Readily releasable pool
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. Results WebBecause an empty readily releasable pool refills with a time constant of about 5 seconds 1,2,3, the rate at which a vesicle docks and primes must be 0.2 per second or less. RESULTS.

Despite the importance of MVR in information transmission and processing between neurons, we lack an understanding of its role in brain regions such as the neocortex, which is the seat ...
WebThe readily releasable pool (RRP) of vesicles in rods and cones measured using glutamate transporter anion currents (IA(glu)) was also halved. We also studied the release from cones by stimulating ... Webthe readily releasable pool provides a possible cell biological mechanism for this form of long term synaptic plasticity in culture.

WebIn virtually every mature neuronal preparation, a class of “release-ready” vesicles has been defined and named the readily releasable pool (RRP). In hippocampal terminals, only a … Synaptic vesicles are relatively simple because only a limited number of proteins fit into a sphere of 40 nm diameter. Purified vesicles have a protein:phospholipid ratio of 1:3 with a lipid composition of 40% phosphatidylcholine, 32% phosphatidylethanolamine, 12% phosphatidylserine, 5% phosphatidylinositol, and 10% cholesterol.
WebAug 21, 2015 · However, the specific contribution that retrieved vesicles make to future transmission events remains unclear. Here we exploit fluorescence and time-stamped electron microscopy to track the functional and positional fate of vesicles endocytosed after readily releasable pool (RRP) stimulation in rat hippocampal synapses.
WebMar 20, 2013 · We conclude that newly endocytosed vesicles do not immediately traffic into readily releasable pool via a rapid, local recycling. Instead, they undergo a use-dependent pathway into a ‘readily priming pool’ and become readily releasable subsequently.
