AC-induced inhibition of TNFα secretion by NOD DCs is mediated by MerTK-dependent PI3K signaling. (A) NOD and NOD.MerTK^KD BMDCs were pretreated with ACs for 3 hours, stimulated with LPS as in Figure 1, and TNFα secretion was measured via ELISA. (B) NOD BMDCs were incubated with 200 nM Wort or 50 μM LY for 1 hour, treated with ACs and LPS, and TNFα secretion was measured as above. Error bars indicate SE.
