Abstract

Although hepatic fibrosis typically follows chronic inflammation, fibrosis will often regress after cessation of liver injury. In this study, we examined whether liver dendritic cells (DCs) play a role in liver fibrosis regression using carbon tetrachloride to induce liver injury. We examined DC dynamics during fibrosis regression and their capacity to modulate liver fibrosis regression upon cessation of injury. We show that conditional DC depletion soon after discontinuation of the liver insult leads to delayed fibrosis regression and reduced clearance of activated hepatic stellate cells, the key fibrogenic cell in the liver. Conversely, DC expansion induced either by Flt3L (fms–like tyrosine kinase–3 ligand) or adoptive transfer of purified DCs accelerates liver fibrosis regression. DC modulation of fibrosis was partially dependent on matrix metalloproteinase (MMP)–9, because MMP–9 inhibition abolished the Flt3L–mediated effect and the ability of transferred DCs to accelerate fibrosis regression. In contrast, transfer of DCs from MMP–9–deficient mice failed to improve fibrosis regression. Conclusion : Taken together, these results suggest that DCs increase fibrosis regression and that the effect is correlated with their production of MMP–9. The results also suggest that Flt3L treatment during fibrosis resolution merits evaluation to accelerate regression of advanced liver fibrosis. (Hepatology 2012;55:243–255)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
