  2. Severe cutaneous adverse reactions - Wikipedia

    These proteins are taken up by antigen-presenting cells (APC) and degraded into small peptides. The peptides are inserted into a groove on HLA proteins that are part of major histocompatibility complexes (i.e. MHC) and presented to T-cell receptors (TCR) on nearby cytotoxic T cells (i.e. CD8 + T cells) or T helper cells (i.e. CD4 + T cells). T ...

  3. Wound healing - Wikipedia

    en.wikipedia.org/wiki/Wound_healing

    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.

  4. Fibrosis - Wikipedia

    en.wikipedia.org/wiki/Fibrosis

    Fibrosis, also known as fibrotic scarring, is a pathological wound healing in which connective tissue replaces normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodelling and the formation of permanent scar tissue.

  5. Damage-associated molecular pattern - Wikipedia

    en.wikipedia.org/wiki/Damage-associated...

    Many DAMPs are nuclear or cytosolic proteins with defined intracellular function that are released outside the cell following tissue injury. [7] This displacement from the intracellular space to the extracellular space moves the DAMPs from a reducing to an oxidizing environment, causing their functional denaturation , resulting in their loss of ...

  6. Putrefaction - Wikipedia

    en.wikipedia.org/wiki/Putrefaction

    Protein hydrolysis is accelerated as the anaerobic bacteria of the digestive tract consume, digest, and excrete the cellular proteins of the body. Putrefaction in human hands after several days of one of the Oba Chandler victims underwater in Florida, United States. The bacterial digestion of the cellular proteins weakens the tissues of the body.

  7. Wound dehiscence - Wikipedia

    en.wikipedia.org/wiki/Wound_dehiscence

    Wound dehiscence is a surgical complication in which a wound ruptures along a surgical incision. Risk factors include age, collagen disorder such as Ehlers–Danlos syndrome , diabetes , obesity , poor knotting or grabbing of stitches , and trauma to the wound after surgery.

  8. Scar - Wikipedia

    en.wikipedia.org/wiki/Scar

    Scar tissue is composed of the same protein as the tissue that it replaces, but the fiber composition of the protein is different; instead of a random basketweave formation of the collagen fibers found in normal tissue, in fibrosis the collagen cross-links and forms a pronounced alignment in a single direction. [1]

  9. Cell damage - Wikipedia

    en.wikipedia.org/wiki/Cell_damage

    Apoptosis is the programmed cell death of superfluous or potentially harmful cells in the body. It is an energy-dependent process mediated by proteolytic enzymes called caspases, which trigger cell death through the cleaving of specific proteins in the cytoplasm and nucleus. [13] The dying cells shrink and condense into apoptotic bodies.
