“Cannabinoids protect neurons from excitotoxic injury…
Endogenous or exogenous cannabinoids have shown neuroprotective effects…
The main finding reported here is that cannabinoids protect neurons from excitotoxic injury by a mechanism that involves the activation of CB1R and inhibition of NOS and PKA….
Cannabinoid receptor agonist drugs protect neurons…
By identifying the signaling pathways responsible for cannabinoid effects in animal models of disease and their human counterparts, it may be possible to design more specific and therefore more efficacious cannabinoid-based therapies.”
