Figure 3.
Pharmacological blockade of MAGL or glutamate transporter enabled the spread of SSE. A, Intracellular dialysis of BAPTA (20 mm) and GDP-βS (2 mm) abolished SSE in wild-type control slices (n = 9; ***p < 0.001). The panel was taken from Figure 2A for the purpose of comparison. B, Bath application of MAGL inhibitor JZL184 (0.3 µm) substantially extended SSE (n = 7–9; ***p < 0.001), and intracellular dialysis of BAPTA and GDP-βS attenuated SSE (n = 7–8; ***p < 0.001), and the remaining SSE was abolished by the CB1 receptor antagonist AM251 (2 µm; n = 8–9, ***p < 0.001). C, Bath application of glutamate transporter inhibitor TBOA (100 µm) extended SSE (n = 8–9; ***p < 0.001), and intracellular dialysis of BAPTA and GDP-βS did not significantly alter SSE (n = 8–9; ***p < 0.001). D, Summary of changes in EPSC amplitude under experimental conditions shown in A–C(n = 7–9; ***p < 0.001, n.s. p > 0.05).
