Cytotoxin

A cytotoxin is a substance produced by certain bacteria, cells, or toxins that damages or destroys other cells. These toxins interfere with normal cell functions by disrupting their membranes, enzymes, or internal structures, leading to cell death or malfunction. Cytotoxins play a role in how some bacteria cause disease, such as damaging tissues or impairing immune responses. They can vary in potency and mechanism, but generally, their main effect is to harm or kill cells, contributing to infection severity and symptoms.
