5 Fig 4 Reversion of CGD inflammatory status by rapamycin. A, CD14+ monocytes from patients with CGD (n = 15, 18 samples) and HCs (n = 7, 7 samples) were differentiated into macrophages with (gray bars) or without (DMSO, open bars) rapamycin. Supernatant were collected at day +6 after differentiation, and cytokines were analyzed by using a cytometric bead assay (MACSPlex) or ELISA. B, MDMs from patients with CGD (n = 12) and HCs (n = 5) were stimulated for 24 hours with 100 ng/mL LPS in the presence of 10 nmol/L rapamycin (gray bars) or not (DMSO, open bars). Supernatant were collected for cytokines analysis through a cytometric bead assay (MACSPlex) or ELISA. C, MDMs from patients with CGD and HCs were primed with LPS and stimulated for 30 minutes with ATP in the presence or not of 10 mmol/L rapamycin. Caspase-1 activity was determined by using fluorescent inhibitor of active caspase-1 (FLICA). Numbers above bracketed lines indicate percentage of cells with active caspase-1.

Supernatants were then collected for cytokine analysis by using a cytometric bead assay (MACSPlex). F and G, CD14+ monocytes from patients with CGD (n = 8) were treated for 24 hours with 10 nmol/L rapamycin and increasing dose of anakinra (ie, 0, 40, and 400 ng/mL) before 4 hours of stimulation with LPS. Monocytes were then analyzed for IL-1β (Fig 4, F) and TNF-α secretion (Fig 4, G). *P < .05, **P < .01, and ***P < .001, Mann-Whitney U test or Wilcoxon paired t test.
