IPA: //saɪˈtɒlɪsɪn//
KK: /sɪˈtɑːlɪsɪn/
A substance that can break down or destroy cells, often used in the context of antibodies that target bacteria.
The cytolysin produced by the immune system helps to eliminate harmful bacteria.
Cytolysin is formed from "cyto-" (from Greek "kytos", meaning cell) and "lysin" (from Greek "lysis", meaning to loosen or dissolve). The word refers to a substance that causes the dissolution or destruction of cells.
Think of 'cyto-' meaning 'cell' and 'lysin' meaning 'to dissolve' — this helps you remember that cytolysin is something that dissolves or destroys cells.
