Figure 8. Influence of low intracellular iron on LPS-induced cytokine expression.

Figure 8

Based on the effects of Hfe deficiency and iron chelation on responses to TLR2, TLR3, and TLR4 stimulation, low intracellular iron is likely to impair TLR4 signaling at a step in the TRAM/TRIF pathway proximal to TRIF. IRF3, IFN regulatory factor 3.
