The epidermal cells malfunction as a consequence, resulting in thickening of the epidermis (acanthosis), excess production of keratin, and scaling. The outer epidermal layer of the skin, the stratum corneum, normally forms an impermeable barrier that protects the living cells beneath from environmental irritants and toxins. In atopic dermatitis, this outer barrier is impaired. There is an increase in the water loss and a decrease in water binding, which has been attributed to decreased functionality of filaggrin proteins in the skin, which leads to a brittle outer barrier.  These abnormalities can include elevated serum IgE levels (seen in 85% of affected individuals), hypereosinophilia, reduced cell-mediated immunity and antibody-dependent cellular cytotoxicity, slowed chemotaxis of neutrophils and monocytes, a relative increase in the number of CD4-positive (CD4+) Th2 helper T cells that secrete interleukin (IL)-4, and a decrease in CD4+ T helper cells that secrete interleukin-2 (IL-2).
