Figure 5. Redox regulation does not contribute to increased NMDAR synaptic function induced by upregulation of SR expression. (A) Time course of changes in the slope of the NMDAR-fEPSP obtained from mPFC slices 10 min before and up to 60 min after bath application of the reducing agent, DTT (0.5 mM; solid line) for slices obtained from LV-SR (filled circle, n = 8/4 slices/animals) and LV-GFP (control, open circle, n = 8/4 slices/animals) animals. (B) Scatter gram illustrating individual DTT-induced potentiation along with mean percentage increase (black solid line) in the slope of NMDAR-fEPSP in slices obtained from LV-SR (filled circle) and LV-GFP (open circle) animals. (C) Input-output curve of NMDAR-fEPSP slope in slices obtained from LV-GFP (open circle) and LV-SR (filled circle) rats 60 min following bath application of DTT (0.5 mm, solid line), across increasing stimulation intensities. *indicates a significant treatment difference at higher stimulation intensities (16–40V).
