To better characterize the biological features of γδ blood T cells in psoriasis, we next assessed the transcriptional profile of flow-sorted γδ population by targeting several genes essential to development of innateness (ZBTB16, RUNX3, IL18R), type 17 response (CCR6, RORC), Th1/cytotoxic polarization (RUNX3, TBX21, EOMES), and tissue homing (CCR6, CCR10). This evidence concerns the gene IL18R1 and psoriasis.
