Figure 6. Zolpidem and THIP reveal changes of α1-δ subunit expression in altered KCC2 expression.
(a) Summary of the average percent increase in the sIPSC decay kinetics in KCC2 and KCC2 shRNA transfected neurons by application of Zolpidem (at DIV6–7 control n=6; KCC2 over n=9 *P<0.05; ANOVA; at DIV12–13 control n=9; KCC2 shRNA n=10; **P<0.01; ANOVA). (b) Representative whole-cell responses in KCC2 and KCC2 shRNA transfected neurons to applications of THIP (30 μM) and GABA (1 mM). (c) Summary of the average current density ITHIP/IGABA in KCC2 transfected neurons (control, grey bar n=22; KCC2 over, black bar n=22; ***P<0.001 ANOVA). (d) Summary of the average current density ITHIP/IGABA in KCC2 shRNA transfected neurons (control, grey bar n=12; KCC2 shRNA, white bar n=12; ***P<0.001 ANOVA). Data is presented as mean±s.e.m.
