Role of endogenous cannabinoids in synaptic signaling.
Research of cannabinoid actions was boosted in the 1990s by remarkable discoveries including identification of endogenous compounds with cannabimimetic activity (endocannabinoids) and the cloning of their molecular targets, the CB1 and CB2 receptors. Although the existence of an endogenous cannabinoid signaling system has been established for a decade, its physiological roles have just begun to...
متن کاملExcitement Reduces Inhibition via Endocannabinoids
Previous work has suggested a role for retrograde synaptic signaling via endogenous cannabinoids in regulating the inhibitory control of neuronal activity. In this issue of Neuron, Chevaleyre and Castillo provide evidence for another form of endocannabinoid-mediated depression of hippocampal inhibition, which is activity dependent and long lasting.
متن کاملEndogenous cannabinoids mediate long-term synaptic depression in the nucleus accumbens.
Do endocannabinoids (eCBs) participate in long-term synaptic plasticity in the brain? Using pharmacological approaches and genetically altered mice, we show that stimulation of prelimbic cortex afferents at naturally occurring frequencies causes a long-term depression of nucleus accumbens glutamatergic synapses mediated by eCB release and presynaptic CB1 receptors. Translation of glutamate syna...
متن کاملCannabinoids on the brain.
Cannabis has a long history of consumption both for recreational and medicinal uses. Recently there have been significant advances in our understanding of how cannabis and related compounds (cannabinoids) affect the brain and this review addresses the current state of knowledge of these effects. Cannabinoids act primarily via two types of receptor, CB1 and CB2, with CB1 receptors mediating most...
متن کاملP 148: The Role of Cannabinoids in Ischemia Stroke
Inflammation serves a protective function in controlling infections and promoting tissue repair, and can also cause damage to tissue and disease. Many types of cells involved in this process, expressing the components of the cannabinoid signaling system that can be controlled endogenously or pharmacologically. Cannabinoids inhibit neuroinflammation and the immune cells express the whole machi...
