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

  • IL-13 protein levels in skin-derived interstitial fluid (ISF) correlates with disease severity as measured by objective SCORAD1

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

Overall, the growing body of evidence supports that IL-13 is a primary cytokine involved in driving skin inflammation in AD1-3
