Visualization of differences in IFN-γ production in response to
peptide pools using heatmaps in individuals from Belarus. Darker colors (red) represent higher and lighter colors (white) lower INF-γ production. Top panel: Healthy individuals (n = 15); Middle panel: Individuals recovered from TB (15 =); Bottom panel: TB+ patients (n = 15) from Belarus. The negative controls and constitutive IFN-γ production is subtracted.
