The purpose of this study is to investigate proteins found in the skin of people with atopic dermatitis and compare them to those without the condition. This study also aims to understand the functions of a protein called IL-33 in skin cells from patients with atopic dermatitis, those with psoriasis, and healthy individuals. IL-33 is a protein that plays a role in the body's immune response.
During the study, participants will undergo procedures to collect skin samples. These samples will be analyzed to study the proteins and the role of IL-33. Participants will be compensated for their involvement in the study.
- Who can participate: Individuals with active atopic dermatitis or plaque psoriasis who have not recently used systemic immunosuppressants and do not have a history of abnormal scarring or allergies to certain anesthetics are eligible.
- Study details: Participants will provide skin samples for analysis. The study will compare these samples to understand protein functions. A placebo is not involved in this study.
