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.

Failure to remove all of the damaged cells and pathogens may retrigger inflammation. The two subsets of macrophage M1 & M2 plays a crucial role in this phase, M1 macrophage being a pro inflammatory while as M2 is a regenerative and the plasticity between the two subsets determine the tissue inflammation or repair.

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.

Fibrosis can occur in many tissues within the body, typically as a result of inflammation or damage. Common sites of fibrosis include the lungs, liver, kidneys, brain, and heart: Micrograph showing cirrhosis of the liver. The tissue in this example is stained with a trichrome stain, in which fibrosis is colored blue.
Inflammation is an important and growing area of biomedical research and health care because inflammation mediates and is the primary driver of many medical disorders and autoimmune diseases, including ankylosing spondylitis, psoriasis, psoriatic arthritis, Behçet's disease, rheumatoid arthritis, inflammatory bowel disease (IBD), and allergy ...
Due to inflammation occurring in pancreatitis, proinflammatory cytokines secreted into the bloodstream can cause inflammation throughout the body, including the lungs and can manifest as ARDS. Because pancreatitis can cause lung injury and affect normal lung function, supplemental oxygen is occasionally delivered through breathing tubes that ...
Among the PGs, anti-inflammatory PGE2 and pro-inflammatory PGD2 increase the most after activation, with PGE2 increasing expression of IL-10 and inhibiting production of TNFs via the COX-2 pathway. [35] [36] Neutrophils are among the first immune cells recruited by macrophages to exit the blood via extravasation and arrive at the infection site ...
