"The regulation of the levels, transport, and metabolism of calcium ions within a cell or between a cell and its external environment [goid 6874] [pmid 10713092] [evidence TAS]; 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 [goid 6887] [pmid 10734056] [evidence TAS]; Any process involved in the controlled movement of a cell [goid 6928] [pmid 9558100] [evidence TAS]; The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis) [goid 6935] [pmid 10713092] [evidence TAS]; The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages [goid 6954] [pmid 10415069] [evidence TAS]; Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat [goid 6955] [pmid 10713092] [evidence TAS]; A defense response that is mediated by cells [goid 6968] [pmid 10640778] [evidence TAS]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals [goid 6979] [pmid 10713092] [evidence TAS]; The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules [goid 7155] [pmid 10910894] [evidence TAS]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [pmid 10770925] [evidence TAS]; Any process that mediates the transfer of information from one cell to another [goid 7267] [pmid 10734056] [evidence TAS]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus [goid 9615] [pmid 10640778] [evidence TAS]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus [goid 9615] [pmid 10583963] [evidence TAS]; Any process that stops, prevents or reduces the frequency, rate or extent of viral genome replication [goid 45071] [pmid 10490959] [evidence IDA]"
