The median granulysin and IFN-γ levels tended to increase after treatment (TB, PPD: before treatment, 0.595 ng/mL; after treatment, 0.775 ng/mL, p = 0.311, and H37Ra: before treatment, 0.513 ng/mL; after treatment, 0.881 ng/mL, p = 0.507, Figure 2a). The gene discussed is IFNG; the disease is tuberculosis.
