Abstract

Background Myofibroblasts play a role in the airway remodeling response of bronchial asthma. IL-4 and IL-13 are possibly involved in the airway remodeling response by inducing extracellular matrix production by fibroblasts. However, the roles of these cytokines in inducing the phenotypic modulation of human lung fibroblasts (HLFs) to myofibroblasts and the intracellular signal have not been determined.Objective We examined the effect of IL-4 and IL-13 on inducing the phenotypic modulation of HLFs to myofibroblasts characterized by alpha-smooth muscle actin and examined the role of the mitogen-activated protein (MAP) kinase superfamily in inducing the myofibroblastic phenotype of the HLF to clarify these issues.Methods Phosphorylation and activities of c-Jun NH(2)-terminal kinase (JNK), p38 MAP kinase, and extracellular signal-regulated kinase (Erk) were examined by using Western blotting and in vitro kinase assay. Expression of alpha-smooth muscle actin in IL-4- and IL-13-stimulated HLFs was analyzed by means of Western blotting.Results The results showed that (1) IL-4 and IL-13 increased alpha-smooth muscle actin expression in a dose- and time-dependent manner; (2) IL-4 and IL-13 induced increases in JNK and Erk phosphorylation and activity but not p38 MAP kinase activity; (3) CEP-1347 and PD 98059 attenuated IL-4- and IL13-induced JNK and Erk activity, respectively; and (4) CEP-1347, but not PD 98059, attenuated IL-4- and IL-13-induced alpha-smooth muscle actin expression.Conclusion These results indicate that IL-4 and IL-13 are capable of inducing the phenotypic modulation of HLFs to myofibroblasts, and JNK, but not p38 MAP kinase and Erk, regulates IL-4- and IL-13-induced phenotypic modulation of HLFs to myofibroblasts.

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

  • IL-4 and IL-13 are pro-fibrotic.

    “In addition to these factors, both IL-4 and IL-13 are pro-fibrotic (150).”

    From Unraveling SSc Pathophysiology; The Myofibroblast (2018) · cites this paper as [150]

  • Both IL-4 and IL-13 induce αSMA expression in primary lung fibroblasts in a dose- and time-dependent manner.

    “Both cytokines induce αSMA expression in primary lung fibroblasts in a dose- and time-dependent manner (105, 150), and enhance the production of collagen type I in normal fibroblasts (108).”

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.
