Abstract
STRUCTURED ABSTRACT: Study Design: Descriptive and mechanistic investigation of the anti-inflammatory and anti-catabolic effect of resveratrol in intervertebral discs (IVDs) in vitro and of the analgetic effect in vivo.Objective: To determine whether resveratrol may be useful in treating nucleus pulposus (NP) mediated pain.Summary of Background Data: Proinflammatory cytokines seem to be key mediators in the development of NP mediated pain. Patients with discogenic or radiculopathic pain may substantially benefit from anti-inflammatory substances that could be used in a minimal-invasive treatment approach. Resveratrol, a polyphenolic phytoalexin found in red wine exhibits anti-inflammatory effects in various cell types and tissues, but no data exists so far with regards to the IVD in the context of low back and leg pain.Methods: In Part 1, the anti-inflammatory and anti-catabolic effect of resveratrol was investigated in a cell culture model on IL-1β prestimulated human IVD cells on the gene and protein expression level. In Part 2, the molecular mechanisms underlying the effects observed upon resveratrol treatment were investigated (Toll-like receptors, NF-κB, SIRT1, MAP Kinases p38/ERK/JNK). In Part 3, the analgetic effects of resveratrol were investigated in vivo using a rodent model of radiculopathy and von Frey filament testing. All quantitative data was statistically evaluated either by Mann-Whitney-U Test or by One way ANOVA and Bonferroni Post-hoc testing (p < 0.05).Results: In vitro, resveratrol exhibited an anti-inflammatory and anti-catabolic effect on the mRNA and protein level for IL-6, IL-8, MMP1, MMP3 and MMP13. This effect does not seem to be mediated via the MAP Kinase pathways (p38, ERK, JNK) or via the NF-κB/SIRT1 pathway, although Toll-like receptor 2 was regulated to a minor extent. In vivo, resveratrol significantly reduced pain behavior triggered by application of NP tissue on the dorsal root ganglion for up to 14 days.Conclusions: Resveratrol was able to reduce levels of proinflammatory cytokines in vitro and showed analgetic potential in vivo. A decrease in proinflammatory cytokines may possibly be the underlying mechanism of pain reduction observed in vivo. Resveratrol seems to have considerable potential for the treatment of NP mediated pain and may thus be an alternative to other currently discussed (biological) treatment options.
