Abstract

Background & aims Liver regeneration after loss of hepatic tissue leads to hepatocyte and nonparenchymal cell proliferation and rapid restoration of liver parenchyma. Interleukin (IL)-6 is a key inducer of transcription factors involved in liver regeneration. Whenever IL-6 activates target cells, it binds to a specific IL-6 receptor (IL-6R). The IL-6/IL-6R complex then associates with the signal transducer gp130, leading to activation of intracellular signaling. Methods We have recently constructed the designer cytokine Hyper-IL-6 consisting of soluble IL-6R covalently linked to IL-6, which directly stimulates gp130 even in the absence of membrane-bound IL-6R. We compared the influence of IL-6 and Hyper-IL-6 on liver regeneration after partial hepatectomy in mice. Results The IL-6/soluble IL-6 fusion protein Hyper-IL-6, but not IL-6 alone, led to an earlier onset of hepatocellular proliferation resulting in an acceleration of liver weight restoration. Also, during liver regeneration, soluble IL-6R levels were increased. Conclusions These results emphasize a central role for IL-6 and soluble IL-6R in liver regeneration and indicate a possible therapeutic potential for the designer cytokine Hyper-IL-6 in clinical situations associated with liver regeneration such as acute hepatic failure or resection of chronically damaged liver tissue.

  • Although IL-6 classic signaling promotes compensatory hepatocyte proliferation, IL-6 trans-signaling is more important in liver regeneration.

    “Although the classic or cis-signaling of IL-6 is determined to promote the compensatory proliferation of hepatocytes, its trans-signaling in liver regeneration is more important [19, 25–27].”

    From The double-edged effects of IL-6 in liver regeneration, aging, inflammation, and diseases (2024) · cites this paper as [25]

    The Discussion (page unavailable) reports that IL-6 combined with soluble IL-6R accelerated hepatocyte proliferation and liver regeneration after partial hepatectomy in mice, whereas IL-6 alone did not significantly accelerate either outcome. This supports the comparison favoring trans-signaling in that model, but the paper does not establish that classic signaling itself promotes compensatory hepatocyte proliferation or that trans-signaling is generally more important across liver regeneration settings.

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.
