Correlations between the number of TRECs, the relative number of CD4⁺ naive T-cells, and TCRBV diversity 1 year or more after transplantation.

(A) Correlations between the number of TREC/μg CD3⁺ DNA (x-axis) and relative number of CD4⁺ naive T cells (y-axis), and (B) between the number of TREC/μg CD3⁺ DNA (x-axis) and TCRBV diversity expressed as percentages of polyclonal BV families in the same sample (y-axis).
