“Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease characterized by joint inflammation and cartilage destruction.
In this study we assessed the ability of WIN to modulate cytokine and MMP-3 production in SFs over a wide concentration range and identified specific receptor targets that mediate the effects of this synthetic cannabinoid.
The synthetic cannabinoid WIN in low concentrations exhibits anti-inflammatory effects in synovial fibroblasts independent of CB1 and CB2 while CB2 and yet unidentified receptor targets are responsible for WIN effects in micromolar concentrations.
Our results indicate a TRPV1/TRPA1 dependent mechanism of SF regulation that might be coupled to cellular energy status and calcium content.
In this report we demonstrated anti-inflammatory effects of the synthetic cannabinoid WIN in low and high concentrations.
Furthermore, this study demonstrated anti-inflammatory effects via modulation of TRP channels by WIN. Together, inactivation of TRPs and activation of cannabinoid receptors might also reduce the sensation of pain, which further underlines the potential of WIN in the treatment of chronic inflammation.”
