Expression levels of IL-13 in lesional skin correlates with disease severity. 1,2

IL-13 mRNA Expression in Lesional Skin Correlates With SCORAD

mRNA expression levels of IL-13 in lesional skin were correlated with disease severity, as measured by SCORing Atopic Dermatitis (SCORAD)1

Chart created by showing IL-13 mRNA expression in lesional skin and correlation with SCORAD

IL-13 Protein Levels in Lesional Skin Correlate With Objective SCORAD*

Based on IL-13 protein levels in skin-derived interstitial fluid (ISF), a strong correlation with disease severity as measured by objective SCORAD was established


Overall, the growing body of evidence supports that IL-13 is a primary cytokine involved in driving skin inflammation in AD.1-3
