Epidermal Fatty-Acid-Binding Protein in Psoriasis, Basal and Squamous Cell Carcinomas: An Immunohistological Study

Abstract

It is unlikely that E-FABP plays a significant role in FA uptake by basal cells. Our data rather indicate that E-FABP expression is related to the commitment of keratinocyte differentiation and that the putative role of E-FABP should not be restricted to the formation of the skin lipid barrier. Since the pattern of E-FABP expression mimics cellular FA transport, our results suggest that lesional psoriatic skin and oral mucosa have a higher metabolism/transport for FAs than normal and non-lesional psoriatic epidermis.
