From the abstract
The potassium-chloride cotransporter 2 (KCC2) is a neuron-specific transporter essential for maintaining low intracellular chloride levels. By extruding chloride ions, KCC2 ensures that activation of GABA A receptors produces hyperpolarizing inhibitory responses rather than depolarizing responses.
