The chronic effects of glycine transporter 1 and 2 inhibitors (sarcosine and ALX-1393, respectively) on miniature inhibitory postsynaptic currents were studied in cultured spinal neurons. We found that sarcosine increased the frequency of overall miniature inhibitory postsynaptic currents without affecting the ratio of glycinergic, mixed and GABAergic miniature inhibitory postsynaptic currents,...
