WebMay 11, 2024 · By using either photolytic uncaging of intracellular Ca 2+ (Figure 4—figure supplement 1) or Ca 2+ infusion (Figure 4), we have observed opposite effects if the curvature-mediating lipid components were applied intracellularly and found, in contrast to Zhang and Jackson, only a slight increase in the sustained rate of secretion with LPC … WebFeb 22, 2024 · Photolytic uncaging of biologically-active molecules within cells is usually a powerful technique. IP3, ATP, cAMP, and other molecules. The list of caged compounds is …

WebFeb 1, 2006 · Similar to photolytic uncaging experiments, intracellular Ca 2+ concentrations could be elevated to produce a whole cell Ca 2+ rise, but without the requirement for caged Ca 2+. Irradiation of subcellular volumes in the soma or in PC12 neurites generated a relatively slow calcium rise (speed ∼20 µm/s). Less frequently, a fast calcium rise ... WebMay 1, 2007 · Ca(2+) rises evoked by photolytic uncaging of IP(3) showed the same distribution, suggesting that IP(3)-sensitive Ca(2+) stores are preferentially located in the soma and proximal dendrites. This distribution of metabotropic-mediated store release suggests that the neuromodulatory role of metabotropic receptor stimulation in BLA … circuit breaker westinghouse

The current trace is the average … WebJul 1, 2016 · In acute slices from C57BL/6 mice, we find that co-activation of presynaptic GABA receptors by photolytic uncaging of RuBi-GABA has a biphasic effect on EPSC amplitudes recorded from stellate cells. Synchronous and asynchronous EPSCs evoked within ∼100 ms of GABA uncaging were increased, while EPSCs evoked ∼300-600 ms … WebEquipment used: Photomanipulation system UGA-42 Firefly ( UGA-42 Firefly) with diode single line laser DL-405.
