New discovery of suppressive secretoglobin 1A1 in cells of the lower airways.

Anti-inflammatory mechanisms from immune cells are intensively investigated. Here Uli Zissler and colleagues describe that SCGB1A1, an epithelial anti-inflammatory mediator is playing a role in allergen specific immunotherapy.

While several systemic immunomodulatory effects of allergen-specific immunotherapy (AIT) have been discovered, local anti-inflammatory mechanisms in the respiratory tract are largely unknown. We sought to elucidate local and epithelial mechanisms underlying allergen-specific immunotherapy in a genome-wide approach. Allergen-specific immunotherapy induces a yet unknown local gene expression footprint in the lower airways that on one hand appears to be a result of multiple regulatory pathways and on the other hand reveals SCGB1A1 as novel anti-inflammatory mediator of long-term allergen-specific therapeutic intervention in the local environmen
