Ca2+/Na+ influx is downregulated by NO application in nNOS−/− BG. (a–d) Images from a–d represent calcium (red) and sodium (green) responses at baseline and 3 min after d‐aspartate application (scale bar represents 100 μm). The representative time course of Ca2+/Na+ influx in response to application of d‐aspartate, denoted by the red arrow. The black line represents the Ca2+/Na+ influx of nNOS−/− BGs without a pretreatment (CON), while the orange line represents either nNOS−/− BGs pre‐treated with SNAP (a), SNAP+PKGi (b), UCPH (c), or NCXi (d). Black, dashed line represents baseline Ca2+/Na+ conductance. (e) Bar graph represents the area under the curve (AUC) for each pretreatment visualized in a–d after 5 min of d‐aspartate treatment. N = 3 experimental replicates. CON n = 23 cells, SNAP n = 20 cells, SNAP+PKGi
n = 26 cells, UCPH n = 25 cells, NCXi
n = 25 cells. F(4, 130) = 4.723; p = .0014
