Inflammation in AD Skin Is Driven by an Outside-In/Inside-Out Process
- Immune dysregulation involves the activation of type 2 T-helper (Th2) cells and subsequent inflammatory signaling2
- Skin-barrier dysfunction results in inflammatory signaling due to antigen penetration of AD skin2
- Resulting chronic inflammation further contributes to both skin-barrier dysfunction and immune dysregulation2
Th2 cytokines are the key drivers of inflammation in AD for non-lesional, acute lesional, and chronic lesional skin.3
