We also found several types of unconventional T cells, including both resting (LEF1, TCF7, and XCL1) and effector (PRF1 and GNLY) γδ T cells, which have been indicated in the pathogenesis of both human uveitis and animal models,17,18,19 as well as a mixed cluster of other unconventional T cells (including MAIT cells expressing KLRB1, ZBTB16, and TRAV1-2). Here, XCL1 is linked to uveitis.
