Microelectrode arrays of diamond-insulated graphitic channels for real time detection of exocytotic events from cultured chromaffin cells and slices of adrenal glands [PDF]
, 2016 A microstructured graphitic 4x4 multielectrode array was embedded in a single crystal diamond substrate (4x4 {uG-SCD MEA) for real-time monitoring of exocytotic events from cultured chromaffin cells and adrenal slices.

Cold Spring Harbor Perspectives in Biology, 2017 Polarized exocytosis is generally considered as the multistep vesicular trafficking process in which membrane-bounded carriers are transported from the Golgi or endosomal compartments to specific sites of the plasma membrane.

Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]
, 1987 Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

PLoS ONE, 2014 Impairment in beta-cell exocytosis is associated with reduced insulin secretion and diabetes. Here we aimed to investigate the dynamics of Ca2+-dependent insulin exocytosis with respect to pool depletion and Ca2+-current inactivation.

Lytic granule exocytosis at immune synapses: lessons from neuronal synapses
Frontiers in Immunology, 2023 Regulated exocytosis is a central mechanism of cellular communication. It is not only the basis for neurotransmission and hormone release, but also plays an important role in the immune system for the release of cytokines and cytotoxic molecules.

Exocytosis from permeabilized bovine adrenal chromaffin cells is differently modulated by guanosine 5'-[gamma-thio]triphosphate and guanosine 5'-[beta gamma-imido]triphosphate [PDF]
, 1992 1. In bovine adrenal chromaffin cells made permeable either to molecules less than or equal to 3 kDa with alphatoxin or to proteins less than or equal to 150 kDa with streptolysin O, the GTP analogues guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)

Animal Cells and Systems, 2020 Bafilomycin A1, a vacuolar H+-ATPase inhibitor, and botulinum toxin B and tetanus toxin, both vesicle fusion inhibitors, are widely known exocytosis blockers that have been used to inhibit the presynaptic release of neurotransmitters.

ARF6–JIP3/4 regulate endosomal tubules for MT1-MMP exocytosis in cancer invasion
Journal of Cell Biology, 2015 Interaction of plasma membrane ARF6 with JIP3/JIP4 effectors on MT1-MMP endosomes coordinates dynactin–dynein and kinesin-1 activity in a tug-of-war mechanism for endosome tubulation and MT1-MMP exocytosis to promote breast cancer cell invasion.

Exploring the functional domain and the target of the tetanus toxin light chain in neurohypophysial terminals [PDF]
, 1994 The tetanus toxin light chain blocks calcium induced vasopressin release from neurohypophysial nerve terminals. Here we show that histidine residue 233 within the putative zinc binding motif of the tetanus toxin light chain is essential for the ...

Tracing the STING exocytosis pathway during herpes viruses infection
mBioThe STimulator of INterferon Genes (STING) constitutes a major DNA-sensing pathway that restricts HSV-1 infection in different models by activating type I interferon and pro-inflammatory responses.
