Recovery of T-cell subsets and T-cell function in adult CBT recipients. (A) CD3⁺, CD4⁺, CD8⁺, CD4⁺CD45RA⁺ T cells. (B) PHA responses. (C) CD4⁺ and CD4⁺ T-cell subsets (naive, CM, EM, effector). (D) CD8⁺ and CD8⁺ T-cell subsets (naive, CM, EM, effector). Curves are Loess-smoothed averages. In panels C and D, Loess-smoothed curves for total CD4⁺ and total CD8⁺ T cells, respectively, are based on values from the time points of which the extended immunophenotyping panel was also performed.
