Peripheral tissue instruction is the primary determinant of CD8+ T cell pathogenicity: transcription profiling by RNA-seq of CD8+ effector T cells isolated from the blood and skin of HSCT patients developing acute pattern GVHD.

To determine whether murine GVHD associated tissue-specific signatures of donor CD8+ effector T cells are conserved at the same locations in humans developing GVHD, we compared the transcriptional profile of CD8+ T cells obtained simultaneously from the blood and skin of 5 patients developing acute pattern skin GVHD.
