Fig 1: Cytokines produced by iron-deficient and sufficient patientsPBMC of 48 TB patients (23 with iron deficiency, 25 with iron sufficiency) were isolated and stimulated with TB antigen CFP-10 and ESAT-6 peptides. Cytokines within culture supernate were measured using the BioLegend LEGENDplex kits and ELISA. Among these cytokines, IL-1β and IL-7 were much higher in iron deficiency TB (p = 0.029 for IL-1β and p = 0.014 for IL-7, Wilcoxon test). For TGF-β, the unit is ng/mL. Data were shown as mean with 95% CI. ∗, p < 0.05, ns, not significant.
