Figure 3From: Differential regulation of muscarinic M1 receptors by orthosteric and allosteric ligandsTime course of receptor internalization as visualized by confocal microscopy. Translocation of cell surface receptors into intracellular vesicles was measured for carbachol (1 mM), NDMC (10 μM) and AC-260584 (10 μM). Images are from a representative experiment repeated 2-3 times with similar results.Back to article page
