Immune reconstitution of 25 patients by flow cytometry, showing major cell populations and their subsets over time. Median T-cell subsets are shown, with the predominant CD4⁺ and CD8⁺ subset being CD45RA^-CD62L^- effector memory cells. Additional subsets are visualized in supplemental Figure 1. DPI, day post 1st VST infusion; br, bright; cm, central memory; Conv, conventional; em, effector memory; emra, terminal effector memory.
