Cytokine expression patterns during TB treatment in cured, failed and relapsed TB patients in South Africa. Heatmap of serum cytokine concentrations in 78 cured, 15 failed and 12 relapse patients at diagnosis, weeks 2, 4 and 26 of TB treatment. The heatmap was generated as in Fig. 2. Only cytokines detected in serum of all three patient groups are shown. Bright yellow (+2) indicates 4-fold upregulation from the mean (black) and bright blue (−3) indicates an 8-fold downregulation from the mean.
