Modulation of Seizures and Synaptic Plasticity by Adenosinergic Receptors in an Experimental Model of Temporal Lobe Epilepsy Induced by Pilocarpine in Rats

Abstract

The present data show that adenosine released during pilocarpine-induced SE via A1-receptor stimulation can exhibit neuroprotective and anticonvulsant roles. Similar effects could also be inferred with A2a and A3 adenosinergic agents, but further experiments are necessary to confirm their roles. Ecto-5 -nucleotidase activity during silent and chronic phases might have a role in blocking spontaneous seizures by production of inhibitory neuromodulator adenosine, besides taking part in the mechanism that controls sprouting.
