What are endocannabinoids? THC and WIN are examples of exogenous cannabinoid receptor ligands, but the body makes its own ligands, too, and these are referred to as endocannabinoids. Two of the best-characterized endocannabinoids are anandamide and 2-arachidonylglycerol (2AG). Other candidate endocannabinoids have been identified but which, if any, of these compounds are physiologically relevan...

conclusions the important role played by endocannabinoid system promises interesting developments, in particular to evaluate the effectiveness of new drugs in both psychiatry and neurology. materials and methods the article is a critical analysis of the most recent data currently present in scientific literature on the subject; a qualitative synthesis of only the most significant articles has b...

Endocannabinoids primarily influence neuronal synaptic communication within the nervous system. To exert their function, endocannabinoids need to travel across the intercellular space. However, how hydrophobic endocannabinoids cross cell membranes and move extracellularly remains an unresolved problem. Here, we show that endocannabinoids are secreted through extracellular membrane vesicles prod...

Endocannabinoids and their receptor CB1 play key roles in brain function. Astrocytes express CB1Rs that are activated by endocannabinoids released by neurons. However, the consequences of the endocannabinoid-mediated neuron-astrocyte signaling on synaptic transmission are unknown. We show that endocannabinoids released by hippocampal pyramidal neurons increase the probability of transmitter rel...

BACKGROUND The discovery of the endocannabinoid system and of its role in the regulation of energy balance has significantly advanced our understanding of the physiopathological mechanisms leading to obesity and type 2 diabetes. New knowledge on the role of this system in humans has been acquired by measuring blood endocannabinoids. Here we explored endocannabinoids and related N-acylethanolami...

Cannabinoids, the main active components of marijuana, have been shown to exert different adverse effects on male reproduction both in vertebrates and invertebrates. The main effects of endocannabinoids, a particular group of endogenously produced cannabinoids, in sperm are the inhibition of motility, capacitation and acrosome reaction, all fundamental processes necessary for oocyte penetration...

Cannabinoids are the most commonly recognized herbal plant, having much medicinal importance from ancient times and plays an important role in Indian culture. Now a day’s cannabinoids used for many therapeutic purposes, under clinical trial by various institutions. In latest discovery within humans, it was found that we also have cannabinoids, receptors, enzymes our body, so is termed as endoca...

Endocannabinoids, which are typically released by principal cells in response to prolonged depolarization, act as retrograde messengers to inhibit synaptic transmission. A recent study shows that in a specific subtype of cortical interneuron, endocannabinoids released under similar circumstances can also act cell-autonomously. Here, endocannabinoids endow these neurons with a memory of their ow...
