Control of pain initiation by endogenous cannabinoids

The potent analgesic effects of cannabis-like drugs and the presence of CB1-type cannabinoid receptors in pain-processing areas of the brain and spinal cord, indicate that endogenous cannabinoids such as anandamide may contribute to the control of pain transmission within the central nervous system (CNS). Here we show that anandamide attenuates the pain behaviour produced by chemical damage to cutaneous tissue by interacting with CB1-like cannabinoid receptors located outside the CNS…

Pain modulation by release of the endogenous cannabinoid anandamide.
Findings indicate that the endogenous cannabinoid anandamide plays an important role in a cannabinergic pain-suppression system existing within the dorsal and lateral PAG, and may have relevance for the treatment of pain, particularly in instances where opiates are ineffective.

Cannabinoids mediate analgesia largely via peripheral type 1 cannabinoid receptors in nociceptors
It is concluded that the contribution of CB1-type receptors expressed on the peripheral terminals of nociceptors to cannabinoid-induced analgesia is paramount, which should enable the development of peripherally acting CB1 analgesic agonists without any central side effects.
The endocannabinoid system and pain.
The roles of anandamide and 2-arachidonoylglycerol, released under physiological conditions, in modulating nociceptive responding at different levels of the neuraxis will be emphasized in this review.
Cannabinoid CB2 Receptor-Mediated Anti-nociception in Models of Acute and Chronic Pain
This review focuses on the analgesic potential of CB2 receptor agonists for inflammatory, post-operative and neuropathic pain states and discusses their possible sites and mechanisms of action.

The data indicating that with cannabinoid/opioid therapy one may be able to produce long-term antinociceptive effects at doses devoid of substantial side effects, while preventing the neuronal biochemical changes that accompany tolerance are summarized.
Cannabinoid mechanisms of pain suppression.
Evidence supporting a role for cannabinoids in suppressing pain at spinal, supraspinal, and peripheral levels is examined and the potential of exploiting cannabinoid antinociceptive mechanisms in novel pharmacotherapies for pain is discussed.


A second endogenous cannabinoid that modulates long-term potentiation
2-AG activates neuronal cannabinoid receptors as a full agonist, and prevents the induction of long-term potentiation at CA3–CA1 synapses, indicating that 2-AG is a second endogenous cannabinoid ligand in the central nervous system.
Hypoactivity of the Spinal Cannabinoid System Results in NMDA-Dependent Hyperalgesia
Evidence for tonic modulation of basal thermal nociceptive thresholds by the spinal cannabinoid system is provided and hypoactivity of the spinal cannabinoids system results in an NMDA-dependent hyperalgesia and thus may participate in the etiology of certain chronic pain states.
Molecular characterization of a peripheral receptor for cannabinoids
The cloning of a receptor for cannabinoids is reported that is not expressed in the brain but rather in macrophages in the marginal zone of spleen, which helps clarify the non-psychoactive effects of cannabinoids.
Formation and inactivation of endogenous cannabinoid anandamide in central neurons
It is reported that anandamide is produced in and released from cultured brain neurons in a calcium ion-dependent manner when the neurons are stimulated with membrane-depolarizing agents, indicating that multiple biochemical pathways may participate in an andamide formation in brain tissue.

These studies indicate that the immune system can interact with peripheral sensory-nerve endings to inhibit pain and intrinsic modulation of nociception can occur at the peripheral terminals of afferent nerves.

The potencies of a series of natural and synthetic cannabinoids as competitors of [3H]CP 55,940 binding correlated closely with their relative potencies in several biological assays, suggesting that the receptor characterized in the in vitro assay is the same receptor that mediates behavioral and pharmacological effects of cannabinoids, including human subjective experience.
