Zusammenfassung der Projektergebnisse

The aim of the funded project was to identify molecular pathways of clinically meaningful outcomes in patients with psoriasis or atopic dermatitis. The underlying rationale was to acknowledge the heterogeneity of both of these diseases by using human models of patients that suffer from both diseases in parallel. During the ongoing project, this was specified to acknowledging disease heterogeneity by combining lesional transcriptome data with deep clinical phenotyping. Using this approach, it was also possible to expand the hypothesis to further inflammatory skin diseases. We developed an analysis pipeline that allowed to identify genetic signatures of clinically meaningful outcomes and biological processes. This resulted in identification of several new potential targets, both for treatment and diagnostics of inflammatory skin diseases. In parallel, the findings were translated into diagnostic products by development of a microfluidic platform that produces molecular test results fully automated at the point of need. Thus, the project has served as a proof-of-principle for a scientific hypothesis that is currently expanded and followed up as well as a translational approach that might enable us to use the produced scientific results in daily clinical practice.
