Analysis of the TB-Treated group according to time after clinical cure showed that this increase was only significant in patients treated more than 1 year ago, and we observed significantly higher IL-10 levels in unstimulated and stimulted culture supernatants in comparison with Active-TB patients (unstimulated: p = 0.0006, stimulated: p = 0.003) or Healthy Donors (unstimulated: p = 0.0003, stimulated: p = 0.0001). This evidence concerns the gene IL10 and tuberculosis.
