Immune recovery over time and CDH17 expression in thymic epithelial cells. (A) T-cell numbers. (B) CD8 T-cell subsets. (C) CD4 T-cell subsets. (D) TRECs. (E) B and NK cell numbers. (F) Immunoglobulin levels. (G) CDH17 expression in the human thymus is restricted to the population of mature medullary epithelial cells (mTEChi) as shown by quantitative reverse transcription PCR analysis. mTEChi is a heterogeneous population of thymic epithelial cells that primarily consists of functionally mature, AIRE-expressing cells.
