WebJan 20, 2016 · Photolytic uncaging of p-hydroxyphenacyl (pHP) GABA demonstrates backpropagation of GABA A R-mediated depolarizations from MNTB axon terminals to the soma, some hundreds of microns away. These somatic depolarizations enhanced somatic excitability by increasing the probability of action potential generation. GABA spillover … WebJul 1, 2024 · Second, the light required for photo-uncaging should be longer than 300 ... Hoffmann and Kazmaier proposed a photolytic linearization strategy in which the N- and C-termini of a peptide were linked by an NB-type of the photosensitive linker and cyclized through RCM and photolysis linearizes the peptide (Scheme 2) [13]. This strategy permits ...
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 ... 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 …
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 … WebPrevious attempts of modifying the oNB group to improve the light-harvesting efficiency have usually led to decreased uncaging quantum yields, so the overall photolytic …
