Figure 7. 3-oxa-PD1 increases inhibitory synaptic transmissions in spinal cord slices of CTCL mice.

Figure 7.

(A-B) Representative traces of spontaneous IPSCs (sIPSC) in lamina IIo neurons of naïve CB17 (A) and CTCL (B) mice. Traces 1 and 2 are enlarged in the bottom panels. (C-D) Quantification of sIPSC frequency in naïve and CTCL mice. Unpaired t-test, n = 16 neurons from 4 naïve mice and n = 20 neurons from 3 CTCL mice of both sexes. (E, F) Time course showing the effects of bath application of 3-oxa-PD1 (10 ng/ml, 3 min) on percentage changes of sIPSC frequency (E, n=13 neurons) and sEPSC amplitude (F, n=13 neurons). Arrows indicate before and after 3-oxa-PD1 perfusion. Note that 3-oxa-PD1 decreased the frequency but not amplitude of sEPSCs in spinal cord neurons of CTCL mice. Also note the effect of 3-oxa-PD1 can be washed out in 5 min. (G) sIPSC frequency in CTCL mice. Paired t-test, n = 13 neurons from 3 CTCL mice. (H) Cumulative probability of inter-event interval shows shorter interval after Oxa-PD1 application. Two-sample Kolmogorov-Smirnov test. (I) sEPSC amplitude. Paired t-test, n = 13 neurons from 3 CTCL mice. (J) Cumulative probability of amplitude. The data were analyzed at 1 min (before treatment) and 5 min (after treatment). Data are shown as mean ± SEM.
