Abstract

Advanced hepatic fibrosis, driven by the activation of hepatic stellate cells (HSCs), affects millions worldwide and is the strongest predictor of mortality in nonalcoholic steatohepatitis (NASH); however, there are no approved antifibrotic therapies. To identify antifibrotic drug targets, we integrated progressive transcriptomic and morphological responses that accompany HSC activation in advanced disease using single-nucleus RNA sequencing and tissue clearing in a robust murine NASH model. In advanced fibrosis, we found that an autocrine HSC signaling circuit emerged that was composed of 68 receptor-ligand interactions conserved between murine and human NASH. These predicted interactions were supported by the parallel appearance of markedly increased direct stellate cell-cell contacts in murine NASH. As proof of principle, pharmacological inhibition of one such autocrine interaction, neurotrophic receptor tyrosine kinase 3–neurotrophin 3, inhibited human HSC activation in culture and reversed advanced murine NASH fibrosis. In summary, we uncovered a repertoire of antifibrotic drug targets underlying advanced fibrosis in vivo. The findings suggest a therapeutic paradigm in which stage-specific therapies could yield enhanced antifibrotic efficacy in patients with advanced hepatic fibrosis.

  • Recent single-cell human liver studies have largely focused on chronic liver disease rather than ALF, with emphasis on non-parenchymal cell populations.

  • Our single-nuclear RNA-seq in murine MASH models and MASH patients showed enrichment of myofibroblast pathways regulating ECM production and cell migration, including MMPs, TIMPs, and LOXLs.

    “We recently used single nuclear RNA-seq in murine MASH models and patients with MASH to demonstrate enrichment of pathways in myofibroblasts that regulate extracellular matrix production and cell migration, including matrix metalloproteinase (MMPs), tissue inhibitors of metalloproteinases (TIMPs), and lysyl oxidases (LOXLs) (47-49), similar to earlier studies of mouse fibrosis and human cirrhosis”
  • Our single-nucleus RNA-seq profiling of FAT-MASH macrophages showed no enrichment of ECM-related pathways, only induction of MMP2, MMP12, and MMP14 and decreased COL18A1.

    “Our profiling of FAT-MASH macrophages using single nucleus RNA-seq showed no enrichment of ECM-related pathways, only induction of a few select matrix metalloproteinases (MMP2, matrix metalloproteinase 12 (MMP12), matrix metalloproteinase 14 (MMP14)) and decreased collagen type 18 alpha 1 (COL18A1) (48).”
  • Detection of both quiescent and activated HSCs in mouse liver injury models by single-cell RNA-seq supports HSC activation as a driver of fibrosis across etiologies, including MASH.

    “The detection of both quiescent and activated HSCs in mouse liver injury models using single cell RNA-seq reinforces HSC activation as a driver of fibrosis common across etiologies that includes MASH (46-50).”
  • Although activated HSCs are the primary fibrogenic cells in MASH, single-cell methods have identified an expanded list of fibrogenic drivers expressed by activated HSCs that could be antifibrotic drug targets.

    “Although activated HSCs are the primary fibrogenic cells in MASH, these methods have identified an expanded list of fibrogenic drivers expressed by activated HSCs that could represent antifibrotic drug targets (42, 48, 49, 125).”

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.
