S. aureus enterotoxins

Superantigen / disease perpetuator

Expression
Present in polyp tissue
Evidence level
strong

Role in pathogenesis

Staphylococcus aureus enterotoxins act as superantigens, driving polyclonal T-cell activation and local IgE production within polyps. Create a self-sustaining inflammatory niche independent of systemic allergy.
