Fig. 7

Low-density hippocampal neurons were infected at 7 DIV with mCherry-tagged Scramble or ShPRRT2 lentivirus in combination with cof-S3E-mCherry or cof-S3A-mCherry. At 14 DIV, mEPSCs were recorded in whole-cell patch-clamp with holding potential of −70 mV. A Representative traces of mEPSCs from all phenotypes tested. B Analysis of mEPSCs. Amplitude, frequency, area, rise 10–90% and 80% decay of mEPSCs are expressed as mean ± SEM of n = number of cells (Scramble = 11, ShPRRT2 = 14, Scr+cof-S3E = 21, Sh+cofS3E = 20, Scr+cof-S3A = 8, Sh+cofS3A = 7 from 3 independent experiments). Amplitude (pA) mean ± SEM: Scramble = 16.90 ± 1.17, ShPRRT2 = 10.24 ± 0.69, Scr+cof-S3E = 18.02 ± 0.96, Sh+cofS3E = 10.30 ± 0.59, Scr+cof-S3A = 17.62 ± 1.65, Sh+cofS3A = 9.94 ± 0.68, p < 0.001 Scramble vs ShPRRT2, p < 0.001 Scr+cofS3E vs Sh+cof-S3E, p < 0.01 Scr+cofS3A vs Sh+cof-S3A; frequency (Hz): Scramble = 3.93 ± 0.72, ShPRRT2 = 1.24 ± 0.40, Scr+cof-S3E = 4.12 ± 0.64, Sh+cofS3E = 1.26 ± 0.25, Scr+cof-S3A = 3.36 ± 0.56, Sh+cofS3A = 1.11 ± 0.46, p < 0.05 Scramble vs ShPRRT2, p < 0.001 Scr+cofS3E vs Sh+cof-S3E, p < 0.05 Scr+cofS3A vs Sh+cof-S3A; area (pA*ms): Scramble = 63.28 ± 3.72, ShPRRT2 = 34.24 ± 3.13, Scr+cof-S3E = 52.27 ± 3.65, Sh+cofS3E = 31.44 ± 3.14, Scr+cof-S3A = 53.37 ± 5.44, Sh+cofS3A = 27.75 ± 2.75; p < 0.001 Scramble vs ShPRRT2, p < 0.001 Scr+cofS3E vs Sh+cof-S3E, p < 0.05 Scr+cofS3A vs Sh+cof-S3A; rise 10–90 (ms): Scramble = 1.28 ± 0.08, ShPRRT2 = 1.31 ± 0.08, Scr+cof-S3E = 0.94 ± 0.05, Sh+cofS3E = 1.26 ± 0.11, Scr+cof-S3A = 0.96 ± 0.07, Sh+cofS3A = 1.22 ± 0.09; 80% decay (ms): Scramble = 5.13 ± 0.26, ShPRRT2 = 4.18 ± 0.28, Scr+cof-S3E = 3.96 ± 0.16, Sh+cofS3E = 3.78 ± 0.37, Scr+cof-S3A = 4.47 ± 0.55, Sh+cofS3A = 3.34 ± 0.27. Statistical analysis was conducted with Student’s t-test (Scramble vs ShPRRT2 couples); *p < 0.05, **p < 0.01, ***p < 0.001.
