Bilayered skin equivalent mimicking psoriasis as predictive tool for preclinical treatment studies.

ABSTRACT: Psoriasis is a prevalent, inflammatory skin disease without cure. Further research is required to unravel dysregulated processes and develop new therapeutic interventions. The lack of suitable in vivo and in vitro preclinical models is an impediment in the psoriasis research. Recently, the development of 3D skin models has progressed including replicas with disease-like features. To investigate the use of in vitro models as preclinical test tools, the study focused on treatment responses of 3D skin replicas. Cytokine-priming of skin organoids induced psoriatic features like inflammation, antimicrobial peptides (AMP), hyperproliferation and impaired differentiation. Topical application of dexamethasone (DEX) or celastrol (CEL), a natural anti-inflammatory compound reduced the secretion of p
