Endogenous interferon-γ is required for efficient skeletal muscle regeneration

Abstract

The inflammatory response is thought to play important roles in tissue healing. The hypothesis of this study was that the inflammatory cytokine interferon (IFN)-gamma is produced endogenously following skeletal muscle injury and promotes efficient healing. We show that IFN-gamma is expressed at both mRNA and protein levels in skeletal muscle following injury, and that the time course of IFN-gamma expression correlated with the accumulation of macrophages, T-cells, and natural killer cells, as well as myoblasts, in damaged muscle. Cells of each type were isolated from injured muscle, and IFN-gamma expression was detected in each cell type. We also demonstrate that administration of an IFN-gamma receptor blocking antibody to wild-type mice impaired induction of interferon response factor-1, reduced cell proliferation, and decreased formation of regenerating fibers. IFN-gamma null mice showed similarly impaired muscle healing associated with impaired macrophage function and development of fibrosis. In vitro studies demonstrated that IFN-gamma and its receptor are expressed in the C2C12 muscle cell line, and that the IFN-gamma receptor blocking antibody reduced proliferation and fusion of these muscle cells. In summary, our results indicate that IFN-gamma promotes muscle healing, in part, by stimulating formation of new muscle fibers.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The timing of inflammatory responses can strongly influence the kinetics and extent of muscle regeneration.

    “These studies showed that the timing of inflammatory responses can have profound effects on the kinetics and extent of regeneration69, findings confirmed by experiments using antibodies to block inflammatory cytokines70,71.”
  • Skeletal muscle Mp express iNOS mRNA at 5 days after chemically induced injury but do not express iNOS at any time-point after laceration injury.

    “Studies from our own laboratory have produced contradictory data in two different mouse muscle injury models: skeletal muscle Mp express iNOS mRNA at 5 days after chemically induced injury [57] but do not express iNOS at any time-point after laceration injury (unpublished results).”

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.
