Abstract

Corticosterone Cytokine RU486 Sensitization Skin Stress
BALB/c mice were sensitized and challenged on the skin with the contact sensitizer, dinitroflourobenzene. Acute restraint applied before sensitization diminished, whereas restraint administered before challenge enhanced, chemical-induced ear swelling and leukocytic infiltration in the dermis. Administration of RU486, a glucocorticoid receptor antagonist, partially reversed restraint modulation of the ear swelling response in both restraint paradigms. Restraint did not modulate significantly the concentration of TNF-α and IL-1β in ear tissue homogenates. These data show that acute restraint modulates cutaneous sensitization differently than challenge, but the changes are not reflected in TNF-α or IL-lβ production.
