No statistically significant differences between the non-GVHD and the GVHD groups were found regarding frequencies of naïve (CD45RO−CCR7+; median 22.1% versus 43.3%; p = 0.165), central memory (CD45RO+CCR7+; median 12.6% versus 8.7%; p = 0.306), effector memory (CD45RO+CCR7−; median 35.9% versus 28%; p = 0.259), or terminally differentiated T-cells (CD45RO−CCR7−; median 21.7% versus 18.3%; p = 0.620). Here, CCR7 is linked to graft versus host disease.
