POH1 inhibits inflammasome-induced pro-IL-1β processing. a-c BMDMs from Poh1Δ/+ and Poh1Δ/Δ mice were primed with LPS for 12–14 h and then stimulated with ATP (0.5 h), nigericin (Nig, 0.5 h), poly(dA:dT) (5 h) or flagellin (5 h) as indicated, a IL-1β, b IL-6 and c TNFα levels in supernatants were analysed by ELISA. d-f BMDMs lentivirally transduced with control (Vector) or POH1 were stimulated as in a, d IL-1β, e IL-6 and f TNFα levels in supernatants were analysed by ELISA. g, h BMDMs g derived from Poh1Δ/+ and Poh1Δ/Δ mice or h infected by indicated lentiviruses were treated as in a, the cell lysates (CL) and supernatants (SN) were collected and immunoblotted with the indicated antibodies. Similar results were obtained from three independent experiments. The results represent the mean ± s.d. of three independent sets of experiments. **p < 0.01, ***p < 0.001 (two-tailed Student’s t-test)
