Anandamide and NADA bi-directionally modulate presynaptic Ca<sup>2+</sup> level...
Köfalvi, A.; Pereira, M. F.; Rebola, N.; Rodrigues, R. J.; Oliveira, C. R.; Cunha, R. A.Inhibitory CB1 cannabinoid receptors and excitatory TRPV1 vanilloid receptors are abundant in the hippocampus. We tested if two known hybrid endocannabinoid/endovanilloid substances, N-arachidonoyl-dopamine (NADA) and anandamide (AEA), presynapticaly increased or decreased intracellular calcium level ([Ca2+]i) and GABA and glutamate release in the hippocampus. Resting and K+-evoked levels of [Ca2+]i and the rel...
Adenosine A2A receptors and metabotropic glutamate 5 receptors are co-localized...
Tebano, M. T.; Martire, A.; Rebola, N.; Pepponi, R.; Domenici, M. R.; Grò, M. C.; Schwarzschild, M. A.; Chen, J. F.; Cunha, R. A.; Popoli, P.Hippocampal metabotropic glutamate 5 receptors (mGlu5Rs) regulate both physiological and pathological responses to glutamate. Because mGlu5R activation enhances NMDA-mediated effects, and given the role played by NMDA receptors in synaptic plasticity and excitotoxicity, modulating mGlu5R may influence both the physiological and the pathological effects elicited by NMDA receptor stimulation. We evaluated whether...
