The aim of this project is to address the challenge that current treatments for atopic dermatitis (AD) only work as long as they are given.  

A subgroup of the so-called tissue-resident memory (Trm) T-cells appears to be absent in healthy controls and in patients, who have outgrown their AD, but is still present at least a year after a successful clinical outcome following treatment with dupilumab.  

Using state-of-the-art single-cell sequencing methods combined with advanced flow cytometry and so-called suction blistering for collecting sample material, the project will characterize the composition of cells and proteins within skin lesions of AD patients. Compared to most other approaches, this multi-omics approach is expected to provide a much more accurate reflection of what is going on in this complex disease which shows considerable heterogeneity from patient to patient.  

The present project is an extension of a project previously supported by the LEO Foundation (LF18098) where Patrick Brunner successfully refined and validated his sample collection methods. The present project may guide future targeted AD treatment approaches in a more personalized and stratified manner and may offer a relatively short way from bench to bedside.
