In this material, CD94+ total T-cells were found in higher frequencies in the non-GVHD group for naïve memory T-cells (median 5.2% versus 1.2%; p = 0.018; Figure 2(a)) and for terminally differentiated T-cells (median 33.7% versus 13.8%; p = 0.018; Figure 2(b)) as compared to the GVHD group. The gene discussed is KLRD1; the disease is graft versus host disease.
