abstractsFilaggrin, which is abundant in epidermis and mainly localized in the outer layer of epidermis, plays an important role in the barrier function of epidermis. It has been evidenced that the development of ichthyosis vulgaris and atopic dermatitis is associated with the coding genes of filaggrin. The loss-of-function mutations in filaggrin gene may lead to the absence or decreased expression of epidermal filaggrin, barrier function damage, easier entry of environmental antigens and stimuli into epidermis followed by various pathophysilogical changes.
