Abstract

PURPOSE: To investigate the role of the IL-6 classic- and trans-signaling pathways in corneal sterile inflammation and wound healing. METHODS: To assess the production of inflammatory molecules by corneal fibroblasts treated with supernatant derived from necrotic corneal epithelial cells, the authors used an antibody array. Expressions of membrane IL-6 receptor (mIL-6R) and soluble IL-6R (SIL-6R) by fibroblasts and epithelial cells were detected with flow cytometry and RT-PCR. Expressions of signal transducer and activator of transcription 3 (STAT3), vascular endothelial growth factor (VEGF), and monocyte chemotactic protein-1 (MCP-1) by fibroblasts stimulated with IL-6 alone or IL-6/SIL-6R were determined by ELISA. The effect of IL-6 or IL-6/SIL-6R on epithelial cell migration was investigated in vitro by the scratch assay, whereas expressions of IL-6R and S100 A4 in the corneas of mice were detected by immunohistochemistry after incision of the corneal stroma. RESULTS: IL-1 derived from necrotic corneal epithelial cells induced the production of IL-6 by corneal fibroblasts. mIL-6R and SIL-6R mRNAs were expressed by both types of cells, although IL-6R protein at the cell surface was expressed only by epithelial cells. Expression of gp130 was detected in both types of cells. Activation of the IL-6 trans-signaling pathway induced the phosphorylation of STAT3, resulting in an increase of VEGF and MCP-1 production by corneal fibroblasts. Activation of the IL-6 classic-signaling pathway promoted the migration of corneal epithelial cells. IL-6R expression was also detected in activated fibroblasts and basal cells of the epithelium during the processes of wound healing in vivo. CONCLUSIONS: The IL-6 classic- and trans-signaling pathways have an important role in corneal sterile inflammation and wound healing.

  • IL6 contributes to wound healing both via proinflammatory actions and by promoting cell migration.

    “IL6 is important in wound healing, not only through proinflammatory effects but also by promoting cell migration (Ebihara, et al., 2011,Nasole, et al., 2014).”

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.
