a, Nrf2-response genes in DI-treated BMDMs. b, c, Western blots of Nrf2 and Nrf2 targets in DI-treated (b) or LPS-stimulated (c) BMDMs. d, The chemical structures of DI-GSH and Ita-GSH. e, DI-GSH levels in the media of DI-treated BMDMs, mean of n = 2 cultures. f, Itaconate (left) and Ita-GSH (right) levels in BMDMs, mean ± s.e.m., n = 3 cultures. g, GSH levels in DI-treated BMDMs, mean of n = 2 experiments. h, i, Cytokine levels in BMDMs treated as indicated and LPS-stimulated for 4 h (h) and 24 h (i); mean ± s.e.m., n = 3 experiments. Western blots are representatives of three experiments. For gel source data, see Supplementary Fig. 1. Statistical tests used were two-tailed t-tests. AT, α-tocopherol; MT, MitoTEMPO.
