cytolysis
LowFormal / Technical (scientific, medical)
Definition
Meaning
The dissolution or destruction of a cell, particularly through the rupture of its membrane.
In biology and medicine, the process by which a cell is broken down and its contents are released, often due to external osmotic pressure, immune system attack, or infection.
Linguistics
Semantic Notes
The term is almost exclusively used in biological, medical, and biochemical contexts. It implies a pathological or induced breakdown, not a normal physiological process like apoptosis (programmed cell death).
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage.
Connotations

Learning
Memory Aids
Mnemonic
Think 'CYTO' (cell) + 'LYSIS' (splitting/breaking apart, as in 'analysis'). A cell splitting apart.
Conceptual Metaphor
Often framed as an 'attack' or 'bursting' event.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct cognate 'цитолиз' exists and is used identically in scientific Russian.
Common Mistakes
- Misspelling as 'cytolosis' or 'citolysis'. Confusing it with 'cytoskeleton' or 'cytokinesis'.

FAQ
Frequently Asked Questions
No. Cytolysis is a form of accidental or induced cell rupture, while apoptosis is a controlled, programmed cell death without membrane rupture and subsequent inflammation.
Yes, in the context of the immune system. Natural Killer (NK) cells and the complement system induce cytolysis in infected or cancerous cells as a defence mechanism.
There is no direct single-word antonym. Concepts like 'cell survival', 'cytopreservation', or 'maintenance of cellular integrity' represent the opposite state.
Cell biology, immunology, microbiology, pharmacology, and any field studying cell membrane stability, toxins, or drug delivery systems.
