  2. Apoptosis - Wikipedia

    en.wikipedia.org/wiki/Apoptosis

    A discussion of every disease caused by modification of the various apoptotic pathways would be impractical, but the concept overlying each one is the same: The normal functioning of the pathway has been disrupted in such a way as to impair the ability of the cell to undergo normal apoptosis.

  3. Cell death - Wikipedia

    en.wikipedia.org/wiki/Cell_death

    Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.

  4. Apoptosome - Wikipedia

    en.wikipedia.org/wiki/Apoptosome

    P53 functions as a tumor suppressor that is involved in preventing cancer and occurs naturally in apoptotic pathways. P53 causes cells to enter apoptosis and disrupt further cell division therefore preventing that cell from becoming cancerous (16).

  5. Neurodegenerative disease - Wikipedia

    en.wikipedia.org/wiki/Neurodegenerative_disease

    Intrinsic apoptotic pathways: Result from mitochondrial release of cytochrome c or endoplasmic reticulum malfunctions, each leading to the activation of caspase-9. The nucleus and Golgi apparatus are other organelles that have damage sensors, which can lead the cells down apoptotic pathways.

  6. Necrosis - Wikipedia

    en.wikipedia.org/wiki/Necrosis

    Even after the initial cause of the necrosis has been halted, the necrotic tissue will remain in the body. The body's immune response to apoptosis, which involves the automatic breaking down and recycling of cellular material, is not triggered by necrotic cell death due to the apoptotic pathway being disabled. [29]

  7. Programmed cell death - Wikipedia

    en.wikipedia.org/wiki/Programmed_cell_death

    There are another two proteins worth mentioning that inhibit the release of cytochrome c in the mitochondria. Bcl-2 and Bcl-xl are anti-apoptotic and therefore prevent cell death. There is a potential mutation that can occur in that causes the overactivity of Bcl-2. It is the translocation between chromosomes 14 and 18.

  8. Immunogenic cell death - Wikipedia

    en.wikipedia.org/wiki/Immunogenic_cell_death

    ICD or immunogenic apoptosis is a form of cell death resulting in a regulated activation of the immune response. This cell death is characterized by apoptotic morphology, [3] maintaining membrane integrity. Endoplasmic reticulum (ER) stress is generally recognised as a causative agent for ICD, with high production of reactive oxygen species ...

  9. Pyroptosis - Wikipedia

    en.wikipedia.org/wiki/Pyroptosis

    It is proposed that both pyroptosis and necroptosis may act as defence systems against pathogens when apoptotic pathways are blocked. [ citation needed ] Summary of the different morphologies, mechanisms and outcomes of three most well-characterized forms of cell death (apoptosis, pyroptosis, and necrosis) [ 10 ] [ 6 ] [ 17 ]
