“Cannabinoids have been shown to exert neuroprotective effects in a plethora of neurodegenerative conditions. Over the past decade, some studies demonstrate that cannabinoids can interact with nuclear peroxisome proliferator-activated receptors (PPARs). We investigated protective properties of WIN55212-2 (WIN, a non-selective cannabinoid receptor agonist) in beta-amyloid (Aβ)-induced neurodegeneration in rat hippocampus and possible involvement of PPAR-gamma (PPAR-γ).
WIN administration significantly improved memory function…
Our findings indicate that WIN exerts neuroprotective and anti-inflammatory actions against Aβ damage through both CB₁ and CB₂ receptors. Of great note, both direct and CB₁-mediated increase in PPAR-γ signaling also contributes to WIN-induced neuroprotection.”
