Beneficial effects of cannabinoid receptor type 2 (CB2R) in injured skeletal muscle post-contusion.

“The aim of the current study was to investigate the effects of cannabinoid receptor type 2 (CB2R) on the repair process of injured skeletal muscle, which could potentially lay solid foundations as a novel target for curing muscular fibrosis in future…

These results revealed multiple effects of CB2R in systematically inhibiting fibrotic formation and improving muscle regeneration, alongside its potential for clinical application in patients with skeletal muscle injuries and diseases.”

Cannabinoid CB1 receptor antagonists as potential pharmacotherapies for drug abuse disorders.


“Since the discovery of the cannabinoid CB1 receptor (CB1R) in 1988, and subsequently of the CB2 receptor (CB2R) in 1993, there has been an exponential growth of research investigating the functions of the endocannabinoid system. The roles of CB1Rs have been of particular interest to psychiatry because of their selective presence within the CNS and because of their association with brain-reward circuits involving mesocorticolimbic dopamine systems. One potential role that has become of considerable focus is the ability of CB1Rs to modulate the effects of the drugs of abuse. Many drugs of abuse elevate dopamine levels, and the ability of CB1R antagonists or inverse agonists to modulate these elevations has suggested their potential application as pharmacotherapies for treating drug abuse disorders. With the identification of the selective CB1R antagonist, rimonabant, in 1994, and subsequently of other CB1R antagonists, there has been a rapid expansion of research investigating their ability to modulate the effects of the drugs of abuse. This review highlights some of the preclinical and clinical studies that have examined the effects of CB1R antagonists under conditions potentially predictive of their therapeutic efficacy as treatments for drug abuse disorders.”
