Abstract

This study examines intracellular signaling events associated with the activation of chondrocytes by the cytokine interleukin-17 (IL-17). Stimulation of normal human articular chondrocytes with IL-17 induced nitric oxide (NO) production, concomitant with an increase in transcripts and de novo translation products of the inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) genes. Several other genes associated with inflammation and cartilage degradation, such as IL-1beta, IL-6, and stromelysin, were also up-regulated in IL-17-treated chondrocytes. Among signaling events displaying early response to IL-17 in chondrocytes were the mitogen-activated protein (MAP) kinases ERK1, ERK2, JNK, and p38. DNA binding activity of NF-kappaB was also significantly induced. IL-17 effects on NO release, as well as iNOS, COX-2, and IL-6 protein expression, were inhibited by the anti-inflammatory drug dexamethasone. Importantly, dexamethasone blunted IL-17-dependent activation of MAP kinases, suggesting a mechanistic relationship between these activities and the aforementioned gene expression responses. Similar effects of a lesser extent were observed with the p38-specific inhibitor SB203580. These results suggest that IL-17 activation of chondrocytes is associated with and depends at least in part on the activation of MAP kinases and NF-kappaB.

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.
