Glucocorticoids promote CCL20 expression in keratinocytes

Abstract excerpt

BACKGROUND: Glucocorticoids (GCs) are generally envisioned as immunosuppressive, but in conditions such as rosacea and perioral dermatitis they can lead to increased skin inflammation. In lung epithelia, GCs promote expression of the proinflammatory cytokine CCL20, which contributes to steroid-resistant asthma.
