WebMay 12, 2010 · These pools have been given a bewildering array of names, but this review proposes that each vesicle can be assigned to one of three pools: the readily releasable pool (RRP), the recycling pool and the reserve pool. 모든 synaptic vesicle은 biochemistry나 ultrastructure의 측면에서 유사하다. WebFurthermore, we demonstrated that the depolarization-induced increase in transmitter release is mediated by increases in readily releasable pool (RRP) size and release probability, which are attributable to CaM activation by LTCC-dependent elevation of presynaptic Ca 2+ levels.

WebMar 3, 2024 · Biphasic insulin secretion from pancreatic β-cells is explained by the existence of two different pools of insulin secretory granules, the readily releasable pool (RRP) that is ready to be secreted during the early phase, and the releasable pool (RP), which needs to be first recruited to the plasma membrane in order to be released during the ... WebThese readily releasable vesicles are often described as constituents of a readily releasable pool (RRP).
