1. The effect of guanosine on L-[2,3-3H]glutamate uptake was investigated in brain cortical slices under normal or oxygen–glucose deprivation (OGD) conditions. 2. In slices exposed to physiological conditions, guanosine (1–100 μM) stimulated glutamate uptake (up to 100%) in a concentration-dependent manner when a high (100 μM) but not a low (1 μM) concentration of glutamate was used. 3. In slices submitted to OGD, guanosine 1 and 100 μM also increased 100 μM glutamate uptake (38 and 70… CONTINUE READING
