WebAug 15, 2000 · Increased Ca(2+) signals coupled with reduced release suggest a direct function of CSP in exocytosis downstream from Ca(2+) entry. Because the reduction of evoked release in csp mutants is counteracted by increased Ca(2+) levels, we suggest that CSP primarily increases the Ca(2+) sensitivity of the exocytotic machinery. WebJan 9, 2013 · Drugs of abuse hijack brain-reward circuitry during the addiction process by augmenting action potential-dependent phasic dopamine release events associated with learning and goal-directed behavior. One prominent exception to this notion would appear to be amphetamine (AMPH) and related analogs, which are proposed instead to disrupt …

Requirement of Inositol Pyrophosphates for Full Exocytotic

WebMay 7, 2012 · In plants, exocytotic processes are mediated by v-SNAREs belonging to the VAMP72 (vesicle-associated membrane protein) family ( 26, 27 ). Previously, it has been shown that specific VAMP72 genes have been recruited in the Arabidopsis interaction with biotrophic fungi ( 27 ). WebOct 13, 1998 · It was suggested that the images observed during release were exocytotic, whereas those observed during the rest period were endocytotic. This led to the proposal that vesicles do not collapse into the plasma membrane after exocytosis but, rather, immediately pinch back off (kiss and run hypothesis). Our observations on active zone … black blue rea cd pleyer

A finite-element model of granular serotonin exocytosis

WebMar 1, 2024 · Understanding serotonin release from platelet granules can provide valuable fundamental information about the exocytotic process and help elucidate potential abnormalities of diseased platelets. Experimentally, carbon-fiber microelectrochemistry has been utilized to characterize the dynamic behavior of serotonin secretion from individual … WebAug 7, 2007 · Exocytotic events at the ventral plasma membrane can be visualized by total internal reflection fluorescence microscopy (TIRFM): Because of the fact that the evanescent wave displays an exponential decay, vesicles approaching the coverslip and fusing with the membrane display a sharp increase in their fluorescence intensity … Webex·o·cy·to·sis ( ek'sō-sī-to'sis ), 1.
