling identifies IL-17-producing Vγ6+ T cells as a highly homogeneous Scart1+ population in contrast to their Scart2+ IL-17-producing Vγ4+ T cell counterparts. Parabiosis demonstrates that Vγ6+ T cells are fairly tissue resident in the thymus, peripheral lymph nodes, and skin. There, Scart1+ Vγ6+ T cells display tissue-specific gene expression signatures in the sk..
