Differential glutamatergic and GABAergic contributions to the tetrad effects of Δ9-tetrahydrocannabinol revealed by cell-type-specific reconstitution…
2020
Δ9-tetrahydrocannabinol (THC), the major psychoactive ingredient of Cannabis sativa, exerts its actions through the endocannabinoid system by stimulation of the cannabinoid type 1 (CB1) receptor. The widespread distribution of this receptor in different neuronal cell types and the plethora of functions that is modulated by the endocannabinoid system explain the versatility of the effects of THC. However, the cell types involved in the different THC effects are still not fully known. Conditional CB1 receptor knock-out mice were previously used to identify CB1 receptor subpopulations that are "necessary" for the tetrad effects of a high dose of THC: hypothermia, hypolocomotion, catalepsy and …
Cell type‐specific genetic reconstitution of CB1 receptor subsets to assess their role in exploratory behaviour, sociability, and memory
2021
Several studies support the notion that exploratory behaviour depends on the functionality of the cannabinoid type 1 (CB1) receptor in a cell type-specific manner. Mice lacking the CB1 receptor in forebrain GABAergic or dorsal telencephalic glutamatergic neurons have served as essential tools revealing the necessary CB1 receptor functions in these two neuronal populations. However, whether these specific CB1 receptor populations are also sufficient within the endocannabinoid system for wild-type-like exploratory behaviour has remained unknown. To evaluate cell-type-specific sufficiency of CB1 receptor signalling exclusively in dorsal telencephalic glutamatergic neurons (Glu-CB1-RS) or in fo…
