|
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:0006955
|
immune response
|
Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. |
|
GO:0016068
|
type I hypersensitivity
|
An inflammatory response driven by antigen recognition by antibodies bound to Fc receptors on mast cells or basophils, occurring within minutes after exposure of a sensitized individual to the antigen, and leading to the release of a variety of inflammatory mediators such as histamines. |
|
GO:0006954
|
inflammatory response
|
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. |
|
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:0002526
|
acute inflammatory response
|
Inflammation which comprises a rapid, short-lived, relatively uniform response to acute injury or antigenic challenge and is characterized by accumulations of fluid, plasma proteins, and granulocytic leukocytes. An acute inflammatory response occurs within a matter of minutes or hours, and either resolves within a few days or becomes a chronic inflammatory response. |
|
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:0002438
|
acute inflammatory response to antigenic stimulus
|
An acute inflammatory response to an antigenic stimulus. An acute inflammatory response occurs within a matter of minutes or hours, and either resolves within a few days or becomes a chronic inflammatory response. |
|
GO:0002449
|
lymphocyte mediated immunity
|
Any process involved in the carrying out of an immune response by a lymphocyte. |
|
GO:0002437
|
inflammatory response to antigenic stimulus
|
An inflammatory response to an antigenic stimulus, which can be include any number of T cell or B cell epitopes. |
|
GO:0016064
|
immunoglobulin mediated immune response
|
An immune response mediated by immunoglobulins, whether cell-bound or in solution. |
|
GO:0002443
|
leukocyte mediated immunity
|
Any process involved in the carrying out of an immune response by a leukocyte. |
|
GO:0002524
|
hypersensitivity
|
An inflammatory response to an exogenous environmental antigen or an endogenous antigen initiated by the adaptive immune system. |
|
GO:0002250
|
adaptive immune response
|
An immune response based on directed amplification of specific receptors for antigen produced through a somatic diversification process, and allowing for enhanced response to subsequent exposures to the same antigen (immunological memory). |
|
GO:0002252
|
immune effector process
|
Any process of the immune system that can potentially contribute to an immune response. |
|
GO:0002460
|
adaptive immune response based on somatic recombination of immune receptors built from immunoglobulin superfamily domains
|
An immune response based on directed amplification of specific receptors for antigen produced through a somatic diversification process that includes somatic recombination of germline gene segments encoding immunoglobulin superfamily domains, and allowing for enhanced responses upon subsequent exposures to the same antigen (immunological memory). Recombined receptors for antigen encoded by immunoglobulin superfamily domains include T cell receptors and immunoglobulins (antibodies). An example of this is the adaptive immune response found in Mus musculus. |
|
GO:0019724
|
B cell mediated immunity
|
Any process involved with the carrying out of an immune response by a B cell, through, for instance, the production of antibodies or cytokines, or antigen presentation to T cells. |
