Abstract

Objective This study was designed to investigate whether IL-17 can regulate the expression of the MMP/TIMP system, the OPG/RANK/RANKL system, or type-I and type-III collagen fibers in a rat model of isoproterenol-induced heart failure (HF). We also investigated the effect of IL-17 on myocardial fibrosis in this model.Methods HF was induced in Wistar-Kyoto rats by hypodermic injection of isoproterenol (ISO) twice every 24 h. After 2 months, the surviving rats were divided into three groups: monoclonal Anti-IL-17 Ab (100 microg/day), IgG (100 microg/day) or PBS were injected five times every 48 h (i.p.). One day after the last injection, all of the rats were sacrificed. H&E and Masson staining were used to evaluate myocardial fibrosis, and immunohistochemistry was used to measure the levels of MMP-1, TIMP-1, TIMP-4, OPG, RANKL, type-I and type-III collagen fibers. We also treated adult rat cardiac fibroblasts with IL-17 (10 ng/ml), IL-17 (10 ng/ml)+OPG (10 ng/ml), IL-17 (10 ng/ml)+anti-RANKL Ab (100 ng/ml), or PBS for 24 h, realtime RT-PCR was used to measure the expressions of MMP-1.Results The expressions of MMP-1, RANKL, and type-I and -III collagen fibers decreased, and the expressions of TIMP-1, TIMP-4, and OPG increased in the Anti-IL-17 group compared to controls. H&E and Masson staining revealed that blockade of IL-17 can improve myocardial fibrosis in HF. IL-17 increased the expression of MMP-1 in cardiac fibroblasts, and OPG and anti-IL-17 Ab could inhibit this function partly. Thus, IL-17 was dependent on the RANKL/OPG system to induce MMP-1 partly.Conclusion Our study demonstrates the contribution of IL-17 to myocardial fibrosis in isoproterenol-induced HF. IL-17 can regulate the RANKL/OPG and MMP/TIMP systems in this model. The RANKL/OPG system is one of intermediaries between IL-17 and MMP-1 in cardiac fibroblasts. As a harmful cytokine, anti-IL-17 treatment is a potential therapeutic strategy in HF.

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.
