This resulted in 114 genes (18% of total) with differences between LTBI and TB groups only after specific stimulation (TB Ag; 71, BCG; 28, IL-1β; 15) (Figure 1B and Supplementary Table S2), with TB Ag stimulation revealing significantly more differences than the other stimulations (Supplementary Table S3). The gene discussed is IL1B; the disease is tuberculosis.
