Abstract
Osteoarthritis (OA) is a chronic joint disease in which cartilage degeneration leads to chronic pain. The endocannabinoid system has attracted attention as an emerging drug target for OA. However, the therapeutic potential of cannabinoids is limited by psychoactive side-effects related to CB1 activation and tolerance development for analgesic effects. Beta-Caryophyllene (BCP) is a low-efficacy natural agonist of CB2 and a common constituent of human diet with well-established anti-inflammatory properties. The results presented herein show the anti-nociceptive and chondroprotective potential of BCP in an animal model of OA induced by intra-articular injection of monoiodoacetate (MIA). Behavioural assessment included pressure application measurement and kinetic weight bearing tests. Histological assessment of cartilage degeneration was quantified using OARSI scoring. Experiments established the dose-response effects of BCP and pharmacological mechanisms of the antinociceptive action dependent on CB2 and opioid receptors. Chronic BCP treatment was able to hamper cartilage degeneration without producing tolerance for the analgesic effects. The data presented herein show that BCP is able to produce both acute and prolonged antinociceptive and chondroprotective effects. Together with the safety profile and legal status of BCP, these results indicate a novel and promising disease-modifying strategy for treating OA.

Un instrument unique qui ne fournit pas seulement la mesure indépendante et automatisée du poids porté par chaque patte d'un rongeur (rat ou souris) évoluant librement, comme le Test de Distribution Pondérale Dynamique, mais génère aussi des courbes d'informations sur la distribution de cette force dans le temps, toujours indépendamment et pour chaque patte.

Un instrument révolutionnaire pour vos recherches en analgésie, nociception et neurosciences, particulièrement adapté aux travaux sur les maladies de Parkinson et d'Alzheimer, l'arthrite et les lésions du cerveau et de la moelle épinière.
