Mapping organelle motion reveals a vesicular conveyor belt spatially replenishing secretory vesicles in stimulated chromaffin cells. [PDF]
PLoS ONE, 2014 How neurosecretory cells spatially adjust their secretory vesicle pools to replenish those that have fused and released their hormonal content is currently unknown.

Actin and Myosin in Non-Neuronal Exocytosis
Cells, 2020 Cellular secretion depends on exocytosis of secretory vesicles and discharge of vesicle contents. Actin and myosin are essential for pre-fusion and post-fusion stages of exocytosis.

Evidence for the existence of secretory granule (dense-core vesicle)-based inositol 1,4,5-trisphosphate-dependent Ca2+ signaling system in astrocytes. [PDF]
PLoS ONE, 2010 BACKGROUND: The gliotransmitters released from astrocytes are deemed to play key roles in the glial cell-neuron communication for normal function of the brain. The gliotransmitters, such as glutamate, ATP, D-serine, neuropeptide Y, are stored in vesicles

Substantial Evidence for Auxin Secretory Vesicles [PDF]
Plant Physiology, 2018 Dear Editor, In their letter, [Robinson et al., 2018][1] question our recent report on auxin clustered within cells of Arabidopsis root apices. They claim that small molecules such as IAA cannot be visualized using the immunogold EM techniques.

Roles of the TRAPP-II Complex and the Exocyst in Membrane Deposition during Fission Yeast Cytokinesis. [PDF]
PLoS Biology, 2016 The cleavage-furrow tip adjacent to the actomyosin contractile ring is believed to be the predominant site for plasma-membrane insertion through exocyst-tethered vesicles during cytokinesis.

Measuring Intracellular Vesicle Density and Dispersion Using Fluorescence Microscopy and ImageJ/FIJI
Bio-Protocol, 2020 Cell signalling, cell secretion, and plasma membrane repair are processes that critically rely on intracellular vesicles, important components of the endocytic and secretory pathways.

Mechanistic Insights into Membrane Protein Clustering Revealed by Visualizing EGFR Secretion
Research, 2022 Most plasmalemmal proteins are organized into clusters to modulate various cellular functions. However, the machineries that regulate protein clustering remain largely unclear.

Mesenchymal Stem Cells Exhibit Regulated Exocytosis in Response to Chemerin and IGF. [PDF]
PLoS ONE, 2015 Mesenchymal stem cells (MSCs) play important roles in tissue repair and cancer progression. Our recent work suggests that some mesenchymal cells, notably myofibroblasts exhibit regulated exocytosis resembling that seen in neuroendocrine cells.

Journal of Marine Science and Engineering, 2022 To continue the investigation on the digestive system of polyplacophoran molluscs, a histological and ultrastructural study of the oesophagus, stomach and intestine of Chaetopleura angulata and Acanthochitona fascicularis was carried out. Stomach content
