Blood expression of apoptotic genes as a function of TST response in the clinical groups.

<p>(A) <i>TNFR1</i>, (B) <i>TNFR2</i>, (C) <i>FLIPs</i>, (D) <i>FLICE</i>. TST positivity was defined as an induration >5 mm in diameter. Neg, TST induration <5 mm, Pos, TST induration ≥5 mm in diameter. The data shown are the median and ranges of mRNA levels normalized and expressed as a number of copies per 10⁵ copies of mRNA for the housekeeping gene, <i>HuPO</i>. Significant differences in gene expression between clinical groups are shown.
