Summary : The exact role of epidermal fatty acid binding protein (E-FABP) in skin is unknown. A restoration of the barrier function may be associated with an upregulation of E-FABP. Moreover, E-FABP is upregulated in a variety of cells in response to oxidative stress. A recent observation that dithranol induced irritation is not associated with skin barrier impairment prompted us to investigate the expression of E-FABP in this skin condition to elucidate the unknown function of this protein in skin. This study shows lack of E-FABP upregulation after a single application of dithranol on uninvolved skin of patients with psoriasis. The expression of E-FABP in dithranol irritation correlates with the unimpaired skin barrier function as assessed by measurements of TEWL. Furthermore, we did not find evidence for the recently introduced hypothesis that E-FABP functions as an antioxidant protein in the skin irritation induced by dithranol as oxidative stressor. |
