Figure 7From: Modulation of transient receptor potential vanilloid 4-mediated membrane currents and synaptic transmission by protein kinase C Enhancement of 4α-PDD-induced increase in synaptic transmission by PDBu in cultured hippocampal neurons. A. Application of 4α-PDD (10 μM) increases the frequency of mEPSCs, which is further potentiated by PDBu. The synaptic events are shown at a higher time resolution below. B. Cumulative probability plot shows a decrease in inter-event interval. C. The increase in frequency is not accompanied by a change in the amplitude. D. Summary graph showing 4α-PDD induces an increase in mEPSC frequency and this action is enhanced by PDBu (n = 7). The asterisk (*) represents P < 0.05 as compared to control; (**) represents P < 0.05 as compared to 4α-PDD group.Back to article page
