Stimulation of Toll-like receptors (TLRs) on macrophages and dendritic cells (DCs) by pathogen-derived products induces the production of cytokines, which play an important role in immune responses. Here, we investigated the role of the TPL-2 signaling pathway in TLR induction of interferon-β (IFN-β) and interleukin-10 (IL-10) in these cell types. It has previously been suggested that IFN-β and IL-10 are coordinately regulated after TLR stimulation. However, in the absence of TPL-2 signaling, lipopolysaccharide (TLR4) and CpG (TLR9) stimulation resulted in increased production of IFN-β while decreasing IL-10 production by both macrophages and myeloid DCs. In contrast, CpG induction of both IFN-α and IFN-β by plasmacytoid DCs was decreased in the absence of TPL-2, although extracellular signal-regulated kinase (ERK) activation was blocked. Extracellular signal-related kinase–dependent negative regulation of IFN-β in macrophages was IL-10–independent, required protein synthesis, and was recapitulated in TPL-2–deficient myeloid DCs by retroviral transduction of the ERK-dependent transcription factor c-fos.

The chemokine fractalkine (C–X3–C motif chemokine ligand 1, CX3CL1) and its receptor (C–X3–C motif chemokine receptor 1, CX3CR1) are known to mediate leukocyte chemotaxis, adhesion, and survival. In the liver, CX3CR1 is expressed on multiple cell types including monocytes and dendritic cells. However, the function of CX3CR1 on hepatic dendritic cells (HDCs) is still poorly understood. In the present study, we investigated the role of CX3CR1 on mouse HDCs during homeostasis and following acute liver injury. At homeostasis, CX3CR1 expression was detected amongst CD11b+/CD103− type 2 myeloid HDCs (mHDCs) and these cells were characterized by the production of interleukin-10 (IL-10). Mice treatment with the hepatotoxic agent carbon tetrachloride (CCl4) up-regulated liver IL-10 expression and stimulated the expansion of CX3CR1+ mHDCs which also showed a more mature phenotype. The absence of CX3CR1 in naïve CX3CR1gfp/gfp mice specifically reduced the CD11b+/IL-10+ mHDCs as compared with CX3CR1-proficient animals (CX3CR1+/gfp). Following CCl4 poisoning, the liver recruitment and maturation of CD11b+ mHDCs was significantly attenuated in CX3CR1gfp/gfp mice. Furthermore, these mice suffered more severe hepatic injury and inflammation than CX3CR1+/gfp mice and showed a delated recovery from liver damage. Such a worsening of liver injury in CX3CR1gfp/gfp mice was associated with an impaired up-regulation of hepatic IL-10 expression and a lower number of IL-10 producing CD11b+ mHDCs. Consistently, IL-10 inactivation enhanced hepatic injury and inflammation in CX3CR1+/gfp mice receiving CCl4. Altogether, these data indicate a novel role of the CX3CL1/CX3CR1 axis in liver type 2 mHDC functions, pointing out the importance of CX3CR1 in promoting IL-10-mediated anti-inflammatory actions of HDCs.
