Journal of Neuroscience Methods, 1996
Immunoelectrodes have been developed which can be used to detect minute amounts of somatostatin. They were made with electrochemically treated glassy carbon fibres coated with anti-somatostatin antibodies. Calibration and various controls were carried out to ensure that the immunoelectrodes responded specifically to the presence of femtomolar ...

Veratridine triggers exocytosis in Paramecium cells by activating somatic Ca channels
Journal of Membrane Biology, 1994Paramecium tetraurelia wild-type (7S) cells respond to 2.5 mM veratridine by immediate trichocyst exocytosis, provided [Ca2+]o (extracellular Ca2+ concentration) is between about 10(-4) to 10(-3) M as in the culture medium. Exocytosis was analyzed by light scattering, light and electron microscopy following quenched-flow/freeze-fracture analysis ...

International Journal of Molecular Sciences, 2022 The soma, dendrites and axon of neurons may display calcium-dependent release of transmitters and peptides. Such release is named extrasynaptic for occurring in absence of synaptic structures.

PKA-dependent phosphorylation of LIMK1 and Cofilin is essential for mouse sperm acrosomal exocytosis [PDF]
Developmental Biology, 2015 Mammalian sperm must acquire their fertilizing ability after a series of biochemical modifications in the female reproductive tract collectively called capacitation to undergo acrosomal exocytosis, a process that is essential for fertilization.

The molecular basis underlying the binding of spermatozoa to their homologous eggs and the subsequent induction of acrosomal exocytosis remain a major unresolved issue in mammalian fertilization. Novel cell adhesion systems are now being explored to advance this research.

<p>The Priming Factor CAPS, Mediates Somatic Exocytosis of Serotonin</p>
The role of the vesicle priming factor CAPS (calcium-dependent activator protein for secretion) in somatic exocytosis was studied in the large serotonergic Retzius neuron of the leech. Increased electrical activity prompts Retzius neurons to release serotonin en masse from somatic dense core vesicles (DCVs). This exocytosis is evoked by calcium releaseJose Arturo Laguna +4 more
