This simple concept hides numerous implications to homeostasis, development and disease, which are here explained. Not only are all basic elements on DAMPs presented, but also comprehensive knowledge on immunology into which DAMPs biology is seamlessly interwoven.

B-cellsreceptorn är en PRR som kan känna igen PAMPs och DAMPs direkt; kan vara T-oberoende typ I eller II men B-cellen kan även fagocytera antigen och 

ALARMINS. Alarmins are the equivalent of PAMPs but are endogenous molecules. DAMPs such as calprotectin (S100A8/9) have an established clinical role as a biomarker in IBD. In this review, we use IBD as an archetypal common chronic inflammatory disease to focus on the conceptual and evidential importance of DAMPs in pathogenesis and why DAMPs represent an entirely new class of targets for clinical translation.

DAMPs bind specific receptors to activate inflammation and start a highly optimized sequence of immune cell recruitment of neutrophils and monocytes to initiate effective tissue repair. When DAMPs are cleared, the recruited leukocytes change from a proinflammatory to a reparative program, a switch that is locally supervised by invariant natural killer T cells. However, not all DAMPs are located intracellularly, they can also be generated by proteases that degrade extracellular matrix and thereby generate DAMPs like hyaluronic acid, 45 fibrinogen, 29 and fibronectin 30 (Table 1). Here, we give an overview of DAMPs that have been associated with nociceptive signaling, with a specific emphasis on HMGB1. This mini-review is focused on plant DAMPs, including the recently discovered Arabidopsis HMGB3, which is the counterpart of the prototypic animal DAMP HMGB1. The plant DAMPs will be presented in the context of plant MAMPs and NAMPs, as well as animal DAMPs. DAMPs, their receptors and downstream transduction mechanisms are often conserved within a kingdom or, due to convergent evolution, are similar across the kingdoms of life.

Examples include heat-shock proteins and altered membrane phospholipids. Damage-associated molecular patterns (DAMPs), also known as alarmins, are molecules released by stressed cells undergoing necrosis that act as endogenous danger signals to promote and exacerbate the inflammatory response. Danger-associated molecular patterns (DAMPs) that are released by injured, threatened, or dead cells, or that originate from the extracellular matrix, influence the immune system. At the end of the meeting, Joost Oppenheim proposed the term “alarmin” to differentiate the endogenous molecules that signal tissue and cell damage.

There is a critical need to expand the audience and interest in DAMPs and Alarmins across the basic sciences and clinical immunology. Building on the success of the first two meetings, we will explore the important areas of generation of DAMPs and Alarmins, the host response, and their critical role in cell death, tissue remodeling, and disease.

Due to its involvement in autoimmune diseases, chronic inflammatory diseases, and allergic diseases, as well as plant resistance to predators, initiation of innate immune responses by DAMPs is currently a Immune responses are initiated and perpetuated by molecules derived from microorganisms pathogen-associated molecular-pattern molecules or from the damage or death of host cells [damage-associated molecular-pattern (DAMP) molecules]. Many DAMPs are nuclear or cytosolic proteins with defined intracellular function that, when released outside the cell following tissue injury, move from a British Society for Immunology. 34 Red Lion Square, London WC1R 4SG.

At the end of the meeting, Joost Oppenheim proposed the term “alarmin” to differentiate the endogenous molecules that signal tissue and cell damage. Together, alarmins and PAMPs therefore constitute the larger family of damage‐associated molecular patterns, or DAMPs.
