FIGURE 2: Comparisons of PD-L1, DNMTs, and TETs expression in PBMCs from patients with active TB with various clinical presentations and treatment outcomes. The data in bar charts are mean values. Error bars are standard errors. Differences between groups were compared using the Mann– Whitney U test. PD-L1 – programmed death-ligand 1; DNMTs – DNA methyltransferases; TETs – ten eleven translocation methylcytosine dioxygenases.
