Cytolysis is spelled with the IPA phonetic transcription /saɪˈtɒlɪsɪs/. The first syllable is pronounced as "sigh" and rhymes with "eye". The "t" in the second syllable is pronounced as a "t" sound, and the "o" is pronounced as a short "o" sound. The final syllable is pronounced as "sis" rhyming with "miss". Cytolysis refers to the destruction or dissolution of a cell through the disruption of its membrane, which can be caused by various factors such as enzymes or osmotic shock.
Cytolysis refers to the biological process in which the plasma membrane of a cell is disrupted or ruptured, resulting in the release of cellular contents into the surrounding environment. This phenomenon is often observed in cells that have been subjected to various harmful conditions such as extreme osmotic pressure, exposure to toxins or chemicals, or attack by certain pathogens, such as bacteria or viruses. Cytolysis can also occur as a result of physical trauma or mechanical damage to the cell.
During cytolysis, the integrity of the cell membrane is compromised, leading to the loss of its structural integrity and control over the movement of molecules in and out of the cell. This disruption causes the cell to lose its ability to maintain its internal environment, leading to an imbalance of ions, nutrients, and other molecules. Consequently, the cell starts to swell due to the influx of water, ultimately leading to the bursting or lysis of the cell.
Cytolysis can have significant implications for both the affected cell and the surrounding tissues or organisms. For instance, in certain pathological conditions, such as certain types of cancer or autoimmune diseases, cytolysis can result in the release of cell components that may trigger an immune response, leading to inflammation or tissue damage. However, in some cases, cytolysis is purposely induced in laboratory settings for various research purposes, such as the extraction of cellular components or the release of certain biologically active molecules.

The word "cytolysis" is derived from two ancient Greek words: "kytos" meaning "cell" and "lysis" meaning "loosening" or "breaking apart".
