It has long been known that the immune system initiates precise immune response through distinguishing self from non-self. In 1989, Charles Janeway proposed the concept of “pattern recognition,” which mediates specific recognition of conserved molecules derived from pathogens, called pathogen-associated molecular patterns (PAMPs). 1 PAMPs are recognized by pattern recognition receptors ...
However, the question is whether in between DAMPs and PAMPs, which one induces a stronger inflammatory response or is there any differential response in terms of the effect on ongoing various pathologies and strength? ... Liu et al. in a meta-analysis reported no significant differences in the accuracy of diagnosis of sepsis between positive ...
Learning Goals (DeepSeek, 1/29/25) Distinguish Between Innate and Adaptive Immunity. Describe how the innate immune system recognizes common pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) versus the highly specific recognition mechanisms of the adaptive immune system.
Most PAMPs and DAMPs serve as so-called 'Signal 0s' that bind specific receptors [Toll-like receptors, NOD-like receptors, RIG-I-like receptors, AIM2-like receptors, and the receptor for advanced glycation end products (RAGE)] to promote autophagy. Autophagy, a conserved lysosomal degradation pathway, is a cell survival mechanism invoked in ...

The major difference in the immune systems between plants and mammals is that plants lack an adaptive immune system, ... PTI is the first line of defense in plants and is triggered by PAMPs to initiate signaling throughout the plant that damage has occurred to a cell. Along with the PTI, DAMPs are also released in response to this damage, but ...
All the articles were read, and their bibliographies were checked to select other reputed and relevant works based on the opinion of the authors. In the second phase, we focused on the research, with the same criteria, of evidence regarding PAMPs and DAMPs in the single microareas explored in the review (e.g., “DAMPs OR PAMPs AND endothelium).
substantially altering the fundamental differences (7-10,21). The above two models of activation of immune cells have been adapted by the inflammation community over the years to explain two types of host inflammatory responses in vivo – first, inflammation mediated by ... between PAMPs and DAMPs from literature are summarized below (it is ...
Understanding the Difference Between DAMPS and PAMPS. In immunology, DAMPS (Damage-Associated Molecular Patterns) and PAMPS (Pathogen-Associated Molecular Patterns) play crucial roles in the body's immune response. Here are the key differences between them: DAMPS. Source: DAMPS are endogenous molecules released from damaged or dying cells.
There are other concepts of the relations between MAMPs/PAMPs and DAMPs. For example, Garg and Agostinis [ 194 ] have recently rationalized in the context of the ICD of cancer cells that PAMPs in their own are danger-signalling molecules to elicit PRR-mediated innate immune responses via activation of transcription factors.
They recognize microbes or tissue damage by specific molecular structures called pathogen-associated molecular patterns (PAMPs) or DAMPs (10,22). The main functions of PRRs are to stimulate phagocytosis and mediate inflammation by sensing various pathogens and molecules from damaged cells ( 2 , 23 ).
PAMPs and DAMPs bind to pattern-recognition receptors or PRRs associated with body cells to induce innate immunity.

A major focus in this issue of Journal of Innate Immunity is the role of pattern recognition receptors and molecules (PRRs and PRMs), pathogen-associated molecular patterns (PAMPs), and danger-associated molecular patterns (DAMPs) in inflammatory diseases. The clinical importance of these molecules is shown in a study by Marco B. Hansen and coworkers, who report that the reduced levels of PRMs ...
PAMPs are derived from micro-organisms and drive inflammation in response to infections. One well-known PAMP is lipopolysaccharide (LPS), which is found on the outer cell wall of gram-negative bacteria. DAMPs are derived from host cells including tumor cells, dead or dying cells, or products released from cells in response to stress such as hypoxia.
The plant DAMPs will be presented in the context of plant MAMPs and NAMPs, as well as animal DAMPs. Keywords: DAMPs, PAMPs, MAMPs, NAMPs, Innate immunity, Defense, Salicylic acid, Receptors. Background. All living organisms have evolved ways to protect themselves against abiotic and biotic assaults. For example, microbes utilize DNA restriction ...
