Astrocytes activated by different signals modulate GABAergic transmission. Summary of the astrocytic modulation of GABAergic transmission in response to different signals (see §3). TRPA1, transient receptor potential A1; GAT3, GABA transporter type 3; EAATs, excitatory amino acid transporters; Best-1, bestrophin-1; SOCs, slow outward currents; PAR1, protease-activated receptor type-1.
