BTLA+ mDCs in active TB show an increased production of IL-4 and TGF-β compared with those from HCs. As IL-4, IL-6, and TGF-β produced by mDCs affect the polarization of Th cells, we sought to investigate whether BTLA expression affects IL-4, IL-6, and TGF-β production in mDCs. (A,D,G) show the mean frequencies of IL-4, IL-6, and TGF-β producing mDCs in BTLA+ and BTLA− DCs from HCs (n = 10). (B,E,H) show the mean frequencies of IL-4, IL-6, and TGF-β producing mDCs in BTLA+ and BTLA− DCs from TB patients (n = 12 or 14). (C,F,I) show the comparison of IL-4, IL-6, and TGF-β producing mDCs in BTLA+ and BTLA− mDCs between HC and APT patients, respectively. The P values are shown in each column (Student t-test). *P < 0.05, **P < 0.01, ***P < 0.001.
