Figure 4. Stimulation of inward NCX1 current by carbachol, GTPγS, and latrunculin in parallel with an increase of capacitance.

Figure 4

Right panels, composite results for peak inward current and membrane capacitance. A, effect of carbachol (0.2 mm) in a BHK cell expressing NCX1 with transient expression of M1 receptors. B, effects of carbachol (0.2 mm) in CHO cells expressing M1 receptors with transient NCX1 expression. C, stimulation of inward exchange current by cytoplasm perfusion of GTPγS (0.3 mm) in the presence of AMP-PNP (2 mm). D, stimulation of inward exchange current by cytoplasm perfusion of latrunculin (0.8 μm) in the presence of AMP-PNP (2 mm).
