Once a DAMP is released from the cell, it promotes a noninfectious inflammatory response by binding to a pattern recognition receptor (PRR). [4] Inflammation is a key aspect of the innate immune response; it is used to help mitigate future damage to the organism by removing harmful invaders from the affected area and start the healing process. [5]
Inflammation is a generic response, and therefore is considered a mechanism of innate immunity, whereas adaptive immunity is specific to each pathogen. [2] Inflammation is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out ...
Positive acute-phase proteins serve (as part of the innate immune system) different physiological functions within the immune system.Some act to destroy or inhibit growth of microbes, e.g., C-reactive protein, mannose-binding protein, [3] complement factors, ferritin, ceruloplasmin, serum amyloid A and haptoglobin.
The inflammasome was discovered by the team of Jürg Tschopp, at the University of Lausanne, in 2002. [17] [18] In 2002, it was first reported by Martinon et al. [17] that NLRP1 (NLR family PYD-containing 1) could assemble and oligomerize into a structure in vitro, which activated the caspase-1 cascade, thereby leading to the production of pro-inflammatory cytokines, including IL-1β and IL-18.
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.

Pathophysiology is a convergence of pathology with physiology. Pathology is the medical discipline that describes conditions typically observed during a disease state; whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
