Reconstructed human epidermis for in vitro studies on atopic dermatitis: A review

Abstract

Atopic dermatitis (AD) is a chronic inflammatory skin disease causing a strong impact on quality of life. Its pathophysiology is the result of complex interactions involving immunological, genetic and environmental factors. Although there are several published in vitro three-dimensional models mimicking AD, none of them have taken all these pathophysiological features into account; thus, finding the right model may be complicated. This paper reviews the literature on the different reconstructed epidermis models of AD as well as their relevance. We focused our attention on both the defect of the epidermal barrier and the inflammation linked to the immune system.
