WebMay 19, 2006 · Moreover, blockade of K +-channels by 4-aminopyridine (4-AP) strongly enhanced the electrically evoked release of [3 H]creatine as well as that of endogenous creatine. These in vitro data indicate that creatine is not only synthesized and taken up by central neurons, but also released in an action-potential dependent (exocytotic) manner ... WebFeb 22, 2024 · An important observation is that extracellular molecules can be introduced to cells during the partial exocytotic release process. This nonendocytic transport process appears to be a general route of entry that might be exploited pharmacologically.

WebCombined with these two methods, we quantified the catecholamines stored in vesicles and compared them to exocytotic release, calculating the fraction of catecholamine released in each event. In addition, the high temporal resolution of amperometry allows the dynamics of vesicle release and vesicle opening to be measured. WebNov 11, 2024 · Exocytotic release was enhanced for many of the stimulus sequences. The vesicular catecholamine content decreased with short-interval repetitive stimulations. Here, 161 000 molecules were detected before stimulation by IVIEC, while only 120 000 molecules were detected after the sixth stimulation. WebAug 7, 2024 · The fraction of release is calculated by the number of molecules released during exocytosis over the total number of molecules stored in single vesicles. On average, 80±2.4 % of 5-HT is released, indicating vesicles in BON cells release a large fraction of 5-HT during individual exocytosis events. ge india head
