Abstract

Myofibroblasts are the major source of extracellular matrix components that accumulate during tissue fibrosis, and hepatic stellate cells (HSCs) are believed to be the major source of myofibroblasts in the liver. To date, robust systems to genetically manipulate these cells have not been developed. We report that Cre under control of the promoter of Pdgfrb (Pdgfrb-Cre) inactivates loxP-flanked genes in mouse HSCs with high efficiency. We used this system to delete the gene encoding α(v) integrin subunit because various α(v)-containing integrins have been suggested as central mediators of fibrosis in multiple organs. Such depletion protected mice from carbon tetrachloride-induced hepatic fibrosis, whereas global loss of β₃, β₅ or β₆ integrins or conditional loss of β₈ integrins in HSCs did not. We also found that Pdgfrb-Cre effectively targeted myofibroblasts in multiple organs, and depletion of the α(v) integrin subunit using this system was protective in other models of organ fibrosis, including pulmonary and renal fibrosis. Pharmacological blockade of α(v)-containing integrins by a small molecule (CWHM 12) attenuated both liver and lung fibrosis, including in a therapeutic manner. These data identify a core pathway that regulates fibrosis and suggest that pharmacological targeting of all α(v) integrins may have clinical utility in the treatment of patients with a broad range of fibrotic diseases.

  • Small molecule inhibition and antibody blockade of integrin αvβ6 have both been shown to effectively attenuate biliary and non-biliary fibrogenesis with reduced proliferation of cholangiocyte-like progenitor cells and attenuated TGFβ1 activation.

  • Blocking TGF-β activation by targeting αv-containing integrins at the cell surface is a promising approach.

    “However, inhibiting the activation of TGF-β by targeting the αv-containing subset of integrins at the cell surface (e.g., integrins αvb1, αvβ3, αvβ5, αvβ6 and αvβ8) is promising.”
  • IL-17A signaling has a confirmed role in fibrosis development in multiple tissues, based on IL-17A- and IL-17RA-deficient mice and neutralizing monoclonal antibodies.

    “Experiments with IL-17A- and IL-17RA-deficient mice, as well as therapeutic studies with IL-17A neutralizing monoclonal antibodies confirmed a role for IL-17A signaling in the development of fibrosis in multiple tissues110–112,116–118”

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.
