WebMar 1, 2024 · The readily releasable pool comprises few vesicles that are docked at the plasma membrane and primed for immediate fusion upon stimulation. The recycling pool generally comprises 10%–20% of all vesicles in the terminal and is recruited after the readily releasable pool has been depleted during moderate physiological stimulation. The sum of ... WebJan 5, 2016 · Here, we investigate the ultrastructural and functional effects of Arf6 silencing in hippocampal synapses and reveal an unexpected presynaptic role for this small GTPase in determining the size of the readily releasable pool of SVs and in promoting direct versus endosomal recycling of SVs.
