We identified two predictive biomarkers of relapse (CD45RO T cells and frequency of Tregs), four predictive biomarkers of GVHD (CD45RO T cells and the frequency of Tregs, CD8, and DPTs), and two predictive biomarkers of ≥ grade 2 GVHD (frequency of Tregs and DPTs) (Fig. 1, C and D). The gene discussed is CD8A; the disease is graft versus host disease.
