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

*Objective SCORAD does not include the subjective items daily pruritus and sleeplessness.

Overall, the growing body of evidence supporting the relative overexpression of IL-13 in lesional skin suggests that AD is driven by IL-13 rather than IL-41-3
