In this study, have demonstrated the expression of CB2 and TRPV1 in human and rodent skeletal muscle as potential receptor sites for the previously observed effects of AEA [19]. Drugs targeting CB1, CB2, FAAH and TRPV1 for the treatment of obesity, pain and inflammation are currently under development [26,42–44]. The expression of CB2, FAAH and TRPV1 along with CB1 in human and rodent skeletal muscle istherefore an important consideration in the development of these therapeutic targets. Endocannabinoids may have a complex role in skeletal muscle biology.
