exocytosis

noun

Biology
  • [mass noun] A process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.

    • ‘Membrane fusion is a key event in many essential cell processes, such as exocytosis, endocytosis, membrane recycling, protein sorting and transport, fertilization, and cell division.’
    • ‘Synaptic nerve terminals and neuroendocrine cells rely on continuous vesicle cycling to support sustained exocytosis and transmitter release.’
    • ‘In the studies cited, only the intensity of fluorescence was used to observe the metabolism, exocytosis and phagocytosis of cells.’
    • ‘Urea and lysozyme secretion were dose dependent in all groups, suggesting that serous cell exocytosis was one source of urea after neural stimulation.’
    • ‘Planar-supported membranes provide an interesting and very useful new approach to study the complex molecular machinery of exocytosis and membrane fusion.’
