IL1A and tuberculosis: Similarly, as shown in Fig 2B, the TB-antigen stimulated levels of TNF-α (GM of 2.077 pg/ml vs 10.31 pg/ml), IL-17 (GM of 2.6532 pg/ml vs 26.74 pg/ml), IL-1α (GM of 14.93 pg/ml vs 31.58 pg/ml) and IL-1β (GM of 24.72 pg/ml vs 59.52 pg/ml) were also significantly decreased in TBL-Ss+ compared to TBL Ss- mono infected individuals.
