Abstract

Epineurial fibrosis, fiber loss, limited reproducibility of recordings and variability of stimulation conditions have been documented after extraneural cuff electrode implantation. These morphological and electrophysiological modifications could be due to the local release of cytokines. We report the expression of two cytokines, tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta1 (TGF-beta1) in the rat sciatic nerve after 'cuff' implantation for 18 h, 7 days and 1 month. Immunohistochemical and Western blot analyses showed a transient upregulation of TNF-alpha, during the first week, and a prolonged increase of TGF-beta1, over the 1-month period duration of this study. Considering the known pro-inflammatory roles of TNF-alpha and the pro-fibrotic action of TGF-beta, our results strongly suggest that these cytokines may contribute to nerve alterations occurring within the acute and sub-acute phases after cuff electrode implantation.

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.
