GO:0006952
|
defense response
|
Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack. |
GO:0006950
|
response to stress
|
Any process that results in 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 disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation). |
GO:0009626
|
plant-type hypersensitive response
|
The rapid, localized death of plant cells in response to invasion by a pathogen. |
GO:0006955
|
immune response
|
Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. |
GO:0051716
|
cellular response to stimulus
|
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus by a cell and ends with a change in state or activity or the cell. |
GO:0008219
|
cell death
|
Any biological process that results in permanent cessation of all vital functions of a cell. A cell should be considered dead when any one of the following molecular or morphological criteria is met: (1) the cell has lost the integrity of its plasma membrane; (2) the cell, including its nucleus, has undergone complete fragmentation into discrete bodies (frequently referred to as "apoptotic bodies"); and/or (3) its corpse (or its fragments) have been engulfed by an adjacent cell in vivo. |
GO:0045087
|
innate immune response
|
Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
GO:0009987
|
cellular process
|
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. |
GO:0044763
|
single-organism cellular process
|
Any process that is carried out at the cellular level, occurring within a single organism. |
GO:0044699
|
single-organism process
|
A biological process that involves only one organism. |
GO:0008150
|
biological_process
|
Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end. |
GO:0050896
|
response to stimulus
|
Any process that results in 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. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism. |
GO:0033554
|
cellular response to stress
|
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating the organism is under stress. The stress is usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation). |
GO:0002376
|
immune system process
|
Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats. |
GO:0016265
|
death
|
A permanent cessation of all vital functions: the end of life; can be applied to a whole organism or to a part of an organism. |
GO:0012501
|
programmed cell death
|
A process which begins when a cell receives an internal or external signal and activates a series of biochemical events (signaling pathway). The process ends with the death of the cell. |
GO:0034050
|
host programmed cell death induced by symbiont
|
Cell death in a host resulting from activation of host endogenous cellular processes after direct or indirect interaction with a symbiont (defined as the smaller of two, or more, organisms engaged in symbiosis, a close interaction encompassing mutualism through parasitism). An example of direct interaction is contact with penetrating hyphae of a fungus; an example of indirect interaction is encountering symbiont-secreted molecules. |
