Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell. This is the process whereby most molecules are secreted from eukaryotic cells. Fusion of intracellular membrane-bounded vesicles with the pre-synaptic membrane of the neuronal cell resulting in release of neurotransmitter into the synaptic cleft. The controlled release of a substance by a cell, a group of cells, or a tissue. The initial attachment of a vesicle membrane to a target membrane, mediated by proteins protruding from the membrane of the vesicle and the target membrane, during exocytosis. A process of exocytosis found in all eukaryotic cells, in which transport vesicles destined for the plasma membrane leave the trans-Golgi network in a steady stream. Upon exocytosis, the membrane proteins and lipids in these vesicles provide new components for the plasma membrane, and the soluble proteins inside the vesicles are released into the extracellular space. Any process that stops, prevents or reduces the frequency, rate or extent of exocytosis. A process of exocytosis in which soluble proteins and other substances are initially stored in secretory vesicles for later release. It is found mainly in cells that are specialized for secreting products such as hormones, neurotransmitters, or digestive enzymes rapidly on demand. Any process that activates or increases the frequency, rate or extent of exocytosis. The release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell, requiring the presence of calcium ions. Any process that modulates the frequency, rate or extent of exocytosis. The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet. The directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells, or within a multicellular organism by means of some external agent such as a transporter or pore. The directed movement of a substance or cellular entity, such as a protein complex or organelle, to a specific location within, or in the membrane of, a cell. The directed movement of substances into, out of or within a cell by a cellular process that begins with the formation of membrane-bounded vesicles in which the transported substances are enclosed or located in the vesicle membrane. Vesicles are then targeted to, and fuse with, an acceptor membrane. The controlled release of a substance by a cell.
