Abstract EN

Interferon- (IFN-) λ1 is regarded as a potent bio-active molecule in innate immunity.

However, little is known about its role in chronic spontaneous urticaria (CSU).

We therefore investigated expression of IFN-λ1 in CSU, its cellular location, and its influence on inflammatory cell accumulation by using flow cytometry analysis, skin tissue dispersion, immunohistochemical stain, and a mouse peritoneal inflammation model.

The results showed that level of IFN-λ1 was 2.0-fold higher in plasma of the patients with CSU than the level in healthy control (HC) subjects.

Among leukocytes examined, only CD8+ T cells expressed more IFN-λ1 in CSU blood.

Double labeling immunohistochemical staining revealed that IFN-λ1+ inflammatory cells such as mast cells, eosinophils, B cells, neutrophils, and macrophages were mainly located in dermis, whereas epidermis tissue highly expressed IFN-λ1.

IFN-λ1 induced a dose-dependent increase in number of eosinophils, lymphocytes, mast cells, macrophages, and neutrophils in the peritoneum of mice at 6 h following injection, which was inhibited by pretreatment of the animals with anti-intercellular adhesion molecule- (ICAM-) 1 and/or anti-L-selectin antibodies.

In conclusion, IFN-λ1 is likely to play a role in the pathogenesis of CSU.

Blocking IFN-λ1 production may help to reduce the accumulation of inflammatory cells in the involved CSU skin.
