Animation. This animation depicts three membrane trafficking routes in a mammalian neurosecretory cell, highlighting the changing Cl concentrations and pH values of the various endosomal subcompartments. Once you have clicked the "Play" button to start the animation, you can choose to highlight the pathway for receptor recycling to the plasma membrane, the lysosomal pathway, or the pathway for synaptic vesicle recycling (in neurons). Each compartment shown has a distinctive pH and [Cl], with values for pH indicated in blue and values for Cl indicated in orange. The intravesicular [Cl] in synaptic vesicles, large dense core vesicles, and lysosomes has not yet been determined. This animation was created by Julie White, under the scientific oversight of Criss Hartzell and Victor Faundez.
