BACKGROUND AND AIMS
Beta-caryophyllene (BCP) is a plant-derived FDA approved food additive with anti-inflammatory properties. Some of its beneficial effects in vivo reported to involve activation of cannabinoid 2 receptors (CB2) that are predominantly expressed in immune cells. Herein, we evaluated the translational potential of BCP using a well-established model of chronic and binge alcohol-induced liver injury.
METHODS
In this study we investigated the effects of BCP on liver injury induced by chronic plus binge alcohol feeding in mice in vivo by using biochemical assays, real-time PCR and histology analyses. Serum and hepatic BCP levels were also determined by GC/MS.
RESULTS
Chronic treatment with BCP attenuated the chronic and binge alcohol-induced liver injury and inflammation by attenuating the pro-inflammatory phenotypic `M1` switch of Kupffer cells and by decreasing the expression of vascular adhesion molecules ICAM-1, E-Selectin and P-Selectin, as well as the neutrophil infiltration. It also beneficially influenced hepatic metabolic dysregulation (steatosis, protein hyperacetylation, and PPAR-ɑ signaling). The above mentioned protective effects of BCP against alcohol-induced liver injury were attenuated in CB2 knockout mice, indicating that the beneficial effects of this natural product in liver injury involve CB2 receptor activation. Following acute or chronic administration BCP was detectable both in the serum and liver tissue homogenates but not in the brain.
CONCLUSIONS
Given the safety of BCP in humans this food additive has a high translational potential in treating or preventing hepatic injury associated with oxidative stress, inflammation and steatosis.
