dc.description.abstractIt has been shown in the study that glutamate transporters (EAAT) are capable to modulate GABA transports (GAT). Here we also report that DL-TBOA, a non-transportable glutamate uptake blocker, eliminates GAT-mediated GABA release, while D-aspartate, an EAAT substrate, does not block the latter. The strength or even the operating mode of GABA uptake/release could be influenced by the work of EAATs. Considering the interaction between EAATs and GATs we can conclude that ambient glutamate and GABA levels are mutually dependent. The EAAT-GAT crosstalk observed in this work is mediated by EAAT1 and GAT-2/3. Since both transporters are Na+ dependent and mainly glial, next we investigated the role of [Na+]i in astrocytic-mediated glutamate uptake. We tested whether [Na+]i changes affect paired-pulse plasticity of STCs recorded from cortical layer 2/3 astrocytes. We report that an elevation of [Na+]i induced either by using a high [Na+]i intrapipette solution or by application of GABA slows STCs kinetics and decrease paired-pulse facilitation (PPF) of STCs at short inter-stimulus intervals. Moreover, GAT inhibitors decrease PPF of STCs under control conditions, suggesting that endogenous GABA operating via GATs influences EAAT-mediated transporten_GB
