It is currently thought that immune responses are initiated by pathogen-associated molecular patterns or by tissue-derived danger/alarm signals. Here, we propose that these two groups of molecules might not be mutually exclusive. Many of them might be part of an evolutionarily ancient alert system in which the hydrophobic portions of biological molecules act, when exposed, as universal damage-associated molecular patterns to initiate repair, remodelling and immunity. 

Damage-Associated Molecular Pattern-Triggered Immunity in Plants

This review presents an extensive overview on the current understanding of damage-associated molecular patterns in plant immune system and explains how these processes integrate together to determine intricate mechanisms of DAMP-triggered immunity in plants.

Five classes of cell stress/tissue injury-induced DAMPs are identified that are sensed by various recognition receptor-bearing cells of the innate immune system, thereby mounting inflammation, promoting apoptosis and shaping adaptive immune responses.

Danger-Associated Molecular Patterns Derived From the Extracellular Matrix Provide Temporal Control of Innate Immunity

The current knowledge of the interplay between ECM-derived DAMPs and the innate immune signaling pathways that are activated to provide temporal control of innate immunity is discussed.

The grateful dead: damage‐associated molecular pattern molecules and reduction/oxidation regulate immunity

It is speculated that their destruction through oxidative mechanisms normally exerted by myeloid cells, such as neutrophils and eosinophils, or their persistence in the setting of pathologic extracellular reducing environments, maintained by exuberant necrotic cell death and/or oxidoreductases, represent important molecular means enabling chronic inflammatory states.

DAMPs, PAMPs and alarmins: all we need to know about danger

The term “alarmin” is proposed to categorize such endogenous molecules that signal tissue and cell damage, and can be considered subgroups of a larger set, the damage‐associated molecular patterns (DAMPs).

The interplay between pathogen‐associated and danger‐associated molecular patterns: an inflammatory code in cancer?

Findings are reviewed that support the notion of a PAMP–DAMP‐based inflammatory code, with emphasis on cancer immunology and immunotherapy.
