Also, there was a tendency for lower MFI of IL-1b-positive hMDMs among TB patients than among LTBI contacts after 24 hr stimulation by ESAT-6 1 μg/ml (64.0 ± 19.6 vs. 89.8 ± 44.9, P = 0.124) and ESAT-6 5 μg/ml (36.5 ± 9.9 vs. 84.0 ± 62.1, P = 0.163). The gene discussed is IL1B; the disease is tuberculosis.
