Official title: Defining the role of IL-18 in atopic dermatitis
Funded at Washington University · NIH-11064050 · Data updated 2026-11-12
This study is looking at how a substance called IL-18 affects atopic dermatitis, a skin condition that causes itching and inflammation, to help find new ways to treat it.

Who could benefit from this research
✓Could help
Ideal candidates for this research include individuals of all ages suffering from moderate to severe atopic dermatitis.
✕Less likely to help
Patients with mild atopic dermatitis or those not experiencing significant allergic inflammation may not benefit from this research.
What this research studies
This research investigates the role of interleukin-18 (IL-18) in atopic dermatitis, a common skin condition characterized by chronic inflammation and itching. The study aims to understand how IL-18 influences the activation of immune cells, particularly basophils and group 2 innate lymphoid cells (ILC2s), which are known to produce type 2 cytokines that drive allergic responses. By analyzing skin samples and using advanced techniques like single-cell RNA sequencing, researchers hope to uncover the mechanisms by which IL-18 contributes to the symptoms of atopic dermatitis. This could lead to new therapeutic strategies targeting IL-18 to alleviate the condition.
Why it matters
Potential benefit: If successful, this research could lead to new treatments that specifically target IL-18, potentially reducing symptoms and improving the quality of life for patients with atopic dermatitis.
How similar studies have gone: Previous research has shown promising results in targeting type 2 cytokines for atopic dermatitis, suggesting that exploring IL-18 could be a valuable and novel approach.
