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.
-Cytosis is a suffix that either refers to certain aspects of cells ie cellular process or phenomenon or sometimes refers to predominance of certain type of cells. It essentially means "of the cell". It essentially means "of the cell".
Dying cells are engaged in a process that is reversible until a first irreversible phase or "point-of-no-return" is trespassed. Necrosis is an unprogrammed death of cells, which involves early plasma membrane changes leading to loss of calcium and sodium imbalance. This causes acidosis, osmotic shock, clumping of chromatin and nuclear pyknosis.

Programmed cell death (PCD; sometimes referred to as cellular suicide [1]) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. [ 2 ] [ 3 ] PCD is carried out in a biological process , which usually confers advantage during an organism's lifecycle .
A man accused of attacking a Colorado reporter after questioning whether he was a citizen and saying “This is Trump’s America now” has had mental health issues for years, his lawyer said.
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.
