An update on peroxisome proliferator-activated receptor (PPAR) activation by cannabinoids.

“Some cannabinoids activate the different isoforms of peroxisome proliferator-activated receptors (PPARs; α, β and γ), as shown through the use of reporter gene assays, binding studies, selective antagonists and knockout studies.

Activation of all isoforms, but primarily PPARα and γ, mediate some (but not all) of the analgesic, neuroprotective, neuronal function modulation, anti-inflammatory, metabolic, anti-tumoral, gastrointestinal and cardiovascular effects of some cannabinoids, often in conjunction with activation of the more traditional target sites of action such as CB1 , CB2 and TRPV1.

PPARs also mediate some of the effects of inhibitors of endocannabinoid degradation or transport. Cannabinoids may be chaperoned to the PPARs by fatty acid binding proteins (FABPs).

The aim of this review is to update the evidence supporting PPAR activation by cannabinoids, and review the physiological responses to cannabinoids that are mediated, and not mediated, by PPAR activation.”
