Here, the immune system adapts its response during an infection to improve its recognition of the pathogen. This improved response is then retained after the pathogen has been eliminated, in the form of an immunological memory, and allows the adaptive immune system to mount faster and stronger attacks each time this pathogen is encountered.

An immune response is a physiological reaction which occurs within an organism in the context of inflammation for the purpose of defending against exogenous factors. These include a wide variety of different toxins, viruses, intra- and extracellular bacteria, protozoa, helminths, and fungi which could cause serious problems to the health of the host organism if not cleared from the body.
In immunology, systemic inflammatory response syndrome (SIRS) is an inflammatory state affecting the whole body. [1] It is the body's response to an infectious or noninfectious insult . Although the definition of SIRS refers to it as an "inflammatory" response, it actually has pro- and anti-inflammatory components.
In immunology, autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues and other normal body constituents. [1] [2] Any disease resulting from this type of immune response is termed an "autoimmune disease".
The term inflammation is not a synonym for infection. Infection describes the interaction between the action of microbial invasion and the reaction of the body's inflammatory response—the two components are considered together in discussion of infection, and the word is used to imply a microbial invasive cause for the observed inflammatory ...
In addition, in case of infection, parts of some plants are treated as disposable and replaceable, in ways that few animals can. Walling off or discarding a part of a plant helps stop infection spread. [37] Most plant immune responses involve systemic chemical signals sent throughout a plant. Plants use PRRs to recognize conserved microbial ...

Cytokines are a normal part of the body's immune response to infection, but their sudden release in large quantities may cause multisystem organ failure and death. [ 1 ] Cytokine storms may be caused by infectious or non-infectious etiologies , especially viral respiratory infections such as H1N1 influenza , H5N1 influenza , SARS-CoV-1 , [ 2 ...
