Pharmacokinetics of Tacrolimus Ointment: Clinical Relevance
Atopic dermatitis is a common inflammatory skin disease whose pathophysiology is not completely understood. Evidence now strongly points to a role for T cells and their cytokines in many phases of atopic dermatitis. Both immediate and delayed hypersensitivity seem to be involved, although how they intertwine remains a complex issue. Th2 cells appear most important in the early stages of atopic lesion development, as their cytokines (IL-4, IL-5 and IL-13) induce eosinophil proliferation and IgE production. The binding of allergen to IgE on mast cells triggers the release of mast cell mediators. When allergen-IgE complexes attach to the FCεRI and FCεRII receptors on Langerhans cells, the magnitude of the response is multiplied.
