Abstract Cannabis is the most widely used recreational drug in the United States and regular use has been linked to deficits in attention and memory. However, the effects of regular…
Condition: Nervous System
Cannabidiol modulates excitatory-inhibitory ratio to counter hippocampal hyperactivity
SUMMARY Cannabidiol (CBD), a non-euphoric component of cannabis, reduces seizures in multiple forms of pediatric epilepsies, but the mechanism(s) of anti-seizure action remain unclear. In one leading model, CBD…
Mast cells express a peripheral cannabinoid receptor with differential sensitivity to anandamide and palmitoylethanolamide
Abstract Mast cells are multifunctional bone marrow-derived cells found in mucosal and connective tissues and in the nervous system, where they play important roles in tissue inflammation and in…
Direct suppression of autoreactive lymphocytes in the central nervous system via the CB2 receptor
Abstract The cannabinoid system is now recognized as a regulator of both the nervous and immune systems. Although marijuana has been used for centuries for the treatment of a variety…
Cannabinoid Type 2 Receptors Mediate a Cell Type Specific Plasticity in the Hippocampus
Endocannabinoids (eCBs) exert major control over neuronal activity by activating cannabinoid receptors (CBRs). The functionality of the eCB system is primarily ascribed to the well-documented retrograde activation of presynaptic CB1Rs….
Cannabinoid Modulation of Neuroinflammatory Disorders
In recent years, a growing interest has been dedicated to the study of the endocannabinoid system. The isolation of Cannabis sativa main psychotropic compound, Δ9 -tetrahydrocannabinol (THC), has led to…
Therapeutic Potential of Cannabinoids in CNS Disease
Abstract The major psychoactive constituent of Cannabis sativa, delta(9)-tetrahydrocannabinol (delta(9)-THC), and endogenous cannabinoid ligands, such as anandamide, signal through G-protein-coupled cannabinoid receptors localised to regions of the brain associated with…
Phytocannabinoids as novel therapeuticagents in CNS disorders
Abstract The Cannabis sativa herb contains over 100 phytocannabinoid (pCB) compounds and has been used for thousands of years for both recreational and medicinal purposes. In the past two decades,…
Opposite Effects of D-9-Tetrahydrocannabinol and Cannabidiol on Human Brain Function and Psychopathology
D-9-tetrahydrocannabinol (D-9-THC) and Cannabidiol (CBD), the two main ingredients of the Cannabis sativa plant have distinct symptomatic and behavioral effects. We used functional magnetic resonance imaging (fMRI) in healthy volunteers…
Non-psychoactive CB2 cannabinoid agonists stimulate neural progenitor proliferation
Cannabinoids, the active components of marijuana and their endogenous counterparts, act on the brain and many other organs through the widely expressed CB1 cannabinoid receptor. In contrast, the CB2 cannabinoid…
