1034 Lipoxin A4 diminishes mast cell activation and allergic contact hypersensitivity

Atopic dermatitis (AD) is characterized by type 2 cytokines in lesional skin. In AD, IgE-activated dermal mast cells may perpetuate type 2 dysregulation through the release of inflammatory granules and de novo transcribed cytokines. Current MC-therapies primarily target granule release and have limited success in AD treatment, necessitating exploration for improved MC-targeting agents. Immunoresolvins, such as lipoxin A4 (LXA4) are therapeutic in murine asthma models, and may be efficacious for treating allergic inflammation in the skin.
